Instead of doing a linear search through the insn_table for each instruction, use the opcode as direct index into the table. This will give constant time lookup performance as the number of supported opcodes increases. Make the tables const as they are only ever read. For uasm-mips.c sort the table alphabetically, and remove duplicate entries, uasm-micromips.c was already sorted and duplicate free. There is a small savings in object size as struct insn loses a field: $ size arch/mips/mm/uasm-mips.o arch/mips/mm/uasm-mips.o.save text data bss dec hex filename 10040 0 0 10040 2738 arch/mips/mm/uasm-mips.o 9240 1120 0 10360 2878 arch/mips/mm/uasm-mips.o.save Signed-off-by: David Daney <david.daney@cavium.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Matt Redfearn <matt.redfearn@imgtec.com> Cc: netdev@vger.kernel.org Cc: linux-kernel@vger.kernel.org Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/16365/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> |

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
