similar to: [LLVMdev] making emitInlineAsm protected

It may be moot because Reed is currently rewriting the patch to avoid using EmitInlineAsm and EmitRawText but I wanted to question something here. I'm thinking that hasRawTextSupport() shouldn't be the condition used inside EmitInlineAsm. I think it would be more correct to have a useRawTextSupport() predicate that can return hasRawTextSupport() for (sub)targets that haven't

Ok then. I'll put together a patch early next week to add a hasMatureMCSupport() and use it in EmitInlineAsm(). I don't know which targets should return true for hasMatureMCSupport() at the moment though. I guess X86 and ARM would but are there any others? ________________________________________ From: Rafael Espíndola [rafael.espindola at gmail.com] Sent: 31 January 2014 18:53 To: Daniel

Hello. I come back to this thread. But I want to ask a slightly different question. Is there a way to have LLVM IR language intrinsics that are given at construction time a string that is written at assembly generation time as it is? (so, basically having placeholders of strings in LLVM that remain untouched until the end, including code generation time.) More exactly, I would

Hello, I am working on backend development and would like to utilize my target's MCAsmParser inside of an MCInst-level class implementation. I noticed that the AsmParser is registered with the target registry however I am having no luck grepping for a "template" of how to instantiate it and have yet to find specific documentation on how it is done. Any ideas or help is greatly

I am having a problem with Polycom auto-answer. I have the auto-answer working between PhoneA and PhoneB, but when I try to use the intercom between more then one phone I start having problems. PhoneA dials *3 which calls PhoneB, PhoneC, and PhoneD. All the phones ring, but only one will pick up, the rest will hang up and I get this error on Asterisk: Got SIP response 500 "Internal Server

Hi, I recently switched to LLVM-GCC 4.2 on OS X, to go around a bug caused by gcc with optimized code. Unfortunately, I ran into another weird problem on LLVM-GCC. In my code, there's a file with a bunch of inline assembly blocks, that worked fine with GCC 4.2. Now, when compiling with LLVM-GCC 4.2, weird things happen. Here's an example: (the blocks are larger than that, but a single

You may find it helpful to reference http://www.ibiblio.org/gferg/ldp/GCC-Inline-Assembly-HOWTO.html. In particular, the information regarding clobbers and constraints. Generally speaking, it's best not to use inline assembly at all. What are you trying to do that you find it necessary?

Hi, I' am trying to insert an InlineAsm Instruction in my pass, which FunctionType do I need for Inlineasm? If I understand it right, I need a call instruction to insert the new produced InlineAsm? Thanks for help, Michael for (BasicBlock::iterator bi = i->begin(), be = i->end(); bi != be; ++bi){ std::vector<const Type*> asm_arguments;

Hi Everyone, I am trying to decide on a MC'ized reorg of ARMAsmPrinter for MC/ELF, and had some questions. Currently, it defines quite a few methods like printAddrMode4Operand (linked to ARMInstrInfo.td) that currently assume raw text support in the OutStreamer. Are these methods still supposed to be invoked in the MC'ized path for assembly output? Is JimG's new MC/.s

Hi all, I'm trying to figure out which parameters of a given InlineAsm instruction are its inputs, and which are the outputs (rationale: make sure MSan doesn't check the output parameters of an asm() statement). As far as I understand, this information is only available through the ConstraintInfoVector for the InlineAsm. However there's no exact match between the constraints and the

Hello Mentors, I am currently finding bug in Local Function related optimization due to which runtime failures are observed in some test cases, as those test cases are containing very large function with recursion and object oriented code so I am not able to find a pattern which is causing failure. So I tried following simple case to understand expected behavior from this optimization. Consider

Hi, I am seeing a case, in a private port, of an inline asm with indirect memory references being allocated invalid registers (i.e. registers that cannot be used on loads). For example, the inline asm constraint is correct: call void asm sideeffect "MOV $$r0, $0\0AMOV $$r0, $1\0A", "*m,*m,~{r0}"(i16* @a, i16* %b) #1, !srcloc !1 but then $0 and $1 are allocated to registers
