| 35322c3 | Steven Johnson | 10 February 2023, 00:22:10 UTC | Fix a subtle uninitialized-memory-read in Buffer::for_each_value() (#7330) * Fix a subtle uninitialized-memory-read in Buffer::for_each_value() When we flattened dimensions in for_each_value_prep(), we would copy from one past the end, meaning the last element contained uninitialized garbage. (This wasn't noticed as an out-of-bounds read because we overallocated in structure in for_each_value_impl()). This garbage stride was later used to advance ptrs in for_each_value_helper()... but only on the final iteration, so even if the ptr was wrong, it didn't matter, as the ptr was never used again. Under certain MSAN configurations, though, the read would be (correctly) flagged as uninitialized. This fixes the MSAN bug, and also (slightly) improves the efficiency by returning the post-flattened number of dimensions, potentially reducing the number of iterations f for_each_value_helper() needed. * Oopsie * Update HalideBuffer.h * Update HalideBuffer.h | 10 February 2023, 00:22:10 UTC |

| 6ecdcbd | Steven Johnson | 11 December 2022, 18:05:55 UTC | Tighten alignment promises for halide_malloc() (#7222) This makes a couple of changes to the behavior/implementation of `halide_malloc()`: * Currently, halide_malloc must return a pointer aligned to the maximum meaningful alignment for the platform for the purpose of vector loads and stores. This PR also adds the requirement that the memory returned must be legal to access in an integral multple of alignment >= the requested size (in other words: you should be able to do vector load/stores "off the end" without causing any faults). * Currently, the `halide_malloc_alignment()` function is used to determine the default alignment; this cannot be overridden by user code (well, it can be, but the override will have no useful effect). It is intended to be "internal only" but is used in at least one place outside the runtime (apps/hannk). This change removes the call entirely, in favor of a call that is harder to access from outside the runtime and much less likely for end users to attempt to call. (It also changes apps/hannk to stop using it.) | 11 December 2022, 18:05:55 UTC |

| 16421a7 | Steven Johnson | 09 December 2022, 17:21:30 UTC | Revise simd_op_check tests to ignore HL_TARGET (#7207) (#7216) * Revise simd_op_check tests to ignore HL_TARGET (#7207) The simd_op_check tests have historically only run using the value of HL_TARGET, which mean that the coverage they had was low (since HL_TARGET is only set to values that are runnable on at least one buildbot). This change completely disconnects these tests from HL_TARGET; instead, each test now tests for a range of targets appropriate to the architecture being tested. On all platforms, they still compile to assembly and verify that the correct instructions are generated; additionally, if the host platform can JIT for the given target, it verifies that the results are as expected. * Update simd_op_check_riscv.cpp * Update simd_op_check_x86.cpp * Update simd_op_check_x86.cpp * Update simd_op_check_arm.cpp * Add more features that must match; re-enable the bfloat instructions * Update simd_op_check_x86.cpp * Update simd_op_check_riscv.cpp * trigger buildbots * Fix simd_op_check_wasm | 09 December 2022, 17:21:30 UTC |
