2077fb448a Fix C API table/global/memory imports 2019-03-02 22:28:00 -06:00

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.

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.

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).

fix appveyor installer and build (#224) 
* remove exception handler when function returns or throws

* revert to only reserving and not committing memory due to issues

* appveyor builds for release, caches more, only publish artifact once

Remove debug option from run command. 
I was looking into the code and I noticed that this option is not used.
The `debug!` macro is used across the codebase, which looks more ideal.

bugfix: Replace echo with printf so "\n" renders. 
notes:
  I could have used the -e flag in echo, however other lines
  nearby use printf so I figured it would be smart to stay consistent.

  Also, I see the usage of `command printf`. Not 100% if this is
  necessary. I don't see why printf would be redefined in the shell.
  If we're doing this, then we might as well prefix every call
  to a builtin or binary with `command` _just to be safe_.
