TMS320F28379D: Can compiler generate instructions that read anything from .text section?

One such case is the .TI.ramfunc/Cla1Prog/.const_cla sections. These are loaded to Flash and copied to RAM at run time. This copy involves a read from Flash

Hi Veena,

Thank you for reminding me about ram functions and related data.

How is with regular code in .text? Can the compiler generate some constant, put it inside a code and use some read during execusion?

I remember the code for ARM processors, where compilers often place some address behind the function and used [pc+relative_offset] addressing to load it into register.

It was something like this:

    ld r1,[pc+relative_offset]

[...]

here points pc+relative_offset:   data 0x12345678

The code that I am securing is large, I cannot browse it all, so I am looking for some general confirmation that setting EXEONLY for .text wil be not harmfull.

I don't think so.  I expect to be able to provide confirmation by tomorrow.

Thanks and regards,
