Hi All, I'd like to inquire about the future of MIPS and SH4 assemblers. A long time ago we had buildbots for MIPS and SH4 platforms (hosted by Holger). But their last builds were at 29th June, machine were stopped, bots were removed from build.webkit.org (2 months before!). Is there anyone

Hi All, We are working on updating WebKit MIPS support. In particular we have a work in progress LLINT and DFG implementation for MIPS. We already have results (mozilla testsuite, sunspider and v8 benchmarks run reasonably well), but there are still some bugs that need to be fixed before we can

Good for me. Thanks for helping us. This will help to the buildbot maintainers as well, since if a patch cause a break where all of our names are CC'ed, they can just disable the JIT until the fix is landed. I think the several ports of JSC is something we should be proud of and I hope we can keep

The problem is that as we make changes we end up breaking the SH4, MIPS, ARMvOld builds, which we are ostensibly not allowed to do, and so have to spend significant amounts of time trying to ensure that the builds don't break/start failing horribly, and then having committed the patch[es] we

Is there a way to reduce these costs other than deleting the slower-maintained JITs? For example, could we temporarily freeze the JIT (perhaps the whole JSC engine somehow) at old versions somehow for architectures that may take time to catch up? Regards, Maciej On Jun 22, 2012, at 10:52 AM,

That would be the ifdef hell we currently deal with. One option (that would keep everything building till appropriate people have fixed whatever needs to be fixed) would simply be to disable the JIT for effected platforms everytime something changes that is too difficult for us to blindly

True, most of the changes are trivial. The problem is that the changes are usually appear without prior notice. A patch which depends on new macro assembler instructions, will obviously break the build, and we are not necessary there to fix it immediately. I think most improvements require time to
