# hints/irix_6.sh
#
# original from Krishna Sethuraman, krishna@sgi.com
#
# Modified Mon Jul 22 14:52:25 EDT 1996
# 	Andy Dougherty <doughera@lafayette.edu>
# 	with help from Dean Roehrich <roehrich@cray.com>.
#   cc -n32 update info from Krishna Sethuraman, krishna@sgi.com.
#       additional update from Scott Henry, scotth@sgi.com

# Futzed with by John Stoffel <jfs@fluent.com> on 4/24/1997
#    - assumes 'cc -n32' by default
#    - tries to check for various compiler versions and do the right 
#      thing when it can
#    - warnings turned off (-n32 messages):
#       1184 - "=" is used where where "==" may have been intended
#       1552 - variable "foo" set but never used

# Tweaked by Chip Salzenberg <chip@perl.com> on 5/13/97
#    - don't assume 'cc -n32' if the n32 libm.so is missing

# Threaded by Jarkko Hietaniemi <jhi@iki.fi> on 11/18/97
#    - POSIX threads knowledge by IRIX version

# gcc-enabled by Kurt Starsinic <kstar@isinet.com> on 3/24/1998

# 64-bitty by Jarkko Hietaniemi on 9/1998

# Martin Pool added -shared for gcc on 2004-01-27

# Use   sh Configure -Dcc='cc -n32' to try compiling with -n32.
#     or -Dcc='cc -n32 -mips3' (or -mips4) to force (non)portability
# Don't bother with -n32 unless you have the 7.1 or later compilers.
#     But there's no quick and light-weight way to check in 6.2.

# NOTE: some IRIX cc versions, e.g. 7.3.1.1m (try cc -version) have
# been known to have issues (coredumps) when compiling perl.c.
# If you've used -OPT:fast_io=ON and this happens, try removing it.
# If that fails, or you didn't use that, then try adjusting other
# optimization options (-LNO, -INLINE, -O3 to -O2, etcetera).
# The compiler bug has been reported to SGI.
# -- Allen Smith <allens@cpan.org>

# Modified (10/30/04) to turn off usemallocwrap (PERL_MALLOC_WRAP) in -n32
# mode - Allen.

# memcmp() is an inlined intrinsic, and "sometimes" it gets compiled wrong.
#
# In Perl the most obvious hit is regcomp.c:S_regpposixcc(),
# causing bus errors when compiling the POSIX character classes like
# /[[:digit:]], which means that miniperl cannot build perl.
# (That is almost only the one victim: one single test in re/pat fails, also.)
#
# Therefore let's turn the inline intrinsics off and let the normal
# libc versions be used instead. This may cause a performance hit
# but a little slower is better than zero speed.
