c253d72f0a Bump the -mev56 to -mev6. Otherwise, when you compile with gcc using
ev6 or pca56 etc this downgrades the cpu specification passed to gas.
As a result, gas will fail when gcc generates media instructions (in
uipc_usrreq.c).  This only affects what gas will accept, not what gcc
generates or what our *.s file contain.

64fc62d407 Turned format checking back on. It was left turned off for too long after
the gcc lossage that caused it to be turned off was fixed.

Tested with:	i386/{GENERIC,LINT,...}, alpha/GENERIC

e09d00a880 For now, make the .ifdef GCC3 case default. We should change -Wno-format
back to -fformat-extensions (or whatever) when we have the functionality.
We are gaining warnings again that should be fixed but the are being hidden
by NO_WERROR and all the -Wformat noise.

856f29cf94 Use -ffreestanding for kernel bits unconditionally. 2002-05-04 20:07:33 +00:00

ea8f3ee347 This will have to be revised, but allow putting 'makeoptions GCC3=true'
in a kernel config file.  This should minimize the tearing-out-hair process
while updating the kernel for gcc-3 compliance.

b453864c6a Fix the grammar in my previous commit "lose" -> "loss".
I should have done it that way in the first place.

54d477a4f1 Make "-mpreferred-stack-boundary=2" the default on the i386.
This reduces the size of the kernel and modules when compiled with GCC 2.95.

9a6c0bd6c9 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".

65be2aace6 Move some compile flags from the kernel makefile to bsd.kern.mk so that
kernel modules are built with the right flags.

405b59bcb5 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.

6e47de28bb Added -Wuninitialized to CWARNFLAGS. Warnings about uninitialialized
variables were lost when we removed -W, and 23 new ones including at
least one serious one have crept in for LINT.

Restored -Winline to CFLAGS.  This gives only 3 old warnings and 1 new
for LINT.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

a400403a8c Turned off -W and -Winline so that the warnings that should be fixed for
2.2 are more obvious.  -Winline is unimportant, but -W gives thousands
of warnings for comparisions.  Turning off -W also loses warnings for:
- auto variables clobbered by longjmp.  Not much of a problem in the kernel.
- functions returning without a value.  I don't like losing this.
- an expression statement or the left side of a comma operand contains no
  side effects.  Turning this off also stops warnings for the low quality
  debugging macros in gsc.c and lpt.c.

Should be in 2.2.

272937b07f Oops, this wasn't supposed to have -Wcast-qual yet.
Also disabled -Wunused.  It caused too many warnings even for me.
The sign mismatch warnings should be fixed first.  They are more
important and harder to disable (they are controlled by -W, which
controls too many things).
