Hi Arnaldo,
YES, I need further help.
I have published in [1] numbers for "perf stat make ..." with GNU/gcc+binutils vs. LLVM toolchain for building Linux v5.8-rc7.
[ GNU/gcc+binutils toolchain ]
10964.876434769 seconds time elapsed
29666.464675000 seconds user 2149.943729000 seconds sys
[ LLVM toolchain ]
17149.393417675 seconds time elapsed
47787.158036000 seconds user 2289.196142000 seconds sys
How can I dig further to see why the time for user is higher when building with LLVM toolchain? Any suggestions?
Thanks.
