| 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 |

| 9743fca | Zalman Stern | 01 February 2021, 19:50:40 UTC | Make GPU kernel compilation caching consistent across GPU backends. (#5546) Make GPU context handling more consistent and use a common compilation cache for kernels. Introduces a finalization routine for kernel compilation to indicate when kernels are not strictly required to be defined. Thus allowing them to be unloaded or discarded, but not when they are needed.

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 |
