 -1 Didn't Search First		 #89756 - Optimized Code for Keil C Compiler
I am using Keil's student or demo version of their C compiler for the 8051 and find it to be very inefficient. I have written a short kernel program in both assembly language as well as C and find my C program is four times longer than my assembly language program. I am a much better assembly language programmer than C so assume I must be using some ineffective instructions. Can anyone give me some general suggestions on how to obtimize my code. There must be some C instructions I should stay away from. With a 2K limit on the object code I really need some help. Thanks
