Bug ID: 121457
Summary: R_X86_64_CODE_6_GOTTPOFF configure test is broken with
binutils --enable-targets=all
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
CC: hjl.tools at gmail dot com
Target Milestone: ---
r14-9154-g7f2cf0c45f4ba7 adds a check for R_X86_64_CODE_6_GOTTPOFF support, but
it makes a bad assumption.
+ # Check if gas and gld support "addq %r23,foo@GOTTPOFF(%rip), %r15"
+ # with R_X86_64_CODE_6_GOTTPOFF relocation.
+ if echo "$ld_ver" | grep GNU > /dev/null; then
+ if $gcc_cv_ld -V 2>/dev/null | grep elf_x86_64_sol2 > /dev/null; then
+ ld_ix86_gld_64_opt="-melf_x86_64_sol2"
+ else
+ ld_ix86_gld_64_opt="-melf_x86_64"
+ fi
This will pass -melf_x86_64_sol2 on x86_64-pc-linux-gnu if binutils is built
with --enable-targets=all, and then gcc_cv_as_x86_64_code_6_gottpoff=no is set.
We should check first if $target is *solaris* (or something like that) and only
then have this fallback check.
