This patch updates the make clean target and modifies the vpath search to
match what is done in the main ivl Makefile since this one has the same
issues it does. It also adds a cppcheck target and removes the redundant
libmisc build target since the vpath already handles this.
This patch fixes the ivl build to find files in libmisc using vpath instead
of a separate target. The existing constructs caused build problems after
running a make clean. It also adds an empty checking target to vhdlpp.
Include the compiler infrastructure to vhdlpp for collecting the
file and line information and attaching it to entities and ports.
Make the parser store the file name during parse.
Create a libmisc library where I can put source files that are
used by multiple programs within the source tree.
Add enough rules to parse a simple VHDL program:
Parse library and use clauses,
Parse entity declarations, and
Parse architecture bodies.
Add some parser infrastructure:
Handle syntax errors with useful error messages,
Include file name and line numbers in parse errors,
Add some parser debug aids.
