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

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

53060c32ce Move all inlines that do not represent primitives out of jsinterpinlines.h since we don't have to overwrite them in jstracerinlines.h. They live in jsinterp.cpp now.
