Old Synopsis: Internal compiler error in extract_constrain_insn_cached
New Synopsis: [3.2/3.3 regression] Internal compiler error in extract_constrain_insn_cached
State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Wed Dec 4 13:40:03 2002
State-Changed-Why:
Confirmed. Here's a much smaller testcase:
-------------------------------
void f(unsigned long long int);
void g () {
register unsigned long long int i asm ("mm0");
f(i);
}
-------------------------
It ICEs with both 3.2 and 3.3 branches. It is a regression
w.r.t. 3.0.
With the above code, the crash happens with both the C and
C++ front ends, so I change the category to middle-end.
