The expanded warning allowed me to see how much memory really was needed
to apply gcse to some of my routines, and 128MB fixes my problem.  The
limit has been 50MB for over 10 years, I think we can up it a bit now.
  {
+  unsigned int memory_request = n_basic_blocks_for_fn (cfun)
+    * SBITMAP_SET_SIZE (max_reg_num ())
+    * sizeof (SBITMAP_ELT_TYPE);
+

Formatting (wrap in parens to get it indented). Could also move theinitialization before the use.


Otherwise ok.
