Subject: [Bug target/35907] [4.3/4.4 Regression] 64-bit power6 glibc miscompilation
Date: Fri, 11 Apr 2008 14:32:00 -0000 [thread overview]
Message-ID: <20080411143151.18013.qmail@sourceware.org> (raw)
In-Reply-To: <bug-35907-87@http.gcc.gnu.org/bugzilla/>
------- Comment #3 from jakub at gcc dot gnu dot org 2008-04-11 14:31 -------
On this smaller testcase and supposedly on the large testcase too:
@@ -90,7 +90,7 @@ foo:
li 3,0
lvx 30,1,0
li 0,128
- lvx 31,1,0
+ lvx 31,31,0
ld 1,0(1)
lwz 12,-28(1)
mtvrsave 12
fixes this (r31 is frame pointer, set to r1 around the stvx that saved v31,
but at the lvx 31,1,0 instruction r1 is r31 decreased by alloca calls).
