3# make.conf(5) manual page, if necessary, which is located in
4# src/share/man/man5/make.conf.5.
5#
6# /etc/make.conf, if present, will be read by make (see
7# /usr/share/mk/sys.mk).  It allows you to override macro definitions
8# to make without changing your source tree, or anything the source
9# tree installs.
10#
11# This file must be in valid Makefile syntax.
12#
13# There are additional things you can put into /etc/make.conf.
14# You have to find those in the Makefiles and documentation of
15# the source tree.
16#
17# Note, that you should not set MAKEOBJDIRPREFIX or MAKEOBJDIR
18# from make.conf (or as command line variables to make).
19# Both variables are environment variables for make and must be used as:
20#
21# env MAKEOBJDIRPREFIX=/big/directory make
22#
23#
24# The CPUTYPE variable controls which processor should be targeted for
25# generated code.  This controls processor-specific optimizations in
26# certain code (currently only OpenSSL) as well as modifying the value
27# of CFLAGS to contain the appropriate optimization directive to cc.
28# The automatic setting of CFLAGS may be overridden using the
29# NO_CPU_CFLAGS variable below.
30# Currently the following CPU types are recognized:
31#   Intel x86 architecture:
32#       (AMD CPUs)	znver4, znver3, znver2, znver1, bdver4, bdver3, bdver2,
33#			bdver1, btver2, btver1, amdfam10, opteron-sse3,
34#			athlon64-sse3, k8-sse3, opteron, athlon64, athlon-fx,
35#			k8, athlon-mp, athlon-xp, athlon-4, athlon-tbird,
36#			athlon, k7, geode, k6-3, k6-2, k6
37#       (Intel CPUs)	alderlake, sapphirerapids, tigerlake, cooperlake,
38#			cascadelake, tremont, goldmont-plus, icelake-server,
39#			icelake-client, cannonlake, knm, skylake-avx512, knl,
40#			goldmont, skylake, broadwell, haswell, ivybridge,
41#			sandybridge, westmere, nehalem, silvermont, bonnell,
42#			core2, core, nocona, pentium4m, pentium4, prescott,
43#			pentium3m, pentium3, pentium-m, pentium2, pentiumpro,
44#			pentium-mmx, pentium, i486
45#       (VIA CPUs)	c7, c3-2, c3
46#   ARM architecture:	armv7, armv7-a, armv7ve, generic-armv7-a, cortex-a5,
47#			cortex-a7, cortex-a8, cortex-a9, cortex-a12,
48#			cortex-a15, cortex-a17
49#   ARM64 architecture:	cortex-a53, cortex-a57, cortex-a72,
50#				exynos-m1

55#NO_CPU_CFLAGS=		# Don't add -march=<cpu> to CFLAGS automatically
56#
57# CFLAGS controls the compiler settings used when compiling C code.
58# Note that optimization settings other than -O and -O2 are not recommended
59# or supported for compiling the world or the kernel - please revert any
60# nonstandard optimization settings
61# before submitting bug reports without patches to the developers.
62#
63# CFLAGS.arch provides a mechanism for applying CFLAGS only when building
64# the given architecture.  This is useful primarily on a system used for
65# cross-building, when you have a set of flags to apply to the TARGET_ARCH
66# being cross-built but don't want those settings applied to building the
67# cross-tools or other components that run on the build host machine.
68#
69# CXXFLAGS controls the compiler settings used when compiling C++ code.
70# Note that CXXFLAGS is initially set to the value of CFLAGS.  If you wish
71# to add to CXXFLAGS value, "+=" must be used rather than "=".  Using "="
72# alone will remove the often needed contents of CFLAGS from CXXFLAGS.
73#
74# Additional compiler flags can be specified that extend or override
75# default ones. However, neither the base system nor ports are guaranteed
76# to build and function without problems with non-default settings.
77#
78# CFLAGS+=	-msse3
79# CXXFLAGS+=	-msse3
80# CFLAGS.armv7+= -mfloat-abi=softfp
81#
82# MAKE_SHELL controls the shell used internally by make(1) to process the
83# command scripts in makefiles.  Three shells are supported, sh, ksh, and
84# csh.  Using sh is most common, and advised.  Using ksh *may* work, but is
85# not guaranteed to.  Using csh is absurd.  The default is to use sh.
86#
87#MAKE_SHELL?=sh
88#
89# BDECFLAGS are a set of gcc warning settings that Bruce Evans has suggested
90# for use in developing FreeBSD and testing changes.  They can be used by
91# putting "CFLAGS+=${BDECFLAGS}" in /etc/make.conf.  -Wconversion is not
92# included here due to compiler bugs, e.g., mkdir()'s mode_t argument.
93#
94#BDECFLAGS=	-W -Wall -ansi -pedantic -Wbad-function-cast -Wcast-align \
95#		-Wcast-qual -Wchar-subscripts -Winline \
96#		-Wmissing-prototypes -Wnested-externs -Wpointer-arith \
97#		-Wredundant-decls -Wshadow -Wstrict-prototypes -Wwrite-strings
98#
99# To compile just the kernel with special optimizations, you should use
100# this instead of CFLAGS (which is not applicable to kernel builds anyway).
101# There is very little to gain by using higher optimization levels, and doing
102# so can cause problems.
