Bug ID: 104208
Summary: -mlong-double-64 should override a previous
-mabi=ibmlongdouble
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: fw at gcc dot gnu.org
Target Milestone: ---
Build: powerpc64le-*-linux-gnu
We have trouble building glibc 2.35 with GCC 12 because -mlong-double-64 and
-mabi=ibmlongdouble conflict:
ppc64le: gcc 12 vs -mabi=ibmlongdouble
https://sourceware.org/pipermail/libc-alpha/2022-January/135647.html
glibc needs to build itself with -mabi=ibmlongdouble because that's how the
source tree defaults are laid out, and given our build system, it's very
difficult to remove that for individual files. So I'd appreciate a GCC-side fix
for this.
