           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: target
        AssignedTo: unassigned at gcc dot gnu dot org

Hi, the following testcase (extracted from Mesa sources) fails to compile on
current 3.3-hammer and 3.4 (20030723) with "-O -march=pentium3 -mfpmath=sse".
This is a regression from plain 3.3-branch.

/* { dg-do compile { target i?86-*-* } } */
/* { dg-options "-O -march=pentium3 -mfpmath=sse" } */

static void f ()
{
  unsigned ui[2];
  int i;
  i = (float)ui[0];
}

[gb@hp6 gcc]$ ./cc1 --version
GNU C version 3.4 20030723 (experimental) (i686-pc-linux-gnu)

[gb@hp6 gcc]$ ./cc1 -O -march=pentium3 -mfpmath=sse ~/vrac/i386-ssefp-3.c

I can confirm this fails on the mainline (20030725).

Indeed to be found on mainline, too. So change summary line and
target milestone.

It does not fail on 3.3.1 (20030707), this is not a 3.3 regression, it only fails on the mainline and 
the 3.3-hammer branch.

Are you sure? Though I can reproduce on 3.3-hammer branch, I can't 
reproduce that on 3.3-branch, nor 3.3-rhl-branch, at least as of:
GNU C version 3.3.1 20030721 (prerelease) (i686-pc-linux-gnu)

Sorry, guys, I was just misreading the intent of the [x.y/... regression] marker.
Thanks for cleaning up after me.

The regression in PR 11674 was introduced or exposed by this patch:

--- gcc/gcc/ChangeLog ---

Wed Feb  5 23:12:57 CET 2003  Jan Hubicka  <jh@suse.cz>

        * i386-protos.h (x86_emit_floatuns):  Declare.
        * i386.c (x86_emit_floatuns): New global function.
        * i386.md (floatunssisf2, floatunsdisf2,
        floatunsdidf2):  New patterns.

The regression hunt took place on i686-pc-linux-gnu using the test
case from the PR compiled with "-O -march=pentium3 -mfpmath=sse".
