Summary: This patch adds support for using the "interrupt" attribute on Mips for interrupt handling functions. At this time only mips32r2+ with the o32 ABI with the static relocation model is supported. Unsupported configurations will be rejected Patch by Simon Dardis (+ clang-format & some trivial changes to follow the LLVM coding standards by me). Reviewers: mpf, dsanders Subscribers: dsanders, vkalintiris, llvm-commits Differential Revision: http://reviews.llvm.org/D10768 llvm-svn: 251286
