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.
