...a debugger attaches so that it can generate the relevant information on the fly. It would be great if the debugger experts (and particularly anyone who has experience on both the debugger and the JIT side of things) could weigh in on these issues. In particular: (1) Is there a reason we bake the vmaddrs into the object file headers, or could they just as easily be passed in a side-table so as to keep the object untouched? (2) Is there a canonical way for the debugger to communicate to a JIT that it's interested in inspecting the JIT's output? If we're going to use breakpoints (or som...

I have a script where I can freely reference struct nameidata*, struct vnode*, etc. on Snow Leopard. How does DTrace know about these data types? I understand things like #pragma D depends_on library darwin.d where darwin.d has typedefs. I can''t find definitions of nameidata and vnode in any D scripts, though. How does it work? Thanks, Joel --- firefox for android!

Hi Kent, My guess is you are getting some new bit of info in your object files and your ranlib(1) is older and doesn't know about it. If you can send me the .o file or the output of otool(1) with the -hlv options on your object file I can take a look. Kev P.S. you can find out the version of ranlib(1) you have by running strings(1) on it and grep(1)'ing for the string

Ran into this today -- rebuilt the SVN Trunk for this morning of LLVM+CLANG. Now every time my builds try and make a library from .o files, ranlib complains about 'malformed object' files. This is with OS X 10.7.4, and the binary tools from XCode 4.4.1 ld -v @(#)PROGRAM:ld PROJECT:ld64-127.2 llvm version 3.0svn, from Apple Clang 3.0 (build 211.12) ranlib doesn't tell you what

Currently, local and remote TLB flushes are not performed concurrently, which introduces unnecessary overhead - each INVLPG can take 100s of cycles. This patch-set allows TLB flushes to be run concurrently: first request the remote CPUs to initiate the flush, then run it locally, and finally wait for the remote CPUs to finish their work. In addition, there are various small optimizations to avoid
