Joe Groff 55115d7971 vm: initialize all_blocks map from image
um, code blocks from the image need to go in the set too

Joe Groff 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.

Joe Groff 5b43301eb6 vm: strip out call-counting profiler
This makes the separate "code" and "entry_point" fields in word and quotation redundant, so also remove them to reclaim an additional cell per word and quotation object, which should help with #318.

Joe Groff 011ce33068 vm: Revert extra canary page before callstack
This reverts commit 7d5c8d6990385b94569116a23163d7e75ae21f49. We pretty much can't avoid unwinding frames without some more drastic redesign.

Joe Groff ed72d57c1a vm: allocate an extra canary page before callstack
This will let us safely unguard the callstack overflow guard page as a grace page so the callstack overflow handler can do its business without discarding frames.

Slava Pestov 1f2f72de5e vm: implement frame-based SEH for 64-bit Windows 2010-04-08 10:32:14 -07:00
Slava Pestov 310399995e Add code heap introspection primitive to VM, and make a code-blocks word in tools.memory that wraps a useful interface around this. Add a lookup-return-address word and use this in tools.disassembler.utils 2010-02-03 23:11:32 +13:00
Slava Pestov d19709c188 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 0165daf56c 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 a942e2c34d 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 5180f80180 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 912b1265fc 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 ca7bca6738 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 e2beabf2be vm: new GC policy: mark sweep after N megabytes promoted, mark compact if tenured space cannot fit nursery+aging in one contiguous block. N = 32 on 32-bit and 64 on 64-bit 2009-10-30 02:26:57 -05:00
