llvm dev - Jun 2011 - [LLVMdev] llvm compilation of libc?

Hello,

I'm wondering if anyone had any success (even a small amount) compiling any
variant of libc to llvm bitcode?

I would recommend Newlib.  It's easy to configure and compile using Clang.

Hi Xi,

How did you compile it with clang? I ran into problems:

clang -emit-llvm -DPACKAGE_NAME=\"newlib\"
-DPACKAGE_TARNAME=\"newlib\"
-DPACKAGE_VERSION=\"1.19.0\" -DPACKAGE_STRING=\"newlib\
1.19.0\"
-DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -I.
-DMISSING_SYSCALL_NAMES
-fno-builtin     -DMISSING_SYSCALL_NAMES -fno-builtin   -O2 -c -o
lib_a-memcpy.o `test -f 'memcpy.S' || echo './'`memcpy.S
