From b040c2cbafe3da7f68872322274a421e4b51371e Mon Sep 17 00:00:00 2001 From: Miod Vallat Date: Wed, 19 Aug 2009 19:47:54 +0000 Subject: would provide inline version of a few of the functions traditionnaly found in libkern. However, the memcmp() flavour would behave as bcmp() with only two possible return values: zero and positive non-zero. This broke the name cache RB trees which now rely upon proper memcmp() semantics(negative value, zero, or positive value). Just give up on these macros and provide the same code as libc, in libkern. As a side effect, this no longer uses the cmpc3 instruction, which is not implemented and requires (slow) kernel emulation, on the original uVax. --- sys/lib/libkern/arch/vax/bcmp.S | 57 ++++++++++++++++++++++++- sys/lib/libkern/arch/vax/bcopy.S | 72 ++++++++++++++++++++++++++++++- sys/lib/libkern/arch/vax/bzero.S | 47 +++++++++++++++++++- sys/lib/libkern/arch/vax/memcmp.S | 65 ++++++++++++++++++++++++++++ sys/lib/libkern/arch/vax/memcpy.S | 86 +++++++++++++++++++++++++++++++++++++ sys/lib/libkern/arch/vax/memmove.S | 87 +++++++++++++++++++++++++++++++++++++- sys/lib/libkern/arch/vax/memset.S | 48 +++++++++++++++++++++ sys/lib/libkern/arch/vax/ovbcopy.S | 2 +- 8 files changed, 459 insertions(+), 5 deletions(-) create mode 100644 sys/lib/libkern/arch/vax/memcmp.S create mode 100644 sys/lib/libkern/arch/vax/memcpy.S create mode 100644 sys/lib/libkern/arch/vax/memset.S (limited to 'sys/lib/libkern') diff --git a/sys/lib/libkern/arch/vax/bcmp.S b/sys/lib/libkern/arch/vax/bcmp.S index 33ba5c2da5c..1c480988ecb 100644 --- a/sys/lib/libkern/arch/vax/bcmp.S +++ b/sys/lib/libkern/arch/vax/bcmp.S @@ -1 +1,56 @@ -/* No code here since kernel impliments this itself */ +/* $OpenBSD: bcmp.S,v 1.3 2009/08/19 19:47:53 miod Exp $ */ +/* + * Copyright (c) 1983, 1993 + * The Regents of the University of California.
