Alexander Iljin 0d57734dab vm: replace block comments /**/ with line comments // 2016-09-09 05:47:52 +02:00
Björn Lindqvist 0c9c0b2f82 VM: removes a few methods related to relocation handling
They are only used once, so it is simpler to "inline" them
2015-12-13 13:56:36 +01:00
Björn Lindqvist 46bfcbf3a2 VM: the rel_type() and rel_offset() accessors in instruction_operand can be removed 2015-12-13 13:56:36 +01:00
Björn Lindqvist b3de115e3c VM: remove RT_EXCEPTION_HANDLER reference 2015-09-02 21:54:47 +02:00
Björn Lindqvist 22887c5816 VM: get rid of the odd RT_EXCEPTION_HANDLER relocation
The address to the win32 relocation handler can be stored in a special
object and be accessed by jit-install-seh. Doing it that way is better
because you can remove a lot of special code related to that relocation
type.

Joe Groff e1465308cd vm: add RT_SAFEPOINT relocation type 2011-10-27 21:14:44 -07:00
Slava Pestov f8e475485a Add RT_INLINE_CACHE_MISS relocation type to avoid frequent dlsym lookups when compiling PICs. Fixes #123 2011-10-03 00:26:21 -07:00
Slava Pestov 7c3827190b Tease out symbol name and library in undefined_symbol() handler, for friendlier errors when calling an unresolved C function name. Fixes #93 2011-09-12 00:56:24 -07:00
Erik Charlebois 64252dbdbc 32 and 64 bit Linux PPC support 2011-05-23 23:36:14 -04:00
Slava Pestov 58e4381eb1 compiler: new "binary literal area" at the end of a word's machine code stores constant floats and SIMD vectors; this allows ##load-reference/##load-memory fusion to be performed on x86-64, with a RIP-relative address reaching the data; also simplifies VM since custom relocation types used by the previous 32-bit-only optimization are no longer needed 2010-05-03 17:34:35 -04:00
Slava Pestov 9788323d25 compiler: add ##load-vector instruction to avoid wasting a temporary register on x86-32 2010-05-03 17:34:28 -04:00
Slava Pestov 2517b2fc2b compiler: combine ##load-constant followed by ##alien-double into a ##load-double on x86-32, saving an integer register 2010-04-18 21:42:45 -05:00
Slava Pestov 1434a305c8 vm: add a new rc-absolute-1 relocation class to allow storing values in 8-bit operands, and optimized code sequences for inline caches using this 2010-04-12 14:22:41 -07:00
Slava Pestov 74640b7f71 Get green threads working on Windows
- store stack base and limit in TIB
- set up a frame-based structured exception handler in each context's callstack
- boot.x86.32.image has now been replaced by boot.winnt-x86.32.image and boot.unix-x86.32.image

Slava Pestov 942f6e0943 Update Win64 support 2010-01-25 15:39:34 +13:00
Slava Pestov 5606825e8b vm: remove primitive table, non-optimizing compiler now looks up primitives with dlsym() 2010-01-19 20:00:33 +13:00
Slava Pestov 637a77c018 Stop wearing monocle and use the term "entry point" instead of "XT" throughout VM and compiler; also remove two unused relocation types 2010-01-18 20:54:00 +13:00
Slava Pestov ba5b90e063 Change how non-volatile register preservation is done in alien callbacks, with the aim of fixing callbacks on PowerPC, and to eventually eliminate assembly code from VM
- Simplify calculation of offset in relocation table
- Open-code %alien-callback
- Remove magic_frame hack from context objects
- Move magical return instruction from optimizing compiler backend into callback entry stub

Slava Pestov 0068bce934 vm: big overhaul of non-optimizing compiler
- change some primitives into sub-primitives: fixnum+ fixnum- fixnum* inline-cache-miss inline-cache-miss-tail
- rename some relocation types for clarity
- some other minor re-organizations and cleanups

Slava Pestov 514043eb14 vm: fix instruction_operand::load_value() for PowerPC relocation classes 2009-12-02 09:20:33 -05:00
Slava Pestov eb840dcf41 RT_HERE now takes its argument from the literal table rather than the parameter table, reducing image size further 2009-12-02 04:55:48 -06:00
Slava Pestov 68c09f0e93 Split literal table into literal and parameter tables, literal table is discarded after code block initialization 2009-12-02 04:28:15 -06:00
Slava Pestov c6602bda27 Big cleanup of literal table and relocation-related code
- new way to iterate over instruction_operands cleans up relocation code
- move some methods out of the VM class to clean up code
- if debugging is on, die earlier if attempting to allocate inside GC
- callback heap entries are now code_blocks
- replace block_granularity with data_alignment
