Subject: Re: target/10077: gcc -msse2 generates movd to move dwords between xmm regs
Date: Fri, 14 Mar 2003 15:12:00 -0000	[thread overview]
Message-ID: <20030314151208.30354.qmail@sources.redhat.com> (raw)

Synopsis: gcc -msse2 generates movd to move dwords between xmm regs

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Fri Mar 14 15:12:08 2003
State-Changed-Why:
    I can confirm this: it leads to an assembler error with
    3.2.2 and 3.3, but not with 3.4:
    
    g/x> /home/bangerth/bin/gcc-3.3-pre/bin/gcc -c gcc_bug.i -msse2 -O3
    /tmp/ccn5g6XV.s: Assembler messages:
    /tmp/ccn5g6XV.s:127: Error: suffix or operands invalid for `movd'
    
    I leave it to others to find out where this problem comes
    from. Since mainline compiles and assembles this file
    just fine, this seems indeed like a problem in the compiler.
    
    The instruction in question is this one:
    	movd	%xmm7, %xmm3
    
    W.
