There's a knowledgebase article that was last reviewed on June 7, 2005 that says the CARM compiler does not support 64-bit unsigned integers. I'm using the ARMCC compiler (from the RealView MDK-ARM toolchain), and the following code
char s[100]; unsigned int x32; unsigned long int x64; sprintf(s,"sizeof(x32)=%u\r\n",sizeof(x32)); printf(s); sprintf(s,"sizeof(x64)=%u\r\n",sizeof(x64)); printf(s);
produces the following output
sizeof(x32)=4 sizeof(x64)=4
This leads me to believe that the ARMCC tools don't support 64-bit math either.
However, if that's so, why doesn't the above code create any errors or warnings when it's compiled?
Is there a way to get 64-bit unsigned integer support in these tools?
Okay... here's a simple suggestion...
Why not make the help files in PDF format? At least that way you'd have full-text-search for the whole doc, and... if you did want to print it out (in part, or in whole)... you could!
You can put all the hyper-linking stuff in PDF's too, if you wanted to.
I feel your pain about so many PDF doc's not having the annotation facility enabled! I miss the little paper clip annotations you could do in the old Windoze help files too.
But... I sure do love this forum. It's bailed me out on multiple occasions.
That was what C51 used to do - and the trouble with that was that it couldn't (or just didn't?) give context-sensitive help from within the IDE.
But now the ARM tools don't even do the context-senstive help anymore - so they might as well use PDF!
(and ARM is one of the few companies that does enable annotations on its PDFs)
I found something like these, they are PDF files.
