5d9de143af More concise conversion from object to boolean. 2008-06-27 07:48:18 -07:00
Andreas Gal
afd5f3b1e3 Clarified argument names in guard code and explain better why we guard for overflow the way we do. 2008-06-27 07:28:10 -07:00
Andreas Gal
a13289ec80 Added missing > which has been bugging me for the past month every time I saw it. 2008-06-27 07:21:37 -07:00

e59076860a Instead of guarding on null -> boolean conversion just emit a null compare and use the boolean result. 2008-06-27 06:53:10 -07:00
Andreas Gal
3492763c96 Throw out a bunch of primitives (guards) that we are no longer interested in. 2008-06-27 06:18:12 -07:00

17d189ecb9 Eliminate boxing in trace code. To execute such traces all values on the stack must have the same type at execution time as at trace time. Code to detect and enforce these types will be added next. 2008-06-22 21:32:24 -07:00

Andreas Gal
3197b76462 Mork work on attaching nanojit to our primitives. Traces have now their own box type (Box), which is an opaque 64-bit value. Its never supposed to appear in the trace since we will optimize away all boxing operations. 2008-06-21 22:28:41 -07:00
Andreas Gal
78da0668af Start attaching our tracer to nanojit. This is incomplete and meant for review by David only. 2008-06-21 14:55:32 -07:00
