...n-ish globals out there, which is the majority in some of the more "modern" code I've looked at. It leaves the legitimate merging in perl alone. #2 (and even moreso #3) is actually too aggressive, and doesn't catch a lot/most of the profitable cases in perl. Consider: - a "g_log" global (or, say, LLVM's outs/dbgs/errs), used pretty much everywhere - several sets of globals, used in different parts of the program (perl's interpreter vs parser) You'd pick one of the latter sets, and add the "g_log" global to it. Now you made it more expensive ever...

Hi all, I've started looking at the GlobalMerge pass, enabled by default on ARM and AArch64. I think we should reconsider that, at least for AArch64. As is, the pass just merges all globals together, in groups of 4KB (AArch64, 128B on ARM). At the time it was enabled, the general thinking was "it's almost free, it doesn't affect performance much, we might as well use it".

Hi Erik, I've found a middleground for the problem of setting default CFLAGS. I've gone back to setting them if {C,CXX,CPP,LD}FLAGS are unset at the onset of the configure script (i.e., the user hasn't specified anything) and then proceed to set them to the defaults as before. This has been suggested before: https://lists.gnu.org/archive/html/autoconf/2006-04/msg00022.html In

Dear FLAC devs, I would like to get some of our patches merged into master. Most of them deal with adhering to GNU conventions, respectively not overriding flags/variables that are up to the user to set. For instance, honoring $(htmldir) is important, as we have installation paths for the documentation that differ from what is currently coded in the various Makefile.am's. Regards David

Hello Mongrel Users, I''m writing a web server called Ebb. It''s written in C, makes use of the Mongrel HTTP parser, and uses libev its event loop. The goal is to be small, fast, and language independent server that can host web frameworks. I have written a small Ruby binding which provides a Rack handler - this will allow Ebb to host Rails, Merb, and other Ruby frameworks. In the
