Bug ID: 118836
Summary: sso warning dependend on -fno-builtin
Product: gcc
Version: 14.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: george.thopas at gmail dot com
Target Milestone: ---
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100920 introduced some logic
to suppress scalar-storage-order warnings when using memcpy/memset/...
However when required to compile with -fno-builtin this won't work and will
still gives scalar-storage-order warnings
Thank you.
example : compiling gcc/testsuite/ gcc.dg/sso-14.c
bash$ gcc -Wall -fno-builtin sso-14.c
