I am originally using the default Cypress provided ARM GCC compiler for a PRoC project. In the compiler command line option, there is a customer flags: -std=c11
I believe it means it request the compiler to use C11 standard.
As my code size grow I need to use the Keil MDK compiler. I have installed the MDK and set the project to use it. However I want to set the same standard for the compiler, that is C11. How can I do that?
You should find that switch in the Keil MDK documentation.
