This is just more helpful for knowing what all needs to be fixed when CI fails.
Replacing `iter_specializations` (which repeatedly invokes a callback) with an iterator implementation allows `Itertools::format_with` to be used more broadly, which in turn allows disparate string interpolation to be combined and hopefully provide greater context to the reader.
Updates `get_load_function` to return `svld{n}_{ty}` when loading a
scalable vector type. Caller of `get_load_function` will still need
updated to handle passing the predicate arguments to these load
functions.
Updates the headers used by generated C code and the target feature flags passed to the C compiler to enable SVE.
Some SVE intrinsics take booleans as arguments, so there is a need to support generating a test value array for booleans.
Constraints that correspond to enum types - such as `svpattern` and `svprfop` - need to be converted to the enum type in order to be used in a generic instantiation - so introduce a const function for both types that provides this mapping.
Predicate arguments of type `svbool_t` do not need test value arrays to be generated as the same enable-all-lanes predicate will be passed to all invocations of the intrinsic under test. There is no `svld1` equivalent for `svbool_t` that could be used even if there were test values to use.
Support defining a local variable containing the predicate that will be used with all subsequent scalable vector intrinsics.
Implementation of `get_comparison_function` and `get_predicate_function` for SVE which uses the relevant SVE intrinsics.
Instead of assuming that any scalable boolean argument is a predicate, handle predicates specifically and generate test values for `svbool_t` values.
SVE isn't a baseline target feature for `aarch64-unknown-linux-gnu` but should be enabled when running tests.
Like with non-SVE test generation, comparison of float results in scalable vectors need special-handling of comparisons.
Enables generation of tests for SVE intrinsics leveraging the changes from the previous commits.
This makes it far easier to debug what's potentially gone wrong with an intrinsic test.
Same as previous redefinitions in stdarch#2163 - these were missed in that PR because the hardware being tested on was missing the hardware feature required for the instructions these use.
