Intel C/C++ compiler (lang/icc) to build the kernel.
The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but
doesn't abort. They also produce CPU specific code (new instructions
of the CPU, not only CPU specific scheduling), so if you get coredumps
with signal 4 (SIGILL, illegal instruction) you've used the wrong
CPUTYPE.
Incarnations of this patch survive gcc compiles and my make universe.
I use it on my desktop.
To use it update share/mk, add
/usr/local/intel/compiler70/ia32/bin (icc v7, works)
or
/usr/local/intel_cc_80/bin (icc v8, doesn't work)
to your PATH, make sure you have a new kernel compile directory
(e.g. MYKERNEL_icc) and run
CFLAGS="-O2 -ip" CC=icc make depend
CFLAGS="-O2 -ip" CC=icc make
in it.
Don't compile with -ipo, the build infrastructure uses ld directly to
link the kernel and the modules, but -ipo needs the link step to be
performed with Intel's linker.
Problems with icc v8:
- panic: npx0 cannot be emulated on an SMP system
- UP: first start of /bin/sh results in a FP exception

An attempt to work around the problems caused by using
ld(1) for stripping was to pass LDFLAGS to the ld(1)
command, but this was not right either as ${LDFLAGS}
should, by design, be used with cc(1) and not ld(1).
One of the proposed solutions was to use the objcopy(1)

use strip(1), but Bruce Evans suggested not stripping
any symbols at all. This works by leaving the grunt

FreeBSD. This method attempts to centralize all the necessary hacks
or work arounds in one of two places in the tree (src/Makefile.inc1
and src/tools/build). We build a small compatibility library
(libbuild.a) as well as selectively installing necessary include
files. We then include this directory when building host binaries.
This removes all the past release compatibilty hacks from various

will work with those that want to support more, although I anticipate
it will just work.

Fix the "@gprel relocation against dynamic symbol xxx" linker error.
Variables defined in the link unit and small enough to be put in the
short data section will have a gp-relative access sequence (using the
@gprel relocation). It is invalid to have @gprel relocations in shared
libraries, because they are to be resolved by the static linker and
not the dynamic linker. The -fpic option will cause @ltoff relocations
for @gprel relocations, but the side-effects are untested (if any).
Instead, disable/eliminate the short data section to achieve the same.
In "nroff" mode, italic font renders as an underlined text, which

So turn off the color support for now (when generating catpages),
until we figure out what do we do with this new feature. I have
a patch for grotty(1) that tells it to use the "reverse video"
attribute to render the italic font. Once this is accepted, we
can turn color support back on (if there won't be any objections

- Treat an empty CPUTYPE the same as an undefined CPUTYPE.

to make it call `install' in the bsd.subdir.mk-driven makefiles
too. (share/examples/Makefile,v 1.29 changed the bsd.prog.mk
to bsd.subdir.mk and many stuff was lost during "make release".
I then merged this change in rev. 1.28.2.2 to work around the
namespace pollution (FILES) in this makefile.)
There was an added complexity here. Both the `distribute' and
`install' targets are recursive (they propagate to SUBDIRs).
So `distribute' first calls `install' in the ${.CURDIR}, then
calls `distribute' in each SUBDIR, etc. The problem is that
`install' (being also recursive) causes the stuff from SUBDIR
to be installed twice, first time thru `install' in ${.CURDIR}
triggered by `distribute', second time by `distribute' run in
the SUBDIR. This problem is not new, but it became apparent
only after I moved the `distribute' target from bsd.obj.mk to
bsd.subdir.mk. My first attempt testing the fix failed due to
this, because the whole world was distributed twice, causing
all the imaginable mess (kerberos5 stuff was installed into both
"base" and "krb5" dists, there was /sbin/init.bak, etc.)
I say the problem is not new because bsd.prog.mk and bsd.lib.mk
makefiles with SUBDIR (even without this fix) had this problem
for years. Try e.g. running ``make distribute DISTDIR=/foo''
from usr.bin/bzip2 or from lib/libcom_err (without the fix) and
watch the output.
So the solution was to make `install' behave non-recursive when
executed by `distribute'. My first attempt in passing SUBDIR=
to the `install' in the `distribute' body failed because of the
way how src/Makefile and src/Makefile.inc1 communicate with each
other. SUBDIR='s assignment precedence on the "make install
SUBDIR=" command line is lowered after src/Makefile wrapper calls
"make ... -f ${.CURDIR}/Makefile.inc1 install" because SUBDIR=
is moved into environment, and Makefile.inc1's assignments now
take higher precedence. This may be fixed someday when we merge
Makefile with Makefile.inc1. For now, this is implemented as a
NO_SUBDIR knob.
