...r back to its corresponding dwarf register number in function InstPrinter->printRegName? I just want to have it output the same register number as before (the same output the false path would produce). void MCAsmStreamer::EmitRegisterName(int64_t Register) { if (InstPrinter) { const TargetAsmInfo &asmInfo = getContext().getTargetAsmInfo(); unsigned LLVMRegister = asmInfo.getLLVMRegNum(Register, true); InstPrinter->printRegName(OS, LLVMRegister); } else { OS << Register; } } My current implementation of printRegName which I copied from other backends (X86, ARM a...

Hi, As a first step to port the LLVM chain on an in-house big-endian processor, I'm integrating the native assembler as a new '-assemble -arch=' in llvm-mc. All work quite well, I have a correct output ELF format except that generated code is little-endian. I've understood that the endianess of the LLVM chain is controlled by the DataLayout class, but it appear to me that llvm-mc

...s that yasm doesn't understand. I've made a X86YasmInstPrinter, and added it to the x86.td, as a new variant, and due to it having a new Variant number, I'm having to edit all the X86*.td files and add the extra variant's descriptions in the { | } blocks. I've also added a new ASMInfo class with the required changes for yasm. Now what is worrying me is the number of .td files I'm having to touch, and most of the changes are adding a variant with exactly the same code as the intel variant, there are just a few cases that a slightly different. I'm about 1/4 way through...

...though--probably because the Darwin assembler supports quoted symbols (i.e. you can enclose an identifier in quotes).

The issue is of course that MCAsmInfo mixes both assembler and object file format capabilities. Allowing quoted names has nothing to do with COFF ;/. So it se...

I'd like to set all Global Symbols to be prefixed with '_' ; however, when I set GlobalPrefix in TargetMCAsmInfo.cpp, this also applies to library calls (adds extra underscore which makes 3 so linkage failure), which I don't want.

In the case I posted I had removed that line, however, you still get the __3F_ in the generated assembly with it.
