Is it possible to use LLVM-assembly directly?

There appears to be an LLVM assembler.

llvm-as is the LLVM assembler. It reads a file containing human-readable LLVM assembly language, translates it to LLVM bitcode, and writes the result into a file or to standard output.

The static compiler, which accepts LLVM Assembly:

Quick setup: (For llvm 3.4.0 .ll files on windows)

advanced text editor from https://notepad-plus-plus.org/

llvm binaries from https://github.com/CRogers/LLVM-Windows-Binaries

hello.ll as "UTF-8 without BOM" (This code is in llvm 3.4.0 format):

@msg = internal constant [13 x i8] c"Hello World!\00"
declare i32 @puts(i8*)
define i32 @main() {
    call i32 @puts(i8* getelementptr inbounds ([13 x i8]* @msg, i32 0, i32 0))
    ret i32 0
}

In command prompt:

lli hello.ll

Quick setup: (For llvm 3.8.0 .ll files on windows)

advanced text editor from https://notepad-plus-plus.org/

clang binaries from: http://llvm.org/releases/download.html#3.8.0

hello.ll as "UTF-8 without BOM" (This code is in llvm 3.8.0 format):

@msg = internal constant [13 x i8] c"Hello World!\00"
declare i32 @puts(i8*)
define i32 @main() {
    call i32 @puts(i8* getelementptr inbounds ([13 x i8], [13 x i8]* @msg, i32 0, i32 0))
    ret i32 0
}

In command prompt:

clang hello.ll -o hello.exe
hello.exe

Or as a single command:

clang hello.ll -o hello.exe & hello.exe

Errors about char16_t, u16String, etc means clang needs: -fms-compatibility-version=19
