From 7c7bcf3634e44cf7e001aaa302138c1ee0e58f8c Mon Sep 17 00:00:00 2001 From: Tulio Magno Quites Machado Filho Date: Fri, 10 Jul 2020 19:41:06 -0300 Subject: powerpc64: Fix calls when r2 is not used [BZ #26173] Teach the linker that __mcount_internal, __sigjmp_save_symbol, __syscall_error and __GI_exit do not use r2, so that it does not need to recover r2 after the call. Test at configure time if the assembler supports @notoc and define USE_PPC64_NOTOC. --- sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sysdeps/unix/sysv/linux') diff --git a/sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S b/sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S index e4d4575d68..3c528aa4b7 100644 --- a/sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S +++ b/sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S @@ -160,7 +160,7 @@ L(exitcode): li r3,-1 L(do_exit): #ifdef SHARED - b JUMPTARGET(__GI_exit); + b JUMPTARGET (NOTOC (__GI_exit)); #else b JUMPTARGET(exit); nop -- cgit 1.4.1
