similar to: [LLVMdev] new target as 3rd party project

No, adding new target requires changes to auto* stuff to allow llvm- config to "catch" things. --- With best regards, Anton Korobeynikov

Anton, I've got a new target which i've developed outside the tree. I needed to make a couple of minor modifications to the autoconf scripts to get it to work, but once done, it works just fine. Paul, when I get in to work I'll take a look to let you know just what to do. Justin On Sun, Apr 19, 2009 at 9:48 PM, Anton Korobeynikov <anton at korobeynikov.info > wrote: >

Hi everyone, inline asm code is like below: void test(unsigned short a) { asm("myinstr my16bitreg, %0"::"r"(a)); } I want it generate instruction "myinstr my16bitreg, r15" I execute llc test.bc -march = msp430 -o test.s then it reports "LLVM ERROR: Couldn't allocate input reg for constraint 'r' !" What's the reason?

Also, the Fortran grammar is not the simplest (or, rather - straightforward one). So this certainly looks too big for GSoC. Though, it

Can you please tell me what should I do at this point? How to get the standard C library for ARM around? I also tried to build  http://llvm.org/svn/llvm-project/llvm/trunk/utils/crosstool/ in CYGWIN. However, my LLVM building was failed when I run the script. I am in dilemma what steps i should follow. Please help me. Thanks a lot Akramul --- On Tue, 4/1/11, Anton Korobeynikov <anton at

Hi! We are running llvm jit x86 on MS Visual Studio 2005. It seems there is a bug in asm code in function X86CompilationCallback in file X86JITInfo.cpp. Current code sets stack pointer to invalid value in instruction "and esp, 16". Depending on current stack pointer value it sometimes overwrites ecx and edx registers with next three lines. We have fixed this problem by changing this

Hi everyone, I practice writing target description file with MSP430 reference. I add a multiply-and-add instruction as below: let isTwoAddress=1 in { def MULADD:Pseudo<(out GR16:$dst), (ins GR16:$src1, GR16:$src2, GR16:$src3), "muladd\t{$dst, $src2, $src3}", [(set GR16:$dst, (add GR16:$src1, (mul GR16:$src2,

Who is a code owner for MSP430 target? I know that a lot of work on this target is done by Anton Korobeynikov (aka asl) but he is not listed as a code owner in CODE_OWNERS.TXT. I would like to get my D20162 reviewed, but I don't know who I can add as a reviewer.

Hi, I agree that creating a complete Fortran compiler is a huge effort. But what about approaching it from a test driven development perspective? We start with a few small Fortran programs as "test cases". The GSoC task then gives the task as getting test case 1 to work. We could also apply this of "lfort". Determine a test case that currently fails on lfort, and ask the GSoC

> Can you please tell me what should I do at this point? How to get the standard C library for ARM around? The best thing is to grab some description how to build "normal" gcc for your target and make sure all the steps described there will be ok. After this you can substitute normal gcc with llvm-gcc and start the same scenario from scratch. I believe this is the best way how the

The "target > datalayout" information is purely a hint to the optimizers. My experience this far has been mainly with using llvm-gcc and llvmc,

Most probably you will need to write a special hook to commute this instruction. However, everything depends on your target (e.g. if there is an output register tied to one of the input). > *** Another question: Why set isCommutable = 1 in
