> Why isn't the ABI reflected in the triple? Unfortunately, there's no easy answer to that. Some targets are better than others but generally speaking triples are very ambiguous. For example, in (most) GCC mips-linux-gnu/mips64-linux-gnu toolchains both triples produce 32-bit big-endian binaries for MIPS-I by default. Vendors can override the majority of this so it's entirely

There's a lot of legacy and inertia to overcome if we try that. The intention is to map the ambiguous/insufficient GNU triples onto an internal representation as early as possible and pass that internal

Hi all I have a question about the '-fno-exceptions' option with clang and 'ExceptionsType' on MCAsmInfo. I am looking for a way to avoid generating stack unwinding codes when compiling with the "armv7-none-linux-gnu" triple using clang. I tried the '-fno-exceptions' option in order to do that, but unwinding function symbols like

Hi all. I fully understand that the problem is a bit OT for llvmdev, but I'm stuck for two days now and I really need some direct push. To the problem. I have a C++ shared library, that's working with llvm C++ api. Consider a function: static Object llvm_Target_createMCAsmInfo(Object self, Object tripleName) { llvm::Target target = from_ruby<llvm::Target>(self); char const

Hi Rafael, Sure, the expansion of at least .cpload should be done in the Target ELFStreamer but AFAICS it doesn't solve my initial problem. MCCodeGenInfo is not created in tools where CodeGen isn't needed (llvm-mc) and it's still not possible to access the Relocation Model in MCObjectFileInfo from the target streamer (private member). Am I missing something obvious ? There are many

I've actually tried to compile both LLVM and my lib with -frtti with same results.

Some Mips macros (e.g. la[1]) and the handling of Mips directives used for Position-Independent Programming (e.g. .cpload[2]) require access to Reloc::Model from within the Assembly Parser but there doesn't seem to be a way to do it in its current form. 1) Reloc::Model is passed to MCObjectFileInfo but it's a private member of that class 2) TargetMachine is not accessible I can also

I don't know what the ./configure equivalent is, sorry. LLVM_REQUIRES_RTTI is an internal variable. It works as you say, but there is no guarantee about it. Adding a

llvm-dev, Thanks so much in advance for any help, tips, or advice you may be able to offer me. I'm going to try to avoid the big-picture description of the project I'm working on, and only talk about the parts that I have trouble with / currently need to implement. -- I've been starting by taking the source code from the "llvm-mc" tool, and working that down into a

Good. Copying llvmdev for the record.

Dear llvm, Recently (approximately a week ago) Clang and LLVM started to failed at building. Assuming it was my incompetence, I cleared everything and started witha fresh checkout (not that I changed it though). I am on Ubuntu 10.04 LTS 64-Bit. And I configure and compile with CMake. The error message I get at approximatley 66% is as follows: Linking CXX executable ../../bin/llvm-mc

currently, there is no (easy) way to set the AssemblerDialect. the only method i am aware of is to set that via cl:opt. this patch fixes that by adding a public function setAssemblerDialect() to class MCAsmInfo.

What's the use case?
