dc5c6dd10a Always put allocas at the beginning of the entry block. 
Fixes a bug where we allocated stck space for struct return in every call of a function in a loop.

ce543fd4ed NFC. Don't re-lookup frame. It can't have changed, simply reorder operations. 2020-06-06 21:02:10 -07:00

b2c0ef4f95 NFC. Use const_zero() method or free function instead of const_int(0) and const_float(0.0). 2020-06-06 21:02:10 -07:00

1990e83ca9 Add two new functions to abi.rs, is_sret and pack_values_for_register_return. 
Pull the implementations out of wasm.rs and code.rs respectively, and simplify them.

7bdd387474 Use blocktype_params_results in lieu of blocktype_to_types. 
Remove read_info.rs entirely.

Add `to_compile_error` that converts a WasmResult into a Result<_, CompileError>, use it with `wptype_to_type`. This is a candidate for being moved into shared code.

Many functions had to change to deal with propagating CompileError.

04f2db1b82 Export wptype_to_type from wasmer_compiler. 
Also fix up its error message when it fails.

Use it in compiler-llvm and remove one of compiler-llvm's copies of this function.

f39a38779b Update function prologue, epilogue and CFG instructions. 
The function prologue now skips the sret argument if there is one.

The function epilogue packs values before return.

Br/BrIf/BrTable/Block/Loop/If/Else/End are updated to support multiple values.
As part of this, `read_info::blocktype_to_type` is removed. `blocktype_to_types` and `blocktype_to_param_types` take its place.

CtxType::func is updated to cache and return attributes. The allows the caller to place 'sret' on the call site, even though it's present on the FunctionValue. This helps some utility functions that check the callsite for presence of sret.

83195a1498 Use abi::func_type_to_llvm when producing an LLVM function type from wasm types. 
This renames `func_sig_to_llvm` to `func_type_to_llvm` and deletes the old version in intrinsics::. The new version returns a list of attributes along with the type. Update callers to set these attributes on the function or call site.
