51cf9dde05 Move SSA value caches to the entry block. 
The supporting framework around LLVM will make sure to only compute values once if they
are known to never change. Previously, these values were attempted to be reused from places where
the users may not dominate the creation of the value. To avoid that, they are always created
in the entry block now.

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.

9cfda6800f Try to return an error from call_protected when an exception occurs. 
Something breaks pretty drastically sometimes, not sure why.

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.

57bfa9b0a4 Remove multiple throwing functions, just use one. 2019-03-02 14:16:02 -08:00
Lachlan Sneff
9a90689b93 Add preliminary support for throwing and catching uncatchable exceptions. 
Additional info:
- WebAssembly "traps" are uncatchable, but are still caught by the trampoline caller.

5760f6006a Start implementing exception handling by adding frame descriptor entry processing. 
- Soon, we should be able basic exceptions.

87ddf4f855 Add personality function. 
- This is part of supporting exceptions in the future.

a6fc06c908 Fix more compiling issues 
Specifically:
- Don't truncate the list of local parameters.
- If the default destination in a br_table instruction is a loop, don't pop any results.

f0ac76517a Start running spectests 
Additional info:
- Execution is turned off, this is just to make sure the backend can compile the entire specsuite.
- That being said, trampolines are implemented and protected call works (just doesn't protect).
