b5d9b448ae Add support for libcalls as relocation targets. 2020-04-30 20:54:29 -07:00
Nick Lewycky
71eeb135bc Parse a relocation to a different user function out of the object file. 
This updates to a newer inkwell to pick up a fix to Section::get_contents. Picking that up changed builder.build_struct_gep to return a Result, and there's many API updates scattered around to support that.

Compute the function names for all local and imported functions in the module in advance and pass that mapping to the function code generation.

debug_trap is added to Intrinsics, though all users are commented out.

944c3d0f2f Fix trampoline generation. 
Updates to new API for trampolines, taking two vmctx pointers and reusing the input space to write the returns.

Wasm values are padded to 128-bits.

Removes a pile of dead code.

502e5badf4 Finish emitting and loading the trampoline code. 
Turning an LLVM module into a CompiledFunction should be refactored.

Bump to latest inkwell so that we can make use of object_file with the fixes.

Comment out accidentally committed debug code that writes to my home directory.

1de21f0c33 Make translator::intrinsics accessible to trampoline. 
Start filling in the code to generate trampolines. Move func_type_to_llvm and type_to_llvm from code.rs to intrinsics.rs so that trampoline code can reuse them.

a6bde15ce5 Connect trampoline code to trampoline module. Still unimplemented. 2020-04-24 16:31:31 -07:00
Nick Lewycky
474b3eb2f2 Fill in CompiledFunction::body with the instructions. 
Use a bit of a hack to find the function, we ask LLVM to emit it to a non-standard section with a name of our choosing, and that entire section should have our function body and nothing else.

8b7da22a1a Make vmctx an i8* so that we can use byte addressing. 
Implement dynamic_sigindex.

56fe08ad00 Assorted fixes: 
Fix creation of the target machine. Fix CPU features, architecture and target name.

Function names are not mandatory. Support unnamed functions.

Include parameters and local variables in the list of local variables for LLVMFunctionCodeGenerator.

Run the tests single-threaded, using a Mutex in the rayon code. This means that only the first error is real, subsequent errors are just picking up the panic across threads.

Add TODOs about attributes on vmctx.
