5744f6896f 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.

42c9bdf8c2 fix(clif-backend) Remove an unused variable declaration. 
The `compiled_functions` variable is declared twice. The first
declaration is never used. This patch removes it.

d9073c03c6 fix(runtime-core) hasher does not need to be mutable. 
This patch updates the `hasher` variable. It is declared as mutable,
but it's never mutated.

ec4e476cc6 fix(runtime-core) Remove an unused import.

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.
 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.

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.

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).

cb29261ec7 Use repr(transparent) for single element structs (#187) 
The ABI of aggregates such as single element structs is not required to
be the same as the single elements themselves. This is especially true
for f64 vs. #[repr(c)] struct F(f64); on Windows. Therefore the macro
has been tweaked so S1 uses repr(transparent) which is made for exactly
for this use case.
