Hi,
In Fedora crash.spec, currently the LTO is disabled as below:
+# This package has an internal copy of GDB which has broken configure code for
+# INTDIV0_RAISES_SIGFPE and MUST_REINSTALL_SIGHANDLERS
+# Updating that code properly seems nontrivial and best left to the package
+# maintainer.
+# Disable LTO
+%define _lto_cflags %{nil}
+# INTDIV0_RAISES_SIGFPE and MUST_REINSTALL_SIGHANDLERS
+# Updating that code properly seems nontrivial and best left to the package
+# maintainer.
+# Disable LTO
+%define _lto_cflags %{nil}
commit: c6fc69dae3a2 ("Disable LTO")
In RHEL9, that(disable LTO) was inherited from Fedora. But, currently a bug is reported to enable the LTO build for RHEL9:
I tried to remove the macro "%define _lto_cflags %{nil}" from the crash.spec, and then build the rpm packages, But I didn't see the lto flag such as "-flto" or "-ffat-lto-objects" during the whole build stage, and the build process passed without any error reports.
I'm wondering if it could rely on the redhat-rpm-config macro or it(LTO flag) can take effect when the toolchain is clang(not gcc)? Any thoughts?
Thanks.
Lianbo
