Subject: [PATCH] Disable -fsplit-stack support on non-glibc targets
The -fsplit-stack option requires the pthread_t TCB definition in the
libc to provide certain struct fields at specific hardcoded offsets. As
far as I know, only glibc provides these fields at the required offsets.
Most notably, musl libc does not have these fields. However, since gcc
accesses the fields using a fixed offset this does not cause a
compile-time error but instead results in a silent memory corruption at
run-time. For example, on s390x libgcc's __stack_split_initialize CTOR
will overwrite the cancel field in the pthread_t TCB on musl.
The -fsplit-stack option is used within the gcc code base by gcc-go by
default. On musl based systems with split-stack support (e.g. s390x or
x86) this causes Go programs compiled with gcc-go to misbehave at
run-time.
This patch fixes gcc-go on musl by disabling -fsplit-stack in gcc itself
since it is not supported on non-glibc targets anyhow. This is achieved
by checking if TARGET_GLIBC_MAJOR is defined to a non-zero value (it
defaults to zero on non-glibc systems). The check has been added for x86
and s390x, the rs6000 config already checks for TARGET_GLIBC_MAJOR. With
this patch applied, the gcc-go configure script will detect that
-fsplit-stack support is not available and will not use it.
This patch has been tested on Alpine Linux Edge on the s390x
architecture by bootstrapping Google's Go implementation with gcc-go.

offsets in the pthread_t TCB. The patch has been tested on Alpine Linux
Edge on the s390x and x86 architectures by bootstrapping Google's Go
implementation with gcc-go.

I bet instead of opts->x_linux_libc != LIBC_GLIBC it needs to use
#ifdef OPTION_GLIBC
if (!OPTION_GLIBC)
#endif
or so. I think the first committed patch actually used that
but used it in #if directive, which is wrong because it is something
that needs to be evaluated at runtime.
That doesn't work well either, because the *supports_split_stack
hooks have opts argument and OPTION_GLIBC doesn't take that.
So, here is a patch that introduces OPTION_*_P macros that take opts
as an argument and redefines OPTION_* using those (similarly to how
the option scripts create TARGET_*_P and TARGET_* macros).

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.
Signed-off-by: Sören Tempel <soeren@soeren-tempel.net>
gcc/ChangeLog:
* config/i386/gnu-user-common.h (defined): Only define
TARGET_CAN_SPLIT_STACK for glibc targets.
* config/i386/gnu.h (defined): Ditto.

Subject: [PATCH] Disable -fsplit-stack support on non-glibc targets
The -fsplit-stack option requires the pthread_t TCB definition in the
libc to provide certain struct fields at specific hardcoded offsets. As
far as I know, only glibc provides these fields at the required offsets.
Most notably, musl libc does not have these fields. However, since gcc
accesses the fields using a fixed offset this does not cause a
compile-time error but instead results in a silent memory corruption at
run-time. For example, on s390x libgcc's __stack_split_initialize CTOR
will overwrite the cancel field in the pthread_t TCB on musl.
The -fsplit-stack option is used within the gcc code base by gcc-go by
default. On musl based systems with split-stack support (e.g. s390x or
x86) this causes Go programs compiled with gcc-go to misbehave at
run-time.
This patch fixes gcc-go on musl by disabling -fsplit-stack in gcc itself
since it is not supported on non-glibc targets anyhow. This is achieved
by checking if TARGET_GLIBC_MAJOR is defined to a non-zero value (it
defaults to zero on non-glibc systems). The check has been added for x86
and s390x, the rs6000 config already checks for TARGET_GLIBC_MAJOR. With
this patch applied, the gcc-go configure script will detect that
-fsplit-stack support is not available and will not use it.
This patch has been tested on Alpine Linux Edge on the s390x
architecture by bootstrapping Google's Go implementation with gcc-go.

The -fsplit-stack option requires the pthread_t TCB definition in the
libc to provide certain struct fields at specific hardcoded offsets. As
far as I know, only glibc provides these fields at the required offsets.
Most notably, musl libc does not have these fields. However, since gcc

compile-time error, but instead results in a silent memory corruption at
run-time with musl libc. For example, on s390x libgcc's
__stack_split_initialize CTOR will overwrite the cancel field in the
pthread_t TCB on musl.
The -fsplit-stack option is used within the gcc code base itself by
gcc-go (if available). On musl-based systems with split-stack support
(i.e. s390x or x86) this causes Go programs compiled with gcc-go to
misbehave at run-time.
This patch fixes gcc-go on musl by disabling -fsplit-stack in gcc itself
since it is not supported on non-glibc targets anyhow. This is achieved
by checking if gcc targets a glibc-based system. This check has been
added for x86 and s390x, the rs6000 config already checks for
TARGET_GLIBC_MAJOR. Other architectures do not have split-stack
support. With this patch applied, the gcc-go configure script will
detect that -fsplit-stack support is not available and will not use it.
See https://www.openwall.com/lists/musl/2012/10/16/12
This patch was written under the assumption that glibc is the only libc
implementation which supports the required fields at the required
offsets in the pthread_t TCB. The patch has been tested on Alpine Linux
Edge on the s390x and x86 architectures by bootstrapping Google's Go
implementation with gcc-go.
