Bradley Smith	960ce2aafa	[ARM] Fix subtarget feature set truncation when using .cpu directive This is a bug that was caused due to storing the feature bitset in a 32-bit variable when it is a 64-bit mask, discarding the top half of the feature set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228151 91177308-0d34-0410-b5e6-96231b3b80d8	2015-02-04 16:23:24 +00:00
Roman Divacky	2664ea938f	Introduce CPUStringIsValid() into MCSubtargetInfo and use it for ARM .cpu parsing. Previously .cpu directive in ARM assembler didnt switch to the new CPU and therefore acted as a nop. This implemented real action for .cpu and eg. allows to assembler FreeBSD kernel with -integrated-as. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223147 91177308-0d34-0410-b5e6-96231b3b80d8	2014-12-02 20:03:22 +00:00

[ARM] Fix subtarget feature set truncation when using .cpu directive

This is a bug that was caused due to storing the feature bitset in a 32-bit
variable when it is a 64-bit mask, discarding the top half of the feature set.

Introduce CPUStringIsValid() into MCSubtargetInfo and use it for ARM .cpu parsing.

Previously .cpu directive in ARM assembler didnt switch to the new CPU and
therefore acted as a nop. This implemented real action for .cpu and eg. 
allows to assembler FreeBSD kernel with -integrated-as.
