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
Assignee: unassignedclangb...@nondot.org
Reporter: t.poechtra...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
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?
