Warning with Processor expert with -wall option

pgo — Tue, 13 Jan 2015 13:26:10 GMT

Hi,

I usually encourage students to compile their projects with the -wall option to catch a lot of 'newbie' errors.

While this may generate some noise it also helps catch some common errors.

Unfortunately when using PE it generates a lot of noise. While I have no reason to believe these are actual errors it would be better if there wasn't so much clutter.

Can I ask you to consider auditing your software for common items that trigger these warning? You never know it might actually find some bugs.

An example of code that produces a warning (from startup.c):

../Project_Settings/Startup_Code/startup.c:85:62: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
   else if( !(src & mask_short) && !(dst & mask_short) && len >= size_short)

bye

My apologies Marek,

The option that was active was -Wextra for extra warning.

Thank you for looking into this.
