This patch allows using gcc-go with libucontext. For this purpose,
it unconditionally links gcc-go against -lucontext. Furthermore,
it undefines SETCONTEXT_CLOBBERS_TLS in proc.c to prevent usage
of makecontext/swapcontext feature that are not support by libucontext.

Subject: [PATCH] libgo: Recognize off64_t and loff_t definitions of musl libc
From 3b9243b891cc06373639a23ed5717b0d1c2d8ea6 Mon Sep 17 00:00:00 2001
From: Ian Lance Taylor <iant@golang.org>

Subject: [PATCH] libgo: permit loff_t and off_t to be macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Without this patch, both off64_t and loff_t are not recognized by
-fdump-go-spec which causes a variety Go-related compilation errors on
musl libc since the gcc-go frontend expects both off64_t and loff_t to
be present.
They are macros in musl libc, rather than typedefs, and -fgo-dump-spec
doesn't handle that case.
Also make sure that autoconf recognizes support for loff_t on musl, by
compiling the relevant feature test code with -D_GNU_SOURCE and making
it include fcntl.h which defines loff_t on musl.
Based on patch by Sören Tempel.

Subject: [PATCH] libgo: use _off_t for mmap offset argument
Without this patch, Go run-time memory allocation fails on 32-bit architectures:
On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
64-bit type on 64-bit systems by default. However, on systems using musl
libc off_t is unconditionally a 64-bit type. As such, it is insufficient
to use a uintptr type for the mmap offset parameter.

[1]: https://git.adelielinux.org/adelie/packages/-/commit/63b5fb12c3d75e460799c672bbbdd5d29c3cc33c
Presently, the (incorrect) mmap declaration causes a libgo run-time
failure on 32-bit musl systems (fatal error: runtime: cannot allocate
memory). This commit fixes this run-time error.

Subject: [PATCH] libgo: include asm/ptrace.h for pt_regs definition on PowerPC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Both glibc and musl libc declare pt_regs as an incomplete type. This
type has to be completed by inclusion of another header. On Linux, the
asm/ptrace.h header file provides this type definition. Without
including this header file, it is not possible to access the regs member
of the mcontext_t struct as done in libgo/runtime/go-signal.c. On glibc,
other headers (e.g. sys/user.h) include asm/ptrace.h but on musl
asm/ptrace.h is not included by other headers and thus the
aforementioned files do not compile without an explicit include of
asm/ptrace.h:
libgo/runtime/go-signal.c: In function 'getSiginfo':
libgo/runtime/go-signal.c:227:63: error: invalid use of undefined type 'struct pt_regs'
227 | ret.sigpc = ((ucontext_t*)(context))->uc_mcontext.regs->nip;
|
Instead of including the asm/ptrace.h header conditionally on PowerPC
only it would alternatively also be possible to include it
unconditionally.

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
for some reason, TARGET_CAN_SPLIT_STACK still gets defined on 32-bit x86,
so hackfix it for now
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 were 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 only set if the
default libc is glibc. It is presently unclear to me if there is a
better way to detect glibc at pre-processor time.
The proposed changes have been tested on x86 and 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.

_sigev_un on glibc. Not sure what this code actually does and
how this works if the union layout is different…
Previously, libgo relied on the _sigev_un implementation-specific
field in struct sigevent, which is only available on glibc.
This patch uses the sigev_notify_thread_id macro instead which is
mandated by timer_create(2). In theory, this should work with any libc
implementation for Linux. Unfortunately, there is an open glibc bug
as glibc does not define this macro. For this reason, a glibc-specific
workaround is required. Other libcs (such as musl) define the macro
and don't require the workaround.
See https://sourceware.org/bugzilla/show_bug.cgi?id=27417
This makes libgo compatible with musl libc.
Based on patch by Sören Tempel.

Subject: [PATCH] libgo: use SYS_timer_settime32
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On 32-bit systems musl only defines SYS_timer_settime32 not
SYS_timer_settime. This causes the following compilation error:
Musl defines SYS_timer_settime32, not SYS_timer_settime, on 32-bit systems.
os_linux.go:251:30: error: reference to undefined name '_SYS_timer_settime'
251 | return int32(syscall(_SYS_timer_settime, uintptr(timerid), uintptr(flags), uintptr(unsafe.Pointer(new)), uintptr(unsafe.Pointer(old)), 0, 0))
| ^
Based on patch by Sören Tempel.
This commit fixes this error by defining SYS_timer_settime to
SYS_timer_settime32 if the latter is defined.

Subject: [PATCH] libgo: use POSIX shell arithmetic expansion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The `(( expression ))` syntax is a Bash extension. However, the
arithmetic expressions used by the gobuild() function can also
be expressed using Arithmetic POSIX Expansion with `$(( expression ))`.
Contrary to the Bash expression, the Arithmetic Expansion doesn't set
the return value if the expression is non-zero but instead just prints
the expression result. Hence, the expression also needs to be negated.
Avoid bash-specific ((expression)) syntax. As the bash syntax
converts a non-zero value to a zero status (and a zero value to a 1
status), and POSIX arithmetic expansion does not, we have to negate
the result.
Based on patch by Sören Tempel.

