           Summary: Regression in g++.dg/parse/stack1.C
           Product: gcc
           Version: tree-ssa
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code, xfail
          Severity: normal
          Priority: P2
         Component: middle-end
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: rth at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org

This test case has 11,000 chained else if's.  We fail because gimplify_cond_expr
isn't written to allow tail-calling, and exhaust stack space.  There's enough
complexity in that function that the transformation would be non-trivial.

The test will be xfailed on the branch, but must be fixed before merging.

Looks like his stack limit is high.  The reason why it is faster on the tree-ssa branch is because all 
the if's are gone when converting from trees to rtl.

XPASS's on i386-unknown-freebsd4.9, alphaev67-unknown-linux-gnu, i686-pc-linux-gnu 
(depends on the stacksize).

Note now (with sibling call on the tree level, some functions are not sibcalled, already 
filed another bug for it): the backtrace looks like this:

gimplify.c:3030

Another way to fix this part of the back trace is define the LANGHOOK to return the enum, 
I am testing a patch for that.

Hmm (at least on ppc-darwin), with --disable-checking this works but without we get a stack overflow.

Is this still an issue, and if so, is it fixable for GCC 4.0?

The testcase is now fixed but the fundamental problem with the gimplifier still exists.  So this is no
