Sub:-code added by my path profiler module not executing with llvm-gcc -03
When compile with llvm-gcc -O3 the path profile result shows frequency
count of zero for all paths ins some functions
I have four functions insert,delete,print and main. It prints correct
values for delete's and main's paths and zero values for print's and
insert's paths.
This problem occurs only with -O3 option. It is working correctly with
llvm-gcc -O1
I first generated .ll fine using llvm-gcc -O3 and then used opt to insert
path profiling.
Then used llvm-as and llvm-ld -lprofile_rt to get the executable.
Can you suggest what went wrong?
Thanking you
