ULP how to disable diagnostics messages on a line by line basis

Dirk Osswald

Hello,

I like the diagnostics messages generated e.g. by the ULP - but not all the time. So is there a way to selectively disable diagnostics messages for a specific code line? Like e.g. by putting a special comment on the code line?

Background:

The diagnostics messages are often usefull and should be taken into account. But sometimes they are just wrong or not appropriate for the specific line of code. Instead of disabling the concerned message category alltogether on file or even project level, it would be helpfull to disable the diagnostics just for this one specific line of code.

Other diagnostics systems e.g. eclipse/pydev for Python provide such a mechanism. There the disabling works by putting a "# @CATEGORY" comment on the line. This 'disable-comment' can even be added via the CTRL-1 suggestion mechanism...

Thanks in advance for any comment.

This can be done using the diagnostic message pragmas, which are documented in the MSP430 Compiler User's Guide (section 5.11.8).

For example:

#pragma diag_suppress 1530
int a = (b % 8);
#pragma diag_default 1530

The first pragma disables the message "#1530-D (ULP 5.1) Detected modulo operation(s). Recommend moving them to RAM during run time or not using as these are processing/power intensive". The second pragma restores the default warning behaviour for this ULP diagnostic.

Thanks for the quick reply!

The syntax for achieving my goal is a little more verbose than I'd wish, - but hey it works!
