Creator 3.0 Major(?) Bug Report

user_1377889 Jan 4, 2014 6:29 AM

When trying to access a specified register in GCC the syntax is given clearly. Here an example:

volatile register uint32 R2 asm ("r2");

This line gets flagged by the code-checker stating that the label "r2" is ignored because R2 is an automatic variable.

Instead declaring

static volatile register uint32 R2 asm ("r2");

is accepted and no error displayed.

But when compiled, the first declaration is error-free and the register can be accessed from C without any problems, while the second declaration is flgges as an error.

I admit that this issue will only touch the "Cracks", but the truth is: I am one.

This is my day!!!

No text-mixing by the code editor when using pasted lines!

Nice catch Bob.

Wouldn't it be good if there was nice place to report bugs to cypress - not for support like 'My Cases' just to ley the dev teams know.

I have noticed that too. I actually thought I was doing something wrong.

Robyn, shall we consider to mail our bugs directly to you? You already have taken over sometimes and re-directed that information into the right channels. Only the frequent contributors will remember such an arrangement, so you will not bath in emails. The question is: who (you?) is going to make that job...

You can certainly email me any bugs you find (or feature improvements you'd like)! I do try to enter any bugs/challenges that I see on the forums for our dev team. You can email me at RBYN at cypress dot com anytime if you'd like to report things though.
