- MIParser: If the successor list is not specified successors will be added based on basic block operands in the block and possible fallthrough. - MIRPrinter: Adds a new `simplify-mir` option, with that option set: Skip printing of block successor lists in cases where the parser is guaranteed to reconstruct it. This means we still print the list if some successor cannot be determined (happens for example for jump tables), if the successor order changes or branch probabilities being unequal. Differential Revision: https://reviews.llvm.org/D31262 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@302289 91177308-0d34-0410-b5e6-96231b3b80d8
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'.
