Re: PCH Support

I've added PCH to SOPE 4.5 and it now compiles in ~8mins instead of ~16mins on a PM G5, so it indeed gives a huge speed boost. How to use == First you need to reconfigure/reinstall gstep-make with --enable-pch: ./configure --enable-pch In your projects you create a header file which contains all the files you usually want to include, in SOPE we already had such files called "common.h", eg: common.h: #import #import After that you need to tell gstep-make about that file by adding a new variable: MyProject_PCH_FILE = common.h Thats it. 'make clean all' and it should compile much faster. Notes = - The common.h will be included in _every_ source file of the project at the very top (automagically using -include). This is sometimes confusing and can lead to bugs with non-PCH setups, but necessary to ensure that the PCH actually gets used. - On the first 'make all' the PCH will be generated. Subsequent "touch *.m; make all" are marginally faster (for SOPE 4.5 with ~20 PCH's this is no measurable difference) - The PCH will NOT pick up changes automagically. So you should not add 'volatile' headers to the PCH or you might experience weird effects (old headers getting used). Don't know whether auto- dependencies help here, at least a .d file is generated. - Do not use PCH if your project/subproject has just one or two files. Will gain you nothin' but wasted diskspace. - Precompiled headers are quite big! For SOPE common.h around ~13MB each (~250MB for SOPE). - I have the impression that PCH also increases Dual-CPU saturation on the G5 (w/o using -j), don't know why. Maybe because cpp=>cc1obj pipeline is multitasked and somehow better used. - The newer Xcode's do something called shared PCH. Don't know how this works, I suppose they hash the header-file and only regenerate when they differ. Should save disk-space and some PCH generation time. How to get it = My gstep-make branch is available at: http://svn.opengroupware.org/SOPE/trunk/gnustep-make You can retrieve it as a patch to 1.11.0 using: svn diff http://svn.opengroupware.org/SOPE/vendor/gnustep-make/ 1.11.0 \ http://svn.opengroupware.org/SOPE/trunk/gnustep-make Issues == I have one issue with subprojects, apparently they are run w/o a submake invocation and somehow pick up wrong PCH_FILEs. Nicola, maybe you can look into the changes and tell me what I did wrong? ;-) Another minor issue the patch has is that the PCH must live in the same directory like the makefile - when I use $(notdir), the PCH compilation rule somehow doesn't get picked up (see comments in makefile). I failed to see why (Nicola again ;-) Note: to see this behaviour your main project and your subproject need to use different PCH_FILE names (otherwise the subproject picks the one of the parent). PCH in Sarge gcc4 doesn't work. I won't have the time to run through the full gcc bug-reporting procedure as outlined in: http://gcc.gnu.org/bugs.html If someone would find the time to build/submit a testcase it would be excellent. Greets, Helge PS: ratmice: I think you saw no speed gain because you didn't use - include which you should to ensure that the PCH is actually used (the PCH MUST be the first included header). -- http://docs.opengroupware.org/Members/helge/ OpenGroupware.org ___ Gnustep-dev mailing list Gnustep-dev@gnu.org http://lists.gnu.org/mailman/listinfo/gnustep-dev

Its fairly huge over here. Of course tests on Linux/ix86 are pending and it will be interesting to see whether it gives measurable speedup given that Linux/ix86 is already thrice as fast as my G5 over here.

Cairo backend
Some of you may have noticed that this week the release 1.0 of cairo has been published. For quite some time GNUstep has had a backend based on this graphics library. But this has always been incomplete and also cairo has changed a lot over the months. In the last few weeks I cleaned up the code for this backend and extended it a bit. Basically it is now ready to try it, although many features are still missing. Known limitations: - fonts are still hard coded - text in NSTextView sometimes doesn't get displayed - images are often displayed incorrect - copying from one GState to another uses wrong transformation - some minor operations are missing or untested I hope to solve these problems within the next month and will make a public announcment for the cairo backend after that. If you find other bugs, feel free to report them, or even better help to resolve them. If you want to compile the cairo backend, use the command: ./configure --enable-graphics=cairo --disable-glitz We probably should switch glitz off by default, as this is not offically supported by cairo at the moment Cheers Fred ___ Gnustep-dev mailing list Gnustep-dev@gnu.org http://lists.gnu.org/mailman/listinfo/gnustep-dev
