            Bug ID: 24765
           Summary: '-arch armv6' generates code for armv7 instead of
                    armv6
           Product: clang
           Version: 3.7
          Hardware: PC
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

This only affects 3.7.
I have used the official 3.7.0 binaries from llvm.org for testing.

Clang 3.6 and trunk seem to do the right thing.

$ echo "int x; " | clang -target arm-apple-darwin -miphoneos-version-min=4.2.1
-arch arm64 -c -o- -xc - | file -
/dev/stdin: Mach-O 64-bit 64-bit architecture=12 object

$ echo "int x; " | clang -target arm-apple-darwin -miphoneos-version-min=4.2.1
-arch armv7s -c -o- -xc - | file -
/dev/stdin: Mach-O arm subarchitecture=11 object

$ echo "int x; " | clang -target arm-apple-darwin -miphoneos-version-min=4.2.1
-arch armv7 -c -o- -xc - | file -
/dev/stdin: Mach-O arm_v7 object

$ echo "int x; " | clang -target arm-apple-darwin -miphoneos-version-min=4.2.1
-arch armv6 -c -o- -xc - | file -
/dev/stdin: Mach-O arm_v7 object # Shouldn't this generate code for armv6, or
am I missing something here?
