Fix aarch64-linux-hw-point.c build problem
Due to a recent glibc header file change, the file
nat/aarch64-linux-hw-point.c no longer builds on Fedora rawhide.
An enum for PTRACE_SYSEMU is now provided by <sys/ptrace.h>. In the
past, PTRACE_SYSEMU was defined only in <asm/ptrace.h>. This is
what it looks like...
In <asm/ptrace.h>:
#define PTRACE_SYSEMU 31
In <sys/ptrace.h>:
enum __ptrace_request
{
...
PTRACE_SYSEMU = 31,
#define PT_SYSEMU PTRACE_SYSEMU
...
}
When <asm/ptrace.h> and <sys/ptrace.h> are both included in a source
file, we run into the following build problem when the former is
included before the latter:
In file included from nat/aarch64-linux-hw-point.c:26:
/usr/include/sys/ptrace.h:86:3: error: expected identifier before numeric constant
86 | PTRACE_SYSEMU = 31,
| ^~~~~~~~~~~~~
(There are more errors after this one too.)
The file builds without error when <asm/ptrace.h> is included after
<sys/ptrace.h>. I found that this is already done in
nat/aarch64-sve-linux-ptrace.h (which is included by
nat/aarch64-linux-ptrace.c).
I've tested this change on Fedora rawhide and Fedora 33, both
running on an aarch64 machine.
gdb/ChangeLog:
* nat/aarch64-linux-hw-point.c: Include <asm/ptrace.h> after
<sys/ptrace.h>.
