After a recent upstream pull, my builds for ARM thumbv7 suddenly fail with messages like: error: instruction requires: arm-mode 21 uxtah r6, r0, r6 I use llc with -mtriple=thumbv7-unknown-unknown and llvm-mc with -triple=thumbv7-unknown-unkown. What's the right way to generate thumbv7 binaries? Thanks, -steve

Thanks! I also found test/CodeGen/ARM/ghc-tcreturn-lowered.ll, which tests only for thumbv7-eabi, so, i tried a few more variations: [x] arm64-apple-ios [x] arm64-apple-ios7.0.0 [x] arm64-apple-darwin [x] armv7-apple [x] thumbv7-apple [x] thumbv7-apple-darwin [x] i386-apple-ios [x] i386-apple-darwin [f] thumbv7-apple-ios [f] thumbv7-apple-ios7.0.0 [f] armv7-apple-ios I’ve also just build a

Hi James, Thanks for the answer, can you elaborate on difference between thumb, thumb2, ARM, thumbv7. I'm a bit lost right now. When specifying thumbv7 llc will generate thumb only code, not thumb2 ?

Hi Seb, The ARM instruction set is a fixed-width 32-bit instruction set that has been around since the early days of ARM. Modern (armv4t onwards) cores mostly have another instruction set that can be used in tandem, the "thumb" instruction set. This is a variable width (16 or 32 bit) instruction set that provides a subset of the ARM instruction set and was intended to provide the

Thanks Saleem, Nick. I will try with the latest code and share the results. Though, just curious if I need to really use clang to generate the object file and the current steps won't work? I ask because using .c file was only an illustration. For my project the IR is not generated from .c files or clang. Thanks, Daman Sent from my phone On 08-Jun-2014, at 11:00 am, "Saleem

Hi James, Thanks for the answer, for Cortex-A9 would you recommend to generate thumb2 code or ARM code ? What would be the best performance wise ?

When I use llvm-mc’s ‘-show-encoding’, it only goes as far as printing “fixups”: $ echo -e "adr r0, lbl\nnop\nlbl:" | llvm-mc -triple=thumbv7 -show-encoding Outputs: @ encoding: [A,0xa0] @ fixup A – offset: 0, value: lbl, kind: fixup_thumb_adr_pcrel_10 To find out that it is encoded as 0xa001, I can do: $ echo -e "adr r0, lbl\nnop\nlbl:" | llvm-mc

I am talking about Windows Mobile 8 and 8.1 and not CE. Not sure though that the Windows 8 (ARM NT) is similar to Windows Mobile 8 platform. I used the following command to generate the obj file Llc.exe -mtriple=thumbv7-windows -filetype=obj <some_name>.bc The object file generated in the above object doesn't get linked when I try to link it with the windows mobile library as it

Thanks a lot Saleem, The issue is fixed and a simple app works fine now. -Daman On 08/06/14 12:57 pm, "Nick Lewycky" <nicholas at mxc.ca> wrote: >Damanjit Singh wrote: >> Thanks Saleem, Nick. >> >> I will try with the latest code and share the results. >> >> Though, just curious if I need to really use clang to generate the >> object file

I am not using llvm tools, but sources and directly calling into relevant LLVM classes and methods.

Hi *, in the process of improving the ios experience with ghc, I ran into the following issue: the produced llvm code[1] compiles for `armv7-apple-darwin`, unless optimization level is 0, however it fails to compile at all for `armv7-apple-ios`. I was able to reduce the produced code, while retaining the compilation issue on `armv7-apple-ios` to the following sample case: —————————————————————

Hi, Is there support available in llc to convert llvm bytecode to Windows Mobile binary? I have tried triples like arm-pc-win32 , thumbv7-window ... but the object file generated is not getting linked to the windows native project. Any pointers will be greatly appreciated?

Hi Saleem, I have a similar situation - I'd appreciate your inputs on it. I noticed that the obj file generated using llvm does not contain "thumb" instructions. I suspect that is what is causing runtime crash for me. Here's what I've tried - Start with a.c (on my linux machine where I have llvm/clang built as of yesterday) int add(int i, int j) {int k

Hello everyone At EuroLLVM I presented some testing work we have been doing on improving correctness of the MC Layer for ARM. There seemed to be interest from the community in seeing the results of this test suite. Background ----------- We are using a test suite, called MC Hammer, that compares MC with an ARM in-house implementation of the same functionality. The test space for this suite is

Hi Saleem, Though a simple app works great I am facing few issues trying to link a slightly complex object file, generated via LLVM, with some libs generated via Visual Studio - 1. Seems IMAGE_SCN_MEM_16BIT is only written for the the first header in the COFF file, thus functions in other headers (if you are using function sections) don’t work. I was able to workaround this by forcing this entry

Hi, many of the bots on http://lab.llvm.org:8011/console don't do anything in their compile phase, even if they should. For example, these bots all don't do anything in their compile phase in any builds, even if they should: http://lab.llvm.org:8011/builders/clang-x64-ninja-win7/ http://lab.llvm.org:8011/builders/clang-ppc64be-linux

Hi all, I was wondering if 'llc' is able to generate 'it' instruction for ARM Cortex-A9 target ? Thanks for your answers Seb
