* Use `GNUInstallDirs` to support custom installation dirs. -- LLVMJohn Ericson2021-11-021-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new draft of D28234. I previously did the unorthodox thing of pushing to it when I wasn't the original author, but since this version - Uses `GNUInstallDirs`, rather than mimics it, as the original author was hesitant to do but others requested. - Is much broader, effecting many more projects than LLVM itself. I figured it was time to make a new revision. I am using this patch (and many back-ports) as the basis of https://github.com/NixOS/nixpkgs/pull/111487 for my distro (NixOS). It looked like people were generally on board in D28234, but I make note of this here in case extra motivation is useful. --- As pointed out in the original issue, a central tension is that LLVM already has some partial support for these sorts of things. For example `LLVM_LIBDIR_SUFFIX`, or `COMPILER_RT_INSTALL_PATH`. Because it's not quite clear yet what to do about those, we are holding off on changing libdirs and `compiler-rt`. for this initial PR. --- On the advice of @lebedev.ri, I am splitting this up a bit per subproject, starting with LLVM. To allow it to be more easily reviewed. This and the subsequent patch must be landed together, as this will not build alone. But the rest can be landed on their own.

* libclc: Fix rounding during type conversionDaniel Stone2021-08-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The rounding during type conversion uses multiple conversions, selecting between them to try to discover if rounding occurred. This appears to not have been tested, since it would generate code of the form: float convert_float_rtp(char x) { float r = convert_float(x); char y = convert_char(y); [...] } which will access uninitialised data. The idea appears to have been to have done a char -> float -> char roundtrip in order to discover the rounding, so do this. Discovered by inspection.

* libclc: Add clspv target to libclcAlan Baker2021-03-046-2/+352
| | | | | | | | | | | | | | | Add clspv as a new target for libclc. clspv is an open-source compiler that compiles OpenCL C to Vulkan SPIR-V. Compiles for the spir target. The clspv target differs from the the spirv target in the following ways: * fma is modified to use uint2 instead of ulong for mantissas. This results in lower performance fma, but provides a implementation that can be used on more Vulkan devices where 64-bit integer support is less common. * Use of a software implementation of nextafter because the generic implementation depends on nextafter being a defined builtin function for which clspv has no definition. * Full optimization of the library (-O3) and no conversion to SPIR-V This library is close to what would be produced by running opt -O3 < builtins.opt.spirv-mesa3d-.bc > builtins.opt.clspv--.bc and continuing the build from that point.

* libclc: Use find_package to find Python 3 and require itAaron Puchert2020-10-012-4/+2
| | | | | | | | | | | | | | | | | | | The script's shebang wants Python 3, so we use FindPython3. The original code didn't work when an unversioned python was not available. This is explicitly allowed in PEP 394. ("Distributors may choose to set the behavior of the python command as follows: python2, python3, not provide python command, allow python to be configurable by an end user or a system administrator.") Also I think it's actually required, so let the configuration fail if we can't find it. Lastly remove the shebang, since the script is only run via interpreter and doesn't have the executable bit set anyway. Reviewed By: jvesely Differential Revision: https://reviews.llvm.org/D88366
