2020-06-09[AVR] Update ABI type classification logic to match the the AVR-Clang ABIDylan McKay-5/+31
This patch brings the AVR calling convention argument classification logic in line with AVR Clang's behaviour. AVR-Clang currently uses the `clang::DefaultABIInfo` ABI implementation. This calling convention promotes all aggregates to indirect, no matter their size. It is also unnecessary to perform any integer width extension for AVR as the minimum argument size matches the minimum describable size of abi::Primitive::Int - 8 bits. At some point in the future, an AVR-GCC compatible argument classification implementation should be adopted in both Clang and Rust.

2019-11-09Rollup merge of #66050 - smaeul:patch/powerpc-abi-2, r=eddybMazdak Farrokhzad-32/+11
Fix C aggregate-passing ABI on powerpc The existing code (which looks like it was copied from MIPS) passes aggregates by value in registers. This is wrong. According to the SVR4 powerpc psABI, all aggregates are passed indirectly. See #64259 for more discussion, which addresses the ABI for the special case of ZSTs (empty structs).

2019-10-16Upgrade Emscripten targets to use upstream LLVM backendThomas Lively-62/+77
- Compatible with Emscripten 1.38.46-upstream or later upstream. - Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the old incorrect wasm32 C call ABI with the correct one, preserving the old one as wasm32_bindgen_compat for wasm-bindgen compatibility. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649.

2019-10-04Upgrade Emscripten targets to use upstream LLVM backendThomas Lively-62/+29
- Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the incorrect wasm32 C call ABI with the old asmjs version, which is correct for both wasm32 and JS. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Temporarily makes Emscripten targets use panic=abort by default because supporting unwinding will require an LLVM patch.

Function signatures with the `variadic` member set are actually C-variadic functions. Make this a little more explicit by renaming the `variadic` boolean value, `c_variadic`.

2018-11-15Fix powerpc64 ELFv2 big-endian struct-passing ABISamuel Holland-17/+12
The requirements here are not "ELFv1" requirements, but big-endian requirements, as the extension or non-extension of the argument is necessary to put the argument in the correct half of the register. Parameter passing in the ELFv2 ABI needs these same transformations. Since this code makes no difference on little-endian machines, simplify it to use the same code path everywhere.
