it helps if one understands /why/ something is done. I think this
might be it for the reference count tweeks
switch.c:
o better control over whether case ranges are built
o /always/ append the temp = test expression and use temp instead of
test for the != check
o only ever build case ranges if the switch expression is integer
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.
expressions (ie, just a def) don't generated wasted assignments and clean up
switch's debug info so you get the switch line rather than the line for the
closing }
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.
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 =
