From: Thomas Huth <th...@redhat.com> This reverts commit 2d6d995709482cc8b6a76dbb5334a28001a14a9a.
OpenBSD 7.7 fixed the problem with the -fzero-call-used-regs on OpenBSD, see https://github.com/openbsd/src/commit/03eca72d1e030b7a542cd6aec1 for the fix there. Suggested-by: Brad Smith <b...@comstyle.com> Signed-off-by: Thomas Huth <th...@redhat.com> --- Note: Marked as RFC since we likely can include this only once OpenBSD 7.6 goes out of service, see: https://lists.libreplanet.org/archive/html/qemu-arm/2025-05/msg00559.html meson.build | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/meson.build b/meson.build index 6c61e1dcaec..5f0e6a65cb0 100644 --- a/meson.build +++ b/meson.build @@ -699,11 +699,7 @@ hardening_flags = [ # # NB: Clang 17 is broken and SEGVs # https://github.com/llvm/llvm-project/issues/75168 -# -# NB2: This clashes with the "retguard" extension of OpenBSD's Clang -# https://gitlab.com/qemu-project/qemu/-/issues/2278 -if host_os != 'openbsd' and \ - cc.compiles('extern struct { void (*cb)(void); } s; void f(void) { s.cb(); }', +if cc.compiles('extern struct { void (*cb)(void); } s; void f(void) { s.cb(); }', name: '-fzero-call-used-regs=used-gpr', args: ['-O2', '-fzero-call-used-regs=used-gpr']) hardening_flags += '-fzero-call-used-regs=used-gpr' -- 2.49.0
