d523b83 | Steven Johnson | 13 March 2021, 00:54:23 UTC | Fix deprecation warnings for trunk LLVM (#5803) (1) Both the 'deprecated' and new, non-deprecated variants existed back to at least LLVM10, and the deprecated variant was commented as deprecated at that point as well; the change in LLVM13 is that they are now annotated with LLVM_ATTRIBUTE_DEPRECATED so we get compiler warnings (and thus errors). (2) The fixes are simply replicating what the old, deprecated methods did internally. | 13 March 2021, 00:54:23 UTC |

This reverts commit 03efb3f784b3078b64961c98edde383f4de04fb4. * Don't combine ifs, split them instead. * Update trace * clang-tidy/clang-format * Remove splitting of ifs, it breaks brittle tests. * Safer check on old conditions. * Fix producer guard condition. * Interval fixes. * Handle sliding backwards * Handle transitive dependencies. * Backport abadams' fix from abadams/slide_over_split_loop * Fix select visitor. * More simplifier rules. * Bring back old logic as a fallback. * Avoid specializations corrupting sliding * Fix boneheaded rule errors. * Fix slightly conservative bounds at the max for split case. * This pattern is too sensitive to the simplifier.

c2a0db1 | Steven Johnson | 10 March 2021, 23:39:27 UTC | Fix correctness_memoize on arm32 (#5799) Conversion from a pointer to an integer is "implementation defined"; in general, conversion to `uintptr_t` is reliable, but other conversions aren't. It turns out that for our arm32 compiler, casting a pointer to a `uint64_t` sign-extends, rather than zero-extends, causing unexpected behavior in memoize cache eviction *if* the pointer is in the top half of memory. The fix here is simple (cast to `uintptr_t` directly), but it brings up the question of where else in our codebase we might be doing direct conversions elsewhere in our code without noticing the potential UB. | 10 March 2021, 23:39:27 UTC |
7a8c771 | Steven Johnson | 10 March 2021, 22:53:40 UTC | Fix wasm-interp ucon error (#5797) This is a subtle error that only shows up in builds with assertions enabled in wabt; the issue is that we ask for an int64 value from a wabt `Value` struct, but that struct only has an int32, so an assertion can fail. (Note that there is always storage for both, and the values are constrained and unused inside the JIT anyway, so this is mostly just a cosmetic fix.) Also added a .gitignore entry. | 10 March 2021, 22:53:40 UTC |
34c402f | Dillon Sharlet | 10 March 2021, 21:54:51 UTC | Fix bug found by asan from #5784 (#5798) | 10 March 2021, 21:54:51 UTC |
c67f486 | John Lawson | 10 March 2021, 18:51:33 UTC | Move where intrinsic function attributes are set (#5795) * Make declare_intrin_overload return LLVM function * Make names same as elsewhere * Remove unneeded enum name * Set moved attributes in Hexagon backend * Use declare_intrin_overload for ARM vabdl * Fix ARM vabdl intrinsic types * Format and clang-tidy * Rename intrinsic to widening_absd | 10 March 2021, 18:51:33 UTC |
78ff307 | Lars | 10 March 2021, 18:35:50 UTC | Display the GPU device code as a string in the C/C++ backend (#5757) * Added support for a OpenCL backend through the C backend No correctly handles assert of kernel call Fixed clang-formatter Clang-tidy fixes * Remove references to alternative OpenclHost code * Only initialize GPU context once (removes name conflicts) squash commit * (Pretty) Print the kernels in the C backend clang formatting remove virtual * Fixes after review fixes after review 2.0 fixes | 10 March 2021, 18:35:50 UTC |
e75d9fb | Dillon Sharlet | 09 March 2021, 22:16:21 UTC | Fix out of bounds reads in strided ARM loads (#5784) * Safer version of vldN code generation. * Only be more conservative with alignment for external buffers. * Add tolerance to allocation size tests. * Remove old comments. * Improve ARM alignment and vldN code generation. * Remove merge straggler * Fix alignment condition (again). * Fix alignment. * Avoid divide by zero. * Move CodeGen_ARM's logic for strided loads to CodeGen_LLVM. * Fix comment. * clang-format. * Remove sketchy alignment check. | 09 March 2021, 22:16:21 UTC |
a83ab23 | Dillon Sharlet | 08 March 2021, 19:24:07 UTC | Simplifier rules for nested broadcasts (#5794) * Handle some reassociation when simplifying nested broadcasts. * clang-format. | 08 March 2021, 19:24:07 UTC |
89f5ee7 | Andrew Adams | 05 March 2021, 20:00:57 UTC | Add missing min/max/+/- rules (#5788) These are almost all of the rules in <= four in terms of min/max/add/sub ops leaves that simplify to something with <= three leaves. I left out things of the form: max(max(x, -x), 0) -> max(x - x) While correct, that transformation actually hurts our ability to analyze that expression. | 05 March 2021, 20:00:57 UTC |

