Bug ID: 118333
Summary: gcc/config/i386/i386-expand.cc:24871: Pointless
condition ?
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Static analyser cppcheck says:
gcc/config/i386/i386-expand.cc:24871:35: warning: Identical condition
'!TARGET_AVX512BW', second condition is always false
[identicalConditionAfterEarlyExit]
Source code is
if (!TARGET_AVX512BW)
return false;
if ((qimode == V16QImode && !TARGET_AVX2)
|| (qimode == V32QImode && (!TARGET_AVX512BW || !TARGET_EVEX512))
/* There are no V64HImode instructions. */
|| qimode == V64QImode)
return false;
Suggest remove second condition.
