Re: [webkit-dev] squirrefish extreme on Arm.
Hi all. I have been studing about squirrefish extreme for last several days but can't find answers to several quations I need. 1. How can I dump compiling process? For instanance in GCC I can compile with -da -fdump_tree_all and then get all passes up to assembler generation. So is there any way to do the same on squirrefish extreme ? I wanna to see which optimizations are works in each state. And finaly how can I get bytecode from my source. I built webkitv with --debug option and tried to run ./jsc-3 sunspider -d, but it didn't give bytecode -- View this message in context: http://old.nabble.com/squirrefish-extreme-on-Arm.-tp32876913p32880353.html Sent from the Webkit mailing list archive at Nabble.com. ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] squirrefish extreme on Arm.
-d should work fine on ARM - check your build settings, is any #ifndef NDEBUG code getting built? In addition there are a set of switches in dfg/DFGCommon.h that include ones to enable further dumping of the intermediate representation. G. On Nov 29, 2011, at 2:51 AM, vahagvahag wrote: Hi all.

[webkit-dev] squirrefish extreme on Arm.
Hi all. I didn't find any documentation about porting squirrefish extreme on Arm. I tried to google it, and found some posts where said that there is squirrefish extreme on Arm, but I can't find source cod,or any documentation about it( Can anybody help me. Any information about squirrefish extreme is important for me:) p.s I download latest code of webkit from offical site by svn and built it under x86_64. In source code I didn't find any squirrefish extreme I think that squirrefish extreme source code is in javaScriptCoe folder.

Re: [webkit-dev] squirrefish extreme on Arm.
Hi, WebKit supports ARM and Thumb2 instructions sets (called ARMv7). You can find them here (or in your own source code): http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/assembler SquirrelFish Extreme is just a codename for the JavaScript JIT compiler (and Nitro is another). The JIT compiler is enabled by default on most OS-es, just compile WebKit and you have it. Regards, Zoltan Hi all. I didn't find any documentation about porting squirrefish extreme on Arm.

Re: [webkit-dev] squirrefish extreme on Arm.
Thanks a lot for reply. but can I Cross-compile webkit on my x_64 machine so I can use it on my armv7 machine?? And I can't find any documentation about squirrelfish back-end, optimizations passes and so on. Currently I'm diong optimizations on Gcc compiler, and now I wanna to start developing squirrelfish, and tring to understand how can do optimizations on it. But unfortantly i can't find usefull information about squirrelfish( So if you have any documentation about it can you please help me?? -- View this message in context: http://old.nabble.com/squirrefish-extreme-on-Arm.-tp32876913p32876949.html Sent from the Webkit mailing list archive at Nabble.com. ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

Andy Wingo wrote up a nice piece about the DFG optimizing compiler: http://wingolog.org/archives/2011/10/28/javascriptcore-the-webkit-js-implementation The code and design are in constant flux; the best way to really learn about it is to read the code.
