Bug ID: 112330
Summary: [14 Regression] LoongArch: LTO bootstrap failure with
GAS 2.41
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: xry111 at gcc dot gnu.org
Target Milestone: ---
r14-5053 fails to LTO bootstrap with GAS 2.41 and the following configuration:
../gcc/configure --prefix=/home/xry111/gcc-dev --with-system-zlib
--disable-fixincludes --enable-default-ssp --enable-default-pie
--disable-werror --disable-multilib --with-build-config=bootstrap-lto && make
-j32
The error message is:
/usr/bin/as: /usr/bin/as: BFD (Gentoo 2.41 p2) 2.41.0 internal error, aborting
at /tmp/portage/sys-devel/binutils-2.41-r2/work/binutils-2.41/bfd/bfd.c:1185 in
_bfd_doprnt
/usr/bin/as: Please report this bug.
The problem is since r14-4674 we are relying on Binutils commit
1fb3cdd87ec61715a5684925fb6d6a6cf53bb97c, which is not available in GAS 2.41.
I guess the easiest solution is raising the minimal GAS requirement of
bootstrapping GCC 14 on LoongArch to 2.42.
