Use __libc_ptf_call in _longjmp_unwind
Use __libc_ptf_call in _longjmp_unwind to avoid duplicated logic. On
x86-64, I got
jmp-unwind.os:
_longjmp_unwind:
movl __libc_pthread_functions_init(%rip), %eax
testl %eax, %eax
jne .L4
rep ret
.L4:
movq 304+__libc_pthread_functions(%rip), %rax
movq %rsp, %rsi
ror $2*8+1, %rax
xor %fs:48, %rax
jmp *%rax
jmp-unwind.o:
_longjmp_unwind:
movl $__pthread_cleanup_upto, %eax
testq %rax, %rax
je .L1
movq %rsp, %rsi
jmp __pthread_cleanup_upto
.L1:
rep ret
* sysdeps/nptl/jmp-unwind.c: Include <libc-lock.h> instead of
<nptl/pthreadP.h>.
(_longjmp_unwind): Use __libc_ptf_call.
* sysdeps/unix/sysv/linux/s390/jmp-unwind.c: Likewise.
