nity gritty for building software on Cortex-M


	# Getting Keil (armcc) to build gcc/iar compatible libraries
	--library_interface=aeabi_clib

	# Soft vs Hard FP
	Soft versus hard FP is about function calling conventions, and binaries compiled with softfp will simply crash when loaded into a hardfp system.

	/hardfp, /softfp
	Requests hardware or software floating-point linkage. This enables the procedure call standard to be specified separately from the version of the floating-point hardware available through the --fpu option. It is still possible to specify the procedure call standard by using the --fpu option, but ARM recommends that you use --apcs instead.
