#                                BSP MAKEFILE
#
# This makefile was automatically generated by the nios2-bsp-generate-files
# command. Its purpose is to build a custom Board Support Package (BSP)
# targeting a specific Nios II processor in an SOPC Builder-based design.
#
# To create an application or library Makefile which uses this BSP, try the
# nios2-app-generate-makefile or nios2-lib-generate-makefile commands.

# If COMSPEC is defined, Make is launched from Windows through
# Cygwin.  This adjust-path macro will call 'cygpath -u' on all
# paths to ensure they are readable by Make.
#
# If COMSPEC is not defined, Make is launched from *nix, and no adjustment
# is necessary

#                              MANAGED CONTENT
#
# All content between the lines "START MANAGED" and "END MANAGED" below is
# generated based on variables in the BSP settings file when the
# nios2-bsp-generate-files command is invoked. If you wish to persist any
# information pertaining to the build process, it is recomended that you
# utilize the BSP settings mechanism to do so.
#
# Note that most variable assignments in this section have a corresponding BSP
# setting that can be changed by using the nios2-bsp-create-settings or  
# nios2-bsp-update-settings command before nios2-bsp-generate-files; if you 
# want any variable set to a specific value when this Makefile is re-generated 
# (to prevent hand-edits from being over-written), use the BSP settings 
# facilities above.
#------------------------------------------------------------------------------

#START MANAGED

# The following TYPE comment allows tools to identify the 'type' of target this 
# makefile is associated with. 
# TYPE: BSP_PRIVATE_MAKEFILE

# This following VERSION comment indicates the version of the tool used to 
# generate this makefile. A makefile variable is provided for VERSION as well. 
# ACDS_VERSION: 13.0sp1
ACDS_VERSION := 13.0sp1

# This following BUILD_NUMBER comment indicates the build number of the tool 
# used to generate this makefile. 
# BUILD_NUMBER: 232

#-------------------------------------------------------------------------------
#                             TOOL & COMMAND DEFINITIONS
# 
# The base command for each build operation are expressed here. Additional
# switches may be expressed here. They will run for all instances of the 
# utility.
#-------------------------------------------------------------------------------

# Archiver command. Creates library files. 
AR = nios2-elf-ar

# Assembler command. Note that CC is used for .S files. 
AS = nios2-elf-gcc

# Custom flags only passed to the archiver. This content of this variable is 
# directly passed to the archiver rather than the more standard "ARFLAGS". The 
# reason for this is that GNU Make assumes some default content in ARFLAGS. 
# This setting defines the value of BSP_ARFLAGS in Makefile. 
BSP_ARFLAGS = -src

# Custom flags only passed to the assembler. This setting defines the value of 
# BSP_ASFLAGS in Makefile. 
BSP_ASFLAGS = -Wa,-gdwarf2

# C/C++ compiler debug level. '-g' provides the default set of debug symbols 
# typically required to debug a typical application. Omitting '-g' removes 
# debug symbols from the ELF. This setting defines the value of 
# BSP_CFLAGS_DEBUG in Makefile. 
BSP_CFLAGS_DEBUG = -g

# C/C++ compiler optimization level. "-O0" = no optimization,"-O2" = "normal" 
# optimization, etc. "-O0" is recommended for code that you want to debug since 
# compiler optimization can remove variables and produce non-sequential 
# execution of code while debugging. This setting defines the value of 
# BSP_CFLAGS_OPTIMIZATION in Makefile. 
BSP_CFLAGS_OPTIMIZATION = -O2

# C/C++ compiler warning level. "-Wall" is commonly used.This setting defines 
# the value of BSP_CFLAGS_WARNINGS in Makefile. 
BSP_CFLAGS_WARNINGS = -Wall

# C compiler command. 
CC = nios2-elf-gcc -xc

# C++ compiler command. 
CXX = nios2-elf-gcc -xc++

# Command used to remove files during 'clean' target. 
RM = rm -f


#-------------------------------------------------------------------------------
#                         BUILD PRE & POST PROCESS COMMANDS
# 
# The following variables are treated as shell commands in the rule
# definitions for each file-type associated with the BSP build, as well as
# commands run at the beginning and end of the entire BSP build operation.
# Pre-process commands are executed before the relevant command (for example,
# a command defined in the "CC_PRE_PROCESS" variable executes before the C
# compiler for building .c files), while post-process commands are executed
# immediately afterwards.
# 
# You can view each pre/post-process command in the "Build Rules: All &
# Clean", "Pattern Rules to Build Objects", and "Library Rules" sections of
# this Makefile.
#-------------------------------------------------------------------------------


#-------------------------------------------------------------------------------
#                     BSP SOURCE BUILD SETTINGS (FLAG GENERATION)
# 
# Software build settings such as compiler optimization, debug level, warning
# flags, etc., may be defined in the following variables. The variables below
# are concatenated together in the 'Flags' section of this Makefile to form
# final variables of flags passed to the build tools.
# 
# These settings are considered private to the BSP and apply to all library &
# driver files in it; they do NOT automatically propagate to, for example, the
# build settings for an application.
# # For additional detail and syntax requirements, please refer to GCC help
# (example: "nios2-elf-gcc --help --verbose").
# 
# Unless indicated otherwise, multiple entries in each variable should be
# space-separated.

#                            BSP SOURCE FILE LISTING
# 
# All source files that comprise the BSP are listed here, along with path 
# information to each file expressed relative to the BSP root. The precise 
# list and location of each file is derived from the driver, operating system, 
# or software package source file declarations.
#
# Following specification of the source files for each component, driver, etc.,
# each source file type (C, assembly, etc.) is concatenated together and used
# to construct a list of objects. Pattern rules to build each object are then
# used to build each file.

#
# In addition, public.mk contains include paths that various software,
# such as a device driver, may need for the C compiler. These paths are
# written to public.mk with respect to the BSP root. In public.mk, each
# path is prefixed with a special variable, $(ALT_LIBRARY_ROOT_DIR). The
# purpose of this variable is to allow an external Makefile to append on
# path information to precisely locate paths expressed in public.mk
# Since this is the BSP Makefile, we set ALT_LIBRARY_ROOT_DIR to point right
# here ("."), at the BSP root.

# Extended description: The list of objects is a sorted list (duplicates
# removed) of all possible objects, placed beneath the ./obj directory,
# including any path information stored in the "*_SRCS" variable. The
# "patsubst" commands are used to concatenate together multiple file suffix
# types for common files (i.e. c++ as .cxx, .cc, .cpp).
#
# File extensions are case-insensitive in build rules with the exception of
# assembly sources. Nios II assembly sources with the ".S" extension are first
# run through the C preprocessor. Sources with the ".s" extension are not.
