Lachlan Sneff	e362b56b07	Turns out we can just throw an exception from the signal handler ... without any fancy tricks. This has been tested on macos, hopefully it works on linux too.	2019-03-03 02:15:53 -08:00
Lachlan Sneff	9cfda6800f	Try to return an error from call_protected when an exception occurs. ... Something breaks pretty drastically sometimes, not sure why.	2019-03-02 19:08:15 -08:00
Lachlan Sneff	caf2205936	Add a signal handler for macos and linux. ... Implementation Notes: - To avoid setjmp, longjmp, and the mess that those create, we instead set the interrupting context of the signal handler to return into the `throw_trap` routine. To my surprise, this actually works. The stack ends up getting unwound normally and the memory-oob error is caught by the trampoline.	2019-03-02 17:00:05 -08:00
Lachlan Sneff	5760f6006a	Start implementing exception handling by adding frame descriptor entry processing. ... - Soon, we should be able basic exceptions.	2019-03-02 10:56:02 -08:00
Lachlan Sneff	5d77769381	Hopefully finish the memory manager implementation for llvm RuntimeDyLd	2019-02-27 17:21:20 -08:00
