From ff220d4010717f7bfbbc02a2400666fb9d24f250 Mon Sep 17 00:00:00 2001 From: Darren Tucker Date: Tue, 21 Nov 2023 14:04:34 +1100 Subject: Stop using -fzero-call-used-regs=all ... since it seems to be problematic with several different versions of clang. Only use -fzero-call-used-regs=used which is less problematic, except with Apple's clang where we don't use it at all. bz#3629, ok djm@ --- configure.ac | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'configure.ac') diff --git a/configure.ac b/configure.ac index 92540d03..36e1028e 100644 --- a/configure.ac +++ b/configure.ac @@ -231,9 +231,12 @@ if test "$GCC" = "yes" || test "$GCC" = "egcs"; then # clang 15 seems to have a bug in -fzero-call-used-regs=all.
