#    -mapcs32		Generate code for a processor running with a 32-bit program
#					counter, and conforming to the function calling standards for
#					the APCS 32-bit option.
#    -mcpu      	specifies the name of the target ARM processor.
#    -msoft-float   Generate output containing library calls for floating point.
#    -c 			Compile only
#    -0 			Optimize
#    -ffloat-store	Do not store floating point variables in registers
#					and inhabit other options that might change whether
#					floating point value is taken from register or
#					memory.
#    -g3			The compiler debugging option, followed by the level.
#					Level 3 included extra information.
#    -Wall			Issue warnings.
#    -r 			Elimates the use of built-in implicit rules.
#    -save-temps	Do not delete intermediate files
