From 3d5ecb624638627869e6965410f558b15db6946e Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 26 Oct 2021 09:02:57 -0300 Subject: Fix LIBC_PROG_BINUTILS for -fuse-ld=lld GCC does not print the correct linker when -fuse-ld=lld is used with the -print-prog-name=ld: $ gcc -v 2>&1 | tail -n 1 gcc version 11.2.0 (Ubuntu 11.2.0-7ubuntu2) $ gcc ld This is different than for gold: $ gcc -fuse-ld=gold -print-prog-name=ld ld.gold Using ld.lld as the static linker name prints the expected result. This is only required when -fuse-ld=lld is used, if lld is used as the 'ld' programs (through a symlink) LIBC_PROG_BINUTILS works as expected. Checked on x86_64-linux-gnu.
