-Subject: [PATCH] PR gdb/33747: gdb/ser-unix: modernize Linux
custom baud rate
- support
-
-The Linux custom baud rate implementation previously accessed the
-struct termios members c_ispeed and c_ospeed directly. These fields
-exist in glibc but are not exposed by musl, causing builds to fail on
-musl-based systems.
-
-Update set_custom_baudrate_linux to use a capability-based approach,
-with three distinct code paths:
-
-1) If POSIX cfsetispeed/cfsetospeed accept arbitrary baud rates
- (HAVE_CFSETSPEED_ARBITRARY), use them to set input and output
- speeds.
-
-2) Else if Linux termios2 interface is available (TCGETS2/BOTHER),
- use it to support arbitrary baud rates.
-
-3) Else if legacy struct termios supports c_ispeed/c_ospeed, use
- the TCGETS/TCSETS fallback (primarily for glibc on older
- architectures).
-
-4) Otherwise, emit an error indicating that custom baud rates are
- unsupported on this platform.
-
-This preserves existing behavior on glibc systems while restoring
-build compatibility with musl and other libc implementations.

-Subject: [PATCH] GDB: aarch64-linux: Fix build failure on musl
systems
-
-(cherry picked from commit 02090062127d59978ccc312dabf63c6ea838cd85)
-
-When building against musl (e.g. on Alpine Linux), the following
error
-happens:

-
-aarch64-linux-tdep.c fails to build in the same way. This happens
because
-aarch64-gcs-linux.h uses GCS_MAGIC to see whether the system headers
-have GCS-related definitions. The problem is that GCS_MAGIC is
defined in
-<asm/sigcontext.h> while struct gcs_user is defined in
<asm/ptrace.h>.
-It's fine on glibc systems because in the set of system headers that
-linux-aarch64-low.cc
<https://urldefense.com/v3/__http://-linux-aarch64-low.cc__;!!AjveYdw8EvQ!fyAFzcZAS5SwW5I3koSFwppdXq6v4bUcjuz1Tas5CXmG1n3w5-FLW9Lt_yxEAi5CePPVtiY5U9MftNMOnk1_cOqLx6yxF3rpGw$>
and aarch64-linux-tdep.c include, <asm/sigcontext.h>
-ends up being included implicitly as well. This doesn't happen
when using
-musl's headers though.
-
-There isn't a macro in <asm/ptrace.h> whose presence is
correlated with
-the presence of the struct user_gcs definition, so a configure
check is
-needed to detect it and conditionally define the struct.
-
-Also, this change requires aarch64-linux-tdep.c to stop using
-struct user_gcs because target-dependent code can't include
<asm/ptrace.h>
-and thus even if HAVE_STRUCT_USER_GCS is set, the file won't have the
-struct definition available. To fix this problem, also backport the
-definition of AARCH64_LINUX_SIZEOF_GCS_REGSET and use it there.
-
-Note that there's another build issue with musl, described in
-PR gdb/33747 affecting compilation of gdb/ser-unix.c. In order to be
-able to test this patch, I applied the patch in comment 11 there.
-
-Tested with a native build on an Alpine Linux aarch64 system, and
also
-verified that all gdb.arch/aarch64-gcs*.exp tests pass on it.
