[build][classlib] Classlib build and performance.
Guys,
we are talking a lot about performance last few days...
But it is impossible to build release version of the class library
native code :(
This is absolutely needed feature if we want to talk about performance.
Is there any volunteers in build system gurus who wants to fix the
corresponding JIRA [1]? :)
SY, Alexey

But MSDN says that -Zi is incompatible with the most of optimizations.
And I believe that it switch incompatible optimizations off.
Anyway. Let's stop reading docs...
Removing of -Zi option and $(VMDEBUG) variable from Windows make files
increasing JFCmark score by 5-10%!

Oh and BTW, on Linux there are no debugging flags at all. The -g option
has to be added to rules.mak and makefile.include for debug build.

The option doesn't help much if pdb files are not copied to bin
directory. Debugger just cannot find them.
Also while compiler generates some debugging info with -Zi, compiling
with lots of optimizations (-Ogityb1) makes debugging quite hard because
lots of local variables are optimized out, and their values cannot be
seen in debugger. I have to remove these optimization flags when I need
to debug classlib natives.
So classlib mode is release with some debug information. I think these
two modes should be separated for convenience, and pdb files should be
copied to deploy/jdk/jre/bin.

Is that so? What about -Zi msvc option in makefiles?

I believe classlib natives compile in release mode by default. Could
