* [NVPTX] Add preliminary intrinsics and codegen support for textures/surfacesJustin Holewinski2014-04-09
| | | | | | This commit adds intrinsics and codegen support for the surface read/write and texture read instructions that take an explicit sampler parameter. Codegen operates on image handles at the PTX level, but falls back to direct replacement of handles with kernel arguments if image handles are not enabled. Note that image handles are explicitly disabled for all target architectures in this change (to be enabled later). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205907 91177308-0d34-0410-b5e6-96231b3b80d8
* Optimize away unnecessary address casts.Eli Bendersky2014-04-03
| | | | | | | | | | | Removes unnecessary casts from non-generic address spaces to the generic address space for certain code patterns. Patch by Jingyue Wu. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205571 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix for PR19099 - NVPTX produces invalid symbol names.Eli Bendersky2014-03-31
| | | | | | | | | | This is a more thorough fix for the issue than r203483. An IR pass will run before NVPTX codegen to make sure there are no invalid symbol names that can't be consumed by the ptxas assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205212 91177308-0d34-0410-b5e6-96231b3b80d8
* Removes the NVPTXSplitBBatBar pass.Eli Bendersky2014-03-24
| | | | | | | | | This pass is a historic remnant and actually causes less efficient code to be generated in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204620 91177308-0d34-0410-b5e6-96231b3b80d8
* [CMake] Let add_public_tablegen_target() provide intrinsics_gen, too.NAKAMURA Takumi2013-11-28
| | | | | | | | | | I think, in principle, intrinsics_gen may be added explicitly. That said, it can be added incidentally, since each target already has dependencies to llvm-tblgen. Almost all source files depend on both CommonTaleGen and intrinsics_gen. Explicit add_dependencies() have been pruned under lib/Target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195929 91177308-0d34-0410-b5e6-96231b3b80d8
* [CMake] Let add_public_tablegen_target responsible to provide dependency to ↵NAKAMURA Takumi2013-11-28
| | | | | | | | | CommonTableGen. add_public_tablegen_target adds *CommonTableGen to LLVM_COMMON_DEPENDS. LLVM_COMMON_DEPENDS affects add_llvm_library (and other add_target stuff) within its scope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195927 91177308-0d34-0410-b5e6-96231b3b80d8
* [NVPTX] Start conversion to MC infrastructureJustin Holewinski2013-08-06
| | | | | | | | | This change converts the NVPTX target to use the MC infrastructure instead of directly emitting MachineInstr instances. This brings the target more up-to-date with LLVM TOT, and should fix PR15175 and PR15958 (libNVPTXInstPrinter is empty) as a side-effect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187798 91177308-0d34-0410-b5e6-96231b3b80d8
* Target/*/CMakeLists.txt: Add the dependency to CommonTableGen explicitly for ↵NAKAMURA Takumi2013-08-06
| | | | | | | | | each corresponding CodeGen. Without explicit dependencies, both per-file action and in-CommonTableGen action could run in parallel. It races to emit *.inc files simultaneously. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187780 91177308-0d34-0410-b5e6-96231b3b80d8
* [NVPTX] Re-enable support for virtual registers in the final outputJustin Holewinski2013-05-31
| | | | | | | | | | | | Now that 3.3 is branched, we are re-enabling virtual registers to help iron out bugs before the next release. Some of the post-RA passes do not play well with virtual registers, so we disable them for now. The needed functionality of the PrologEpilogInserter pass is copied to a new backend-specific NVPTXPrologEpilog pass. The test for this commit is not breaking the existing tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182998 91177308-0d34-0410-b5e6-96231b3b80d8
* [NVPTX] Add GenericToNVVM IR converter to better handle idiomatic LLVM IR inputsJustin Holewinski2013-05-20
| | | | | | | | | | | | | | | This converter currently only handles global variables in address space 0. For these variables, they are promoted to address space 1 (global memory), and all uses are updated to point to the result of a cvta.global instruction on the new variable. The motivation for this is address space 0 global variables are illegal since we cannot declare variables in the generic address space. Instead, we place the variables in address space 1 and explicitly convert the pointer to address space 0. This is primarily intended to help new users who expect to be able to place global variables in the default address space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182254 91177308-0d34-0410-b5e6-96231b3b80d8
* [NVPTX] Add NVVMReflect pass to allow compile-time selection ofJustin Holewinski2013-03-30
| | | | | | | | | | | | | | | | specific code paths. This allows us to write code like: if (__nvvm_reflect("FOO")) // Do something else // Do something else and compile into a library, then give "FOO" a value at kernel compile-time so the check becomes a no-op. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178416 91177308-0d34-0410-b5e6-96231b3b80d8
* [NVPTX] Disable vector registersJustin Holewinski2013-02-12
| | | | | | | | | | | Vectors were being manually scalarized by the backend. Instead, let the target-independent code do all of the work. The manual scalarization was from a time before good target-independent support for scalarization in LLVM. However, this forces us to specially-handle vector loads and stores, which we can turn into PTX instructions that produce/consume multiple operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174968 91177308-0d34-0410-b5e6-96231b3b80d8

* This patch adds a new NVPTX back-end to LLVM which supports code generation ↵Justin Holewinski2012-05-04
for NVIDIA PTX 3.0. This back-end will (eventually) replace the current PTX back-end, while maintaining compatibility with it. The new target machines are: nvptx (old ptx32) => 32-bit PTX nvptx64 (old ptx64) => 64-bit PTX The sources are based on the internal NVIDIA NVPTX back-end, and contain more functionality than the current PTX back-end currently provides.
