           Summary: gcc-3.3.1 miscompiles c++ code with -O2, -fno-gcse cures
                    it
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: optimization
        AssignedTo: unassigned at gcc dot gnu dot org

  GCC host triplet: powerpc-unknown-linux
GCC target triplet: powerpc-unknown-linux

konqueror from KDE_3_1_BRANCH does not render http://www.spiegel.de/ correctly. 
the reason is a miscompilation in libkhtml.so.4.1.0, render_box.cpp is miscompiled. 
 
gcc-3.2.3 produces correct results, gcc-3.3.1 with -O1 as well, -O2 breaks it. 
adding -fno-gcse after -O2 produces correct code.

regression, worked fine in 3.2.3.
The suggested fixes for PR9745/PR10021 don't fix this one.

I wonder if the addition of the REG_EQUAL notes by GCSE is correct: 
 
 (insn# # # 0x33f37e00 (set (reg/v:SI 134) 
         (const_int 1 [0x1]))# {*movsi_internal1} (nil) 
     (expr_list:REG_EQUAL (const_int 1 [0x1]) 
         (nil))) 
 
 (insn# # # 0x33f37e40 (set (reg:SI 135) 
         (mem/s/j:SI (plus:SI (reg/v/u/f:SI 118) 
                 (const_int 24 [0x18])) [0 S4 A32]))# {*movsi_internal1} (nil) 
     (nil)) 
 
 (insn# # # 0x33f37e40 (set (zero_extract:SI (reg:SI 135) 
             (const_int 1 [0x1]) 
             (const_int 20 [0x14])) 
         (reg/v:SI 134))# {insvsi} (nil) 
-    (nil)) 
+    (expr_list:REG_EQUAL (const_int 1 [0x1]) 
+        (nil))) 
 
shouldn't that result in a REG_EQUAL (reg:SI 135) if anything?

No GCSE should not put the REG_EQUAL there.
Here is the definition of zero_extract's agruments:
/* Reference to a signed bit-field of specified size and position.   
   Operand 0 is the memory unit (usually SImode or QImode) which
   contains the field's first bit.  Operand 1 is the width, in bits.
   Operand 2 is the number of bits in the memory unit before the 
   first bit of this field.
   If BITS_BIG_ENDIAN is defined, the first bit is the msb and
   operand 2 counts from the msb of the memory unit.
   Otherwise, the first bit is the lsb and operand 2 counts from
   the lsb of the memory unit.  */

Provisional patch

This patch against the 3_3-branch fixes the testcase for me (no
bootstrap/regtest so far). I'm not 100% sure if it's the right place to reject
the note, but it looks reasonable to me. And do I need to reject
STRICT_LOW_PART and SUBREG too?
