Summary: Use the filepath used to open the archive member as the archive member name instead of the file basename. This path might be absolute or relative. This is important because the archive member name will show up in the PDB, and we want our PDBs to look as much like MSVC's as possible. This also helps avoid an issue in our PDB module descriptor writing code, which assumes that all module names are unique. Relative paths still aren't guaranteed to be unique, but they're much better than basenames, which definitely aren't unique.

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