Here's how I did things, back when I got to write my own infrastructure. It's still O(n^2) in the worst case, but *much* quicker in the expected case. Number all the basic blocks, 0 to n-1 and build a vector mapping from integer to block. Requires O(n) time and space. For each block, compute the set containing it's dominance frontier, based on Figure 10 of * * *Efficiently

I am trying to pipe the output from a process into syslog using the logger command. Initially I pipe the output into a separate file, but as it happens this filled up the disk when things went wrong. So I figured I redirect the output to syslog and let logrotate deal with the roll-over and archive of the file. However the following command : echo "HI" > logger -t test Resulted in

I find a bug in document llvm/docs/WritingAnLLVMPass.html#debughints Since the PassManager class is in the namespace llvm, we should use command (gdb) break llvm::PassManager::run to set breakpoint. Otherwise we get error message: (gdb) break PassManager::run Can't find member of namespace, class, struct, or union named "PassManager::run" Hint: try

I am trying to symbolically execute LLVM assembly language. I found a possible semantic inconsistancy of the LLVM assembly language, or maybe my understanding is wrong. The C code is: #include <stdlib.h> 1 int f(void) 2 { 3 int a; 4 int *b = (int *) malloc(3*sizeof(int)); 5 a = 3; 6 return 0; 7 } I compile it with llvm-gcc 4 front end. The generated
