Slava Pestov 63edd20a55 vm: eliminating register variables work in progress. Works on x86-32 with non-optimizing compiler 2009-12-19 10:59:56 +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 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 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

Slava Pestov 884ac79423 vm: minor tweaks which reduce image size by ~300kb 2009-10-06 01:31:39 -05:00
Slava Pestov c4ef640f4d Big VM cleanup
- Move forward declarations of 'struct factor_vm' to one place
- Rename template parameters from T and TYPE to descriptive names. New convention: CamelCase for template parameters
- Change some higher-order functions taking function pointers into templates, and define classes overriding operator(). There's a bit of new boilerplate here but its more consistent than the old mish-mash approaches
- Put GC state into a gc_state struct
- Use exceptions instead of longjmp for non-local control transfer in GC
- In code GC, instead of interleaving code block tracing with copying, add code blocks which need to be revisited to an std::set stored in the gc_state
