LLVM did not, and was not ever likely to generate correct code for those architecture versions so their presence was misleading. * Added codegen support for the complex arithmetic instructions in MVE. +* Added Armv4 and Armv4T compatible thunks. LLD will no longer generate BX + instructions for Armv4 or BLX instructions for either Armv4 or Armv4T. Armv4T + is now fully supported. +* Added compiler-rt builtins support for Armv4T, Armv5TE and Armv6. Changes to the AVR Backend -------------------------- -- 2.7.4
