Can Clang accept LLVM IR or bitcode via pipe?
clang, llvm-ir
Solution
The language flag you're looking for is `ir`. For example:
clang hello_world.c -S -emit-llvm -o - | clang -x ir -o hello_world -
works for me (clang version 3.5, trunk 200156).
Problem
Clang can accept source files through a pipe if a language is specified with the `-x` flag. ``` cat hello_world.c | clang -x c -o hello_world ``` Clang can also compile LLVM IR and bitcode to object files ``` clang hello_world.c -S -emit-llvm && clang -o hello_world hello_world.ll ``` I want to compile LLVM IR or bitcode passed via a pipe. However, I can't find any documentation on exactly what parameters the `-x` option accepts. I can use `c`, `c++`, but clang doesn't recognize `llvm` or `bitcode`. What can I give to `-x` so Clang will accept IR or bitcode?