06b208f | Dillon Sharlet | 04 March 2021, 18:11:57 UTC | Move codegen backends into anonymous namespaces in source files and don't build them if not enabled (#5776) * Remove unused vertex buffer parameters. * Offload GPU code in a lowering pass instead of via CodeGen_GPU_Host. Fixes #5650, fixes #2797, fixes #2084, now #1971 is more relevant. * clang-format. * clang-format sorting is case sensitive!? * clang-tidy * Move codegen backends into anonymous namespaces in source files. * clang-format * Pass type arguments correctly. * Update OffloadGPULoops.cpp * trigger buildbots * trigger buildbots * Hack around tests that rely on the IR for offloaded GPU loops. * Fix missing include. * Remove unused include. * clang-tidy * Use custom lowering pass to see code before GPU offloading * Speculative fix for segfault * Fix const correctness * Fix error on unused variables in generated code.

01f5e73 | Steven Johnson | 02 March 2021, 18:06:11 UTC | Update simd_op_check for the final wasm simd128 spec (#5779) The final revision of the wasm simd128 spec (https://github.com/WebAssembly/simd/blob/master/proposals/simd/SIMD.md) added some ops and tweaked some others. This just augments the wasm section of simd_op_check so that all the ops are referenced, with the new (or still-unimplemented) ops commented out with TODOs. Most of the new ops will likely be implemented via pattern matching in Codegen_WebAssembly, but before that can happen in any efficient way, WABT needs to be updated to recognize all the ops in the final spec (it doesn't currently, and so we can't even load code with those ops without cratering). See https://github.com/WebAssembly/wabt/issues/1617 for tracking bug. (Also: drive-by fix in CodegenLLVM to fix prettyprinting of some debug output) | 02 March 2021, 18:06:11 UTC |

14bab78 | Steven Johnson | 24 February 2021, 19:14:54 UTC | Constrain calling convention for PyStub (#5761) There are two calling conventions that are sensible when calling a Generator from Python: - Inputs are specified via keyword arguments (verbose but more readable) - Inputs are specified via positional arguments (terse but more like C++) However, the current PyStub implementation also allows for mixing positional and keyword forms of input (as long as no input is specified multiple times). This change removes that possibility (requiring either all-keyword or all-positional for inputs). I'm not sure why I thought this was a good option originally, but upon reflection (and examination of existing code), calls written in this way tend to be a confusing mess that require too much care when reading, and I think we'd be better off just forbidding this entirely. Note that this technically is a breaking API change; any user code that used this technique previously would now throw an exception and need a (trivial) update. That said, this is (AFAIK) a very rarely used API, and I rather suspect that existing code that relies on being able to mix positional and keyword inputs in this way is likely to be doing so inadvertently rather than deliberately. | 24 February 2021, 19:14:54 UTC |

a0fde42 | Steven Johnson | 17 February 2021, 22:48:03 UTC | Eradicate reinterpret() from runtime_internal.h (#5748) * Eradicate reinterpret() from runtime_internal.h The reinterpret<>() function in runtime_internal.h is dangerous and should not be allowed to exist: it copies from one type to another, copying the minimum of the two sizes, but with no allowance for ensuring that any "extra" bits in the destination are filled in with, well, anything. I have no evidence of a bug specifically caused by this, but a usage such as `reinterpret<uint64>t>(some_ptr)` on a 32-bit runtime will leave the upper 32 bits of the result undefined. Maybe they'll never get used, but this function is a bug waiting to happen. Fortunately, the only usages of this evil thing are all in hexagon_host.cpp, and all are used to convert between a uint64_t and an ion_device_handle* (which is sometimes represented as a void*). Replacing the handful of usages with bespoke functions to do these conversions seems much safer. | 17 February 2021, 22:48:03 UTC |

This seems like a lot of work some something of marginal use, but I'm reluctant to suggest removing it entirely (it's possible it could break someone's code), and refactoring it in this way will make some subsequent Generator refactoring easier to understand and review. | 09 February 2021, 18:00:58 UTC |

6e3fb56 | Steven Johnson | 26 January 2021, 04:09:53 UTC | FIx intermittent OSX Python crash (#5667) * FIx intermittent OSX Python crash The OSX buildbot has been crashing intermittently on some python tests; debugging showed that in some situations, Introspection's calls to `backtrace()` include bogus addresses (eg 0x08), which cause segfaults when you try to inspect memory near them. The reasons for this aren't entirely clear -- for instance, it only seems to repeat reliably when using the Makefile rather than CMake, and only when doing an 'out-of-tree' build. Rather than try to run this to ground further, this PR just checks for address fields that seem obviously unreasonable (first 256 bytes of address space) and ignore them. * Add -fno-omit-frame-pointer, update sanity check * Update Introspection.cpp | 26 January 2021, 04:09:53 UTC |
