Compiler/TCI6638K2K: Order of Section Splitting

Florian Oefelein

Part Number: TCI6638K2K

Tool/software: TI C/C++ Compiler

Hi,

we noticed that in case of section splitting the order of the input sections is sorted (SPRAA46A chapter 3.5). Is there a way to disable or bypass this ordering?

We'are generating a weighted call graph and are using the TI TMS320C6x Cache Layout Tool (clt6x) to generated a ordered list of functions. If we split the content between different memory sections the order is lost which ends in a performance degradation.

We use the following syntax:

OrderedCode
{
libX<ObjY.obj>(.text:function_1)
libX<ObjY.obj>(.text:function_2)
...
libX<ObjY.obj>(.text:function_n)
} >> SECTION1 | SECTION2

Any help would be welcome.

Best Regards,

Florian.

Hi George,
thank you for the fast reply. Do you have any other proposal to place functions in the right order over multiple sections without a manual split?
Best regards,
Florian.

Unfortunately, a manual split is the only way to do it. Just to be sure, I have a message in with the linker experts. However, since they are out, I don't expect any reply until next week.

Thanks and regards,

The experts confirmed a manual split is the only way to solve the problem. Sorry!
