While writing the previous patch, I noticed that we're not consistent with the (C) in the copyright header. The maintainers manual prefers having it, though also says it's optional. We have over 10x more files with (C) than without in gdb's code, so I spent a few minutes grepping and fixing. Funny enough, the testsuite has it backwards. I'll leave that for another time. gdb/ 2013-02-12 Pedro Alves <palves@redhat.com> * amd64-darwin-tdep.c: Add (C) after Copyright. * cli/cli-cmds.h: Ditto. * cli/cli-decode.c: Ditto. * cli/cli-decode.h: Ditto. * cli/cli-dump.c: Ditto. * cli/cli-dump.h: Ditto. * cli/cli-interp.c: Ditto. * cli/cli-logging.c: Ditto. * cli/cli-script.c: Ditto. * cli/cli-script.h: Ditto. * cli/cli-setshow.c: Ditto. * cli/cli-setshow.h: Ditto. * cli/cli-utils.c: Ditto. * cli/cli-utils.h: Ditto. * config/alpha/nm-osf3.h: Ditto. * config/djgpp/djconfig.sh: Ditto. * config/i386/nm-fbsd.h: Ditto. * config/i386/nm-i386gnu.h: Ditto. * config/nm-linux.h: Ditto. * config/nm-nto.h: Ditto. * config/rs6000/nm-rs6000.h: Ditto. * config/sparc/nm-sol2.h: Ditto. * darwin-nat-info.c: Ditto. * dfp.c: Ditto. * dfp.h: Ditto. * gdb-demangle.h: Ditto. * i386-darwin-nat.c: Ditto. * i386-darwin-tdep.c: Ditto. * linux-fork.h: Ditto. * m32c-tdep.c: Ditto. * microblaze-linux-tdep.c: Ditto. * microblaze-rom.c: Ditto. * microblaze-tdep.c: Ditto. * microblaze-tdep.h: Ditto. * mips-linux-tdep.h: Ditto. * ppc-ravenscar-thread.c: Ditto. * ppc-ravenscar-thread.h: Ditto. * prologue-value.c: Ditto. * prologue-value.h: Ditto. * ravenscar-thread.c: Ditto. * ravenscar-thread.h: Ditto. * sparc-ravenscar-thread.c: Ditto. * sparc-ravenscar-thread.h: Ditto. * tilegx-linux-tdep.c: Ditto. * unwind_stop_reasons.def: Ditto. * windows-nat.h: Ditto. * xtensa-linux-tdep.c: Ditto. * xtensa-xtregs.c: Ditto. * regformats/regdat.sh: Ditto. * regformats/regdef.h: Ditto. gdb/gdbserver/ 2013-02-12 Pedro Alves <palves@redhat.com> * linux-xtensa-low.c: Ditto. * xtensa-xtregs.c: Ditto.
