Summary: Previously the method would simply return false, causing every single inline assembly constraint to trigger a compile error. This adds inline assembly constraint support for the AVR target. This patch is derived from the code in AVRISelLowering::getConstraintType. More details can be found on the AVR-GCC reference wiki http://www.nongnu.org/avr-libc/user-manual/inline_asm.html Reviewers: jroelofs, asl Reviewed By: asl Subscribers: asl, ahatanak, saaadhu, cfe-commits Differential Revision: https://reviews.llvm.org/D28344 llvm-svn: 294176
