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if an aging GC is triggered while uninitialized code blocks are in the code heap, the code heap remembered set becomes out of date, resulting in code blocks pointing at invalid data 2009-12-22 15:49:21 +13:00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

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
