Slava Pestov 7e2f0e5dbf compiler: separate ##save-context instruction from ##alien-invoke, generate a ##save-context for libm calls, and add a pass to combine multiple context saves within a basic block. Fixes crashes with FP traps thrown by libm functions on x86-32 2009-09-08 21:50:55 -05:00
Joe Groff 0ea9949e51 split unordered and ordered float comparison intrinsics in compiler; generate only unordered comparisons for now 2009-09-08 17:04:26 -05:00
Slava Pestov 1e5bc3b376 inline alien-vector and set-alien-vector if SIMD is not available for a small speedup 2009-09-08 13:56:17 -05:00
Slava Pestov e36a0d7ef4 compiler: clean up code generation for alien boxing/unboxing a bit 2009-09-03 21:22:43 -05:00
Slava Pestov 4d5a4222b6 More SIMD work
- Rename SIMD types and register representations: <type>-<count> rather than <count><type>-array
- Make a functor to define 256-bit vector types, use it to define float-8 type
- Make SIMD instructions pure-insns so that they participate in value numbering

Slava Pestov ff8c70dbe0 Initial implementation of SSE vector intrinsics:
- cpu.architecture: add SSE vector representations
- compiler.cfg.intrinsics.alien: remove an attempt at optimization that value numbering handles now
- compiler.cfg.representations: support instructions where the representation is set in the 'rep' slot, and support conversions between single and double floats
- alien-float, set-alien-float now use the single float representation, and the conversion is implicit; this fixes a long-standing bug where a register could get clobbered because of how %set-alien-float was defined on x86
- math.vectors.specialization: add support for SIMD specialization (where the vector word's body is replaced by another quotation), also specialize the 'sum' word
- math.vectors.simd: 4float-array, 2double-array, 4double-array types, and specializers for the math.vectors words

Slava Pestov 85a2bfab6c compiler: eliminate boilerplate by centralizing info in declarative INSN: syntax 2009-09-02 06:22:37 -05:00
Slava Pestov 9595be4bf9 %box-displaced-alien: fix clobberage found by Doug 2009-08-30 05:11:08 -05:00
Slava Pestov 0db01f6d5f compiler.cfg.linear-scan now supports partial sync-points where all registers are spilled; taking advantage of this, there are new trigonometric intrinsics which yield a 2x performance boost on benchmark.struct-arrays and a 25% boost on benchmark.partial-sums 2009-08-30 04:52:01 -05:00
Slava Pestov 2bb6293217 compiler: add fixnum-min/max intrinsics; ~10% speedup on benchmark.yuv-to-rgb 2009-08-28 19:02:59 -05:00
Slava Pestov d957ae4e44 Performance improvements to make struct-arrays benchmark faster
- improved optimization of ##unbox-any-c-ptr on ##box-displaced-alien; convert it to ##unbox-c-ptr where possible using class info stored in the ##bda instruction
- make fcos, fsin, etc inline again; everything in math.libm inline again, except for fsqrt which is an intrinsic
- convert min and max on floats to float-min and float-max
- make min and max not inline, so that the above can work
- struct-arrays: rice a bit so that more fixnums come up

Slava Pestov f662e6403a compiler: new inline intrinsic for <displaced-alien> where the inputs have known types; value numbering now eliminates unnecessary allocation of displaced aliens if the result is immediately unboxed again 2009-08-27 00:06:19 -05:00
Slava Pestov 0df8aadce2 cpu.x86: use SQRTSD instruction for math.libm:fsqrt word 2009-08-25 23:22:15 -05:00
Slava Pestov 4b7ba38aab compiler.cfg: virtual registers are integers now, and representations are stored off to the side. Fix bug in representation selection that would manifest if a value was used as a float and a fixnum in different branches; cannot globally unbox float in this case 2009-08-08 04:02:18 -05:00
Slava Pestov 725280d424 Split off the notion of a register representation from a register class 2009-08-07 17:44:50 -05:00
Slava Pestov 45770c6250 Move a bunch of GC check generation logic to platform-independent side 2009-07-30 21:28:27 -05:00
Slava Pestov be363d1a5b compiler.cfg: Get inline GC checks working again, using a dataflow analysis to compute uninitialized stack locations in compiler.cfg.stacks.uninitialized. Re-enable intrinsics which use inline allocation 2009-07-30 09:19:44 -05:00
Slava Pestov 3fb4fc1bde Improve code generation for shift word: add intrinsics for fixnum-shift-fast in the case where the shift count is not constant, transform 1 swap shift into a more overflow check with open-coded fast case, transform bitand into fixnum-bitand in more cases 2009-07-16 23:50:48 -05:00
Slava Pestov e76dce8aff Overflowing fixnum intrinsics now expand into several CFG nodes. This speeds up the common case since only the uncommon case is now a stack syncpoint 2009-07-16 18:29:40 -05:00
Slava Pestov 9ad9600764 Remove %dispatch-label since its tehe same on all platforms; fix %gc on PowerPC 2009-06-07 21:46:28 -05:00
Slava Pestov 2d231f066a GC checks now save and restore registers 2009-06-02 18:23:47 -05:00
Slava Pestov b389dcf441 Redo compiler.codegen.fixup and get %dispatch to work 2009-06-01 02:32:36 -05:00
Slava Pestov fc152ef210 Various improvements aimed at getting local optimization regressions fixed:
- Rename _gc to ##gc
- Absolute labels are now supported
- Generate _dispatch-label
2009-05-31 23:28:08 -05:00
Slava Pestov 76d74c16af Fixing various bugs; alias analysis wasn't handling ##phi nodes, stack analysis incorrectly handled height-changing back edges and ##fixnum-*, clean up ##dispatch generation 2009-05-29 01:39:14 -05:00
Slava Pestov c93d876075 Better separation of concerns: cpu.{x86,ppc}.assembler no longer depends on compiler.codegen.fixup and cpu.architecture. Rename rt-xt-direct to rt-xt-pic to better explain its purpose 2009-05-06 16:14:53 -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
Slava Pestov a56d480aa6 Various optimizations leading to a 10% speedup on compiling empty EBNF parser:

- 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 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 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 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
