<pre>I'd like to specify another resource-dir in clang-cl. `-Xclang -resource-dir
-Xclang <some directory>` does not work.
When I set -Xclang -resource-dir -Xclang D:\tmp\t, I expect clang-cl contains
D:\tmp\t\include as system include directory.
However, it doesn't.
When I set -resource-dir /tmp/t in Linux clang, it contains /tmp/t/include as
system include directory.
Looking at -### output, -resource-dir appears two times, and the first one is
used.
Repro:
Current working directory is D:\tmp
D:\tmp>type D:\tmp\t\include\A.h
#define A 100
#define B 100
D:\tmp>type test2.cpp
#include <A.h>
int main() {
return A + B;
}
D:\tmp>"D:\src\chromium_clang\src\third_party\llvm-build\Release+Asserts\bin\cla
ng-cl.exe" -Xclang -resource-dir -Xclang D:\tmp\t test2.cpp
test2.cpp(1,10): fatal error: 'A.h' file not found
#include <A.h>

1 error generated.
