# Warning flags for compiling the kernel and components of the kernel.

# Note that the newly added -Wcast-qual is responsible for generating 
# most of the remaining warnings.  Warnings introduced with -Wall will
# also pop up, but are easier to fix.

CWARNFLAGS?=	-Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes \
		-Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual \

#
# The following flags are next up for working on:
#	-W
#
# When working on removing warnings from code, the `-Werror' flag should be
# of material assistance.

#
# On the alpha, make sure that we don't use floating-point registers and
# allow the use of EV56 instructions (only needed for low-level i/o).

Fixed comment and whitespace lossage in recent commits. The -W flag is not implied by -Wall as claimed by gcc.1. Adding it causes a measly 7193 new warnings for LINT, mostly for "unused parameter" and "comparison between signed and unsigned". 1999-01-29 10:57:18 +00:00			`# $Id: bsd.kern.mk,v 1.14 1999/01/29 06:22:19 dillon Exp $`
Oops, forgot to cvs add bsd.kern.mk. Centralized the definition of CWARNFLAGS into bsd.kern.mk. 1996-10-08 22:10:49 +00:00

Turned on -Wformat -fformat-extensions. -fformat-extensions requires a -current version of gcc. Without it, -Wformat would complain about all the nonstandard %[Dbrz] formats in the kernel. 1998-09-09 10:04:58 +00:00			`-fformat-extensions -ansi`

Move some compile flags from the kernel makefile to bsd.kern.mk so that kernel modules are built with the right flags. Suggested by: Andrew Gallatin <gallatin@cs.duke.edu> 1998-12-17 22:36:21 +00:00			`#`
