d44f60f17c drasticly simplify emit_assign_expr now that I have a much better 
understanding of when an explicit assigment is needed. seems to work for
everything I throw at it.
Also, fix ! unary ops (caused by the - unary op fix:/)

0c2cd8633c fix -expr handling. generates sucky code atm, but at least it's generating 
code now:P

576123060a warn on passing integer constants into ... functions. Again, this will need 
an option later

d9cde786b3 use ev_type_count instead of ev_void for bad types so things like void 
functions being used in expressions don't cause ICEs

c248372e20 Initial integer type support. qfcc /is/ partially broken when it comes to 
integer constants and float function args/return values.

pr_comp.h:
	o  add the integer opcodes to pr_opcode_e
pr_edict.c:
	o  add "quaternion" and "integer" to type_name[]
	o  support quatnernion and integers types when printing values
	o  support the integer opcodes when bounds checking
pr_exec.c
	o  enable the integer opcodes
pr_opcode:
	o  add the integer opcodes to the opcode table
	o  logical operators all result in an integer rather than a value
expr.h:
	o  rename int_val to integer_val
qfcc.h:
	o  kill another magic number
expr.c:
	o  move the opcode to string conversion out of type_mismatch and into
	   get_op_string
	o  rename int_val to integer_val
	o  general integer type support.
	o  generate an internal comipiler error for null opcodes rather than
	   segging.
pr_imm.c:
	o  rename int_val to integer_val
	o  support integer constants, converting to float when needed.
pr_lex.c:
	o  magic number death and support quaternions and integers in type_size[]
qc-lex.l
	o  rename int_val to integer_val
	o  support quaternion and integer type keywords
qc-parse.y:
	o  rename int_val to integer_val
	o  use binary_expr instead of new_binary_expr for local initialized
	   variables
builtins.c:
	o  rename int_val to integer_val
	o  fix most (all?) of the INT related FIXMEs
defs.qc:
	o  use integer instead of float where it makes sense
main.c:
	o  read_result is now integer rather than float
main.qc:
	o  float -> integer where appropriate
	o  new test for int const to float arg

55ac55c7ac rename ev_int and ex_int to ev_integer and ex_integer. create type_integer 
and def_integer (do I need that?), clean up and or coment on XXX and FIXME
 2001-07-22 06:59:12 +00:00

7c16afe7e9 add a --no-cpp command line option so that cpp enabled qfcc can still compile

47a6f2c9b5 pr_debug.c: 
capitolise CRC and add a \n to the message
sv_progs.c (both nq and qw):
	don't bother checking the progdefs.h crc: it's just not needed any more
pr_imm.c:
	use r instead of rep when checking the hash tables.
main.c (quaq):
	make developer work and set com_filesize (otherwise, progs crc doesn't
	get set properly (com_filesize, not developer:))

10ad8bebbd Make files.dat actually useful. I really dislike the hardcoding, but it /is/ 
useful. Also, fix a bug in PrecacheModel where it was checking MAX_SOUNDS and
numsounds instead of models.
 2001-07-18 17:23:42 +00:00

c9af1575d3 fix emit_assign_expr to emit an explicit assignment statement whenever 
emit_sub_expr returns a temporary def. this fixes a = b = c; expressions when
entities are involved.

a0ba8e534c s/IMMEDIATE/.imm/ for name of immediate defs. the latter is both shorter and 
impossible to generate from qc

2818d720c2 move the full info opcocde table from qfcc to gamecode (<KURGON>There can be 
only one!</KURGON>:) and use the table in PR_PrintStatement. This means that
qfcc now links against libQFgamecode as well as libQFutil

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.
