...the need to handle assembly and object emission. I have moved directives for PPC, Mips and ARM over to the new interface. If you think I forgot some, need to add more or maintain an out of tree target, this is what you need to do for a Foo target: Implement 3 classes: * FooTargetStreamer : public MCTargetStreamer * FooTargetAsmSreamer : public FooTargetStreamer * FooTargetELFStreamer : public FooTargetStreamer FooTargetStreamer should have a pure virtual method for each directive. For example, for a ".bar symbol_name" directive, it should have virtual emitBar(const MCSymbol &Symbol) = 0; The...

Hi, I've run Clang Static Analyzer checker alpha.cplusplus.NewDeleteLeaks over LLVM codebase to detect false-positives and at the same time eliminate memory leaks. The majority of leaks were detected in lib/Target/* and lib/MC/*. In all cases the similar trick was detected as a leak (example from lib/Target/Sparc/MCTargetDesc/SparcMCTargetDesc.cpp) : static MCStreamer

...ption to TargetOptions struct that provides access to abi string. This info is stored in MCSubtarget class(ARMSubratget in this case) and distributed to other libraries. Unfortunately, for Mips we need this info in other classes that don't have access to MCSubtarget class, like MCAsmBackend and MCTargetStreamer and instantiating a new copy od TargetOption causes link errors as it is already instantiated in some drivers(llc.cpp for example). What would be the proper way to get the TargetOptions struct available in other classes? Kind regards, Vladimir -------------- next part -------------- An HTML atta...

Hi Craig and Rail, At Movidius, we have had to make a few changes to ‘MCAsmStreamer’ to support our assembler which is not ‘gas’ compliant. Earlier versions of LLVM (3.1 and 3.2) did have a separate header for ‘MCAsmStreamer’, and we had previously sub-classed this. The following are modifications that we have had to make because although ‘MCAsmStreamer’ does most of what we need,

Does anybody know if there is a particular reason why MCAsmStreamer doesn't have its own .h file? https://github.com/llvm-mirror/llvm/blob/0e66a5f53c74056f95d178c86531d7d9cfb23da9/lib/MC/MCAsmStreamer.cpp#L41 It seems like it is a good idea to have this class declared as its own module ( its own .cpp and .h files). That would make it easier to inherit from it if there is a need (like in my
