1# $FreeBSD$ 2 3# Part of a unified Makefile for building kernels. This part contains all 4# of the definitions that need to be before %BEFORE_DEPEND. 5 6# Allow user to configure things that only effect src tree builds. 7# Note: This is duplicated from src.sys.mk to ensure that we include 8# /etc/src.conf when building the kernel. Kernels can be built without 9# the rest of /usr/src, but they still always process SRCCONF even though 10# the normal mechanisms to prevent that (compiling out of tree) won't 11# work. To ensure they do work, we have to duplicate thee few lines here. 12SRCCONF?= /etc/src.conf 13.if (exists(${SRCCONF}) || ${SRCCONF} != "/etc/src.conf") && !target(_srcconf_included_) 14.include "${SRCCONF}" 15_srcconf_included_: 16.endif 17 18.include <bsd.own.mk> 19.include <bsd.compiler.mk> 20.include "kern.opts.mk" 21 22# Can be overridden by makeoptions or /etc/make.conf 23KERNEL_KO?= kernel 24KERNEL?= kernel 25KODIR?= /boot/${KERNEL} 26LDSCRIPT_NAME?= ldscript.$M 27LDSCRIPT?= $S/conf/${LDSCRIPT_NAME} 28 29M= ${MACHINE} 30 31AWK?= awk 32CP?= cp 33LINT?= lint 34NM?= nm 35OBJCOPY?= objcopy 36SIZE?= size 37 38.if defined(DEBUG) 39_MINUS_O= -O 40CTFFLAGS+= -g 41.else 42.if ${MACHINE_CPUARCH} == "powerpc" 43_MINUS_O= -O # gcc miscompiles some code at -O2 44.else 45_MINUS_O= -O2 46.endif 47.endif 48.if ${MACHINE_CPUARCH} == "amd64" 49.if ${COMPILER_TYPE} == "clang" 50COPTFLAGS?=-O2 -pipe 51.else 52COPTFLAGS?=-O2 -frename-registers -pipe 53.endif 54.else 55COPTFLAGS?=${_MINUS_O} -pipe 56.endif 57.if !empty(COPTFLAGS:M-O[23s]) && empty(COPTFLAGS:M-fno-strict-aliasing) 58COPTFLAGS+= -fno-strict-aliasing 59.endif 60.if !defined(NO_CPU_COPTFLAGS) 61COPTFLAGS+= ${_CPUCFLAGS} 62.endif 63NOSTDINC= -nostdinc 64 65INCLUDES= ${NOSTDINC} ${INCLMAGIC} -I. -I$S 66 67.if make(depend) || make(kernel-depend) 68 69# This hack lets us use the ipfilter code without spamming a new 70# include path into contrib'ed source files. 71INCLUDES+= -I$S/contrib/ipfilter 72 73# ... and the same for ath 74INCLUDES+= -I$S/dev/ath -I$S/dev/ath/ath_hal -I$S/contrib/dev/ath/ath_hal 75 76# ... and the same for the NgATM stuff 77INCLUDES+= -I$S/contrib/ngatm 78 79# ... and the same for vchiq 80INCLUDES+= -I$S/contrib/vchiq 81 82# ... and the same for twa 83INCLUDES+= -I$S/dev/twa 84 85# ... and the same for cxgb and cxgbe 86INCLUDES+= -I$S/dev/cxgb -I$S/dev/cxgbe 87 88.endif 89 90CFLAGS= ${COPTFLAGS} ${DEBUG} 91CFLAGS+= ${INCLUDES} -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h 92CFLAGS_PARAM_INLINE_UNIT_GROWTH?=100 93CFLAGS_PARAM_LARGE_FUNCTION_GROWTH?=1000 94.if ${MACHINE_CPUARCH} == "mips" 95CFLAGS_ARCH_PARAMS?=--param max-inline-insns-single=1000 96.endif 97CFLAGS.gcc+= -fno-common -fms-extensions -finline-limit=${INLINE_LIMIT} 98CFLAGS.gcc+= --param inline-unit-growth=${CFLAGS_PARAM_INLINE_UNIT_GROWTH} 99CFLAGS.gcc+= --param large-function-growth=${CFLAGS_PARAM_LARGE_FUNCTION_GROWTH} 100.if defined(CFLAGS_ARCH_PARAMS) 101CFLAGS.gcc+=${CFLAGS_ARCH_PARAMS} 102.endif 103WERROR?= -Werror 104 105# XXX LOCORE means "don't declare C stuff" not "for locore.s". 106ASM_CFLAGS= -x assembler-with-cpp -DLOCORE ${CFLAGS} ${ASM_CFLAGS.${.IMPSRC:T}} 107 108.if defined(PROFLEVEL) && ${PROFLEVEL} >= 1 109CFLAGS+= -DGPROF 110CFLAGS.gcc+= -falign-functions=16 111.if ${PROFLEVEL} >= 2 112CFLAGS+= -DGPROF4 -DGUPROF 113PROF= -pg 114.if ${COMPILER_TYPE} == "gcc" 115PROF+= -mprofiler-epilogue 116.endif 117.else 118PROF= -pg 119.endif 120.endif 121DEFINED_PROF= ${PROF} 122 123# Put configuration-specific C flags last (except for ${PROF}) so that they 124# can override the others. 125CFLAGS+= ${CONF_CFLAGS} 126 127# Optional linting.