Subject: [PATCH] gcc-go: support libucontext
This patch allows using gcc-go with libucontext. For this purpose,
it unconditionally links gcc-go against -lucontext. Furthermore,
it undefines SETCONTEXT_CLOBBERS_TLS in proc.c to prevent usage
of makecontext/swapcontext feature that are not support by libucontext.

Subject: [PATCH] libgo: Recognize off64_t and loff_t definitions of musl libc
From 3b9243b891cc06373639a23ed5717b0d1c2d8ea6 Mon Sep 17 00:00:00 2001
From: Ian Lance Taylor <iant@golang.org>
Date: Tue, 14 Jun 2022 06:13:43 -0700
Subject: [PATCH] libgo: permit loff_t and off_t to be macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Without this patch, both off64_t and loff_t are not recognized by
-fdump-go-spec which causes a variety Go-related compilation errors on
musl libc since the gcc-go frontend expects both off64_t and loff_t to
be present.
They are macros in musl libc, rather than typedefs, and -fgo-dump-spec
doesn't handle that case.
Also make sure that autoconf recognizes support for loff_t on musl, by
compiling the relevant feature test code with -D_GNU_SOURCE and making
it include fcntl.h which defines loff_t on musl.
Based on patch by Sören Tempel.

Subject: [PATCH] libgo: use _off_t for mmap offset argument
Without this patch, Go run-time memory allocation fails on 32-bit architectures:
On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
64-bit type on 64-bit systems by default. However, on systems using musl
libc off_t is unconditionally a 64-bit type. As such, it is insufficient
to use a uintptr type for the mmap offset parameter.

Presently, the (incorrect) mmap declaration causes a libgo run-time
failure on 32-bit musl systems (fatal error: runtime: cannot allocate
memory). This commit fixes this run-time error.

Subject: [PATCH] libgo: include asm/ptrace.h for pt_regs definition on PowerPC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Both glibc and musl libc declare pt_regs as an incomplete type. This
type has to be completed by inclusion of another header. On Linux, the
asm/ptrace.h header file provides this type definition. Without
including this header file, it is not possible to access the regs member
of the mcontext_t struct as done in libgo/runtime/go-signal.c. On glibc,
other headers (e.g. sys/user.h) include asm/ptrace.h but on musl
asm/ptrace.h is not included by other headers and thus the
aforementioned files do not compile without an explicit include of
asm/ptrace.h:
libgo/runtime/go-signal.c: In function 'getSiginfo':
libgo/runtime/go-signal.c:227:63: error: invalid use of undefined type 'struct pt_regs'
227 | ret.sigpc = ((ucontext_t*)(context))->uc_mcontext.regs->nip;
|
Instead of including the asm/ptrace.h header conditionally on PowerPC
only it would alternatively also be possible to include it
unconditionally.

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
for some reason, TARGET_CAN_SPLIT_STACK still gets defined on 32-bit x86,
so hackfix it for now
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 were 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 only set if the
default libc is glibc. It is presently unclear to me if there is a
better way to detect glibc at pre-processor time.
The proposed changes have been tested on x86 and 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.

Subject: [PATCH] jit: avoid calloc() poisoning on musl [PR106102]
On musl <pthread.h> uses calloc() (via <sched.h>). jit/ includes
it directly and exposes use of poisoned calloc():

Subject: [PATCH] runtime: portable access to sigev_notify_thread_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The union in struct sigevent is named __sev_fields on musl but
_sigev_un on glibc. Not sure what this code actually does and
how this works if the union layout is different…
Previously, libgo relied on the _sigev_un implementation-specific
field in struct sigevent, which is only available on glibc.
This patch uses the sigev_notify_thread_id macro instead which is
mandated by timer_create(2). In theory, this should work with any libc
implementation for Linux. Unfortunately, there is an open glibc bug
as glibc does not define this macro. For this reason, a glibc-specific
workaround is required. Other libcs (such as musl) define the macro
and don't require the workaround.
See https://sourceware.org/bugzilla/show_bug.cgi?id=27417
This makes libgo compatible with musl libc.
Based on patch by Sören Tempel.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On 32-bit systems musl only defines SYS_timer_settime32 not
SYS_timer_settime. This causes the following compilation error:
Musl defines SYS_timer_settime32, not SYS_timer_settime, on 32-bit systems.

Based on patch by Sören Tempel.
This commit fixes this error by defining SYS_timer_settime to
SYS_timer_settime32 if the latter is defined.

