This seems reasonable and failure to support this causes tricky to diagnose errors if one uses the extent of an input in an RDom that is then used in a memoized Func. The code pattern here is a bit heuristic in that I can't think of a case where a Var has a buffer but the reference isn't to a *field* of the buffer.

This cache is robust for kernels being used across multiple contexts and threads as well as using common code via a template. OpenGL and OpenGLCompute are not addressed due to issues in their implementation. There should be no regressions for those runtimes however. Adds tests for many GPU kernels and kernels across contexts and threads. Fixes a bug in CUDA runtime where some error message text in cuda_do_multidimensional_copy was not initialized.

The reason for this is that it's likely that there's an f[ramp(x, 2, 16)] nearby, and aligning down the x+1 to x means we can share the dense loads and just deinterleave. This PR does the same when there's no x, just an odd constant. This means that cases like f[ramp(64, 2, 16)] + f[ramp(65, 2, 16)] now generate much better assembly. In one case I have it speeds up an entire pipeline by 8%, because aligning the loads in this way causes them to all be promoted off the stack into registers. | 30 November 2020, 21:14:56 UTC |

| 6c754cf | Emil Melnikov | 20 November 2020, 19:53:34 UTC | Change "CMAKE_MODULE_PATH" to "CMAKE_PREFIX_PATH" (#5461) I tried to use instructions for a basic CMake project with a locally downloaded copy of Halide, and got the following error: ``` CMake Error at CMakeLists.txt:9 (find_package): By not providing "FindHalide.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Halide", but CMake did not find one. Could not find a package configuration file provided by "Halide" with any of the following names: HalideConfig.cmake halide-config.cmake Add the installation prefix of "Halide" to CMAKE_PREFIX_PATH or set "Halide_DIR" to a directory containing one of the above files. If "Halide" provides a separate development package or SDK, be sure it has been installed. ``` Changing `CMAKE_MODULE_PATH` to `CMAKE_PREFIX_PATH` worked for me. | 20 November 2020, 19:53:34 UTC |

| d5e425e | Pranav Bhandarkar | 28 October 2020, 20:19:40 UTC | Push lets near their uses (whenever possible) while CSEing += (#5387) * Push lets near their uses (whenever possible) while CSEing += The CSE pass tries to do CSE jointly on the index and value of store nodes. This is to stop: f[x] = f[x] + y from turning into f[x] = f[z] + y This is because the two 'x' indices are not CSE'd together. However, one problem with jointly CSEing the store index and vaues is that after CSEing, the pass puts the lets (the values that were CSE'd) before the new store. That is we get, let(t0...) let(t1...) f[t0] = f[t0] + function_of(t1) Suppose however, there was nothing to CSE between the store index and value, that is the index was unchanged after CSE. In that case, moving lets before the store puts the lets too far away from their uses. This is ok except, there are passes like LoopCarry that are beneficial when they are able to see a long continuous block of stores (eg. when unrolling). But now, they'll see a long sequence of LetStmts. Instead, if the index was unchanged after CSE, we should build up the stores as f[x] = let(t0.. in (value)); This way LoopCarry is given a chance to see a series of stores. Handling this in CSE, means the LoopCarry pass need not be complicated. Change-Id: Iae19e1f69a6b38f3224a64b0c4781533e3862970 * In CSE, when we bundle together the store index and store value, create LetStmts only for CSE'd values that are needed by the store index. The rest can be Let expressions around the store value. * Formatting fix for printing the IR after CSE * Be smarter about pushing lets near their uses when CSEing += In a previous patch, in the code that handles CSEing += store operations, we weren't general enough; we only handled the specific case when the store index remained unchanged when CSE'd together with the store value. This patch is more general. Even if the store index changes, only the use-def chains created from the values used by the new store index that end in defs created by CSE are retained as Let stmts around the new store. Others go as Let expressions around the store value. * Fix some formatting issues exposed by clang-format and remove the inclusion of ExprUsesVar.h in CSE.cpp because it is not used anymore. * Use override in GetVarsUsed in CSE.cpp | 28 October 2020, 20:19:40 UTC |
