Bill Currie 64e50e1ebd Basic debug info generation, just line numbers and local defs for each
function.

Bill Currie 1edf1e0b39 format checking for error and warning + needed fixes
try to give name of object when calling non-function

Bill Currie 6dfee9968b /much/ better error handling 2001-06-28 21:26:40 +00:00
Bill Currie 0271afbb10 warn about the dangers of (!foo & bar) 2001-06-28 15:20:31 +00:00
Bill Currie 50ae388caa initialisations now seem to work, including cows (mooOOoo:) 2001-06-26 22:43:28 +00:00
Bill Currie d783a024b3 record an expression's line number and file and sort of handle state
expressions

Bill Currie c1753046a9 start on actually generating code. doesn't work yet (getting a weird type
redeclaration error and not all expressions are handled yet).

Bill Currie e99796c4cf new expression type: ex_block. forms a linked list of expressions for fast
appending and ease of manipulation.

Bill Currie 749d460041 duplicate code cleanup 2001-06-26 02:46:02 +00:00
Bill Currie 90b5c57266 fix lost initial char of string constants
make expression strings char * instead of string_t (don't put them into
pr_strings prematurely);

Bill Currie 53b66ef2e0 better label handling and strings are now completely parsed (including escapes) 2001-06-25 22:11:20 +00:00
Bill Currie 1779a124c5 expr.h:
nuke the ex_statement and estatement_[st] stuff
	add label_expr prototype
expr.c:
	ex_statement nukage
	correct new_expr's decl
	add label_expr to ease label creation
	don't crash when printing a null expression (bare return)
qc-parse.y:
	estatement_t nukage
	statement statements and statement_block are type expr
	generate `expressions' for statements

a full parse tree for each function is now generated. there are several
special expression opcodes for statements:
	d	done    \
	r	return  -> unary: expression to return or null
	i	if      binary:   evaluated expression, destination label
	n	ifnot   binary:   evaluated expression, destination label
	c	call    binary:   function def, args (expr list, rev order)
	s	state   binary:   frame const, function def
	g	goto    unary:    destination label
	l	label   unary:    label number
in a top level expression, l (label) defines the label, otherwise it is a
reference.

Bill Currie ab051248e8 expr.h:
add prototype for print_expr
expr.c:
	add print_expr
	correct string accessors
	currect the result type for unary operators
qc-lex.l:
	correct string, vector and quaternion parsing
qc-parse.y:
	precedence corrections and more function scope work

CustomTF gets through the parsing again.

Bill Currie aac91d8cd6 more expression handling. turns out I'm mis-parsing field types, so that's next 2001-06-20 21:18:04 +00:00
