Configuring Compiler Options

Configure the C Compiler Options in the Project — Options for Target — C dialog. The steps for configuring these options are:

  1. Enable Compile Thumb Code directs the compiler to generate ARM Thumb instruction set code for this project.
  2. Enable Support Calls between ARM and Thumb Instruction Set allows you to intermix Thumb and native ARM code within the same project.
  3. Enable APCS (ARM Procedure Call Standard) creates an application with standard parameter passing conventions.

For more options information, refer to the µVision User's Guide Options Settings chapter.
