similar to: [LLVMdev] ARMv5 Thumb Support Hacking Session (and other topics)

Hi Joe, Not sure yet if I'll be able to make the hacking session or not, but either way, feel free to look me up at any time during the conference and I'd be happy to talk about the arm backend.

I've done a first pass over the past 6 months of changes and some notable things stood out: * The ARM backend has reworked Set Jump Long Jump EH Lowering. * The ARM backend includes improved support for Cortex-M * The ARM backend adds parsing and encoding ARM/Thumb/Thumb2 assembly There are also many many code generation improvements which select more optimal instructions. Those seemed

I have a need to build ld from source to understand an assert(0). I got excited when I found that ld64 on the opensource portal contains an xcodeproj http://opensource.apple.com/source/ld64/ld64-127.2/ But... it seems like I'm lacking mach-o/arm/reloc.h, and dyld_priv.h. I'm doing my best to stitch it all together, but if anyone has any pointers to make this less painful, it would be

what do you mean by "more optimal instructions" ? -omer On Wed, Nov 16, 2011 at 1:28 AM, Joe Abbey <jabbey at arxan.com> wrote: > I've done a first pass over the past 6 months of changes and some notable > things stood out: > > * The ARM backend has reworked Set Jump Long Jump EH Lowering. > * The ARM backend includes improved support for Cortex-M > *

Renato, I was wondering when the videos might be uploaded. The slide material is great! Thanks!

One idea for a hacking session would be a "performance analysis workshop". People could bring their apps, we could sample them track down what part of the compiler would need to change and code it up (if time allowed). Given the trade offs involved, it could be helpful to many folks, the trick is to get the right people to show up. -Chris On Nov 20, 2011, at 2:10 PM, Joe Abbey

David, Sorry I missed the Community Event Planning session. There was this neat session on Backend\Infrastructure competing with it. :) Whiteboards (with markers (and erasers?)). I was speaking with Dan G about the complexities of trying to get the SelectionDAG to represent physical registers. He mentioned during our conversation that a whiteboard would help. Ballroom Salon V would have

Legal... really? :( What a shame. I'll wait patiently, unless I can get a download link... :-D Don't wanna anger legal though...

Hi Joe, I can answer that, as I'm dealing with it J The videos are stuck currently with our legal department. They've gotten extremely sensitive over it and we have had to get Tanya/Chris to agree to a secure dropbox so we can send the videos to them to put on the website (binaries don't live in SVN). Obviously Tanya is very busy with the release at the moment, so it's

Thanks for your response, that's kinda what I've gathered over the years. I was hoping that the Xcode project would have "just worked". I'll keep piece-mealing it together, and hope that it works. I'll try to post a radar. Joe Joe Abbey Director of S/W Development Arxan Technologies, Inc. 1305 Cumberland Ave, Ste 215 West Lafayette, IN 47906 W: 765-889-4756 x2 C:

I'm so close to having LLVM build on PowerPC. If there's any PowerPC experts, help? Lines like this: outs() << "[" << format("%2d", i) << "]" << "(sec " << format("%2d", int16_t(symbol->SectionNumber)) << ")" << "(fl 0x" <<

Please don't be alarmed by the failed compiles on llvm-ppc-darwin. They are likely not your fault. I'm trying to get a PPC build bot setup (arxan_bellini), and so far it's dying here: Linking CXX shared library ../../lib/libgtest.dylib Undefined symbols: "vtable for llvm::raw_ostream", referenced from: __ZTVN4llvm11raw_ostreamE$non_lazy_ptr in gtest.cc.o

I'm the code owner of LLVM codegen and targets. I'm also the one of main developers on the original ARM target. That means, I would make the decisions on major development on ARM target if there are decisions to be made. But my role is very different from what people are looking for in this thread. To properly qualify a target like ARM which are supported on many different CPUs and

I see, so perhaps the LLVM ARM Backend is in need of a method of organizing volunteer qualifiers, as releases near? Has this generally been organized via this mailing list?

Hi John, While this is a good idea, wouldn't it logistically take longer to get the microphone to the person involved than for the presenter to repeat the question?
