>From 18fbfe3d757372fc904146a9156e8af466c9f013 Mon Sep 17 00:00:00 2001 From: Peter Waller <peter.wal...@arm.com> Date: Thu, 25 Jan 2024 14:29:45 +0000 Subject: [PATCH] [AArch64][compiler-rt] Avoid use of libc header in sme-libc-routines The use of `#include <stdlib.h>` introduces a libc dependency. In many build environments such a file can be found under e.g. /usr/include, but this does not correspond to the libc in use, which may not be available until after the builtins have been built. So far as I understand, it's not valid to have a dependency on libc from builtins; there are a handful of such includes in builtins, but they are protected by ifdefs. Instead, use <stddef.h> which is provided by the compiler's resource headers and so should always be available. --- compiler-rt/lib/builtins/aarch64/sme-libc-routines.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/compiler-rt/lib/builtins/aarch64/sme-libc-routines.c b/compiler-rt/lib/builtins/aarch64/sme-libc-routines.c index cd73025a19cc1ac..89b52b0d1a8805c 100644 --- a/compiler-rt/lib/builtins/aarch64/sme-libc-routines.c +++ b/compiler-rt/lib/builtins/aarch64/sme-libc-routines.c @@ -1,4 +1,4 @@ -#include <stdlib.h> +#include <stddef.h> // WARNING: When building the scalar versions of these functions you need to // use the compiler flag "-mllvm -disable-loop-idiom-all" to prevent clang _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
