Alex Crichton	cf738b0d36	Attempt to fix tests on master (#662) ... * Attempt to fix tests on master * Make all doctests use items from the real `std` rather than this crate, it's just easier * Handle debuginfo weirdness by flagging functions as `no_mangle` that we're looking for instructions within. * Handle double undescores in symbol names	2019-01-30 15:11:35 -08:00

Alex Crichton	cb921381c4	Rewrite simd128 and wasm support (#620) ... * Update representation of `v128` * Rename everything with new naming convention of underscores and no modules/impls * Remove no longer necessary `wasm_simd128` feature * Remove `#[target_feature]` attributes (use `#[cfg]` instead) * Update `assert_instr` tests * Update some implementations as LLVM has evolved * Allow some more esoteric syntax in `#[assert_instr]` * Adjust the safety of APIs where appropriate * Remove macros in favor of hand-coded implementations * Comment out the tests for now as there's no known runtime for these yet	2018-12-13 20:17:30 -06:00
Alex Crichton	5a45175fe1	Run rustfmt on stable, delete rustfmt.toml (#619) ... This commit switches CI to running `rustfmt` on the stable compiler (as rustfmt is stable now!). Additionally it deletes `rustfmt.toml` to ensure we're following the same style as the rest of the ecosystem.	2018-12-13 17:26:22 -06:00

gnzlbg	3daebfbc0b	Add wasm32 simd128 intrinsics (#549) ... * Add wasm32 simd128 intrinsics * test wasm32 simd128 instructions * Run wasm tests like all other tests * use modules instead of types to access wasm simd128 interpretations * generate docs for wasm32-unknown-unknown * fix typo * Enable #[assert_instr] on wasm32 * Shell out to Node's `execSync` to execute `wasm2wat` over our wasm file * Parse the wasm file line-by-line, looking for various function markers and such * Use the `elem` section to build a function pointer table, allowing us to map exactly from function pointer to a function * Avoid losing debug info (the names section) in release mode by stripping `--strip-debug` from `rust-lld`. * remove exclude list from Cargo.toml * fix assert_instr for non-wasm targets * re-format assert-instr changes * add crate that uses assert_instr * Fix instructions having extra quotes * Add assert_instr for wasm memory intrinsics * Remove hacks for git wasm-bindgen * add wasm_simd128 feature * make wasm32 build correctly * run simd128 tests on ci * remove wasm-assert-instr-tests	2018-08-15 09:20:33 -07:00

Alex Crichton	f3cb25b8f9	Fix compile on latest nightly (#527) ... The `proc_macro` feature has stabilized in the compiler and usage of it largely needs to switch to `use_extern_macros` now.	2018-07-17 09:30:18 -05:00

gnzlbg	8ea9bc53f1	Initial PowerPC altivec and VSX support (#447) ... * add some powerpc/powerpc64 altivec/vsx intrinsics * temporarily make IntoBits/FromBits inline(always) * include powerpc64 module; use inline(always) from/into_bits only on powerpc	2018-05-16 12:10:19 -05:00

gnzlbg	30962e58e6	fix errors/warnings from the stabilization of cfg_target_feature and target_feature (#432) ... * fix build after stabilization of cfg_target_feature and target_feature * fix doc tests * fix spurious unused_attributes warning * fix more unused attribute warnings * More unnecessary target features * Remove no longer needed trait imports * Remove fixed upstream workarounds * Fix parsing the #[assert_instr] macro Following upstream proc_macro changes * Fix form and parsing of #[simd_test] * Don't use Cargo features for testing modes Instead use RUSTFLAGS with `--cfg`. This'll help us be compatible with the latest Cargo where a tweak to workspaces and features made the previous invocations we had invalid. * Don't thread RUSTFLAGS through docker * Re-gate on x86 verification Closes #411	2018-04-26 21:54:15 -05:00

Alex Crichton	39b5ec91ae	Reorganize and refactor source tree (#324) ... With RFC 2325 looking close to being accepted, I took a crack at reorganizing this repository to being more amenable for inclusion in libstd/libcore. My current plan is to add stdsimd as a submodule in rust-lang/rust and then use `#[path]` to include the modules directly into libstd/libcore. Before this commit, however, the source code of coresimd/stdsimd themselves were not quite ready for this. Imports wouldn't compile for one reason or another, and the organization was also different than the RFC itself! In addition to moving a lot of files around, this commit has the following major changes: * The `cfg_feature_enabled!` macro is now renamed to `is_target_feature_detected!` * The `vendor` module is now called `arch`. * Under the `arch` module is a suite of modules like `x86`, `x86_64`, etc. One per `cfg!(target_arch)`. * The `is_target_feature_detected!` macro was removed from coresimd. Unfortunately libcore has no ability to export unstable macros, so for now all feature detection is canonicalized in stdsimd. The `coresimd` and `stdsimd` crates have been updated to the planned organization in RFC 2325 as well. The runtime bits saw the largest amount of refactoring, seeing a good deal of simplification without the core/std split.	2018-02-18 10:07:35 +09:00
