Added extra information in LLT to support ambiguous fp types during GlobalISel. Original idea by @tgymnich Main differences from https://github.com/llvm/llvm-project/pull/122503 are: * Do not deprecate LLT::scalar * Allow targets to enable/disable IR translation with extenden LLT via `TargetOption::EnableGlobalISelExtendedLLT` (disabled by default) * `IRTranslator` use `TargetLoweringInfo` for appropriate `LLT` generation. * For this reason added flag in GlobalISelMatchTable` to allow switch between legacy and new extended LLT names * Revert using stubs like `LLT::float32` for float types as they are real now. Added `TODO` for such cases. Also MIRParser now may parse new type indentifiers. --------- Co-authored-by: Tim Gymnich <tim@gymni.ch> Co-authored-by: Ryan Cowan <ryan.cowan@arm.com>
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
