package/gdb: add support for gdb 11.x
All patch from gdb 10.2 are kept. Starting from version 11.x, gdb needs the gmp library. The target variant needs a bit of care: if BR2_GDB_VERSION_11 is not set, either the host gdb is not enabled, in which case the default for the target gdb is 9.x, or the host gdb is enabled, and another version is selected. Signed-off-by: Michael Fischer <mf@go-sys.de> [Thomas: - fix how the gmp dependency is handled - set BR2_PACKAGE_GDB_TOPLEVEL to y for gdb 11.x - fix how BR2_GDB_VERSION is set for gdb 11.x] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> [yann.morin.1998@free.fr: - only select target gmp if using gdb 11 ] Signed-off-by: Yann E. MORIN <yann.morin.1998@free.fr>

Build fix for MIPS with musl libc
|

|
||||
The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
|
||||
but not by musl. Regardless of the libc, the kernel headers provide
|
||||
<asm/sgidefs.h> which provides the same definitions, so use that
|
||||
instead.

As for strace [1], when <sys/reg.h> is included after <linux/ptrace.h>,
|
||||
the build fails on m68k with the following diagnostics:
|
||||
|
||||
In file included from ./../nat/linux-ptrace.h:28:0,
|
||||
from linux-low.h:27,
|
||||
from linux-m68k-low.c:20:

[...]usr/include/sys/reg.h:99:1: error: expected declaration before « } » token
|
||||
};
|
||||
^
|
||||
|
||||
Fix this by moving <sys/reg.h> on top of "linux-low.h".

Subject: [PATCH] nat/fork-inferior: include linux-ptrace.h
|
||||
|
||||
To decide whether fork() or vfork() should be used, fork-inferior.c
|
||||
uses the following test:
|
||||
|
||||
#if !(defined(__UCLIBC__) && defined(HAS_NOMMU))
|
||||
|
||||
However, HAS_NOMMU is never defined, because it gets defined in
|
||||
linux-ptrace.h, which is not included by fork-inferior.c. Due to this,
|
||||
gdbserver fails to build on noMMU architectures. This commit fixes
|
||||
that by simply including linux-ptrace.h.
|
||||
|
||||
This bug was introduced by commit
|
||||
2090129c36c7e582943b7d300968d19b46160d84 ("Share fork_inferior et al
|
||||
with gdbserver"). Indeed, the same fork()/vfork() selection was done,
|
||||
but in another file where linux-ptrace.h was included.
|
||||
|
||||
Fixes the following build issue:
|
||||
|
||||
../nat/fork-inferior.c: In function 'pid_t fork_inferior(const char*, const string&, char**, void (*)(), void (*)(int), void (*)(), const char*, void (*)(const char*, char* const*, char* const*))':
|
||||
../nat/fork-inferior.c:376:11: error: 'fork' was not declared in this scope
|
||||
pid = fork ();
|
||||
^~~~
|
||||
../nat/fork-inferior.c:376:11: note: suggested alternative: 'vfork'
|
||||
pid = fork ();
