* AMDGPU: Fix names for generation featuresMatt Arsenault2019-04-031-2/+3
| | | | | | | | We should overall stop using these, but the uppercase name didn't work. Any feature string is converted to lowercase, so these could never be found in the table. llvm-svn: 357541
* AMDGPU: Remove dx10-clamp from subtarget featuresMatt Arsenault2019-03-291-6/+0
| | | | | | | | | | | | | | | | | | Since this can be set with s_setreg*, it should not be a subtarget property. Set a default based on the calling convention, and Introduce a new amdgpu-dx10-clamp attribute to override this if desired. Also introduce a new amdgpu-ieee attribute to match. The values need to match to allow inlining. I think it is OK for the caller's dx10-clamp attribute to override the callee, but there doesn't appear to be the infrastructure to do this currently without definining the attribute in the generic Attributes.td. Eventually the calling convention lowering will need to insert a mode switch somewhere for these. llvm-svn: 357302
* 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. llvm-svn: 351636
* AMDGPU: Allow fp32-denormals feature for r600 targetsJan Vesely2018-08-011-0/+9
| | | | | | | | This was accidentally removed in r335942. Differential Revision: https://reviews.llvm.org/D49934 llvm-svn: 338569
* AMDGPU: Separate R600 and GCN TableGen filesTom Stellard2018-06-281-0/+60
Summary: We now have two sets of generated TableGen files, one for R600 and one for GCN, so each sub-target now has its own tables of instructions, registers, ISel patterns, etc. This should help reduce compile time since each sub-target now only has to consider information that is specific to itself. This will also help prevent the R600 sub-target from slowing down new features for GCN, like disassembler support, GlobalISel, etc. Reviewers: arsenm, nhaehnle, jvesely Reviewed By: arsenm Subscribers: MatzeB, kzhuravl, wdng, mgorny, yaxunl, dstuttard, tpr, t-tye, javed.absar, llvm-commits Differential Revision: https://reviews.llvm.org/D46365 llvm-svn: 335942
