* [MSP430] Generate EABI-compliant libcallsVadzim Dambrouski2017-05-111-0/+43
Updates the MSP430 target to generate EABI-compatible libcall names. As a byproduct, adjusts the hardware multiplier options available in the MSP430 target, adds support for promotion of the ISD::MUL operation for 8-bit integers, and correctly marks R11 as used by call instructions. Patch by Andrew Wygle. Differential Revision: https://reviews.llvm.org/D32676 llvm-svn: 302820
