- Switch improvements:
- JSOP_CONDSWITCH is a 1 byte nop, not variable length with the same kind
of immediate operand as JSOP_LOOKUPSWITCH (which is useless except for
decompilation). New scheme uses SRC_COMMA notes on each JSOP_CASE opcode,
usually 2 bytes per note, and a typically-1-byte 2nd offset on SRC_SWITCH:
1 + 2 * ncases
vs. the previous JSOP_LOOKUPSWITCH immediate, which consumed:
4 * ncases
bytes after the switch opcode just for decompilation.
- SRC_SWITCH has two offsets, first to end of switch as before, the second
to first case if JSOP_CONDSWITCH, for decompilation.
- Optimize switches with all-constant cases using JSOP_TABLESWITH, or if
that can't be used, JSOP_LOOKUPSWITCH, before falling back on ECMAv2's
JSOP_CONDSWITCH.
- Use cx->gcDisabled when evaluating case exprs at compile time for old,
pre-ECMAv2 switches, to prevent branch-callback-based GC invocations
from ripping apart the unrooted temporary script for each case expr.
- Fixed up stale SRC_SWITCH comments in jsemit.h.
jsemit.c jsemit.h
- TREE_CONTEXT_INIT to match ATOM_LIST_INIT, not English word order.
- Reorganized JSCodeGenerator to sort of match argument order to
js_InitCodeGenerator.
- Got rid of confusing CG_RESET* macros and used memset(cg, 0, sizeof *cg)
and non-zero-default init in js_InitCodeGenerator. js_ResetCodeGenerator
just releases the code and temp arena pools and leaves the cg in a state
where it must be re-initialized (as before, but more obvious).
- In the same spirit, don't do partial "resets" or src and trynotes in their
js_FinishTaking*Notes functions -- those are friends of jsscript.c and are
not general, idempotent functions.
jsapi.c jsapi.h jsarray.c jsatom.c jsatom.h jscntxt.c jsemit.c jsmsg.def
jsnum.c jsobj.c jsopcode.c jsregexp.c jsscan.c jsstr.c jsxdrapi.
- Use PR_snprintf rather than sprintf always, so we don't have to worry
about systems with 64-bit longs that overflow 12-byte buffers and open
Morris-Worm-type security holes.
- Trim extra spaces, fix hanging indentation, and similar anal retention.
- Renamed JSMSG_BAD_PROTO_SORT to JSMSG_BAD_SORT_ARG cuz that's what it
is complaining about.
- SRC_CATCHGUARD still lived in comments, but it's SRC_CATCH in code.
jscntxt.c jscntxt.h jsinterp.c
- Packed nearby JSPackedBools and added a new one: gcDisabled, for use by
jsemit.c's pre-ECMAv2 switch case expr eval.
- Rip out old js_InterpreterHooks stuff from original liveconnect (moja).
- Remove javaData and savedErrors from JSContext. Leaving it to fur or
shaver to remove javaData from jsscript.h.
