I am guessing that is what you meant by the

[LLVMdev] Compiling a raw binary with llvm/clang
Indeed ld does link it. The reason I am using llvm-ld, is for its unique
functionality.
I intend to link to object files together (created by cling), and link them
with llvm-ld.
The main feature that I am currently interested in is the ability to have
"inline functions" between two object files. This was basically impossible
with gcc.
Is there any way to make the raw binary with llvm?

[LLVMdev] Compiling a raw binary with llvm/clang
Hey,
The following code creates a raw binary (no ELF or PE.. just raw):
gcc -nostartfiles -c -o hello.o hello.c
ld -o hello1 hello.o --oformat binary
You can try the following code out with it:
void _start()
{
while(1);
}
The resulting raw binary is 5 bytes.
Now how do you do this in clang/llvm?
Apparently llvm-ld doesn't have a "--oformat binary" option.
Anybody know how to
