...gister 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 and PowerPC) looks like this: void MipsInstPr...

OK, here's a new patch that adds the infrastructure and the implementation for X86, ARM and PPC of GetInstSize and GetFunctionSize. Both functions are virtual functions defined in TargetInstrInfo.h. For X86, I moved some commodity functions from X86CodeEmitter to X86InstrInfo. What do you think? Nicolas Evan Cheng wrote: > > I think both of these belong to TargetInstrInfo. And

Thx again Evan for the review. Here's a new patch for the JIT in itself. The major changes are: 1) A JITMemoryManager now has a flag saying "I require to know the size of what you want to emit" 2) DwarfJITEmitter is augmented with GetSize* functions 3) JITEmitter::startFunction checks if the JITMemoryManager requires to know the size. If so, it computes it and gives it through the

Dear all, Here's a new patch with Evan's comments (thx Evan!) and some cleanups. Now the (duplicated) exception handling code is in a new file: lib/ExecutionEngine/JIT/JITDwarfEmitter. This patch should work on linux/x86 and linux/ppc (tested). Nicolas -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: jit-exceptions.patch URL:

Hi everyone, Here's a patch that enables exception handling when jitting. I've copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need to factorize it, but the functionality is there and I'm very happy with it :) lli should now be able to execute the output from llvm-gcc when using exceptions (the UnwindInst instruction is not involved in this patch). Just add the
