Make sure you are running a clean build.
If you are then follow the suggested instructions in the error message
and file a bugreport for your toolchain to codesourcery.

/home/prasanth/LLVM_ARM/llvm-with-armgcc433/llvm/lib/Analysis/LoopPass.cpp:100:
internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

Hi,

I can able to compile LLVM using armgcc_4.3.3 (codesourcery2009q1..).. but
when i tried to run it on target it shows GCC 4.3.0 version not found. So i
copied the runtime libraries (libc.so and libgcc_s.so) from the toolchain to
the target and exported its path in LD_LIBRARY_PATH. But when i tried to run
any llvm tools on target its crashing with Segmentation fault. What could be
the problem for this.

My target kernel and rootfs are compiled with armgcc-4.2.1... so should i
need to compile the kernel and rootfs with armgcc-4.3.3?

If i want to use arm-toolchain-4.2.1 , what should i do for clearing the
instruction cache call in lib/System/Memory.cpp?

Thanks and Regards,
Prasanth J

Impossible to know without debugging. whats the backtrace when running
the program from inside the gnu debugger gdb?
and what tools did you run.

What command did you run that caused the crash?

What are the output from
llc -version
and
lli -version
?

Probably not needed.

You have to implement it using inline assembler for GCC 4.2.1 and below
to work.
You can check the gcc sources to see how __clear_cache got implemeted in
gcc 4.3.3 or check the arm reference manual (ARM ARM):
http://www.arm.com/miscPDFs/14128.pdf

You can also look how other projects have solved this problem in the past:
http://www.complang.tuwien.ac.at/viewcvs/cgi-bin/viewcvs.cgi/gforth/arch/arm/cacheflush-linux.c?rev=1.4
Here the clear cache are implemented using inline asm and a linux
systemcall to be usable with gcc 4.2.1.
