From 39ddfef9a5c24acf6412236f52f6716c8e0ebc9e Mon Sep 17 00:00:00 2001 From: Hans-Peter Nilsson Date: Mon, 27 Jul 2020 00:08:54 +0200 Subject: [PATCH] mmix: Don't turn off .hidden support. In 2012 e2769e908a915ebbc/r192344, I added the following lines, that I now delete. I've changed my mind: ELF-related targets based on gas, that support only static linking, have .hidden "for free", regardless of the visibility of the hidden object in the linked executable. No regressions for mmix-knuth-mmixware and "fixes": FAIL: gcc.dg/torture/pr94947-1.c -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects (test for excess errors) Excess errors: lto1: warning: visibility attribute not supported in this configuration; ignored [-Wattributes] ...a warning which is emitted for "all" LTO tests (of which most have warnings filtered out); LTO "thinks" all supported targets have .hidden support. gcc: * configure.ac (out-of-tree linker .hidden support): Don't turn off for mmix-knuth-mmixware. * configure: Regenerate. --- gcc/configure | 6 ------ gcc/configure.ac | 6 ------ 2 files changed, 12 deletions(-) diff --git a/gcc/configure b/gcc/configure index f224679..5c31c13 100755 --- a/gcc/configure +++ b/gcc/configure @@ -23471,12 +23471,6 @@ else if test x"$ld_is_gold" = xyes; then : elif echo "$ld_ver" | grep GNU > /dev/null; then - case "${target}" in - mmix-knuth-mmixware) - # The linker emits by default mmo, not ELF, so "no" is appropriate. - gcc_cv_ld_hidden=no - ;; - esac if test 0"$ld_date" -lt 20020404; then if test -n "$ld_date"; then # If there was date string, but was earlier than 2002-04-04, fail diff --git a/gcc/configure.ac b/gcc/configure.ac index e83f083..a7c683b 100644 --- a/gcc/configure.ac +++ b/gcc/configure.ac @@ -2874,12 +2874,6 @@ else if test x"$ld_is_gold" = xyes; then : elif echo "$ld_ver" | grep GNU > /dev/null; then - case "${target}" in - mmix-knuth-mmixware) - # The linker emits by default mmo, not ELF, so "no" is appropriate. - gcc_cv_ld_hidden=no - ;; - esac if test 0"$ld_date" -lt 20020404; then if test -n "$ld_date"; then # If there was date string, but was earlier than 2002-04-04, fail -- 2.7.4
