From 8b080534cadd8b9e920c8b023e341937a2e274bc Mon Sep 17 00:00:00 2001 From: Martin Erik Werner Date: Wed, 26 Jun 2019 17:44:54 +0200 Subject: [PATCH] or1k: Correct longjmp return value Invert equality check instruction to correct the return value handling in longjmp. The return value should be the value of the second argument to longjmp, unless the argument value was 0 in which case it should be 1. Previously, longjmp would set return value 1 if the second argument was non-zero, and 0 if it was 0, which was incorrect. --- newlib/libc/machine/or1k/setjmp.S | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/newlib/libc/machine/or1k/setjmp.S b/newlib/libc/machine/or1k/setjmp.S index 5c023278d..0b93a0342 100644 --- a/newlib/libc/machine/or1k/setjmp.S +++ b/newlib/libc/machine/or1k/setjmp.S @@ -70,7 +70,7 @@ longjmp: /* If the second argument to longjmp is zero, set return address to 1, otherwise set it to the value of the second argument */ l.addi r11, r0, 1 - l.sfne r4, r0 + l.sfeq r4, r0 l.bf 1f l.nop l.addi r11, r4, 0
