[Bug middle-end/38535] New: [4.4 Regression] __builtin_ia32_stmxcsr no longer works

[hjl dot tools at gmail dot com]

When I configured gcc with --enable-languages=c, I got

[...@gnu-6 gcc]$ cat x.c
unsigned int
foo ()
{
  return __builtin_ia32_stmxcsr ();
}
[...@gnu-6 gcc]$ ./xgcc -B./ -O2 -S x.c 
x.c:1: internal compiler error: tree check: expected class ‘type’, have
‘exceptional’ (tree_list) in type_hash_list, at tree.c:4570
Please submit a full bug report,
with preprocessed source if appropriate.
