[cfe-dev] Bug report requested by clang-3.9

[Genie Jhang via cfe-dev]

Hi.

I’m trying to check if llvm + clang with MCJIT backend supports the new system.
The system information is following.

========================================================
cpu      : FUJITSU SPARC64 XIfx
manufacture   : 4 (Fujitsu)
impl      : 12
mask      : 17
serial      : 0
fpu      : FUJITSU SPARC64 XIfx
pmu      : SPARC64XIfx
prom      : CPUFW-1.5.0
type      : s64fx
ncpus probed   : 34
ncpus active   : 34
L2$ size   : 12288 KB

uname -m = s64fx
uname -r = 2.6.32
uname -s = Linux
uname -v = #2 SMP Wed Dec 2 15:57:26 JST 2015
========================================================

It started from installing ROOT software in the system
https://root.cern.ch/phpBB3/viewtopic.php?p=94086#p94086

I was told to compile a simple test code with llvm + clang compiled on the system.

#include <vector>
extern "C" in printf(const char*,...);
std::vector<int> v{12,13,14};
int main(int, char*[]) {
  printf("vector size: %d\n", (int)v.size());
  return 0;
}

with the following command

clang++ -x c++ -std=c++11 -Xclang -emit-llvm - -o jittest.cxx | lli -jit-kind=orc-mcjit -

and then I got the following.
For your information, because I config.guess doesn’t recognize the system, I changed the GetHostTarget.cmake a little bit
to recognize the system as sparc64-unknown-linux-gnu.

Any idea on this?

Thank you in advance.
