vm: reinitialize all_blocks from scratch after gc
...
Faster and more likely to be correct than trying to fixup the existing set

vm: initialize all_blocks map from image
...
um, code blocks from the image need to go in the set too
2011-11-23 11:11:26 -08:00
0d8cf08ea0
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.

Stop wearing monocle and use the term "entry point" instead of "XT" throughout VM and compiler; also remove two unused relocation types

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.

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

RT_HERE now takes its argument from the literal table rather than the parameter table, reducing image size further

Split literal table into literal and parameter tables, literal table is discarded after code block initialization

vm: update callback stub machine code at the end of compaction to prevent it from seeing an inconsistent data stack

2009-12-02 01:17:30 -06:00

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
2009-12-02 00:48:41 -06:00

vm: rename gc_root to data_root, add code_root to fix a problem where code blocks would move underneath the PIC compiler if PIC compiler allocated enough
2009-11-02 18:10:34 -06:00
