I don't think it must be restricted to system headers, as it is possible that the user 'imports' such a function (and define it in one of VMS favorite languages such as macro-32 or bliss). If it's not restricted to system headers, then probably the option is better than the target hook. I'm not sure I understand the reasoning here. This seems fairly VMS specific so what is the downside for a target hook and user written headers?

On 10/3/2011 1:23 PM, Joseph S. Myers wrote: The language accepted by the compiler in the user's source code (as opposed to in system headers) shouldn't depend on the target except for certain well-defined areas such as target attributes and built-in functions; behaving the same across different systems is an important feature of GCC. This isn't one of those areas of target-dependence; it's generic syntax rather than e.g. exploiting a particular processor feature. I understand now, thanks for explaining.

Re: [VMS/committed]: Add -mpointer-size switch
On 3/12/2012 4:48 AM, Tristan Gingold wrote: Hi, Now that '#pragma pointer_size' is supported by GCC for VMS, we can add the '-mpointer-size' switch (modeled on /POINTER_SIZE=xx DEC-C qualifier) to set the default pointer size. This also makes alpha64-dec-*vms* target obsolete (but still supported by alpha*-dec-*vms*). What about the size of Ada system.address which is also controlled by alpha64 triplet?

Build parts are ok. Paolo Thanks. May I regenerate libiberty/configure and check it in, or does that require a libiberty maintainer? Regarding your question(s) I believe -fpic/PIC is still broken on Interix but I'll have to dig into some old notes to clarify the reason. The comment about shared library relocation is still true.

Also, in alpha.h there are some references to mips-tfile, which is gone with osf. If there are no non-gas configrations remaining, that stuff can go, too. Given that GAS supports VMS, I suspect that all targets are now GAS. I'll let the adacore folks answer that for certain howeverl. All Alpha/VMS targets use GAS. --Doug

Re: [PATCH] Default Alpha/VMS to DWARF2 debugging only
Dwarf2 only works with an ancient GDB. VMS style was useful because it implemented enough to get a trace back. But as you say it’s dead, so no basis for objection.
