Bug ID: 46875
Summary: -B options are not translated into -L options for the
linker
Product: clang
Version: 10.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Driver
Assignee: unassignedclangb...@nondot.org
Reporter: rixr...@gmail.com
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,

Steps to reproduce:
* Create a dummy file, which can be linked, e.g.
int main() { return 0; }
* Execute:
> $ mkdir ADD_ME_AS-L
> $ clang++ main.cpp -B ADD_ME_AS-L --verbose 2>&1 | grep ADD_ME_AS-L
> --color=auto
> <no output>
> $ g++ main.cpp -B ADD_ME_AS-L --verbose 2>&1 | grep ADD_ME_AS-L --color=auto
> <outputs line where LD is executed with -LADD_ME_AS-L option>
According to the docs:
-B prefixes that effectively specify directory names also apply to libraries in
the linker, because the compiler translates these options into -L options for
the linker.
But clang does not do that.
