svn commit: r250138 - in head/sys/mips: include mips

Warner Losh imp at FreeBSD.org
Wed May 1 06:57:47 UTC 2013


Author: imp
Date: Wed May  1 06:57:46 2013
New Revision: 250138
URL: http://svnweb.freebsd.org/changeset/base/250138

Log:
  Don't include asm.h in non-asm files.
  Remove #define to get kludges that asm.h used to define
  Move clever macros to access assembler instructions to trap.c
  Remove __ASSEMBLER__ ifdefs in regdef.h: they aren't needed anymore.

Modified:
  head/sys/mips/include/asm.h
  head/sys/mips/include/regdef.h
  head/sys/mips/mips/db_interface.c
  head/sys/mips/mips/trap.c
