llvm/llvm/test/tools/llvm-lib/use-paths.test

llvm-lib should behave like "link.exe /lib" and use relative paths to describe
archive members.

First, get in a clean working directory.
RUN: rm -rf %t && mkdir -p %t && cd %t

Make foo/a.obj and foo/b.obj.
RUN: mkdir foo
RUN: llvm-mc -triple=x86_64-pc-windows-msvc -filetype=obj -o foo/a.obj %S/Inputs/a.s
RUN: llvm-mc -triple=x86_64-pc-windows-msvc -filetype=obj -o foo/b.obj %S/Inputs/b.s

RUN: llvm-lib -out:foo.lib foo/a.obj foo/b.obj
RUN: llvm-ar t foo.lib | FileCheck %s

FIXME: We should probably use backslashes on Windows to better match MSVC tools.
CHECK: foo/b.obj
CHECK: foo/a.obj

Do it again with absolute paths and see that we get something.
RUN: llvm-lib -out:foo.lib %t/foo/a.obj %t/foo/b.obj
RUN: llvm-ar t foo.lib | FileCheck %s --check-prefix=ABS

ABS: {{.*}}/foo/b.obj
ABS: {{.*}}/foo/a.obj
