[LLVMdev] addPassesToEmit(Whole)File changes?

[Marcel Weiher]

Hi folks,

just installed the new llvm 1.9 build and noticed that my code no  
longer worked.  It seems something has changed with  
addPassesToEmitFile().  First, the arguments to that method changed so  
that it no longer takes a PassManager, but only a  
FunctionPassManager.  Instead there is a addPassesToEmitWholeFile()  
method, but that is marked as optional, and when I change my code to  
use that there is no output (only an empty file).

I tried changing to code to use a FunctionPassManager, but that then  
requires the run() call to be changed to individual functions, and I  
am not convinced I want to do that because what I am outputting are  
not just functions, but also some global data.

I am currently installing older versions to see if that will work, but  
of course I will need to get it to work with the newest llvm version  
at some point.

Any pointers?

Thanks!

Marcel



This is my current code:

-(void)dumpAssemblerToFile:(NSString*)filename
{
	TargetMachine::CodeGenFileType FileType = TargetMachine::AssemblyFile;
	std::string err1;
	Module *M=(Module*)module;
	const TargetMachineRegistry::Entry* entry=  
TargetMachineRegistry::getClosestStaticTargetForModule( *M,  err1 );
	TargetMachine &target=*entry->CtorFn( *M, "" );
	[self generateMethodLists];
	std::ostream *outStream = 0;
	PassManager passes;
	outStream = new std::ofstream( [filename fileSystemRepresentation] );
	TargetData *data =new TargetData( *target.getTargetData());
	passes.add(data);
	target.addPassesToEmitFile(passes, *outStream, FileType, false);
	passes.run(*M);
	delete outStream;
}
