[Bug target/100762] [mips+msa] ICE when comparing 64 bit vectors
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100762 --- Comment #5 from CVS Commits --- The master branch has been updated by Xi Ruoyao : https://gcc.gnu.org/g:82625a42e652d52fc6bbe6070f8d0589d5e0c8ad commit r12-2183-g82625a42e652d52fc6bbe6070f8d0589d5e0c8ad Author: Xi Ruoyao Date: Fri Jun 18 20:11:42 2021 +0800 mips: check MSA support for vector modes [PR100760,PR100761,PR100762] Check if the vector mode is really supported by MSA in certain cases, instead of testing ISA_HAS_MSA. Simply testing ISA_HAS_MSA can cause ICE when MSA is enabled besides other MIPS SIMD extensions (notably, Loongson MMI). gcc/ PR target/100760 PR target/100761 PR target/100762 * config/mips/mips.c (mips_const_insns): Use MSA_SUPPORTED_MODE_P instead of ISA_HAS_MSA. (mips_expand_vec_unpack): Likewise. (mips_expand_vector_init): Likewise. gcc/testsuite/ PR target/100760 PR target/100761 PR target/100762 * gcc.target/mips/pr100760.c: New test. * gcc.target/mips/pr100761.c: New test. * gcc.target/mips/pr100762.c: New test.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100762 --- Comment #3 from Xi Ruoyao --- There is some strange interaction between -mmsa and -mloongson-mmi causing this. It can be reproduced by building pixman (which enables -mloongson-mmi by default) with -mmsa.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100762 --- Comment #1 from Evan Nemerson --- It's not just comparisons. <<, >>, /, * also don't work. AFAICT only bitwise operations and +/- work, as well as everything with a 64-bit element type (i.e., a vector of one element)… 8/16/32-bit elements all fail.
