[mips][mips16] MIPS16 is not a CPU/Architecture but is an ASE. Summary: The -mcpu=mips16 option caused the Integrated Assembler to crash because it couldn't figure out the architecture revision number to write to the .MIPS.abiflags section. This CPU definition has been removed because, like microMIPS, MIPS16 is an ASE to a base architecture. Reviewers: vkalintiris Subscribers: rkotler, llvm-commits, dsanders Differential Revision: http://reviews.llvm.org/D13656 llvm-svn: 250407

; RUN: llc -mtriple=mipsel-linux-gnu -march=mipsel -mattr=mips16 -relocation-model=pic < %s | FileCheck %s -check-prefix=PIC
Next step in Mips16 prologue/epilogue cleanup. Save S2(reg 18) only when we are calling floating point stubs that have a return value of float or complex. Some more work to make this better but this is the first step. llvm-svn: 196921

Last change for mips16 prolog/epilog cleanup and optimization. Some tiny cosmetic code changes to follow. Because of the wide ranging nature of the patch a full 24 test cycle was needed to check against regression. This was the smallest patch I could make to progress from the earlier ones in the series. llvm-svn: 197350
