This patch teaches ias for mips to handle expressions such as (8*4)+(8*31)($sp). Such expression typically occur from the expansion of multiple macro definitions. This partially resolves PR/30383. Thanks to Sean Bruno for reporting the issue! Reviewers: zoran.jovanovic, vkalintiris Differential Revision: https://reviews.llvm.org/D24667 llvm-svn: 284485
