Hi,
Can a gatekeeper review the patch for bug 591?
http://bugs.open64.net/show_bug.cgi?id=591. Thank you very much.
The source code is:
_Complex float f (_Complex float b, _Complex float c)
{
_Complex float a = 1.0 + 0.0i;
return a / c;
}
The assertion happens in WN_lower. Before LOWER, the IR is:
C4DIV
C4STID
In lower_complex_expr, when lowering C4DIV, the tree has been deleted at
line 2856. In lower C4STID, the DIV is deleted again at line 8192. The fix
is to remove the second one.
