Joseph Myers b040e1b084 Make soft-float powerpc swapcontext restore the signal mask (bug 21045). ... The soft-float powerpc version of swapcontext does not restore the signal mask, resulting in stdlib/tst-setcontext2 failing: after getcontext after setcontext after swapcontext FAIL: SIGUSR2 is blocked after swapcontext. This patch fixes this by adjusting the arguments passed to __sigprocmask so that it restores the saved signal mask as well as saving the existing one. (For hard-float, this code is only used for a compat symbol, not for the current version of swapcontext.) Tested for soft-float powerpc. [BZ #21045] * sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S (__CONTEXT_FUNC_NAME): Pass address of signal mask to be restored to __sigprocmask.		2017-01-16 21:34:48 +00:00
