You know you wrote that code originally? ;-)

Yeah, I agree, it's more reasonable. Updated webrev:
http://cr.openjdk.java.net/~ihse/JDK-8142909-hotspot-build-infra-integration/webrev.02

I don't like this particular change as it is too generic. It gives the appearance of being apply to apply whatever the BUILDARCH specific optflags are, which makes no sense if the whole point here is to not optimize these files. If all this is intended to do is include -g then I think that should be done explicitly.

The -g flag is added to OPT_CFLAGS/$(BUILDARCH) and I can only assume the intention was to have it added to all compilation command lines. However, the OPT_CFLAGS/<filename> variable overrides CFLAGS/$(BUILDARCH), effectively removing the -g flag from the files where we explicitly change the optimization level. The patch intends to make sure -g is used on those files too.

A cleaner solution would be to not have -g be part of the OPT flags at all but its own set of DEBUG_CFLAGS.

make/bsd/makefiles/saproc.make

! # Order src files alfabetically

That would be "alphabetically". But that list doesn't seem alphabetic anyway: MacosxDebuggerLocal.m would come after libproc_impl.c; and $(AGENTDIR) should come first. I really see no point in forcing such lists to be in alphabetic order.

This is to make comparison of binaries between the old hotspot build and the new hotspot build easier. In build-infra, we $(sort ) the object files before linking to get a reproducible order. The linker output is affected by the order of the object files. By making sure the old and the new build sorts them the same way, we get cleaner comparisons and can more easily detect other types of differences through those comparisons. The sort order isn't strictly alphabetical, it's on byte order so upper case goes before lower case.

make/linux/makefiles/saproc.make doesn't have the comment that was added for bsd.

make/solaris/makefiles/amd64.make

Similar issue with bsd amd64.make. Not sure what you are trying to achieve here - is it some kind of last option wins situation ?

make/windows/create_obj_files.sh

Harmless I guess but not sure about relevance of sort order here.

 src/share/vm/adlc/adlparse.cpp

So that's where that comes from! :)

---

src/share/vm/gc/g1/g1EvacStats.cpp

I don't see anything in the cpp files that uses anything from the atomic class ???


Thanks,

Otherwise looks good.

In the new hotspot build project, we have made a few changes to the
existing build. In preparation for the new build, I'd like to
integrate these into mainline.

These changes are:
* When overriding optimization, do not lose current debug (-g)
setting (!)
* Make adlc actually quiet in quiet mode
* Make g1EvacStats.cpp compile in all cases without precompiled headers
* Sort saproc object files when linking (facilitates comparison to
new build)

Unless someone suggests otherwise, I intend to push this (using JPRT)
to hs-rt.
