This would leave sizeof(JSStackFrame) == 6 words.
Members to remove
Sorted in estimated order of benefit / difficulty:
| Task | Size (wks) | Assignee | Note |
| argc/argv | 1.5 | lw | Requires CallSegment (CallStack) changes, educate decompiler |
| thisv | .5 | lw | Depends on argv/argc |
| fun, script | .5 | lw | Depends on thisv |
| ncode | .1 | dvander | Merge it with savedPC in method-jit |
| displaySave | 1 | cdleary | Remove display optimization for great justice! |
| hookData | .2 | lw | Just use js::Invoke and use a local variable |
| annotation | 0 | sayrer | Trivial if we can remove callers in nsScriptSecurityManager. |
| callerVersion | .5 | Mostly the challenge is just understanding the actual use case. | |
| blockChain | 1 | lw | A bit tricky |
| rval | 1 | Tricky | |
| imacpc | 1 | Perhaps push on the expression stack like JSOP_GOSUB does |
Method-jit changes
- PIC for fast natives calls
- PIC/fast path for interpreted inline call
