Looks like a pre-Evan coalescer bug. Fixed here:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20080519/062735.html

Now the code snippet looks like this:
        movl    %edx, %edi
        movl    %ecx, %edx
        testl   %edx, %edx
        jne     .LBB1_47        # bb326
.LBB1_52:       # bb397
        testl   %eax, %eax
        je      .LBB1_80        # bb695
.LBB1_53:       # bb402
        movl    %esi, 4(%esp)
        movl    %eax, (%esp)
        call    get_cases_for_edge
        movl    (%eax), %esi
        movl    %esi, (%edi)

This correctly saves the previous iteration of "case" into "last" (%edi) and
used it as store address. Please verify this fixes Linux i386 llvm-gcc
bootstrapping.
