# This file is processed when the IAR compiler is used for a C or C++ file
# Documentation can be downloaded here: http://www.iar.com/website1/1.0.1.0/675/1/
# The initial feature request is here: https://gitlab.kitware.com/cmake/cmake/-/issues/10176
# It also contains additional links and information.
# See USER GUIDES -> C/C++ Development Guide and ReleaseNotes for EWARM:
# version 6.30.8: http://supp.iar.com/FilesPublic/UPDINFO/006607/arm/doc/infocenter/index.ENU.html
# version 7.60.1: http://supp.iar.com/FilesPublic/UPDINFO/011006/arm/doc/infocenter/index.ENU.html
# version 8.10.1: http://netstorage.iar.com/SuppDB/Public/UPDINFO/011854/arm/doc/infocenter/index.ENU.html
# The IAR internal compiler platform generations (Predefined symbol __IAR_SYSTEMS_ICC__):
# 9 and higher means C11 and C++14 as language default (EWARM v8.x, EWRX v4.x and higher)
# 8 means C99 and C++03 as language default (EWARM v6.x, v7.x. EWRX v2.x, 3.x)
# 7 and lower means C89 and EC++ as language default. (EWARM v5.x and lower)
# C/C++ Standard versions
#
# IAR typically only supports one C and C++ Standard version,
# the exception is C89 which is always supported and can be selected
# if its not the default
#
# C++ is trickier, there were historically 3 switches,
# and some IAR versions support multiple of those.
# they are --eec++, --ec++ and --c++ and where used to
# enable various language features like exceptions
#
# recent versions only have --c++ for full support
# but can choose to disable features with further arguments
#
# C/C++ Standard compliance
#
# IAR has 3 modes: default, strict and extended
# the extended mode is needed for popular libraries like CMSIS
#
# "Silent" Operation
#
# this really is different to most programs I know.
# nothing meaningful from the operation is lost, just some redundant
# code and data size printouts (that can be inspected with common tools).
# This module is shared by multiple languages; use include blocker.
