similar to: CTF generation

OK, I am trying to dtrace isp(4) module in freebsd 7. each obj file is converted using: ctfconvert -L VERSION isp_freebsd.o and using "ctfdump isp_freebsd.o" I can see CTF info embedded in the .o file but in the linked kernel module, I found much less CTF info inside it. I guess I should use "ctfmerge" to combine the CTF info from each obj file into the final kernel module,

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 Dean, I haven't looked very closely at XRay so far, but I'm wondering if making CTF (common trace format, e.g. see http://diamon.org/ctf/) the default format for XRay traces would be useful? It seems it'd be nice to be able to reuse some of the tools that already exist for CTF, such as a graphical viewer (http://tracecompass.org/) or a converter library

This is a belated heads up to let you know that I have merged DTrace to the releng7 branch in the nick of time before the feature freeze for 7.1. Those astute mailing list readers will note that the commit message appears to have gone missing. Well, either the dog ate it or subversion decided that it was for certain eyes only (and not yours, or mine). I have added a note to src/UPDATING

Is it possible to use dynamic library (*.so *.dll) from bytecode? If "yes" - how? -- WBR, Yaroslav Kavenchuk.

Hello, I'm having troubles with writing a pass. In my pass I've have created a function that has two parameters - both of type i8*. Initially I wrote this function in C, that I translated it into IR, and then by using llc -march=cpp I got it's implementation in cpp code that actually inserts IR instructions. Then, I inserted this cpp code in my pass. And in some places of a program

Hi, ctfconvert is particularly unhappy about that (e.g., ERROR: ctfconvert: die 141: base type without name). Is it intended behavior? Simple testcase: int main(void) { int i[2]; return 0; } dwarfdump output: clang version 3.0 (tags/RELEASE_30/final): [...] LOCAL_SYMBOLS: [...] <3>< 120> DW_TAG_variable DW_AT_name i

And after that for all the BB you have visited more than once, you try to find a parent that has a branch instruction as a terminator. Additionally you ensure that there are no BB with branches as terminators on your way. If such

Dear R Developers, Recently filed (and dismissed ;) ) law suit by Astrolabe against tz database developers caused a lot of media-press and discussions and created some kind of precedence in the USA [3]. But also it imho showed that similar attacks might happen in the future, and possibly against data sets which are not that obviously "factual" thus after all might fall under copyright

Hello, I have the following problem: I need to allocate an array. I know it's size - it's constant (ConstExpr), but my problem is that I know it only during the runtime (i.e for every variable I'm trying to allocate an array equal to size of a variable). As I understand I can't do it, since it's possible to initialize ArrayType only if I know it's size in integer units.

Dear Rsyncers, I'm trying to maintain a mirror of Ubuntu distribution and I had a cron job which rsynced it every night. The problem came after last reboot a few days ago -- destination directory wasn't mounted, thus wasn't accessible by rsync for writing: rsync: failed to set times on "/share/ubumirror/.": Operation not permitted (1) rsync: recv_generator: mkdir

Way back in r107027, we started preserving type information of local variables of functions that are optimized away. This seemed strange to me so I dug into the history: apparently, this is so that ctfconvert can find these types (so they can be exposed in dtrace). E.g., this commit made it so that for this C code: static void foo(void) { struct X { int b; } v; } we always get the type

everyone, Just out of curiosity, I did a dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }'' and looked at the entries produced by ''rm''. I see everything that rm did, *except* the unlinkat - which is unfortunate because I want to trace which processes have deleted which files. So - does dtrace contain unlinkat as a probe for a system call?
