bin/package, src/cmd/INIT/package.sh:
- CCFLAGS overwrites the autodetected optimisation flags (e.g. -Os)
if set. Unfortunately, that also happened when we added something
to CCFLAGS for a release build or to add an extra flag needed by
Solaris. The fix is to use a new flags variable (KSH_RELFLAGS)
instead. This needs to be done in a different place as it needs
to be added to the mamake command as an assignment argument.
- Remove the Solaris CCFLAGS hack; see features/common below.
src/*/*/Mamfile:
- Add ${KSH_RELFLAGS} to all the compiler commands.
src/lib/libast/features/common:
- Enable POSIX standard on Solaris (i.e.: if __sun is defined) by
defining _XPG6 directly in the feature test that generates
ast_std.h, which is indirectly included by everything. This
removes the need to pass -D_XPG6 via CCFLAGS. (Doing so
automatically with gcc was not otherwise possible.)
src/cmd/INIT/cc.sol11.*:
- No longer pass -D_XPG6, as per above.
The versions from the Solaris patch require $CC_EXPLICIT to be set,
which is specific to the internal Solaris build environment.
src/cmd/INIT/cc.sol11.*:
- Cope without $CC_EXPLICIT set in environment; fall back to $CC
and if that is not set either, detect whether to use cc or gcc.
- Set appropriate flags for cc (Solaris Studio) or gcc, including
the necessary -D_XPG6 flag, without which ksh crashes on Solaris.
bin/package, src/cmd/INIT/package.sh:
- Update hack to add the -D_XPG6 flag so it applies to gcc only
(note: the src/cmd/INIT/cc.* scripts are never used for gcc).
