This chapter describes some of the differences and restrictions you might encounter when porting the HP C++ compiler to an I64 system. For a summary of new and changed features supported by this version of the compiler on both OpenVMS Alpha and I64 systems, see the Preface of this manual. For any known issues, see the C++ release notes.
HP C Version 7.1 for OpenVMS I64 uses a new technology base that differs substantially from HP C++ for OpenVMS Alpha and HP C for OpenVMS I64. Although a great deal of work has been done to make it highly compatible with HP C++ for OpenVMS Alpha, there are a number of differences that you will likely notice. Among them are:
This section describes porting considerations for the C++ compiler for OpenVMS I64 systems. See Section 4.2 for considerations for the standard library, language run-time support library, and class library.
The move from Alpha systems to I64 systems may cause some minor differences in certain compiler diagnostics that are signaled from the code generator. As a result, diagnostics for unreachable code and fetches of uninitialized variables might be different on the two platforms. In addition to a change in message text, some conditions detected on one platform might not be detected on the other.
There have also been some changes in the /WARNINGS qualifier for both platforms. These include bug fixes and improved compatibility with the C compiler. For a summary of these changes, see the New and Changed Features section of the Preface.
The C++ compiler for I64 systems is built from a different code base than the C++ compiler for Alpha systems, and that code base is larger than the code base for Alpha. Also, I64 images tend to be somewhat larger than Alpha images in general. Image size mostly affects working-set size and the amount of pagefile quota needed to execute an image without exhausting virtual memory. If you find that programs that compile and run successfully on Alpha run out of memory on I64 systems (either during compilation or when run), you probably need to increase your pagefile quota. There are no specific guidelines at this time. You might start by doubling the quota that was sufficient on Alpha, and then use a "binary-search" approach to arrive at a better quota value for I64 systems (doubling again, or halving the increment, until your biggest programs and compilations have just enough memory, and then adding an appropriate safety margin).
Some of the compiler dialects (options to the /STANDARD qualifier) have been updated to reflect the most recent behaviors of the compilers that the dialect is attempting to match. Other changes involve the removal of less significant or undesirable compatibility features.
The object model and the name mangling scheme used by the C++ compiler on I64 systems are different from those used on Alpha systems (different from both /MODEL=ARM and /MODEL=ANSI). The I64 compiler uses the interface described by the I64 Application Binary Interface (ABI).
See http://www.codesourcery.com/cxx-abi/abi.html for a draft description of the ABI specification.
The C++ compiler has some additional encoding rules that are applied to symbol names after the ABI name mangling is determined. All symbols with C++ linkage have CRC encodings added to the name, are uppercased and shorten to 31 characters if necessary. Since the CRC is computed before the name is uppercased, the symbol name is case-sensitive even though the final name is in uppercase. /NAMES=AS_IS and /NAMES=UPPER are not applicable to these symbols.
All symbols without C++ linkage will have CRC encodings added if they are longer then 31 characters and /NAMES=SHORTEN is specified. Global variables with C++ linkage are treated as if they have non-C++ linkage for compatibility with C and older compilers.
This section describes C++ command-line qualifier differences to be aware of on I64 systems.
Qualifiers/Features Not Supported on I64 Systems
The following command-line qualifiers and features are not supported on C++ for I64 systems, and are diagnosed by default because ignoring them is likely to alter program behavior:
A number of other qualifiers not supported on I64 systems are, by default, silently ignored by the compiler. These qualifiers fall into two groups:
Two optional compiler messages can be enabled to diagnose most of these cases:
If you encounter porting problems, compile /WARN=ENABLE=QUALCHANGE to determine if a qualifier change might be affecting your application.
If you wish to clean up your build scripts to remove extraneous qualifiers that are not meaningful on I64 systems, you can enable the QUALNA message.
A list of these qualifiers follows:
NORTTI_CTORVTBLS
NOPOINTERS_TO_GLOBALS
TRUSTED_SHORT_ALIGNMENT
WHOLE_PROGRAM
/DEBUG=NOSYMBOLS
/DEBUG=NOTRACEBACK
The following command-line qualifier is new for C++ Version 7.1:
This section describes floating-point behavior on I64 systems.
IEEE Now the Default
On OpenVMS I64 systems, /FLOAT=IEEE_FLOAT is the default floating-point representation. IEEE format data is assumed and IEEE floating-point instructions are used. There is no hardware support for floating-point representations other than IEEE, although you can specify the /FLOAT=D_FLOAT or /FLOAT=G_FLOAT compiler option.
These VAX floating-point formats are supported in the I64 compiler by generating run-time code that converts VAX floating-point formats to IEEE format to perform arithmetic operations, and then converts the IEEE result back to the appropriate VAX floating-point format. This imposes additional run-time overhead and some loss of accuracy compared to performing the operations in hardware on Alpha and VAX systems. The software support for the VAX formats is provided to meet an important functional compatibility requirement for certain applications that need to deal with on-disk binary floating-point data.
On I64 systems, the default for /IEEE_MODE is DENORM_RESULTS, which is a change from the default of /IEEE_MODE=FAST on Alpha systems. This means that by default, floating-point operations may silently generate values that print as Infinity or Nan (the industry-standard behavior), instead of issuing a fatal run-time error as they would when using VAX floating-point format or /IEEE_MODE=FAST. Also, the smallest-magnitude nonzero value in this mode is much smaller because results are allowed to enter the denormal range instead of being flushed to zero as soon as the value is too small to represent with normalization.
The conversion between VAX floating-point formats and IEEE formats on the Intel Itanium architecture is a transparent process that will not impact most applications. All you need to do is recompile your application. Because IEEE floating-point format is the default, unless your build explicitly specifies VAX floating-point format options, a simple rebuild for I64 systems will use the native IEEE formats directly. For the large class of programs that do not directly depend on the VAX formats for correct operation, this is the most desirable way to build for I64 systems.
When you compile an OpenVMS application that specifies an option to use VAX floating-point on an I64 system, the compiler automatically generates code for converting floating-point formats. Whenever the application performs a sequence of arithmetic operations, this code does the following:
Where no arithmetic operations are performed (VAX float fetches followed by stores), no conversion will occur. The code handles such situations as moves.
VAX floating-point formats have the same number of bits and precision as their equivalent IEEE floating-point formats. For most applications, the conversion process will be transparent and, therefore, a non-issue.
In a few cases, arithmetic calculations might have different results because of the following differences between VAX and IEEE formats:
These differences might cause problems for applications that do any of the following:
You can test an application's behavior with IEEE floating-point values by first compiling it on an OpenVMS Alpha system using /FLOAT=IEEE_FLOAT/IEEE_MODE=DENORM.
If that produces acceptable results, then simply build the application on the OpenVMS I64 system using the same qualifier.
If you determine that simply recompiling with an /IEEE_MODE qualifier is not sufficient because your application depends on the binary representation of floating-point values, then first try building for your I64 system by specifying the VAX floating-point option that was in effect for your VAX or Alpha build. This causes the representation seen by your code and on disk to remain unchanged, with some additional runtime cost for the conversions generated by the compiler. If this is not an efficient approach for your application, you can convert VAX floating-point binary data in disk files to IEEE floating-point formats before moving the application to an I64 system.
/IEEE_MODE Notes
On Alpha systems, the /IEEE_MODE qualifier generally has its greatest effect on the generated code of a compilation. When calls are made between functions compiled with different /IEEE_MODE qualifiers, each function produces the /IEEE_MODE behavior with which it was compiled.
On I64 systems, the /IEEE_MODE qualifier primarily affects only the setting of a hardware register at program startup. In general, the /IEEE_MODE behavior for a given function is controlled by the /IEEE_MODE option specified on the compilation that produced the main program: the startup code for the main program sets the hardware register according the command-line qualifiers used to compile the main program.
When applied to a compilation that does not contain a main program, the /IEEE_MODE qualifier does have some effect: it might affect the evaluation of floating-point constant expressions, and it is used to set the EXCEPTION_MODE used by the math library for calls from that compilation. But the qualifier has no effect on the exceptional behavior of floating-point calculations generated as inline code for that compilation. Therefore, if floating-point exceptional behavior is important to an application, all of its compilations, including the one containing the main program, should be compiled with the same /IEEE_MODE setting.
