similar to: Problem Compiling AsmParser

Hi, I try to create a backend to support AsmParser, but it hasn't the red part as below. I find the Mips has this. Do you know how to make it appear? Jonathan #ifdef GET_ASSEMBLER_HEADER #undef GET_ASSEMBLER_HEADER // This should be included into the middle of the declaration of // your subclasses implementation of MCTargetAsmParser. unsigned ComputeAvailableFeatures(uint64_t

Thank you :) If you mean this field, it looks everything is ok: field bits<16> Inst = { 0, 1, 1, 0, 1, 0, 0, 0, 0, 0, Dr{2}, Dr{1}, Dr{0}, At{0}, 0, 0 }; Is possible that the problem might be on the TestAsmParser.cpp side?

Hi, I'm looking into development of an llvm-objdump utility for hexagon and I've read that there is a way to have tablegen automatically generate decode tables for you. I've not been able to find much info on this topic, the best info I've been able to find is this tutorial: http://www.embecosm.com/appnotes/ean10/ean10-howto-llvmas-1.0.html#idp3570032 I've managed to get

Hi Everyone, I have been implementing the integrated assembler for the OpenRISC 1000 architecture. Whilst doing this I noticed a lack of documentation around this area. To help others, I have written a how to guide which uses the OpenRISC 1000 as an example. This can be downloaded from http://www.embecosm.com/download/ean10.html. I hope this document proves useful. Any feedback would be

Hello, I'm archiving a number of bitcode files via gold plugin based on LLVM 3.4. When I find a thumbv7 bitcode with a couple of module asms, I get a segfault in ARMAsmParser::parseDirectiveFnStart because getTargetStreamer returns NULL. Frankly, I don't see how this is supposed to work because as far as I understood LTOModule::addAsmGlobalSymbols only creates a RecordStreamer

Hi everyone. We're interested in contributing a Hexagon assembler to MC and we're looking for comments on a good way to integrate the grammar in to the infrastructure. We rely on having a robust assembler because we have a large base of developers that write in assembly due to low power requirements for mobile devices. We put in some C-like concepts to make the syntax easier and this

The returned number is the register id as defined in <YourTarget>GenRegisterInfo.inc. These numbers

Dear all, in my TestRegisterInfo.td file, I defined a register like this: class TestReg<bits<6> enc, string name> : Register<name> { let HWEncoding{5-0} = enc; let Namespace = "TEST"; } def D0 : TestReg<0x01, "d0">, DwarfRegNum<[1]>; but when I compile, the result I have in TestGenAsmMatcher.inc is this: case 'd': // 7

Thanks you. I'm new to LLVM backend, so the help is much appreciated.

When I registered for dev conference, there was a field asking what I was particularly interested in learning. I didn't fill it out then , but it occurs to me now that I'd really enjoy a tutorial on how to develop a new back end. I spent some time recently reviewing existing material (documentation and code) and not making a lot of progress. Indeed, under some time pressure, I'm

Resending, any pointers are much appreciated.

Short version: If the integrated assembler accepted assembly strings as input, more targets could take advantage of integrated assembly. The longer version: For a given assembly statement, my out-of-tree target has complex instruction selection logic -- more so than the in-tree targets. This target uses variable length instructions and a laborious hierarchy of tblgen AsmOperands to do the job.

(Sorry about the wall of text, it ended up as a brain dump of a bunch of backend-related documentation that I know about/have bookmarked in the past. Hopefully there's something useful in there.)

Hi All, I wrote a very crude and simple AsmParser for my backend. llvm-tablegen also generates asm-matcher .inc file without any error. I have included the .inc file in my class for AsmParser. However, while building llvm, in linking stage for LTO, i am getting error - undefined reference to functions - ComputeAvailableFeatures, MatchInstructionImpl, MatchRegisterName and
