Slava Pestov fc4894fbdf Replace ratio and complex built-in types with tuples defined in the library. This frees up two lo-tags, so move array and quotation over to these tags and update compiler for new tags 2009-04-30 00:27:35 -05:00
Slava Pestov c5160d76e9 Merge qualified, alias, symbols, constants into core 2008-12-17 18:10:01 -06:00
Slava Pestov eb79c6ab71 Fix conflict 2008-12-09 17:52:45 -06:00
Slava Pestov 8a8f0c925c Use BSR instruction to implement fixnum-log2 intrinsic 2008-12-06 15:31:17 -06:00
Slava Pestov a56d480aa6 Various optimizations leading to a 10% speedup on compiling empty EBNF parser:
- open-code getenv primitive
- inline tuple predicates in finalization
- faster partial dispatch
- faster built-in type predicates
- faster tuple predicates
- faster lo-tag dispatch
- compile V{ } clone and H{ } clone more efficiently
- add fixnum fast-path to =; avoid indirect branch if two fixnums not eq
- faster >alist on hashtables

Slava Pestov 908644ee7a O(1) <sbuf> and new-sequence on byte-arrays (work in progress) 2008-12-05 07:28:52 -06:00
Slava Pestov e256846acd Tweak string representation; high bit indicates if character has high bits in aux vector. Avoids memory access in common case. Split set-string-nth into two primitives; set-string-nth-fast is open-coded by optimizing compiler. 13% improvement on reverse-complement 2008-12-05 06:38:51 -06:00
Slava Pestov e7f4563374 fixnum* intrinsic for x86 2008-11-30 07:26:49 -06:00
Slava Pestov 68dd6cc35a Working on PowerPC overflow checks 2008-11-28 20:02:50 -06:00
Slava Pestov eb8c621b6f Faster generic arithmetic on fiixnums: both-fixnums? sub-primitive performs a check if the top two stack items are both fixnums with a single conditional branch 2008-11-28 08:35:02 -06:00
Slava Pestov f44506089d More work on overflow instructions: don't need temp register anymore, add -tail variants which don't need stack frame 2008-11-28 06:36:30 -06:00
Slava Pestov 5634becda1 ##fixnum-add, ##fixnum-sub instructions open-code overflow check 2008-11-28 05:33:58 -06:00
Slava Pestov 53cd75b06c Add string-nth intrinsic 2008-11-06 01:11:28 -06:00
Slava Pestov 82e9eedd39 Forgot about float= intrinsic 2008-11-03 07:15:09 -06:00
Slava Pestov 885adc8dc9 Various improvements 2008-10-23 05:27:54 -05:00
Slava Pestov df498c21a3 Trim USING: 2008-10-20 20:46:47 -05:00
Slava Pestov e92f795a76 More work on intrinsics; memory allocation and slot access now expands correctly 2008-10-20 20:40:15 -05:00
