I recommend that you look at the various pieces of code under llvm/lib/Transforms/Instrumentation, e.g. BlockProfiling.cpp and TraceBasicBlocks.cpp. They do essentially the same thing as you are trying to do. > 1) I implement call function in another c/cpp file and >

Hi llvmer, I am trying to learn how to use llvm. My question is described as the following, there has already a testcase code, and I get bytecode by using llvmgcc. What I want to do is to insert a call funcation into each basic block, which is for statistic some information. 1) I implement call function in another c/cpp file and can I insert the external call function to existed bytecode ? if it

Hi, Thank Brian Gaeke so much. Following TraceBasicBlocks.cpp, I modified the code as below and could insert instruction or function I need into anywhere in Module. But it works well without BB->getInstList().push_back(InstrCall), and if I add the BB->getInstList().push_back() following new CallInst(), I got error information when runing opt. What is the reason for it? And is it necessary

In order to get more information on IO performance problems I created the script below: #!/usr/sbin/dtrace -s #pragma D option flowindent syscall::*write*:entry /pid == $1 && guard++ == 0/ { self -> ts = timestamp; self->traceme = 1; printf("fd: %d", arg0); } fbt::: /self->traceme/ { /* elapsd =timestamp - self -> ts; printf(" elapsed : %d" , elapsd); */ printf(" timestamp : %d" , timestamp); } syscall::*write*:return /self->traceme/ { self->tra...

...ot strictly needed; I was just hoping to use it in order to profile idle time.) Here''s the story. I''ve written a dtrace script to start a separate dtrace process for each invoked command: int fileid; proc:::exec-success /pid == $target || progenyof($target)/ { self->traceme = 1; @proc[execname] = count(); } /* This should fire AFTER libc has been dloaded. */ syscall::setcontext:entry /self->traceme/ { self->traceme = 0; stop(); system("dtrace -q -s /export/home/dds/src/dtrace/libc.d -o /export/home/ dds/src/dtrace/data/%07d-...

Hi, Earlier this year I "upgraded" from wine 20010510 to 20011226 in order to see if some kind of resource leak was fixed which caused screen redraws to get progressively slower and slower and slower and slower, .... That was fixed but there seemed to be a significant number of graphics and UI regressions. I've just upgraded to 20020228 to see if things were any better and within
