5f5060cbf0 move the users and used setting code from emit_statement to 
PR_AddStatementRef. This removes essentially duplicate code and 3 ifs :)

b499d7e1e8 I've decided that shuffling the `sections' like that doesn't really gain 
anything, so I'm reverting that change.

Bill Currie
3b2d2a1c88 re-arrange the order of the `sections' of a .dat file to match the header 
order. this also `happens' to put the strings section just before the globals
section (both at the end) which will make pointer bounds checking easier.

Jeff Teunissen
b07d60f6d6 add getopt.c and getopt1.c to the makefile. There is preprocessor 
stuff in these files to detect when they need to be compiled, so they
don't need anything in configure.

f8a41cb1bc completely nuke the concept of "priority" from opcodes and use get_op_string 
in emit_sub_expr instead of a redundant switch.
 2001-10-25 17:48:35 +00:00

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

Bill Currie
133ce647fb implement break and continue. only loops covered for now, but that's because 
switch isn't implemented yet

5ca785e7e8 uninitialized variable detection. not perfect (lots of false negatives, but 
fewer than before;) but prozac isn't giving any false positives.
 2001-10-18 20:05:26 +00:00
Bill Currie
96e4e1a232 the beginning of unititialized var detection. first victim: functions. 
--undefined-function-warning is now --no-undefined-function-warning and
the default is to detect called but undefined functions.

which can be assigned (/only/) to anything.

Bill Currie
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

Bill Currie
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.

c218ede288 Add support for checkfunction, which is a builtin that searches for 
another builtin by name, and returns it.

Soon I'll change all our new builtins to by allocated dynamically, as
well as changing the number checkfunction uses, and happily break
everything that uses them :D

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  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:

	   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

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

	l	label   unary:    label number

bbb37d0080 customTF is now down to 4989 pr_globals. all parameters, local veriables and 
termporary variables sit in one pool of memory (at the end of the globals)
thus drasticly reducing globals requirements. This works because the whole
lot is declared to be in the function's local variable space which is copied
to the locals stack in the progs engine.
