(MIPSpro 7.4.4m on IRIX 6.5.30)
According to the mk/defaults/mk.conf file, the correct values for 'ABI' are "64 (64 bit ABI), 32 (SGI's N32 ABI), undefined (SGI's old o32 ABI)"
However, the update transform-mipspro-cc has:
-64 ) if [ $arg = "-$wrapper_abi" ]; then
transform_fail "Wrong ABI argument $arg for ABI $wrapper_abi."
... which will fail for the most common configuration - n32 (since '-n32' != '-32').
There is a mismatch here between what mk.conf expects (ABI='32' for n32) and what transform-mipspro-cc expects (ABI='n32' for n32).
Additionally, also in transform-mipspro-cc, when filtering -O options, '-OPT:*' should also be allowed.
Attempt to build any software with ABI=32 (to enable n32 ABI) on IRIX.
With the mk.conf documentation needs to be updated to state ABI="n32" for n32 (which would be more obvious, but could lead to regressions), or alter the logic in transform-mipspro-cc to treat '-n32' differently from '-32' and '-64'.
(Background: -n32 enables the canonical default ABI for IRIX 6.x; -32 is the "old" 32bit ABI which is only used to IRIX 5.x compatibility)
