+# --------------------
+# 01f,09oct12,jdw  Add support for VFP flags
+# 01e,20dec11,jdw  Fix COMMON_COMPILER to use defs.diab (WIND00238985)
+# 01d,20oct10,m_h  Workaround WIND00232992 with -Xkill-reorder=0x2000000
+# 01c,30jun10,m_h  Vector Floating Point Support
+# 01b,28jun10,m_h  Thumb-2 reorder workaround
+# 01a,14jun10,m_h  created from make.ARMARCH7diab
