Hi all. I have two questions.
In the startup.c file, the stack pointer declaration _SP_INIT as char, when I add LTO option with linker, there's a warning: "warning: type of '__SP_INIT' does not match original declaration", I want to disable it, and not know how?
And the second one is that, when compiled with O2, I found a locale variable is optimized out which used in asm instructions. So, my question is that, how to avoid this in ALL of source files generated by Processor Export?
