Hi
I have one question on LLVM 3.3 profile guided optimizations.
I see in the utils/profile.pl there are supports
for "-insert-block-profiling", "-insert-edge-profiling"
and "-insert-function-profiling", but it seems only
-insert-edge-profiling
is working and the other 2 gets suggested to "-insert-gcov-profiling".
and llvm_start_basic_block_tracing does not seem to be called anywhere in
the LLVM src code.
Thank you,
Trent
