Bug ID: 111142
Summary: [14 regression] ICE in get_group_load_store_type, at
tree-vect-stmts.cc:2121 (AVX512)
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization

compressed unreduced testcase
gcc version 14.0.0 20230824 (experimental)

g++ -m32 -O2 -march=znver4 -c gcc-14-mesa-aco-ice.ii
during GIMPLE pass: vect
../mesa-9999/src/amd/compiler/aco_insert_waitcnt.cpp: In function 'void
aco::insert_wait_states(Program*)':
../mesa-9999/src/amd/compiler/aco_insert_waitcnt.cpp:1042:1: internal compiler
error: in get_group_load_store_type, at tree-vect-stmts.cc:2121
can only trigger with "-march=znver4", does not trigger with avx2 only or -O1
or lower.
Fails with the same error for x64-64, but the testcase is preprocessed for
32bit targets.
Thank you!
