Subject: [Bug target/19161] No emms or femms emitted between MMX and FP instructions
Date: Fri, 04 Jan 2008 22:44:00 -0000 [thread overview]
Message-ID: <20080104200555.26222.qmail@sourceware.org> (raw)
In-Reply-To: <bug-19161-119@http.gcc.gnu.org/bugzilla/>
------- Comment #22 from Richard dot Barnes at stratus dot com 2008-01-04 20:05 -------
I have seen this bug in the vector-2 testcases shipped in
gcc/gcc/testsuite/gcc.dg/compat when compiling for i386 with -msse2. In
vector-2_y.c and vector-2_x.c we end up using both mmx and x87 registers in the
same function without any intervening EMMS instruction. This fails in 4.1.2,
3.4.6, and 3.3.1.
