Subject: [Bug target/19235] [4.0 regression] GCC generates SSE2 instructions for AthlonXP which doesn't support them.
Date: Mon, 03 Jan 2005 10:30:00 -0000 [thread overview]
Message-ID: <20050103103015.17766.qmail@sourceware.org> (raw)

------- Additional Comments From uros at kss-loka dot si 2005-01-03 10:30 -------
This bug could be caused by:
2004-12-17 Richard Henderson <rth@redhat.com>
* config/i386/i386.c (x86_64_reg_class_name): Re-indent.
...
(movsi_1): Use 'x' instead of 'Y' constraints.
(movsi_1_nointernunit, movdi_2, movdi_1_rex64): Likewise.
(movdi_1_rex64_nointerunit): Likewise.
(movdf_nointeger, movdf_integer): Likewise. Handle SSE1. <<<
...
There is a problem with register constraints in movdf_nointeger pattern. It
looks that 'x' should be substituted by 'Y'. Patch is in testing.
