Bug ID: 115978
Summary: x86 backend crashes when using -m32 -march=native (if
machine support APX)
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: lingling.kong7 at gmail dot com
Target Milestone: ---
Target: x86-64
Now x86 backend crashes when using `-m32 -mapxf`
(https://godbolt.org/z/zar7aPen3) because we need to let them know there's a
conflict by reporting an error, otherwise it may breaks their expectation.
But user may try to enable all the possible feature in 32-bit mode on current
machine when passing "-march=native -m32".User does not need to know the
feature dependencies.
Proposal is to add the doc in the help info of -m32 instead of report error to
improve {-m32 -march=native} compilation capabilities.
