* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8
* [HIP] Support early finalization of device code for -fno-gpu-rdcYaxun Liu2018-10-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch renames -f{no-}cuda-rdc to -f{no-}gpu-rdc and keeps the original options as aliases. When -fgpu-rdc is off, clang will assume the device code in each translation unit does not call external functions except those in the device library, therefore it is possible to compile the device code in each translation unit to self-contained kernels and embed them in the host object, so that the host object behaves like usual host object which can be linked by lld. The benefits of this feature is: 1. allow users to create static libraries which can be linked by host linker; 2. amortized device code linking time. This patch modifies HIP action builder to insert actions for linking device code and generating HIP fatbin, and pass HIP fatbin to host backend action. It extracts code for constructing command for generating HIP fatbin as a function so that it can be reused by early finalization. It also modifies codegen of HIP host constructor functions to embed the device fatbin when it is available.

* Unrevert r280035 now that the clang-cl bug it exposed has been fixed byRichard Smith2016-08-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r280133. Original commit message: C++ Modules TS: driver support for building modules. This works as follows: we add --precompile to the existing gamut of options for specifying how far to go when compiling an input (-E, -c, -S, etc.). This flag specifies that an input is taken to the precompilation step and no further, and this can be specified when building a .pcm from a module interface or when building a .pch from a header file. The .cppm extension (and some related extensions) are implicitly recognized as C++ module interface files. If --precompile is /not/ specified, the file is compiled (via a .pcm) to a .o file containing the code for the module (and then potentially also assembled and linked, if -S, -c, etc. are not specified). We do not yet suppress the emission of object code for other users of the module interface, so for now this will only work if everything in the .cppm file has vague linkage. As with the existing support for module-map modules, prebuilt modules can be provided as compiler inputs either via the -fmodule-file= command-line argument or via files named ModuleName.pcm in one of the directories specified via -fprebuilt-module-path=. This also exposes the -fmodules-ts cc1 flag in the driver. This is still experimental, and in particular, the concrete syntax is subject to change as the Modules TS evolves in the C++ committee. Unlike -fmodules, this flag does not enable support for implicitly loading module maps nor building modules via the module cache, but those features can be turned on separately and used in conjunction with the Modules TS support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@280134 91177308-0d34-0410-b5e6-96231b3b80d8

* [CUDA] Invoke ptxas and fatbinary during compilation.Justin Lebar2016-01-141-0/+1
| | | | | | | | | | | | | | | | | | | | Summary: Previously we compiled CUDA device code to PTX assembly and embedded that asm as text in our host binary. Now we compile to PTX assembly and then invoke ptxas to assemble the PTX into a cubin file. We gather the ptx and cubin files for each of our --cuda-gpu-archs and combine them using fatbinary, and then embed that into the host binary. Adds two new command-line flags, -Xcuda_ptxas and -Xcuda_fatbinary, which pass args down to the external tools.

NOTE: reverts r242077 to reinstate r242058, r242065, 242067 and includes fix for OS X test failures. - Changed driver pipeline to compile host and device side of CUDA files and incorporate results of device-side compilation into host object file. - Added a test for cuda pipeline creation in clang driver. New clang options: --cuda-host-only - Do host-side compilation only. --cuda-device-only - Do device-side compilation only. --cuda-gpu-arch=<ARCH> - specify GPU architecture for device-side compilation. E.g. sm_35, sm_30. Default is sm_20. May be used more than once in which case one device-compilation will be done per unique specified GPU architecture.

* Driver: Support invoking Clang on .ll or .bc inputs.Daniel Dunbar2010-06-071-2/+7
| | | | | | | | | | | | | | | - We actually pretend that we have two separate types for LLVM assembly/bitcode because we need to use the standard suffixes with LTO ('clang -O4 -c t.c' should generate 't.o'). It is now possible to do something like: $ clang -emit-llvm -S t.c -o t.ll ... assorted other compile flags ... $ clang -c t.ll -o t.o ... assorted other compile flags ... and expect that the output will be almost* identical to: $ clang -c t.c -o t.o ... assorted other compile flags ... because all the target settings (default CPU, target features, etc.) will all be initialized properly by the driver/frontend. *: This isn't perfect yet, because in practice we will end up running the optimization passes twice. It's possible to get something equivalent out with a well placed -mllvm -disable-llvm-optzns, but I'm still thinking about the cleanest way to solve this problem more generally. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105584 91177308-0d34-0410-b5e6-96231b3b80d8
