* [Builtins] Provide a mechanism to selectively disable tests based on whether ↵Dan Liew2019-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | an implementation is provided by a builtin library. Summary: If a platform removes some builtin implementations (e.g. via the Darwin-excludes mechanism) then this can lead to test failures because the test expects an implementation to be available. To solve this lit features are added for each configuration based on which sources are included in the builtin library. The features are of the form `librt_has_<name>` where `<name>` is the name of the source file with the file extension removed. This handles C and assembly sources. With the lit features in place it is possible to make certain tests require them. Example: ``` REQUIRES: librt_has_comparedf2 ``` All top-level tests in `test/builtins/Unit` (i.e. not under `arm`, `ppc`, and `riscv`) have been annotated with the appropriate `REQUIRES: librt_has_*` statement. rdar://problem/55520987 Reviewers: beanz, steven_wu, arphaman, dexonsmith, phosek, thakis Subscribers: mgorny, #sanitizers, llvm-commits Tags: #llvm, #sanitizers Differential Revision: https://reviews.llvm.org/D68064 llvm-svn: 375150

* [builtins] Rounding mode support for addxf3/subxf3Yi Kong2019-03-261-1/+22
| | | | | | | | | | | | | | | | | Implement rounding mode support for addxf3/subxf3. On architectures that implemented the support, this will access the corresponding floating point environment register to apply the correct rounding. For other architectures, it will keep the current behaviour and use IEEE-754 default rounding mode (to nearest, ties to even). ARM32/AArch64 support implemented in this change. i386 and AMD64 will be added in a follow up change. Differential Revision: https://reviews.llvm.org/D57143 llvm-svn: 357035
* Update more file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | | to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648
* [Builtin] Implement lit-test support (part 1 of 2: test cases update)Weiming Zhao2017-03-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Original r297566 is splitted into two parts. This is part one, which adds "RUN" command for test cases. Unit/arm/call_apsr.S is updated to support thumb1. It also fixes a bug in arm/aeabi_uldivmod_test.c gcc_personality_test is XFAILED as the framework cannot handle it so far. cpu_model_test is also XFAILED for now as it is expected to return non-zero. TODO: A few tests are XFAILed for armhf and aarch64. We need further investigating. [1,2] Tracks the issue.

* Add COMPILER_RT_ABI attribute to declarations of builtin functions in unittestsDerek Schuff2015-04-241-1/+2
| | | | | | | | | | | | | | Summary: This makes their local declarations match their definitions for ARM targets, where they have a different calling convention. This really only affects functions that use floating point types (since the runtime functions use soft-float, and some targets may default to hard-float) but it seemed good to make it uniform and do the int-only ones too.
