.Sh NAME
.Nm cpuflags
.Nd determine compiler flags to best target current CPU
.Sh SYNOPSIS
.Nm
.Op cc_pathname
.Sh DESCRIPTION
.Nm
determines the current CPU type and gcc version, then outputs appropriate
compiler options to best target code for that CPU.
If no options exist to target the current CPU then nothing is output.
.Pp
In the event of the CPU not being recognised, a warning is sent to stderr.
.Pp
If
.Pa cc_pathname
is not specified it defaults to the first
.Pa cc
found in the path.
.Sh ENVIRONMENT
The BSD makefile fragment
.Pa @PREFIX@/share/mk/cpuflags.mk
will set the following
.Xr make 1
variables, plus add CPU_FLAGS and CPU_DIR to .MAKEFLAGS for sub-makes.
.Pp
.Bl -tag -width CPU_FLAGS -compact
.It CPU_FLAGS
The output of cpuflags
.It CPU_DIR
CPU_FLAGS with spaces stripped (eg: for use in PACKAGES)
.It CFLAGS
Has CPU_FLAGS appended
.It CXXFLAGS
Has CPU_FLAGS appended
.El
.Sh FILES
.Bl -tag -width @PREFIX@/share/mk/optimize_gcc.mk -compact
.It @PREFIX@/share/mk/cpuflags.mk
Set appropriate compiler flags based on the output from
.Nm .
Suitable for inclusion in /etc/mk.conf
.It @PREFIX@/share/mk/optimize_gcc.mk
Attempt to set additional -mXXX gcc flags based on gcc version and packages
being compiled.
Note: This is experimental and not supported.
.El
.Sh EXAMPLES
.Nm
can be used to set default flags for building entries from pkgsrc
and recompiling the
.Nx
kernel or userland by adding the following to
.Pa /etc/mk.conf :
.Bd -literal -offset indent
.sinclude "@PREFIX@/share/mk/cpuflags.mk"
.Ed
.Pp
To experiment with optimisations that can break generated code there is
optimize_gcc.mk.
This is unsupported, but for full effect add the following to
.Pa /etc/mk.conf :
.Bd -literal -offset indent
.sinclude "@PREFIX@/share/mk/cpuflags.mk"
.sinclude "@PREFIX@/share/mk/optimize_gcc.mk"
.Ed
.Pp
On all except low memory machines compilation can be speeded up by adding the
following to /etc/mk.conf.
(Note this will not affect the binaries produced)
.Bd -literal -offset indent
COPTS?= -pipe ${DEFCOPTS}
CFLAGS+=-pipe
.Ed
.Sh BUGS
.Nm
still needs to learn about more CPU types - updates welcomed
to
.Aq abs@NetBSD.org .
Also the Makefile fragments and examples are BSD make
specific - gmake examples welcomed.
.Pp
Currently
.Nm
is also gcc specific.
.Sh NOTES
.Nm
is based on input from many sources.
I would like to thank them all, in particular Yakovetsky Vladimir.
