From aac5dfe6ddee33dbaef848160cef58a07f36ae86 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Thu, 10 Jun 2021 19:39:39 -0700 Subject: klibc: Add clang's -rtlib to known options This helps in ensuring that we always link klibc apps with libgcc as compiler-rt does not work for klibc due to missing libssp functions e.g. __stack_chk_guard and __stack_chk_guard which it expects in libc Signed-off-by: Khem Raj Cc: Andrea Adami --- .../klibc/files/klcc-cross-accept-clang-options.patch | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'meta-initramfs') diff --git a/meta-initramfs/recipes-devtools/klibc/files/klcc-cross-accept-clang-options.patch b/meta-initramfs/recipes-devtools/klibc/files/klcc-cross-accept-clang-options.patch index 56905a5159..431c75e3af 100644 --- a/meta-initramfs/recipes-devtools/klibc/files/klcc-cross-accept-clang-options.patch +++ b/meta-initramfs/recipes-devtools/klibc/files/klcc-cross-accept-clang-options.patch @@ -5,7 +5,7 @@ Signed-off-by: Khem Raj --- a/klcc/klcc.in +++ b/klcc/klcc.in -@@ -207,6 +207,24 @@ while ( defined($a = shift(@ARGV)) ) { +@@ -207,6 +207,27 @@ while ( defined($a = shift(@ARGV)) ) { } elsif ( $a =~ /^--([sysroot=])(.*)$/ ) { # Override gcc encoded sysroot push(@ccopt, $a); @@ -26,6 +26,9 @@ Signed-off-by: Khem Raj + push(@ccopt, $a); + } elsif ( $a =~ '--unwindlib=.*' ) { + # Allow clang options ++ push(@ccopt, $a); ++ } elsif ( $a =~ '-rtlib=.*' ) { ++ # Allow clang options + push(@ccopt, $a); } else { die "$0: unknown option: $a\n"; -- cgit 1.2.3-korg
