...RM. What other way do you suggest for duplicating since you mentioned I shouldn't rely on duplication the way I am doing it? Thanks a lot. I really appreciate your help.

...intrinsic call between the similar two instructions which either I'll remove or convert to nop in codegen. Does that kind of seem appropriate for the purpose here?

Hello, I am duplicating few instructions in a basic block and splitting it. The following is an example. bb: ; preds = %bb1 %0 = load i32* %i, align 4 %1 = getelementptr inbounds [100 x i32]* %a, i32 0, i32 %0 store i32 0, i32* %1, align 4 %2 = load i32* %i, align 4 %3 = getelementptr inbounds [100 x i32]* %last_added, i32 0, i32 %2 store

...utation (same as visible in x86 asm e.g. adding the one twice) for ARM. Is there a way I can achieve it? Does the problem make more sense now? Thank you for your help.

Thanks for your reply. I have a normal (../configure --enable-profiling --disable-optimized --enable-assertions) llvm debug+profile+assert build. I am generating llvm-bitcode using following commands. llvm-gcc -DLINUX_i386 -DSPEC_CPU2000 -O3 -emit-llvm 186.crafty/src/valid.c -c -o 186.crafty/src/valid.bc --- llvm-link 186.crafty/src/*.bc -o 186.crafty/186.crafty.rel.bc and finally: llc

My source directory wasn't correct but now I have a correct test directory structure. $ls -1 ~/tmp/speccpu2000/benchspec/CINT2000/164.gzip/ data docs exe result run Spec src version I reconfigured the llvm with ../configure --prefix=/home/dskhudia/tmp/llvm-install --with-llvmgccdir=/home/dskhudia/tmp/llvm-install --with-externals=/home/dskhudia/tmp Now I can execute the make -C 164.gzip but I am getting the following error. /home/dskhudia/tmp/llvm-2.9/obj/projects/test-suite/../../../projects/test-suite/RunToolSafely.sh 500 /home/dskhudia...

Here is how I do it on x86-64 machine running Ubuntu-11.04: 1. install flex and bison 2. download arm-2011.03 from www.codesourcery.com and add to path (setenv PATH ${PATH}:/home/dskhudia/projects/arm-2011.03/bin) 3. mkdir llvm-gcc-obj; cd llvm-gcc-obj 4. ../llvm-gcc-4.2-2.9.source/configure --target=arm-none-linux-gnueabi --program-prefix=llvm- --enable-llvm=/home/dskhudia/projects/llvm-2.9/obj-arm --prefix=/home/dskhudia/projects/llvm-install-arm --with-sysroot=/home/dskhudia/pr...

Hi Duncan, Do you have sources also in the $LLVM_SRC_ROOT/projects/test-suite/External/SPEC/CINT2000/164.gzip? The following is content of above directory in my case. I have copied the CINT2000 sources in this directory manually. $ls -1 $LLVM_SRC_ROOT/projects/test-suite/External/SPEC/CINT2000/164.gzip 164.gzip.reference_output 164.gzip.reference_output.small compile_info compile_parms

Hi I am trying to cross compile llvm-gcc front for ARM target Followed below steps #../llvm-gcc-4.2-2.9.source/configure --program-prefix=llvm- --enable-llvm=/home/yuvraj/llvm/llvm-2.9 --enable-languages=c,c++ --target=arm-none-linux-gnueabi # make I am getting some kind of linker errors /opt/arm-2010.09/bin/arm-none-linux-gnueabi-ld: cannot find crtn.o: No such file or directory @ final

Thank you all for the inline assembly pointer. I have some macros (FD_ZERO, FD_SET) in benchmark code which comes from C library select (synchronous I/O multiplexing) and it does contain inline assembly. Is there a way the code containing such macros can work for ARM if compiled through llvm? Thanks Daya On Tue, Jun 14, 2011 at 3:02 PM, Duncan Sands <baldrick at free.fr> wrote: > Hi

Hi All, I am trying to configure llvm so with test-suite enabled. I have downloaded the test-suite. Spec 2000 benchmarks sources are plugged in speccpu2000 at $LLVM_SRC_ROOT/projects/test-suite-externals/speccpu2000/benchspec e.g.: 164.gzip dir is $LLVM_SRC_ROOT/projects/test-suite-externals/speccpu2000/benchspec/164.gzip My configure command is: ../configure --disable-optimized

Hello, I am getting the following error while generating code for arm using llc for one of the specint2000 benchmark. Though same works for x86 target. Command => llc -march=arm 186.crafty/186.crafty.rel.bc -o 186.crafty/186.crafty.m5arm.s Error => LLVM ERROR: Couldn't allocate output reg for constraint '{cx}'! Have anyone seen this before? Is there a work around for this?

Hi, Does anyone know how to fix the following error?
