[cfe-dev] Compiling Libcpp for a Baremetal Toolchain.

Hi All,

I am building a cross-compiler for MIPSr2 which has the following
components: Clang-3.1 for preprocessing, compiling, optimizing; Binutils-2.22
for assembling and linking; Newlib-1.20.0 as the standard C library
implementation. I modified the Clang Driver and currently can run C
programs on a MIPS-GDB simulator I built using a MIPS target triple option
to Clang. I would like to use Libcpp as the C++ library implementation for
this toolchain. Is there a way to disable the libcpp -> pthread
dependencies as my baremetal toolchain currently does not support a
threading library. In the long term are there any suggestions on what kind
of a thread library I should use for compiling Libcpp? What would be a good
place to look at how to port these dependencies? I really would like to run
C++ programs using this toolchain and look forward to write code using C++
lambdas. Let me know.
