e5ed226 Fix Python error handling (#7352) * Fix Python error handling Error handling in the Python bindings wasn't quite right for JIT: We previously replaced halide_error() to throw a C++ exception. Sounds good, but unfortunately, doesn't work reliably: if called from jitted code (which doesn't know about C++ exceptions), the throw statement may be unable to find the enclosing try block (which is outside jitted code), meaning it will call std::terminate. Now, instead, we just leave the JIT error handler unset, and call with an explicit JITUserContext with a custom print handler; in theory, this meant that the code in JITFuncCallContext::finalize() would check for an error after the call into jitted code, and call `halide_runtime_error` if so (which would then trigger an all-in-C++-exception). Unfortunately... (2) JITFuncCallContext is broken by design; it mutates the input JITUserContext, so that trying to use the same JITUserContext for two calls in a row leaves you with a JITUserContext with (at least) the error_handler set. Since at least one of the realize() calls does this twice (once for bounds query, once for execution), this means that an error in the second call would never be seen, since finalize() only reported errors if there wasn't a custom error handler on input. Per @abadams suggestion, we work around this by treating 'JITErrorBuffer::handler' as 'no custom error handler', which is mostly true. (But really, JITFuncCallContext and JITUserContext are a hard-to-reason-about mess and arguably need to rethought entirely.) (3) Removed entirely-unnecessary overrides of runtime print and error handlers from PyStubImpl; despite the comments, this code is unnecessary. * format 15 February 2023, 17:03:41 UTC

7963cd4 Change early-bound default args in Python bindings to late-bound (#7347) In PyBind11, if you specify a default argument for a method, it is evaluated when the Python module is initialized, *not* when the method is called (as you might expect in C++). For defaults that are just constants/literals, this is no big deal, but when calling get_*_target_from_environment, this means it is called at module init time -- also normally not a big deal (since the values ~never change at runtime anyway), with one big exception (no pun intended): if the function throws an exception (e.g. via calling user_assert() or similar), that exception is thrown at Module-initialization time, which is a much more inscrutable crash, and one that is very hard to recover from. This may seem unlikely, but can happen pretty easily if you set (say) HL_JIT_TARGET=host-cuda (or other gpu) and the given GPU runtime isn't present on the given system; the current behavior is basically "make if impossible for the libHalidePython bindings to run", whereas what we want is "runtime exception thrown when you call the method". This changes the relevant methods to use `Target()` as the default value, and inside the method wrapper, if the value passed equals `Target()`, it replaces the value with the righ `get_*_target_from_environment()` call. (This turned up while doing some testing of https://github.com/halide/Halide/pull/6924 on a system without Vulkan available) 14 February 2023, 17:14:05 UTC
8bd07fb Fix tuple output bounds checks (#7345) Fix #7343 Tuple outputs weren't getting appropriate bounds checks due to overzealous culling of uninteresting code in the add_image_checks pass. 14 February 2023, 01:52:53 UTC

22aed20 Devirtualize the protected compile() methods in Codegen_C (#7341) With the addition of `preprocess_function_body()`, neither of these need to be virtual, and devirtualizing them avoid `hidden overloaded virtual function` warnings in subclasses that don't override them 11 February 2023, 02:42:05 UTC
6c5ca8e Tiny improvements in codegen in C backend (#7337) * Tiny improvements in codegen in C backend (1) Emit `true` or `false` instead of `(bool)(0ull)` etc for bool literals (2) Avoid redundant temporaries in print_cast_expr(), which occur in a small but nonzero number of cases Basically this means that code currently like ``` bool _523 = (bool)(0ull); bool _524 = (bool)(_523); ... foo(_524); ``` becomes ``` foo(false); ``` ...I'm sure this has no output on final object code, but it makes the generated C code less weird to read. * Also avoid extra intermediates for typed nullptr * Also use std::isnan() and std::isinf() * Update CodeGen_C.cpp 11 February 2023, 00:34:41 UTC

a6c5be7 Add a hook to Codegen_C::compile() (#7335) At least one subclass of Codegen_C currently has to replicate ~all of the compile(LoweredFunc) method, with the result that it has often gone stale (and still is stale) wrt changes in the base; this adds an optional method to allow some modifications to the function body just before it is printed, to avoid redundant code. 10 February 2023, 21:28:51 UTC

35322c3 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
