LLVM 6: Error in lib/Wrapper/OptSchedMachineWrapper.cpp: error: ‘const struct llvm::MCProcResourceDesc’ has no member named ‘Name’

[Quincunx271]

The error is on line 236:

OptSched/lib/Wrapper/OptSchedMachineWrapper.cpp

Lines 233 to 239 in 7183a5e

	for (unsigned FUIdx = 1; FUIdx < FUTypesCount; FUIdx++) {
	const MCProcResourceDesc *FUResource =
	LLVMSchedModel->getProcResource(FUIdx);
	ResourceIdToIssueType[FUIdx] = FUResource->Name;
	IssueTypeInfo ITI{FUResource->Name, static_cast<int>(FUResource->NumUnits)};
	MM->addIssueType(ITI);
	}

The workaround is to comment out this loop.

This came from @paul-mchugh 's #137 PR. Do you know what would be needed to fix this?

Obviated by the migration to newer LLVM versions (#156)
