I need to create a subclass that derives from MCELFStreamer. We use MCELFStreamer for direct object generation and need to override a virtual method in the base class MCStreamer::EmitGPRel32Value(). I have been having trouble creating the subclass due to #include issues. I can't seem to get it right at the lib/target/<my target>/MCTargetDesc level. My first thought is always that I am doing something wrong and that may still be the issue, but it is suspicious that no one has subc...

For your specific problem, I suspect what needs to happen is something like: 1) In MCELFStreamer(), implement EmitGPRel32Value() to add an appropriate fixup, and 2) in ELFObjectWriter.cpp, teach the Mips bits what relocation type to use for that fixup, if it doesn't know already.

...should add the following to MC/MCFixup.h: FK_GPRel_1, ///< A one-byte pc relative fixup. FK_GPRel_2, ///< A two-byte pc relative fixup. FK_GPRel_4, ///< A four-byte pc relative fixup. FK_GPRel_8, ///< A eight-byte pc relative fixup. In MC/MCStreamer.cpp MCStreamer::EmitGpRel32Value() Figure out how to mark it with the imprint of FK_GPRel_4 In MC/ELFObjectWriter.cpp MipsELFObjectWriter::GetRelocType() Add a switch case for FK_GPRel_4 to put out the correct target specific relocation. Is that correct? Did I miss anything? Thanks, Jack

I have managed to produce correct relocation records for my jump table with the below code, but am baffled to how to emit the text addresses to the data section. I'm sure it is just a few lines of code. Any suggestions? Jack void MCObjectStreamer::EmitGPRel32Value(const MCExpr *Value) { MCDataFragment *DF = getOrCreateDataFragment(); int Size = 4; // Assumption is that this is alway for 4 byte value DF->addFixup(MCFixup::Create(DF->getContents().size(), Value, FK_GPRel_4)); DF->...