Even on Alpha systems, the particular setting of /IEEE_MODE=UNDERFLOW_TO_ZERO has the following characteristic: its primary effect requires the setting of a runtime status register, and so it needs to be specified on the compilation containing the main program in order to be effective in other compilations.
More Information
For more information on I64 floating-point behavior, see the white paper OpenVMS floating-point arithmetic on the Intel Itanium architecture at http://www.hp.com/products1/evolution/alpha_retaintrust/download/i64-floating-pt-wp.pdf .
The C++ built-in functions available on OpenVMS Alpha systems are also available on I64 systems, with some differences. Section C.2 documents these differences and describes the built-in functions that are specific to I64 systems.
On OpenVMS Alpha systems, the C++ compiler uses a proprietary object format specific to OpenVMS.
On OpenVMS I64 systems, the compiler generates ELF objects. ELF is an industry standard object format used on many UNIX platforms, including Linux. This change should be transparent to most users; it is primarily of interest to compiler and tools developers. The greatest benefit of this change is that it should make it easier to create development tools that work on OpenVMS and other platforms.
Extensions to ELF have been used as needed to provide functionality unique to OpenVMS. See the Porting Applications from HP OpenVMS Alpha to HP OpenVMS Industry Standard 64 for Integrity Servers for more information on ELF.
COMDATS/Group Sections
One feature that ELF provides that is new to OpenVMS is the COMDAT section group---a group of sections in an object file that can be duplicated in one or more other object files. The linker is expected to keep one group and ignore all others. The benefit of this feature is that it permits compilers to generate definitions for symbols for things used in multiple objects without having to worry about creating a single definition in one place. The most notable uses for this feature are templates and inline functions.
New ELF Type for Weak Symbols
A new Executable and Linkable Format (ELF) type was generated to distinguish between the two types of weak symbol definitions.
For modules with ABI versions equal to 2 (the most common version used by compilers):
The Librarian supports both the ELF ABI versions 1 and 2 of the object and image file formats within the same library.
This section describes template instantiation for I64 systems.
Implemented using ELF COMDATS/Groups Sections
The Alpha C++ compiler had numerous models for instantiating templates. Each attempted to solve the issue of how to generate one and only one copy of each template. The use of ELF on OpenVMS I64 systems provided the compiler with the additional option of using COMDAT section groups. Since this technique is superior to all the models supported on Alpha, this is the only model supported on I64 systems.
In this model, templates are instantiated in a COMDAT section group inside every object module that uses them. This is very similar to the /TEMPLATE=LOCAL on Alpha systems, except that when the objects are linked together, the linker removes the duplicate copies. The primary advantage of this technique over /TEMPLATE=LOCAL and /TEMPLATE=IMPLICIT_LOCAL is the reduction in image size.
A secondary advantage is the elimination of distinct data for each template. For example, if a template maintained a list of elements it created, each module would have a separate copy of the list. This behavior does not conform to the standard. If you are currently using /TEMPLATE=LOCAL or /TEMPLATE=IMPLICIT_LOCAL, you will likely experience no difficulty from this change.
Not in Repository
The most visible difference that results from this new instantiation model occurs in models that instantiate templates into the repository (/TEMPLATE=AUTOMATIC|ALL_REPOSITORY|USED_REPOSITORY).
With the new model, no repository is needed. Build procedures that use CXXLINK will work transparently. Builds that attempt to manipulate objects in the repository will fail and will need to be changed. In most cases, the reason for manipulating the repository directly has been eliminated with the new template instantiation model.
Also see Chapter 5.
The command-line option /EXCEPTIONS=NOCLEANUP is not implemented. As a result, you might see destructors being called during cleanup in code previously compiled with this option.
Exception specifications are not implemented. Exception specifications on routine declarations and definitions are accepted syntactically, but their run-time behavior has not yet been implemented.
