Joe Groff d6227c182b vm: pack frame size into code block header bits 2011-12-14 09:56:45 -08:00
Joe Groff e21f316583 vm: store stack frame size in code blocks
Change modify-code-heap primitive so it takes a sixth element in each array for the frame size.

Joe Groff 0a1a252cdb vm: replace assert with FACTOR_ASSERT
Factor is finally a real C++ project and has a custom assert macro. Assertion failures were still getting caught as exceptions and causing failure loops. Write our own macro that calls factor::abort on failure.

Joe Groff 2705fc67cb vm: keep a set of all code_blocks in the code_heap
This way looking up code blocks by return address is an O(log n) set lookup rather than an O(n) linear scan.

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 bbe369ebfa Fix undefined-symbol reporting on 32-bit architectures; the return address is exactly at the relocation point in this case 2011-09-13 20:43:07 -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 d70cf197f2 vm: fix compile error 2010-04-04 13:53:17 -05:00
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- boot.x86.32.image has now been replaced by boot.winnt-x86.32.image and boot.unix-x86.32.image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 11ddbc03a4 vm: signal handling cleanup 2010-03-27 07:33:28 -04:00
Slava Pestov 69bb81dab8 vm: clean up TLS usage 2010-03-27 03:44:40 -04:00
Slava Pestov 3259ef4bec vm: modify-code-heap primitive now takes a pair of parameters, update-existing? and reset-pics?. If no generic words were changed, PICs do not need to be reset. If no existing words were redefined, the code heap doesn't have to be traced at all. Speeds up compilation of PEGs since those create lots of compilation units 2010-02-03 23:11:28 +13:00
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 e4da687413 vm: Tweak Factor VM to compile with Microsoft Visual Studio on Windows, in addition to Mingw. Add an Nmakefile which can be used for this purpose. Rename Makefile to GNUmakefile. 2010-01-17 03:43:22 +13:00
Slava Pestov c04fef10c7 vm: ensure that non-optimized calls to generic words which have not yet been compiled can still work 2010-01-06 23:49:14 +13:00
Slava Pestov febccd5f62 vm: if an aging GC is triggered while uninitialized code blocks are in the code heap, the code heap remembered set becomes out of date, resulting in code blocks pointing at invalid data 2009-12-22 15:49:21 +13:00
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
2009-12-15 07:20:09 -05:00
Slava Pestov 066d2836ca Get modify-code-heap working if stack traces are stripped (but then it won't update existing code blocks), and rename code_heap::code_heap_free() to code_heap::free() 2009-12-02 05:27:48 -06:00
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 d49c86ba11 vm: Clean up more code duplication and rename a few methods 2009-12-02 01:17:30 -06:00
Slava Pestov d664507b36 vm: factor out common code between image loading and initial code block relocation 2009-12-02 00:54:16 -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
