# cc -n32 update info from Krishna Sethuraman, krishna@sgi.com.
# additional update from Scott Henry, scotth@sgi.com
# - tries to check for various compiler versions and do the right
# thing when it can
# - warnings turned off (-n32 messages):
-# 1116 - non-void function should return a value
-# 1048 - cast between pointer-to-object and pointer-to-function
-# 1042 - operand types are incompatible
+# 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
# 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.
