Hi, We have a problem concerning LLVM optimizations and overflows in MacRuby. I reduced that to the following (architecture x86-64): $ cat e.c #include <stdio.h> long foo(void); int main() { const long a = foo(); const long b = foo(); const long res = a * b; fprintf(stderr, "0x%lx 0x%lx 0x%lx 0x%lx\n", res, a, b, res / a); return 0; }...

...s we avoid the cases where dynamically generated code invokes window management functions. We have tried with both NoFramePointerElim set and cleared, it doesn't seem to make a difference. Has anybody else run into a similar stack trace? I have not found much through Google, but there's a MacRuby ticket with a very similar stack trace : http://www.macruby.org/trac/ticket/427. This was closed as "worksforme", but the original poster indicated it was still failing for him, although only on one particular machine. This suggests the problem may depend on the specific version of LLVM j...

does somebody use XCode on Mac for RoR instead of TextMate? I wonder how is it compared to TextMate... TextMate uses the default font of Monaco... the Xcode screenshot on Wikipedia uses Courier... I wonder if Xcode looks as good as TextMate when the font is changed to Monaco as well? Thank you. -- Posted via http://www.ruby-forum.com/.

i''ve been reading docs and blundering my way through a simple puppet client/server setup between two test hosts (puppetmasterd on server 10.5.8, puppet client on client 10.6.2) and am wondering if there''s any current definitive guide for configuring puppet for os x systems. it also seems the gems installed on my client with ruby 1.9.1 as default don''t work very well

...ssembler, disassembler, and other machine code technology from the LLVM target descriptions. One of the things I'm really excited to see is the number of external projects that are applying LLVM technology in interesting new ways. The release notes lists two Ruby implementations (Rubinius and MacRuby), the Pure language, the LLVM D Compiler, the Roadsend PHP compiler, Unladen Swallow (Python) and LLVM-Lua. These projects show an amazing breadth of different languages adopting LLVM as their shared optimization, code generation, and JIT technologies (depending on the project). Besides open sour...
