[M3devel] cm3cg coverage/profiling features?

[Jay K]

Note that this probably isn't the coverage/profiling I was talking about.I was talking about specifically in the gcc backend.
I wonder if coverage -- a boolean per basic block; or maybe a counter,is cheap enough that we can't have it always enabled.
And then some way of exposing it.
I don't like having to recompile/relink everything multiple differentways to get all the features.

Hi, Thought I better upload my coverage fixes I've had sitting around for awhile. So they are in git if anyone cares to (ab)use them. I modified report_coverage to use signals as I couldnt get the old code to work. I'm not sure it will work on all platforms or indeed on 32 bit machines so if anyone with more expertise wants to fix it please do.Just to refresh the usage if you want coverage analysis compile with -Z then when you run your program you get a default coverage.out file which you run analyze_coverage -L for line number coverage (or -P for procedure coverage) see the analyze_coverage.h file for options . Should probably rewrite this stuff in m3.

I wasn’t aware this had changed.When was this regression introduced?

For instance, cm3 used to keep on compiling files after errors were found. Now it seems to stop after one module. That loss of functionality seriously reduces productivity. I couldn't find any switch to reverse the change. When was this change decided? Is there a way to restore it?
