9b784e331b remove '(' (never used, don't remember what it was intended for) and add
'b' (bind), 's' (state) and 'c' (call) to get_op_string.

c5d0d45edf qfcc: Remove some debug info from taniwha's last commit -- I thought
*I*'d done that! :)

5cbd50d835 count the number of digits needed rather than relying on -lm (now it's not
needed:)

f8a41cb1bc completely nuke the concept of "priority" from opcodes and use get_op_string
in emit_sub_expr instead of a redundant switch.

f029687ff0 switch statement. could do with lots of improvements, but this should be a
good start.

3bba5398ba - audit malloc usage. now everything checks the return value :) 2001-10-24 22:50:06 +00:00

2ef8adea09 handle more conditional code and check for unitied vars in the test of if ()
etc

5ca785e7e8 uninitialized variable detection. not perfect (lots of false negatives, but
fewer than before;) but prozac isn't giving any false positives.

79ac85b54f type checking now works much better and there is now a NIL builtin constant
which can be assigned (/only/) to anything.

dcb51dc586 expr.h:
get_type and extract_type prototypes and add extern for type_names
emit.c:
	use extract_type instead of get_type
expr.c:
	get_type now returns the type pointer rather than the qc type enum.
	extract_type uses get_type to return the qc type enum.
	make type_names global
	use get_type instead of ex_expr/ex_def to cover more cases
	clean up function call/return processing as a result of get_type
pr_opcode.c:
	use opcode_priority_type_table_ab when var_c is null and a minor
	cleanup in PR_Opcode_Find

ea451ab02d Remove unnecessary temps from function return values. This has one
*/CRITICAL/* implication: DO NOT /EVER/ RELY ON EVALUATION ORDER. This
isn't /really/ that bad: evaluation order will be consistent for similar
expressions, but for (eg) foo() + bar()*2, bar will be called first.
2001-08-24 21:47:52 +00:00
Bill Currie
08f73bed78 better code generation for foo(bar(baz)). foo(snafu,bar(baz)) isn't optimal
yet, but the code is at least correct
2001-08-24 21:14:04 +00:00
Bill Currie
eeec89e6ba don't put function args in temps when not needed. still need to take care
of the return value, but that can possibly be taken care of in an optimiser
pass.

4c48851096 fix a buffer overflow in new_label_expr
use reference counting for temp defs and call PR_FreeTempDefs at the end
of emit_sub_expr as well as emit_expr.

c2d3d8f3ab temp def expressions and ?:
seems to work :)

6414897dae got a few new operators for qc :)
<< >> % which all act like their C counterparts
+= -= *= /= &= ^= |= <<= >>= %= which just expand into the obvious,
also like the C versions.
2001-08-10 16:17:00 +00:00
Bill Currie
081d8f3c47 ^ and ~ operators for qc (^ from Rhamphoryncus) and clean up the punctuation
line in qc-lex.l (why didn't I think to do that in the first place?!?)

b341529fce more --id support 2001-08-07 16:50:22 +00:00

1e1cb06a1f disable integers for --id. probably not thorough enough yet :/ 2001-08-03 07:47:15 +00:00

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:/)
2001-07-25 21:47:05 +00:00

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

9ad075b02e make if/while/for use test_expr, make test_expr fix the new exp line/file,

576123060a warn on passing integer constants into ... functions. Again, this will need
an option later
2001-07-24 20:43:18 +00:00

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
2001-07-24 19:51:44 +00:00

6d1671950a expr.c:
warn for int const / int const. this will probably want an option for newer
	games
qfcc.c:
	clean up temp files when errors have occured
