Created attachment 498271 [details] [diff] [review] patch (against TM 58597:dab87d48d3dd) JITScript is sub-optimally packed on 64-bit platforms. The attached patch reduces its size from 232 to 200 bytes. On a 20-tab cad-comics browser run, this saves 357,102 bytes. It's a small win, but it's a dead-simple patch.
A |bool singleStepMode| field was added since I created the patch, I squeezed that into the bottom bit of |nCallSites|. http://hg.mozilla.org/tracemonkey/rev/35697ebafa6c
As per today's meeting, beta 9 will be a time-based release. Marking these all betaN+. Please move it back to beta9+ if you believe it MUST be in the next beta (ie: trunk is in an unshippable state without this)
Fixing fields my automated script accidentally blanked. Apologies for the bugspam
