1. Please move all psABI bits into ia64.h out of the OS headers.
>From rth's recent commit, patch #1 should be tested and committed to
mainline and 3.1 by an IA-64 maintainer (who are most knowledgeable about
this platform, GCC, and can test on ia64 hardware). Patch #1 corrects a
bug in which ia64-*-FreeBSD does not have the psABI specified "_LP64"
define.
2. Can ia64-*-elf tolerate DONT_USE_BUILTIN_SETJMP and
PROFILE_BEFORE_PROLOGUE? Since every target except ia64-*-elf defines
these I am lead to believe the psABI may be behind these settings. Or is
this a difference between hosted and embedded? If so the knobs should be
moved to sysv4.h instead.
If the change is OK for ia64-*-elf, IA-64 maintainers (who are most
knowledgeable about this platform and can test on it) please patch #2 or
something simular for 3.2 and 3.1:
