2005-03-01  Frank Ch. Eigler  <fche@redhat.com>

	* parse.cxx: Implement left-associativity for several types of
	operators.  Add some more statement types.  Parse functions.
	Be able to print tokens.  Simplify error generating functions.
	Save tokens in all parse tree nodes.
	* parse.h: Corresponding changes.
	* staptree.cxx: Move tree-printing functions here.  Add many
	new functions for symbol and type resolution.
	* staptree.h: Corresponding changes.
	* semtest.cxx: New semantic analysis pass & test driver.
	* testsuite/sem*/*: New tests.
	* parsetest.cxx: Separated parse test driver.
	* testsuite/parse*/*: Adapt tests to parsetest driver.
	* Makefile.am: Build semtest.  Run its tests.
	* Makefile.in: Regenerated.

	* parse.cxx, parse.h: New files: parser.
