machine-region-info.mir: Slightly simplify test, -mtriple llvm-svn: 295520
2017-02-18 08:48:43 +08:00
# RUN: llc -mtriple=x86_64-- -run-pass=machine-region-info %s -debug-only=machine-region-info -o /dev/null 2>&1 | FileCheck %s
# REQUIRES: asserts
MachineRegionInfo: Fix pass initialization - Adapt MachineBasicBlock::getName() to have the same behavior as the IR BasicBlock (Value::getName()). - Add it to lib/CodeGen/CodeGen.cpp::initializeCodeGen so that it is linked in the CodeGen library. - MachineRegionInfoPass's name conflicts with RegionInfoPass's name ("region"). - MachineRegionInfo should depend on MachineDominatorTree, MachinePostDominatorTree and MachineDominanceFrontier instead of their respective IR versions. - Since there were no tests for this, add a X86 MIR test.

MIParser/MIRPrinter: Compute block successors if not explicitely specified - 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.
