Bug ID: 115931
Summary: mips: vec_pack_usat_m's pattern is wrong at
gcc/config/mips/loongson-mmi.md:167
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: lin1.hu at intel dot com
Target Milestone: ---
If I understand correctly. mips's packuswh(vec_pack_usat_<mode>) means convert
signed integer to unsigned integer with unsigned saturation. But gcc's
us_saturate means unsigned integer convert unsigned integer with unsigned
saturation. So the pattern should use UNSPEC.
