Pull in r216989 from upstream llvm trunk (by Renato Golin):

MFV: Only emit movw on ARMv6T2+

Missing test from r216989
|
|
|
|
Building for the FreeBSD default target ARMv6 was emitting movw ASM on certain
|
|
test cases (found building qmake4/5 for ARM). Don't do that, moreover, the AS
|
|
in base doesn't understand this instruction for this target. One would need
|
|
to use --integrated-as to get this to build if desired.
|
|
|
|
Introduced here: http://svnweb.freebsd.org/changeset/base/271025
