similar to: [LLVMdev] Generate code for ARM Cortex m0, m3, and m4.

Hi Jan, For Cortex-M0, you should probably use the armv6m string in the target triple. For M3 and M4 you need to use the thumbv7m arch string, -mthumb won't be necessary.

I've got a trivial fix for this problem, and another one which manifests when thumb is given without an explicit CPU. I'll start pushing it through our submissions process.

Thanks Bernie, Feel free to assign yourself to the bug report, just so we know someone is working on it. cheers, -renato On 14 October 2013 17:38, Bernard Ogden <bogden.dev at gmail.com> wrote: > I've got a trivial fix for this problem, and another one which manifests > when thumb is given without an explicit CPU.

Hi, I'm building LLVM on Mac OS 10.10 and I'm having trouble making LTO work. The system linker dumps the following information when I executed "ld -v" @(#)PROGRAM:ld PROJECT:ld64-241.9 configured to support archs: armv6 armv7 armv7s arm64 i386 x86_64 x86_64h armv6m armv7m armv7em LTO support using: LLVM version 3.4.2 which tells me that it is correctly pointing to the LLVM

Ok, and what's about -mthumb then? -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

You can also try -mcpu=cortex-m3, or try -ccc-host-triple armv7m-none-gnueabi (or -eabi), and possibly

Hi, For a certain type of analysis I generate inline assembly which I insert into the LLVM IR code. This inline assembly code contains labels that should not be duplicated. Problem is that the tail duplication pass duplicates code. It checks isNotDuplicatable on a machine instruction however there is no such a flag on an IR instruction that I could set. Is there a way to tell in an IR pass that

Ah, yes! Try: $ clang -ccc-host-triple thumbv7m-none-gnueabi testReference.cpp -c Cross

Now that there is good thumb2 support in the ARM backend, would someone please add "cortex-m3" to the "-march" list for the ARM backend. This should produce pure thumb2 only code. At some point, when the subsets are public, "cortex-m1" and "cortex-m0" should also be added. thanks, bagel

Here is a one-line patch to support the cortex-m3. For those who plan the features for ARM, the new cortex-m0 implements only a subset of the Thumb2 instructions. I still have yet to see a document that details what's in the subset. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: arm.diff URL:

Dear LLVM developers, Hello, I'm trying to find a way of cross-compiling my c code against Baremetal Cortex-M device (so target triple will be arm-none-eabi) only using LLVM/Clang, and not using anything from GNU (ld or libc). I'm doing this to know which one of LLVM/clang and GCC produces smaller flash image size because saving flash is a big deal in our projects. 1) When I just follow

Hi, What would be the proper syntax in a C file, using inline assembly, to load a immediate value into an ARM register using clang & integrated assembler? The following syntax is rejected by LLVM: // clang -target armv7em-none-eabi -mthumb #define CONSTANT 0x1234 void __attribute__((naked)) foo(void) { asm volatile ( "ldr r0, =%0 \n"

H i, all! First of all, I'd like to apologize for my poor English. It's for years I don't use it. This is a R-version of a function I wrote a long ago for my HP48 calculator. It works with the binary expression of the power and just need to duplicate the mem used by X. Hope this helps. mtx.exp<-function(X,n) #Function to calculate the n-th power of a matrix X; { phi <-

Hello everyone, For a private project I would like to make a new Internet Intercom device (for my kids and me). At the moment I use a separate DSP with Ogg/Vorbis (VS1053) but I like a challenge ;-) Is a eg. ST32F10x (cortex m3) or a new ST32F40x (cortex m4) powerful enough to do encoding and decoding ? Any existing projects to learn from? Thanks for your time, Edwin van den Oetelaar
