Dual-State Interworking
It can be seen that the "Code State Mode" is set to 32-BIS Mode (--code_state=32) and the –mt built
option is not chosen. This means that the compiler will make sure that the generated assembly code will
switch to ARM mode when executing this specific part of the code. And the ARM mode instruction set will
be used to perform this section of the code.
For additional information, please refer to the following reference material:
• ARM Optimizing C/C++ Compiler v5.2 User's Guide (SPNU151)
• • ARM Assembly Language Tools v5.2 (CCS 6) (SPNU118)