Subject: [PATCH] libgo: use POSIX shell arithmetic expansion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The `(( expression ))` syntax is a Bash extension. However, the
arithmetic expressions used by the gobuild() function can also
be expressed using Arithmetic POSIX Expansion with `$(( expression ))`.
Contrary to the Bash expression, the Arithmetic Expansion doesn't set
the return value if the expression is non-zero but instead just prints
the expression result. Hence, the expression also needs to be negated.
Avoid bash-specific ((expression)) syntax. As the bash syntax
converts a non-zero value to a zero status (and a zero value to a 1
status), and POSIX arithmetic expansion does not, we have to negate
the result.
Based on patch by Sören Tempel.

Subject: [PATCH] gcc-go: support libucontext
This patch allows using gcc-go with libucontext. For this purpose,
it unconditionally links gcc-go against -lucontext. Furthermore,
it undefines SETCONTEXT_CLOBBERS_TLS in proc.c to prevent usage
of makecontext/swapcontext feature that are not support by libucontext.

Subject: [PATCH] libgo: permit loff_t and off_t to be macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Without this patch, both off64_t and loff_t are not recognized by
-fdump-go-spec which causes a variety Go-related compilation errors on
musl libc since the gcc-go frontend expects both off64_t and loff_t to
be present.
They are macros in musl libc, rather than typedefs, and -fgo-dump-spec
doesn't handle that case.
Also make sure that autoconf recognizes support for loff_t on musl, by
compiling the relevant feature test code with -D_GNU_SOURCE and making
it include fcntl.h which defines loff_t on musl.
Based on patch by Sören Tempel.

Subject: [PATCH] libgo: use _off_t for mmap offset argument
Without this patch, Go run-time memory allocation fails on 32-bit architectures:
On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
64-bit type on 64-bit systems by default. However, on systems using musl
libc off_t is unconditionally a 64-bit type. As such, it is insufficient
to use a uintptr type for the mmap offset parameter.

Presently, the (incorrect) mmap declaration causes a libgo run-time
failure on 32-bit musl systems (fatal error: runtime: cannot allocate
memory). This commit fixes this run-time error.

Subject: [PATCH] libgo: include asm/ptrace.h for pt_regs definition on PowerPC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Both glibc and musl libc declare pt_regs as an incomplete type. This
type has to be completed by inclusion of another header. On Linux, the
asm/ptrace.h header file provides this type definition. Without
including this header file, it is not possible to access the regs member
of the mcontext_t struct as done in libgo/runtime/go-signal.c. On glibc,
other headers (e.g. sys/user.h) include asm/ptrace.h but on musl
asm/ptrace.h is not included by other headers and thus the
aforementioned files do not compile without an explicit include of
asm/ptrace.h:
libgo/runtime/go-signal.c: In function 'getSiginfo':
libgo/runtime/go-signal.c:227:63: error: invalid use of undefined type 'struct pt_regs'
227 | ret.sigpc = ((ucontext_t*)(context))->uc_mcontext.regs->nip;
|
Instead of including the asm/ptrace.h header conditionally on PowerPC
only it would alternatively also be possible to include it
unconditionally.

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
for some reason, TARGET_CAN_SPLIT_STACK still gets defined on 32-bit x86,
so hackfix it for now
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 were 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 only set if the
default libc is glibc. It is presently unclear to me if there is a
better way to detect glibc at pre-processor time.
The proposed changes have been tested on x86 and 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] runtime: portable access to sigev_notify_thread_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The union in struct sigevent is named __sev_fields on musl but
_sigev_un on glibc. Not sure what this code actually does and
how this works if the union layout is different…
Previously, libgo relied on the _sigev_un implementation-specific
field in struct sigevent, which is only available on glibc.
This patch uses the sigev_notify_thread_id macro instead which is
mandated by timer_create(2). In theory, this should work with any libc
implementation for Linux. Unfortunately, there is an open glibc bug
as glibc does not define this macro. For this reason, a glibc-specific
workaround is required. Other libcs (such as musl) define the macro
and don't require the workaround.
See https://sourceware.org/bugzilla/show_bug.cgi?id=27417
This makes libgo compatible with musl libc.
Based on patch by Sören Tempel.

On 32-bit systems musl only defines SYS_timer_settime32 not
SYS_timer_settime. This causes the following compilation error:
Musl defines SYS_timer_settime32, not SYS_timer_settime, on 32-bit systems.

Based on patch by Sören Tempel.
This commit fixes this error by defining SYS_timer_settime to
SYS_timer_settime32 if the latter is defined.

The `(( expression ))` syntax is a Bash extension. However, the
arithmetic expressions used by the gobuild() function can also
be expressed using Arithmetic POSIX Expansion with `$(( expression ))`.
Contrary to the Bash expression, the Arithmetic Expansion doesn't set
the return value if the expression is non-zero but instead just prints
the expression result. Hence, the expression also needs to be negated.
Avoid bash-specific ((expression)) syntax. As the bash syntax
converts a non-zero value to a zero status (and a zero value to a 1
status), and POSIX arithmetic expansion does not, we have to negate
the result.
Based on patch by Sören Tempel.
