Summary: ARM allocates invalid registers for VFPv3-D16
(possibly allocating D16, D17 etc.)
Product: tools
Version: trunk
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: llc

The ARM backend may end up allocating registers D16 to D31 when "-mattr=+vfp3"
is specified. However, this will not work for hardware that only supports 16
registers.
Attached is a possible fix, adding a new flag to support -"mattr=+vfp3,+d16".
