ARMv6K is another layer between ARMV6 and ARMV6T2. This is the LLVM side of the changes. ARMV6 family LLVM implementation. +-------------------------------------+ | ARMV6 | +----------------+--------------------+ | ARMV6M (thumb) | ARMV6K (arm,thumb) | <- From ARMV6K and ARMV6M processors +----------------+--------------------+ have support for hint instructions | ARMV6T2 (arm,thumb,thumb2) | (SEV/WFE/WFI/NOP/YIELD). They can +-------------------------------------+ be either real or default to NOP. | ARMV7 (arm,thumb,thumb2) | The two processors also use +-------------------------------------+ different encoding for them. Patch by Vinicius Tinti. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232468 91177308-0d34-0410-b5e6-96231b3b80d8
