[LLVMdev] Counting instructions in MCJIT
...;STATISTIC(EmittedInsts, "Number of machine instrs printed");"
I don't know exactly about parallel code generation environment but
this option seems like to work correctly in common case as following.
This is an example from http://llvm.org/docs/DebuggingJITedCode.html.
1 int compute_factorial(int n)
2 {
3 if (n <= 1)
4 return 1;
5
6 int f = n;
7 while (--n > 1)
8 f *= n;
9 return f;
10 }

17 char firstletter = argv[1][0];

[LLVMdev] Counting instructions in MCJIT
Hi there,
I wondered whether anyone could give me any advice about counting
assembly instructions when using MCJIT?
For performance regression testing I would like to be able to count the
number of instructions generated during the jit compilation of a given
module.
The Statistic class, as far as I understand, cannot collect this data
per-module (per-ExecutionEngine/per-MCJIT), and there is