According to the C++ Standard, an implementation may or may not unwind the stack before calling terminate when no matching handler is found for a thrown exception. On I64 systems, the implementation unwinds the stack. On Alpha systems, it does not.
Consider the following program:
#include <exception> #include <cstdio> #include <cstdlib> class C { public: C() { std::printf("Created\n"); } ~C() { std::printf("Destroyed\n"); } }; void announce1() { std::printf("In terminate\n"); exit(0); } int main() { C c; std::set_terminate(announce1); throw 5; return 0; } |
For the above program, the output on OpenVMS Alpha and I64 systems is:
Alpha: I64: Created Created In terminate Destroyed In terminate |
The compiler assumes that the only two ways an exception can be propagated into a function are:
As a result of this assumption, some exceptions such as those thrown from a signal handler will not be caught.
The C++ I64 compiler incorrectly calls terminate() when, during unwinding, the destruction of an object results in an exception, even if this exception is caught within the destructor.
For example, consider the following program:
extern "C" int printf(const char *,...); struct killit { killit () {} ~killit () { try { throw 11; } catch (int i) { printf("caught %d\n", i); } } }; int main () { try { killit local; throw 33; } catch (const int &i) { printf("caught int: %d\n", i); } return 0; } |
The expected output for the above example is:
caught 11 caught int: 33 |
But the executable produced by the C++ I64 compiler calls terminate() .
In cases where the expression to be thrown has been evaluated, but before the exception can be caught: if a called user function such as a copy constructor exits through an uncaught exception, then the compiler incorrectly attempts to match this latter exception object type to the handlers in enclosing try blocks in succession, instead of calling terminate() .
Further, the function uncaught_exception returns FALSE while in the called user function described above.
For example, consider the following program:
extern "C" int printf(const char *,...); extern "C" int exit(int); #include <exception> void announce () { printf("Terminated!\n"); exit(0); } class Y { public: Y () { printf ("construct Y\n"); } Y(Y &rhs) { printf ("copy Y\n"); printf ("uncaught_exception = %s\n", std::uncaught_exception() ? "TRUE" : "FALSE"); throw 20; } ~Y () { printf ("destruct Y\n"); } }; void cxx_func () { Y OBJ2; printf ("In cxx_func\n"); try { throw OBJ2; } catch (const Y &) { printf("Caught Y &\n"); } catch (int i) { printf("Caught %d\n", i); } printf ("leaving cxx_func\n"); } main () { std::set_terminate(announce); cxx_func(); printf ("Leaving main\n"); } |
The expected output in the above example is:
construct Y In cxx_func copy Y uncaught_exception = TRUE Terminated! |
But the executable produced by the C++ I64 compiler outputs:
construct Y In cxx_func copy Y uncaught_exception = FALSE Caught 20 leaving cxx_func destruct Y Leaving main |
The C++ I64 compiler also incorrectly calls terminate() when a destructor invoked during stack unwinding exits with an exception that violates its own exception specification, instead of calling unexpected() .
Consider the following program:
#include <exception> extern "C" void exit(int); extern "C" int printf(const char *,...); void announce2 () { printf("announce2: Unexpected!\n"); exit(0); } void announce1 () { printf("announce1: Terminated!\n"); exit(0); } class C { public: C() { printf("C()\n"); } ~C() throw() { std::set_unexpected(announce2); printf("~C()\n"); throw 3; } }; void foo() { C c; printf("throwing ...\n"); throw 5; } main() { std::set_terminate(announce1); foo(); } |
In the above example, the expected output is:
C() throwing ... ~C() announce2: Unexpected! |
But the executable produced by the C++ I64 compiler outputs:
C() throwing ... ~C() announce1: Terminated! |
When a user-defined unexpected() routine throws or rethrows an exception, the compiler incorrectly checks the exception specification of the caller of the routine instead of that of the routine itself, which did not allow the exception in its exception specification.
