Folks, While developing the AArch64 port of glibc there were failures in nptl/tst-cancelx4.c and nptl/tst-cancelx5.c as follows: cleanup handler not called for 'open' cleanup handler not called for 'send' cleanup handler not called for 'recv' cleanup handler not called for 'pause' cleanup handler not called for 'select' The aarch64 port uses the ports/sysdeps/unix/sysv/linux/generic/ implementation of each of these functions. The aarch64 gcc compiler does not enable async unwind tables without explicit options. These five functions currently do not have explicit 'CFLAGS-xxxx.c = -fexception -fasync-unwind-tables' in the relevant libc Makefiles. The original aarch64 port submission attempted to fix the issue by adding CFLAGS-xxx= entries into the aarch64 specific Makefile, however I believe the solution should be generic rather than target specific. I'd appreciate feedback on the sanity of this solution. Patch attached, proposed ChangeLog below. Thanks /Marcus 2012-11-02 Marcus Shawcroft <marcus.shawcroft@linaro.org> * io/Makefile (CFLAGS-open.c, CFLAGS-open64.c): Define. * misc/Makefile (CFLAGS-select.c): Define. * nptl/Makefile (CFLAGS-open.c, CFLAGS-open64.c, CFLAGS-pause.c) (CFLAGS-recv.c, CFLAGS-send.c): Define. * posix/Makefile (CFLAGS-pause.c): Define.
