2020-11-09Move from an "asm" flag to a "no-asm" feature flag (#386)Joseph Richey-4/+4
* Use a no-asm feature instead of an asm feature This works better as core/alloc/std have trouble supporting default featues in this crate. Signed-off-by: Joe Richey <joerichey@google.com> * Have no-asm disable arm assembly intrinsics Signed-off-by: Joe Richey <joerichey@google.com>

2020-05-29Expand wasm32 testing on CI (#360)Alex Crichton-4/+12
* Expand wasm32 testing on CI Run the full `run.sh` test script to get full assertions, including that nothing in the wasm compiler-builtins is panicking. Unfortunately it's currently panicking, so this is good to weed out! * Update libm
2020-04-29Switch to using `llvm_asm!` instead of `asm!` (#351)Alex Crichton-2/+4
* Switch to using `llvm_asm!` instead of `asm!` * Run rustfmt * Fix how LTO is specified on nightly

2019-05-16Remove `compiler-rt` submodule from this repositoryAlex Crichton-6/+8
This commit removes the `compiler-rt` submodule from this repository. The goal here is to align the `compiler-rt` used for compiling C intrinsics with the upstream rust-lang/rust's usage of `llvm-project`. Currently we have both an `llvm-project` repository as well as `compiler-rt`, but they can naturally get out of sync and it's just one more submodule to manage. The thinking here is that the feature `c` for this crate, when activated, will require the user to configure where the source code for `compiler-rt` is present. This places the onus on the builder of `compiler-builtins` to check-out and arrange for the appropriate `compiler-rt` source code to be placed somewhere. For rust-lang/rust this is already done with the `llvm-project` submodule, and we can arrange for it to happen on this crate's CI anyway. For users of this crate this is a bit of a bummer, but `c` is disabled by default anyway and it seems unlikely that `c` is explicitly opted in to all that much. (given the purpose of this crate) This should allow us to archive the `compiler-rt` repository and simply use `llvm-project` in the rust-lang/rust repository.
2019-05-15Remove the need for #[cfg] in #[use_c_shim_if]Alex Crichton-0/+1
This commit tweaks the implementation of the synthetic `#[use_c_shim_if]` attribute, renaming it to `#[maybe_use_optimized_c_shim]` in the process. This no longer requires specifying a `#[cfg]` clause indicating when the optimized intrinsic should be used, but rather this is inferred and printed from the build script. The build script will now print out appropriate `#[cfg]` directives for rustc to indicate what intrinsics it's compiling. This should remove the need for us to keep the build script and the source in sync, but rather the build script can simply take care of everything.
2019-05-14Fix __divsi3 and __udivsi3 on thumbv6m targetsAlex Crichton-79/+40
This commit fixes a bug accidentally introduced in #285 where some lingering references remained to `#[cfg(thumbv6m)]` but this, since the historical revert, was renamed to `#[cfg(thumb_1)]`. This caused on the thumbv6m platform for the intrinsics to be accidentally omitted because the build script didn't actually compile them but the Rust code thought the C code was in use. After correcting the `#[cfg]` statements the CI configuration for the `thumb*` family of targets was all updated. The support for xargo testing was removed from `run.sh` since it had long since bitrotted, and the script was updated to simply build the intrinsics example to attempt to link for each of these targets. This in turn exposed the bug locally and allowed to confirm a fix once the `#[cfg]` statements were corrected. cc rust-lang/rust#60782
2019-05-02Merge pull request #286 from alexcrichton/fix-dupeAlex Crichton-0/+9
Fix duplicate symbol __clzsi2
2019-05-02Fix duplicate symbol __clzsi2Alex Crichton-0/+9
Looks like our tests weren't quite testing compiler-builtins when it was compiled with unmangled symbols, so update the tests to catch this and then fix the compilation of the `__clzsi2` intrinsic to use the C version if it's compiled.
2019-05-02Revert "Use the Rust implementation of udivsi3 on ARM"Alex Crichton-0/+1

2018-02-25Remove no_std featuresPaolo Teti-4/+2
Everything default unconditionally to #![no_std].
2018-02-25Keep mangled-names as a default featurePaolo Teti-6/+8
2018-02-18Fix CI for thumb* targetsPaolo Teti-14/+15
Main fix is inside 'utest' all the rest are minor fixes due to the new 'testcrate'. Still allow failures on TravisCI for a while.
2018-01-31Simplify how testing is doneAlex Crichton-5/+5
All tests are moved to a separate crate in this repository to enable features by default. Additionally the test generation is moved to a seprate build script and simplified to reduce the amount of boilerplate needed per test. Overall this should still be testing everything, just in a different location!

2017-10-07drop binfmt_misc dependencyJorge Aparicio-1/+15
Instead use the Cargo runner feature. The binfmt_misc approach requires running a privileged container for setup. Not all docker setups support privileged containers so the test suite should be more accessible with this change as no privileged container is needed.

2017-06-24Tweak testing and such:Alex Crichton-8/+24
* Don't run `intrinsics` tests on thumb * Disable `compiler_builtins` attribute on `feature = "gen-tests"` * Disable mangling on `feature = "gen-tests"` instead of `cfg(test)`

2017-06-23Handle aeabi aliasingAlex Crichton-14/+16
Objects in compiler-rt may have two symbols, so this makes sure that we don't bring in those objects by accident by defining the aliases ourselves.
