New Revision: 178988

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=178988
Log:
Restructure pph_read_tree_header and pph_read_tree to do what their
names say they do.  In particular, generic tree handling from
pph_read_tree_header to pph_read_tree.

Add debugging routines pph_tree_code_text (to avoid out of bounds
indexing on a bad tree code) and pph_dump_min_decl (to dump the
minimal decl information).

Rename the preprocessor lookaside table field pth_debug_level to
debug_level (as PTH is gone).  Adjust thess debug levels to mean
0 == none, 1 == statistics, 2 == verbose.  Adjust the initialization
in pph_init to reflect that.

Tested on x64.

	* pph.h (pph_tree_code_text): New.
	(pph_dump_min_decl): New.
	* pph.c (pph_tree_code_text): New.  Update users of tree_code_name
	to call this function instead, here and in other files.
	(pph_dump_min_decl): New.
	(pph_init): Adjust debug value to preprocessor's value.
	* pph-streamer-in.c (pph_read_tree_header): Move work unrelated to
	tree headers out of this function.
	* (pph_read_tree): Move that work here.
	* pt.c (pph_in_spec_entry_htab): Use pph_logfile instead of stderr.
