            Bug ID: 17277
           Summary: Teach converts from gcc about -I vs. -Wa,-I
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: fischman at chromium.org
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Programmers used to gcc's ways attempt to use -Wa,-I... to pass include paths
to the assembler (equiv., -Xassembler -I...).  This is useless in clang, where
they should simply say -I...

It would be nice if instead of merely saying something like:
clang: error: unsupported argument '-Igen/third_party/libvpx' to option
'Xassembler'
clang taught the programmer how to do it right.
