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
*/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.
use reference counting for temp defs and call PR_FreeTempDefs at the end
of emit_sub_expr as well as emit_expr.
fix a (relatively harmless) bug in type processesing of foo.bar =
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
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
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.
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.
rearrange def_t a little and add def_next (leaving next free for other
uses)
pr_def.c:
use def_next instead of next to link /all/ of the named defs
qfcc.c:
ditto
define PROG_ID_VERSION as 6 and redefine PROG_VERSION as 0x00fff001
(0.fff.001) for the new qc features.
pr_edict.c:
support version 6 and version 0.fff.001 progs
qfcc.h:
add version field to options_t
add min_version field to opcode_t
pr_opcode.c:
set the minumum version of each opcode (gee, that table is getting ugly)
filter out opcodes with too high a min_version when initializing the opcode
hash tables.
qfcc.c:
update help output.
accept --id to limit code generation to id compatable (ver 6) progs.
default progs generation to 0.fff.001
Detect assignments to initialized globals and give an error, unless the --cow
(copy on write) option is given, and then allocate a new global for the var,
clear its initialized flag.
Relocate all globals.
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.
