No warning for reduplicated section in cmd file for TI C6x 7.x.x linker

I am using TI C6x 7.x.x compiler/linker to do my job

I have put my data section myGlobalData in two different memory places by mistake in my cmd file.

I have seen no warning or remark for my mistake during building my executalbe file.

Does TI linker has warning for such kind of mistake?

As far as I know, there isn't a way to enable a warning for this. The linker will allocate the section based on the first directive it encounters in the linker command file and ignore the second.

Hi Aarti,

Is that possible for TI to add this kind of warning into the linker?

It's a design issue; as designed, it is not an error for more than one SECTIONS pattern to match a particular input section. Therefore, a warning is not appropriate.

It could be argued that if two patterns are exactly the same, there is ambiguity, and for this case we should generate a warning. However, if there are existing working projects which have this sort of thing going on (perhaps because they use several linker command files from different authors), those projects would suddenly start getting warnings.

Hi Archaeologist,

Sorry, I don't get your point clearly.

"It could be argued that if two patterns are exactly the same, there is ambiguity, and for this case we should generate a warning."

is that mean you should but you didn't implement it in linker?

I think my case is the same as your described. But we didn't get a warning.

I'm saying that it is not clear that there should be a warning.
