similar to: [LLVMdev] Is there any tool can generate MIPS ELF file?

Hi Matheus, Thank you for your information! Do you known where do download MIPS ABI/EABI document? Thanks in advance! -- Best Regards, Yu Rong Tan On Thu, Jun 12, 2014 at 7:14 PM, Matheus Almeida <Matheus.Almeida at imgtec.com> wrote: > An assembler is the tool you're after.

Thank you very much for your information and documents! Why Imagination Technologies do not offer the latest MIPS ABI document download link just like the ISA docs? If they thought no much people interested in that doc, they had to make greate effort on compiler like GCC,LLVM by themself,then why GCC disagree with some MIPS ABI, it should be freely designed by MIPS ABI designer and compiler

The linker will ensure that the end-user doesn't try to do the second step before the first step is finished since it will refuse to link a binary that contains both O32 and O32+fp64. It will produce an O32 binary given a combination of O32+fpxx, and similarly a O32+fp64 binary given a combination O32+fpxx and O32+fp64.

Hi, -- Best Regards, Yu Rong Tan

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

You will need to install a cross compiler. I think you can find one somewhere in this link: https://sourcery.mentor.com/GNUToolchain/ Once you have a cross compiler, this should do what you want (if you want little-endian code): clang -target mipsel-unknown-linux -ccc-clang-archs mipsel -O3 hello.c -o hello.bc -emit-llvm llc -march=mipsel hello.bc -o hello.s mips-linux-gnu-gcc hello.s -o hello

For a target that hasn't implemented branch relaxation (yet), does anyone know what is the preferred way to report an error if a fixup cannot be applied because, for example, the destination of a branch is out of range? I suppose I could use asserts just like AArch64 is doing but that won't stop the assembler of emitting a branch to an undesired location in release builds. Does anyone see

Maybe try: .set noat AT is needed to create certain instructions from pseudo instructions, so you have to be careful how you use this. Some instructions that you can use in Mips assembler are in fact pseudos. While AT is not available to it (.set noat), the assembler can not assemble certain pseudos for you.

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

There is also: 1) an alternate clang driver at http://code.google.com/p/alternate-clang-driver/ . This makes it more or less gcc compatible. 2) there is a way to invoke it all directly with just a call to clang as is with x86/linux but it's not totally finished. i will try and post something about this. the direct form will work if you are on a mips linux machine but there are still some

Thanks Akira, it worked!

Matheus, The ARM backend reports these kinds of errors using FatalError method of MCContext. You can see some examples in ARMAsmBackend.cpp (search for "out of range pc-relative fixup value"). -David From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Matheus Almeida Sent: Tuesday, December 03, 2013 5:37 AM To: llvmdev at cs.uiuc.edu

I upgraded my versions of llvm, clang and compiler-rt to the top-of-tree versions from last night (r180162, April 24). I recompiled debug versions of llvm, clang and my code. I then regenerated my test case and the results were the same - I can list lines of dwarf1.lsp in lldb but I can't set break-points or do anything else (what else should I be able to do?). The updated file that

Hi, How can I generate executable to mips with llvm-gcc. I'm using Ilvm-2.9, X86PC and the following commands: llvm-gcc -emit-llvm hello.c -c -o hello.bc (OK) llc -march=mips hello.bc -o hello.s (OK) gcc hello.s -o hello (does not work).

Great Job! If I use alternate-clang-driver, will I need mips-gcc still? I mean alternate-clang-driver use as&ld directly or by calling gcc?
