* AMDGPU: Force inlining if LDS global address is usedMatt Arsenault2018-07-091-0/+1
| | | | | | | | | | These won't work for the forseeable future. These aren't allowed from OpenCL, but IPO optimizations can make them appear. Also directly set the attributes on functions, regardless of the linkage rather than cloning functions like before. llvm-svn: 336587
* AMDGPU: Separate R600 and GCN TableGen filesTom Stellard2018-06-281-7/+7
| | | | | | | | | | | | | | | | | | | | | 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

* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-011-1/+1
| | | | | | | | | | | | | | | | We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* (Re-landing) Expose a TargetMachine::getTargetTransformInfo functionSanjoy Das2017-12-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-land r321234. It had to be reverted because it broke the shared library build. The shared library build broke because there was a missing LLVMBuild dependency from lib/Passes (which calls TargetMachine::getTargetIRAnalysis) to lib/Target. As far as I can tell, this problem was always there but was somehow masked before (perhaps because TargetMachine::getTargetIRAnalysis was a virtual function). Original commit message: This makes the TargetMachine interface a bit simpler. We still need the std::function in TargetIRAnalysis to avoid having to add a dependency from Analysis to Target. See discussion: http://lists.llvm.org/pipermail/llvm-dev/2017-December/119749.html I avoided adding all of the backend owners to this review since the change is simple, but let me know if you feel differently about this.

* TargetMachine: Merge TargetMachine and LLVMTargetMachineMatthias Braun2017-10-121-1/+1
| | | | | | | | | | | | | | | Merge LLVMTargetMachine into TargetMachine. - There is no in-tree target anymore that just implements TargetMachine but not LLVMTargetMachine. - It should still be possible to stub out all the various functions in case a target does not want to use lib/CodeGen - This simplifies the code and avoids methods ending up in the wrong interface.

* Delete Default and JITDefault code modelsRafael Espindola2017-08-031-5/+5
| | | | | | | | | | | | | | | IMHO it is an antipattern to have a enum value that is Default. At any given piece of code it is not clear if we have to handle Default or if has already been mapped to a concrete value. In this case in particular, only the target can do the mapping and it is nice to make sure it is always done. This deletes the two default enum values of CodeModel and uses an explicit Optional<CodeModel> when it is possible that it is unspecified. llvm-svn: 309911
* AMDGPU: Initial implementation of callsMatt Arsenault2017-08-011-0/+3

* TargetMachine: Indicate whether machine verifier passes.Matthias Braun2017-05-311-1/+4
| | | | | | | | | | | | | This adds a callback to the LLVMTargetMachine that lets target indicate that they do not pass the machine verifier checks in all cases yet. This is intended to be a temporary measure while the targets are fixed allowing us to enable the machine verifier by default with EXPENSIVE_CHECKS enabled!

* [AMDGPU] Get address space mapping by target triple environmentYaxun Liu2017-03-271-6/+6
| | | | | | | | | | | | | | | | | | As we introduced target triple environment amdgiz and amdgizcl, the address space values are no longer enums. We have to decide the value by target triple. The basic idea is to use struct AMDGPUAS to represent address space values. For address space values which are not depend on target triple, use static const members, so that they don't occupy extra memory space and is equivalent to a compile time constant. Since the struct is lightweight and cheap, it can be created on the fly at the point of usage. Or it can be added as member to a pass and created at the beginning of the run* function.

* [AMDGPU] Lower null pointers in static variable initializerYaxun Liu2017-02-071-0/+12
| | | | | | | | | | | | For amdgcn target Clang generates addrspacecast to represent null pointers in private and local address spaces. In LLVM codegen, the static variable initializer is lowered by virtual function AsmPrinter::lowerConstant which is target generic. Since addrspacecast is target specific, AsmPrinter::lowerConst This patch overrides AsmPrinter::lowerConstant with AMDGPUAsmPrinter::lowerConstant, which is able to lower the target-specific addrspacecast in the null pointer representation so that -1 is co Differential Revision: https://reviews.llvm.org/D29284 llvm-svn: 294265

| | | | | | | | | | | | | | This change introduces adjustPassManager target callback giving a target an opportunity to tweak PassManagerBuilder before pass managers are populated.

* [AMDGPU] Add amdgpu-unify-metadata passStanislav Mekhanoshin2016-12-081-0/+1
| | | | | | | | | | | | | | | | | | Multiple metadata values for records such as opencl.ocl.version, llvm.ident and similar are created after linking several modules. For some of them, notably opencl.ocl.version, this creates semantic problem because we cannot tell which version of OpenCL the composite module conforms. Moreover, such repetitions of identical values often create a huge list of unneeded metadata, which grows bitcode size both in memory and stored on disk. It can go up to several Mb when linked against our OpenCL library. Lastly, such long lists obscure reading of dumped IR. The pass unifies metadata after linking.

| | | | | | | | | Split AMDGPUSubtarget into amdgcn/r600 specific subclasses. This removes most of the static_casting of the basic codegen classes everywhere, and tries to restrict the features visible on the wrong target. llvm-svn: 273652
* Delete Reloc::Default.Rafael Espindola2016-05-181-6/+9
| | | | | | | | | | | | Having an enum member named Default is quite confusing: Is it distinct from the others?
