Subject: [PATCH] bits/siginfo.h: enum definition for TRAP_HWBKPT is missing

Compile following linux kernel test code with latest glibc:
|
||||
|
||||
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/testing/selftests/breakpoints/breakpoint_test_arm64.c
|
||||
|
||||
and we get following error:
|
||||
breakpoint_test_arm64.c: In function ‘run_test’:
|
||||
breakpoint_test_arm64.c:171:25: error: ‘TRAP_HWBKPT’ undeclared (first use in this function)
|
||||
if (siginfo.si_code != TRAP_HWBKPT) {
|
||||
^
|
||||
I can compile test code by modifying my local
|
||||
/usr/include/bits/siginfo.h and test works great. Therefore, this patch
|
||||
will be needed in upstream glibc so that issue is fixed there as well.
