From 7d48b7adadcd717a1da26a1b1def98601d767099 Mon Sep 17 00:00:00 2001 From: Thomas Schwinge Date: Thu, 9 May 2019 11:51:59 +0200 Subject: [PR89221] Continue to default to '--disable-frame-pointer' for x86 GNU systems The recent trunk r270914 for PR89221 "--enable-frame-pointer does not work as intended" fixed a scripting defect in the x86 '--enable-frame-pointer' handling. This has the side effect that, for example, for '--target=i686-gnu' this is now enabled by default: 'USE_IX86_FRAME_POINTER=1' is added to 'tm_defines'. Given that it's highly unlikely that anyone would now suddenly want '--enable-frame-pointer' as the default for any kind of GNU system, I'm changing the default back for GNU systems, to match that of a 'target_os' of 'linux* | darwin[8912]*'. gcc/ PR target/89221 * configure.ac (--enable-frame-pointer): Disable by default for GNU systems. * configure: Regenerate.
