Hi all,
Can someone tell me how to import functions from shared libraries and use them in LLVM assembly

Hi Dylan,
If you have "import libraries", you may call them with general calling
conversions.
Without import libraries, for example;
declare dllimport i32 @foo(i32)
@quux = dllimport global i32
define i32 @bar() nounwind {
%a = load i32* @quux
%r = call i32 @foo(i32 %a)
ret i32 %r
}
.globl _bar
_bar:
subl $4, %esp
movl __imp__quux, %eax
movl (%eax), %eax
movl %eax, (%esp)
calll *__imp__foo
addl $4, %esp
ret
If you have clang or llvm-gcc, you can confirm outputs with
clang foo.c -S -emit-llvm -o foo.ll
clang foo.c -S -o foo.s
...Takumi
Doh!
