package/gdb: add version 8.1
https://sourceware.org/ml/gdb-announce/2018/msg00001.html gdb 8.1 has a new optional dependency on mpfr, which according to the NEWS file: GDB now uses the GNU MPFR library, if available, to emulate target floating-point arithmetic during expression evaluation when the target uses different floating-point formats than the host. At least version 3.1 of GNU MPFR is required. So for the target gdb, this is unnecessary, and therefore we forcefully disable mpfr support by passing --without-mpfr. For the host gdb, it would potentially be useful, but since it's a new feature that isn't essential, we for now keep it disabled as well. An option may be added later if needed. To avoid gnulib issues with uClibc/musl, we need to pass additional configure/make variables, like is done in OpenEmbedded [1]. [1] http://git.openembedded.org/openembedded-core/tree/meta/recipes-devtools/gdb/gdb_8.1.bb?id=02664a8dcd1ebb6cd77248e1b97a78390ea06033#n9 We re-add the same patches as the ones present for gdb 8.0.1, except 0004-nat-linux-ptrace.c-add-missing-gdb_byte-cast.patch, which was merged upstream.

Subject: [PATCH] use <asm/sgidefs.h>
|

|

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:26:3: error: expected identifier before numeric constant
|
||||
PT_D1 = 0,
|
||||
^
|
||||
[...]usr/include/sys/reg.h:26:3: error: expected « } » before numeric constant
|
||||
[...]usr/include/sys/reg.h:26:3: error: expected unqualified-id before numeric constant
|
||||
In file included from linux-m68k-low.c:27:0:
|
||||
[...]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".
