As described in a recent glibc thread [1], the rt_sigreturn syscall on setcontext and swapcontext is not used on default use and its intention is no really supported since neither setcontext nor swapcontext are async-signal-safe. Checked on powerpc64-linux-gnu and powerpc-linux-gnu. * sysdeps/unix/sysv/linux/powerpc/powerpc32/setcontext-common.S: Remove rt_sigreturn call. * sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S: Likewie. * sysdeps/unix/sysv/linux/powerpc/powerpc64/swapcontext.S: Likewise.
