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.
