Slava Pestov cc5476c823 _gc instruction doesn't need slot to hold GC root area size, since that's just tagged-values>> length 2009-08-09 03:08:13 -05:00
Slava Pestov e21ca289c3 compiler.cfg.representations: new pass to make global unboxing decisions, relies on new compiler.cfg.loop-detection pass for loop nesting information 2009-08-08 00:24:46 -05:00

Slava Pestov 44bfff7c7b Rename ##load-indirect to ##load-reference since this is more descriptive; value numbering doesn't assign expressions to ##load-reference nodes since this would end up folding literals which were eq? but not = 2009-01-29 01:44:58 -06:00
Slava Pestov 8a8f0c925c Use BSR instruction to implement fixnum-log2 intrinsic 2008-12-06 15:31:17 -06:00

- inline tuple predicates in finalization
- faster partial dispatch
- faster built-in type predicates
- faster tuple predicates

Slava Pestov eb05dd3a12 Optimize a ##dispatch that is applied to the result of a ##sub-imm or ##add-imm; this eliminates an instruction from the common 1 fixnum-fast { ... } dispatch and 8 fixnum-fast { ... } dispatch code sequences appearing in generic word expansions 2008-11-13 04:16:08 -06:00
