-Subject: [PATCH] x86: Fix -fsplit-stack feature detection via
- TARGET_CAN_SPLIT_STACK
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Since commit c163647ffbc9a20c8feb6e079dbecccfe016c82e -fsplit-stack
-is only supported on glibc targets. However, this original commit
-required some fixups. As part of the fixup, the changes to the
-gnu-user-common.h and gnu.h where partially reverted in commit
-60953a23d57b13a672f751bec0c6eefc059eb1ab thus causing TARGET_CAN_SPLIT_STACK
-to be defined for non-glibc targets even though -fsplit-stack is
-actually not supported and attempting to use it causes a runtime error.
-
-This causes gcc internal code, such as ./gcc/go/gospec.c to not
-correctly detect that -fsplit-stack is not supported and thus causes
-gccgo to fail compilation on non-glibc targets.
-
-This commit ensures that TARGET_CAN_SPLIT_STACK is set based on the
-changes performed in 2c31a8be4a5db11a0a0e97c366dded6362421086, i.e.
-the new OPTION_GLIBC_P macro is now used to detect if -fsplit-stack is
-supported in the x86 header files.
-
-The proposed changes have been tested on x86_64 Alpine Linux (which uses
-musl libc) and fix compilation of gccgo for this target.

-gcc/ChangeLog:
-
- * config/i386/gnu-user-common.h (defined): Only define
- TARGET_CAN_SPLIT_STACK for glibc targets.
- * config/i386/gnu.h (defined): Ditto.
