o add a "freed" marker to def_t to prevent double freeing of
temp def offsets
emit.c:
o break out the bind code into emit_bind_expr (doesn't /really/
emit code, but still:)
o make bind work with disparate types (forces def_t->freed 1)
pr_def.c:
o mark array pointers as initialized and constant.
o don't free the offset for already freed temp defs
pr_imm.c
o fix a bug in uinteger support
o support disparate types for immediates
switch:
o fix a bug where gt.i was being used instead of gt.ui
o remove some debug code
o add OP_JUMPB
o OP_JUMPB renumberd some opcodes, so up PROG_VERSION
pr_edict.c:
o make the version error reporting more informative
pr_exec.c:
o implement OP_JUMPB (goto *(ptr + index))
pr_opcode.c: (libs/gamecode/engine)
o add OP_JUMPB to the table
expr.h:
o ex_uinteger support
o some const correctness
o prototype new_label_expr
qfcc.h:
o uinteger ussport
o add pointers for op_jump and op_jumpb
o prototype PR_GetArray
emit.c:
o general uinteger support
o new reference/reloc type 3: absolute statement address
o jumpb support (binary goto)
expr.c:
o uinteger support
o break the label name creation out of new_label_expr into
new_label_name
o some const correctness
pr_def.c:
o add PR_GetArray to allocate an array in global space
o factor out some code common to PR_GetDef and PR_GetArray that would
otherwise be duplicated
pr_imm.c:
o some const correctness
o uinteger support
pr_lex.c:
o uinteger support
pr_opcode.c: (tools/qfcc/source)
o support jump and jumpb
switch.c:
o rewrite the binary search code to support ranges.
o add ev_uniteger to the types enum
o add opcodes for ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
progs.h:
o add uinteger accessors
pr_exec.c:
o implement ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
pr_opcode.c:
o add opcodes for ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
expr.h:
o prototype inc_users
qfcc.h:
o add externs for op_ifbe, op_ifb, op_ifae and op_ifa
emit.c:
o don't bother emiting an assignment to a temp def that's only used once
(ie, it's never read, only written to)
o support the new if* instructions
expr.c:
o support the new if* insructions
o dectect expression loops in append_expr
o support unsigned integers
o re-work temp def usage counting
pr_def.c
o debugging for temp def usage counts
pr_opcode.c:
o support the new if* instructions
qc-parse.y:
o provide defines for IFBE IFB IFAE IFA
switch.c:
o do binary searches for strings, floats and ints if there are more than
8 cases in a switch. Strings need more testing.
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 =
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
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.
WARNING: this fixes a scope bug in qcc and thus you WILL get different (but
now correct) code for the following:
float foo;
void () bar =
{
local float foo;
foo = 0;
}
ie, the local foo will, as is correct, now be a separate var to the global
foo.
