*From*: cgd at broadcom dot com*To*: gdb-patches at sources dot redhat dot com*Date*: 09 Feb 2002 23:25:54 -0800*Subject*: [PATCH RFA] fix some sim spelling errors.

So, I've started looking at 'sim' again... Anyway, while doing so, I noticed a bunch of spelling errors that were just too obvious to ignore... 8-) Any objections to the following? I didn't fix things which i thought might have been valid spellings in, uh, a different part of the world or which the dictionary i consulted considered acceptable (but less-used or less-desirable), even if ispell or spell whined about them. 8-) I'd normally call this an obvious patch, but, well, some might see this as undesirable because it changes the files. So, i figured I'd ask first. If this is OK, i'll call future similar changes obvious. chris =================================================================== [sim/common/ChangeLog] 2002-02-09 Chris Demetriou <cgd@broadcom.com> * callback.c: Fix some spelling errors. * hw-device.h: Likewise. * hw-tree.c: Likewise. * sim-abort.c: Likewise. * sim-alu.h: Likewise. * sim-core.h: Likewise. * sim-events.c: Likewise. * sim-events.h: Likewise. * sim-fpu.h: Likewise. * sim-profile.h: Likewise. * sim-utils.c: Likewise.
