fix(clif-backend) Module::new does not use its argument.
...
The `Module::new` method requires an argument (`wasm: &[u8]`) that is
never used.
This patch removes the argument, and updates the code accordingly.

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.

Turns out we can just throw an exception from the signal handler

without any fancy tricks.

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

2019-03-02 14:16:02 -08:00
9a90689b93
Add preliminary support for throwing and catching uncatchable exceptions.
...
Additional info:
- WebAssembly "traps" are uncatchable, but are still caught by the trampoline caller.

- 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).