Consider the following program:
#include <exception> #include <cstdlib> extern "C" int printf(const char *, ...); void my_unex() { printf("In my unex\n"); throw; } void my_term() { printf("In my term\n"); std::exit(0); } void foo() throw() { // spec not checked with second rethrow printf("In foo\n"); throw 7; } void bar() throw(int) { // this spec checked with second rethrow printf("In bar\n"); foo(); } void foo2() throw(std::bad_exception) { // spec not checked with first rethrow printf("In foo2\n"); throw 5; } int main() { std::set_unexpected(my_unex); std::set_terminate(my_term); try { foo2(); } catch (int i) { printf("Caught %d\n", i); } catch (std::bad_exception &) { printf("Caught bad_exception\n"); } try { bar(); } catch (int i) { printf("Caught %d\n", i); } catch (...) { printf("Caught ...\n"); } return 0; } |
In the above example, expected output is:
In foo2 In my unex Caught bad_exception In bar In foo In my unex In my term |
But the compiler produces:
In foo2 In my unex Caught 5 In bar In foo In my unex Caught 7 |
For I64 systems, the C++ standard library has been upgraded and organized as a shareable image. All applicable fixes and enhancements done in the C++ standard library for Alpha systems, have been applied to the C++ standard library for I64 systems.
The C++ class library on I64 systems is based on the same code as the C++ class library on Alpha systems. The major change in the C++ class library for I64 systems is the removal of the tasks and complex packages.
The standard library, language run-time support library, and class library have been reorganized for I64 systems.
On Alpha systems, the C++ standard library and language run-time support library is delivered in an object library, LIBCXXSTD.OLB, shipped with the compiler kit.
On I64 systems, the C++ standard library and language run-time support library are delivered as separate system shareable images shipped with the base operating system. The names of the images are: CXXL$RWRTL.EXE and CXXL$LANGRTL.EXE, respectively. The images reside in the SYS$LIBRARY directory and are installed at system startup. The LIBCXXSTD.OLB object library does not exist on I64 systems.
On Alpha systems, there are three class library shareable images: CXXL$011_SHR.EXE, CXXL$011_SHRTASK.EXE, and CXXL$011_TASK.EXE.
On I64 systems, the C++ class library continues to ship as a system shareable image. Because the tasks and complex packages have been removed, there is only one class library image: CXXL$011_SHR.EXE.
The language run-time support library no longer validates if a negative value has been specified in a call to operator new . Instead, the value is treated as an unsigned value, and an attempt is made to dynamically allocate the specified memory.
The following class library changes have been made:
This section describes changes to the C++ standard library.
There are two major changes in the C++ standard library for I64 systems as compared with the standard library for Alpha systems:
Additional standard library changes, known issues, and platform differences are noted in the following sections.
While the change in the library distribution model should be transparent to customers (except that application images are much smaller on I64 systems), users on I64 systems may find that the new C++ Standard Library is much less forgiving in terms of including all necessary library headers than the old Standard Library.
For example, the following program compiles cleanly on OpenVMS Alpha systems despite the fact that it does not include the <iostream> header necessary for the std::cout object:
#ifndef __USE_STD_IOSTREAM #define __USE_STD_IOSTREAM #endif #include <fstream> using namespace std; main() { cout << "hello, world"; } |
However, on OpenVMS I64 systems, compilation fails with the following error:
%CXX-E-UNDECLARED, identifier "cout" is undefined |
It is nearly impossible to describe all combinations of library constructs and header files that would compile cleanly on Alpha systems and yet fail to compile on I64 systems because a library header required by the C++ standard for a particular construct has not been included. If a program that used to compile cleanly on an Alpha system fails to compile on an I64 system, it is always a good idea to check that all necessary library headers are included.
A program that includes internal RW stdlib V2.0 library headers, like <stddefs> or <stdcomp> , or that uses internal library macros _RW_*, will have to be modified because the new C++ standard library does not necessarily have the same internal headers or use the same internal macros as the old one.
The following are known issues with C++ for OpenVMS I64 systems:
The following are differences between the I64 and Alpha standard libraries:

Because of changes in the architecture on I64 systems, CXXLINK plays a much smaller role. Its only remaining purpose is to provide human readable (demangled) names for mangled C++ names in diagnostics generated by the linker.
Specific changes are:
