Tweak configure to attempt to add -qnoansialias to CFLAGS whenever running on AIX with a non-gcc compiler. The previous coding would do this only if CC was exactly "xlc"; which is a bad idea, as demonstrated by trouble report from Mihai Criveti. 2009-02-11 15:02:40 -05:00			`# Set appropriate default compiler options if using xlc`

Rename templates to match names in makefiles/Makefile.* and include/port. Read templates after compiler is detected. Convert all templates to real shell scripts. Rename bsd->openbsd, alpha->osf. 2000-07-15 11:54:52 -04:00			`case $host_os in`

Don't bother adding to cflags/cppflags, just set them because configure handles that, and make solaris debug use no optimization. 2004-12-02 13:11:40 -05:00			`CFLAGS="-O -qmaxmem=16384 -qsrcmsg"`

AIX: Test the -qlonglong option before use. xlc provides "long long" unconditionally at C99-compatible language levels, and this option provokes a warning. The warning interferes with "configure" tests that fail in response to any warning. Notably, before commit 85a2a8903f7e9151793308d0638621003aded5ae, it interfered with the test for -qnoansialias. Back-patch to 9.0 (all supported versions). 2015-07-17 03:01:14 -04:00			`CFLAGS="-O2 -qmaxmem=16384 -qsrcmsg"`

Allow MEMSET_LOOP_LIMIT to be set on a per-platform basis, and turn off MemSet on AIX by setting MEMSET_LOOP_LIMIT to zero. Add optimization to skip MemSet tests in MEMSET_LOOP_LIMIT == 0 case and just call memset() directly. 2006-02-03 08:53:15 -05:00
