...like to insert the function in the same > bytecode, how to do it? In the above example, you would generate a bytecode version of libprofile using the standard Makefile, then link it with the bytecode version of your program using gccld or llvm-link. > 3) for opt commamnd, there have -trace -tracem options > ,how can I see the detailed direction to use it. Short answer: 1. Compile the program in question to bytecode using llvmgcc. Assume the result is 2. Run the bytecode of the program through opt -tracem, and then generate C code for the result. % opt -tracem bytecode.llvm.bc | llc -...

...I insert the external call function to existed bytecode ? if it is valid. Can you give me a simple example to show how to do it or just give me a url which can show how to do it? 2) If I'd like to insert the function in the same bytecode, how to do it? 3) for opt commamnd, there have -trace -tracem options ,how can I see the detailed direction to use it. I went through a LowerInvoke.cpp and EdgeCode.cpp file which have examples to do what I want. Although I can learn the main flow how to insert a call funcation or instruction, but I still cannot implement it. Shame. Another thing is that I a...

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->tr...

...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
