gold: x86-64: Fix TLSDESC -> LE relaxation X86-64 TLSDESC sequences can be: 4c 8d 0d 00 00 00 00 leaq foo@TLSDESC(%rip), %r9 4c 89 c8 movq %r9, %rax ff 10 call foo@TLSCALL(%rax) TLSDESC -> LE relaxation can turn them into: 49 c7 c1 fc ff ff ff mov $0xfffffffffffffffc,%r9 4c 89 c8 mov %r9,%rax 66 90 xchg %ax,%ax We need to check and update the REX byte in this case. PR gold/25473 x86_64.cc (Target_x86_64<size>::Relocate::tls_desc_gd_to_ie): Properly check r8 - r15 in "lea foo@TLSDESC(%rip), %reg". (Target_x86_64<size>::Relocate::tls_desc_gd_to_le): Properly relax r8 - r15 in "lea foo@TLSDESC(%rip), %reg". * testsuite/Makefile.am (check_SCRIPTS): Add x86_64_gd_to_le.sh.
