           Summary: [4.7 Regression]
                    libstdc++-v3/testsuite/decimal/incdec.cc FAILs with -O
                    -fno-tree-dce -fno-tree-fre -fno-tree-sra -m32
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: zsojka@seznam.cz
              Host: x86_64-pc-linux-gnu
            Target: i686-pc-linux-gnu


Created attachment 23889
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23889
reduced testcase

Output:
$ g++ -m32 -O -fno-tree-dce -fno-tree-fre -fno-tree-sra testcase.C
$ ./a.out 
Aborted

Diff between 4.6 and 4.7 output shows this:
L8:
    mov    DWORD PTR [esp+4], 847249419    #,
+    mov    DWORD PTR [esp], 847249419    #,
    call    __bid_nesd2    #

There seems to be one store to [esp] missing in 4.7 (marked by "+").

Tested revisions:
r171998 - fail
4.6 r171597 - OK
