Downloadable Multi-Edit Rules Peg CPU @ 100%

[Guest]

I downloaded the Multi-Edit XML file since I'm currently involved in a CMAC project. Whenever I compare .S files, the CPU pegs @ 100%.

Some experimenting seems to indicate that the problem lies in the first regular expression for line weights. If I delete it, performance is normal.

I'm going to spend some time with the regex when I get a few minutes, but I figured I'd pass this along. The expression is:

^[ \t\r\xFF]*([A-Za-z_$][A-Za-z0-9_$]*)+[ \t\r\xFF]+[A-Za-z_$][A-Za-z0-9_$]*\(

Thanks for the bug report. These were contributed rules, so we haven't tested them, but I've emailed the original contributor, so we should have an updated set fairly soon.

Was there ever any response on this? I just tried a Multi-Edit file compare and ran into this same problem.

That was me, actually.

If you send in a sample of the files that this is having trouble with I can take a look at it. Just guessing based on the regular expression I'd say the correct expression would be this:

^[ \t\r\xFF]*[A-Za-z_$][A-Za-z0-9_$]*[ \t\r\xFF]+[A-Za-z_$][A-Za-z0-9_$]*\(

We did get a reply from the original author, and it must have slipped through the cracks. He said that he's gone back to the standard "C" rules, and I think that's the best thing to do, given the circumstances. The regular expressions that are causing the problem are just for line weights, and I don't think deleting them will significantly affect the alignment. So, if you've downloaded the Multi-Edit rules and are having trouble, just delete them and add "*.sh;*.s;*.db" to your "C/C++ Source" rules. We'll pull the Multi-Edit rules from the website later today.

Thanks for the work.

By the way, the .db files are binary files and seem to be handled well by the rule "Multi-Edit Database". But yes, .s and .sh files are handled fine using the C/C++/C## Source rules.
