# This template file can be used as a starting point for implementing support
# for additional tools for reading and/or conversion of elf files.
#
# Although GNU bintools is used as name, then the template can be used to
# support other tools.
#
# Overview of bintools used commands:
# - memusage : Tool for reporting target memory usage
# (if linker support memusage reporting leave this property empty)
# - disassembly : Tool for disassemble the target
# - elfconvert : Tool for converting from elf into another format.
# - readelf : Tool for elf file processing
# - strip : Tool for symbol stripping
# - symbols : Tool for listing symbols in a binary
#
# Each tool will have the following minimum properties:
# - <tool>_command : Name of executable to call
# - <tool>_flag : Flags that must always be used with this command
# - <tool>_flag_infile : Flag to use when specifying the file to process
# - <tool>_flag_outfile : Flag to use to specify the result of the processing.
#
# each tool might require more flags depending on its use, as example:
# - elfconvert_flag_section_remove : Flag to use when specifying sections to remove
# - readelf_flags_headers : Flag to use to specify headers should be displayed
#
# If a given tool / flag / feature is not supported, then keep the property empty.
# As bintools_template.cmake default has empty flags, then it is sufficient to
# only set those flags that a given set of tools support.
#
# Commands will default echo a message if called, but no command has been defined.
# This is done, so that unexpected calls to non-implemented command can be easily detected.
# To disable the message, simply silence the command with:
# set_property(TARGET bintools PROPERTY <command>_command ${CMAKE_COMMAND} -E echo "")
#
# The bintools properties are made generic so that implementing support for an
# additional native tool should be as easy as possible.
# However, there might be tools and/or use cases where the current property
# scheme does not cover the exact needs. For those use-cases it is possible
# to implement the call to a native tool inside a CMake script.
# For example, to call a custom script for elfconvert command, one can specify:
# set_property(TARGET bintools PROPERTY elfconvert_command ${CMAKE_COMMAND})
# set_property(TARGET bintools PROPERTY elfconvert_flag "")
# set_property(TARGET bintools PROPERTY elfconvert_flag_final -P custom_elfconvert.cmake)
# set_property(TARGET bintools PROPERTY elfconvert_flag_strip_all "-DSTRIP_ALL=True")
# set_property(TARGET bintools PROPERTY elfconvert_flag_infile "-DINFILE=")
# set_property(TARGET bintools PROPERTY elfconvert_flag_outfile "-DOUT_FILE=")
#
#
# bintools property overview of all commands:
#
# Command:
# - memusage : Name of command to execute
# Note: For gcc compilers this command is not used,
# instead a linker flag is used for this)
# memusage_flag : Flags that must always be applied when calling memusage command
# memusage_flag_final : Flags that must always be applied last at the memusage command
# memusage_flag_infile: Flag for specifying the input file
# memusage_byproducts : Byproducts (files) generated when calling memusage
#
#
# - elfconvert : Name of command for elf file conversion.
# For GNU binary utilities this is objcopy
# elfconvert_formats : Formats supported by this command.
# elfconvert_flag : Flags that must always be applied when calling elfconvert command
# elfconvert_flag_final : Flags that must always be applied last at the elfconvert command
# elfconvert_flag_strip_all : Flag that is used for stripping all symbols when converting
# elfconvert_flag_strip_debug : Flag that is used to strip debug symbols when converting
# elfconvert_flag_intarget : Flag for specifying target used for infile
# elfconvert_flag_outtarget : Flag for specifying target to use for converted file.
# Target value must be one of those listed described by: elfconvert_formats
# elfconvert_flag_section_remove: Flag for specifying that following section must be removed
# elfconvert_flag_section_only : Flag for specifying that only the following section should be kept
# elfconvert_flag_section_rename: Flag for specifying that following section must be renamed
# elfconvert_flag_gapfill : Flag for specifying the value to fill in gaps between sections
# elfconvert_flag_srec_len : Flag for specifying maximum length of Srecord values
# elfconvert_flag_infile : Flag for specifying the input file
# elfconvert_flag_outfile : Flag for specifying the output file
# For tools that prints to standard out, this should be ">" to indicate redirection
#
#
# - disassembly : Name of command for disassembly of files
# For GNU binary utilities this is objdump
# disassembly_flag : Flags that must always be applied when calling disassembly command
# disassembly_flag_final : Flags that must always be applied last at the disassembly command
# disassembly_flag_inline_source : Flag to use to display source code mixed with disassembly
# disassembly_flag_all : Flag to use for disassemble everything, including zeroes
# disassembly_flag_infile : Flag for specifying the input file
# disassembly_flag_outfile : Flag for specifying the output file
# For tools that prints to standard out, this should be ">" to indicate redirection
#
#
# - readelf : Name of command for reading elf files.
# For GNU binary utilities this is readelf
# readelf_flag : Flags that must always be applied when calling readelf command

# readelf_flag_headers : Flag to use for specifying ELF headers should be read
# readelf_flag_infile : Flag for specifying the input file
# readelf_flag_outfile : Flag for specifying the output file
# For tools that prints to standard out, this should be ">" to indicate redirection
#
#
