Is the program being built by gcc or clang?
Cheers, Rafael

Hi,
for programs linked with lld it's substantially slower to get callstacks in gdb, in comparison to gold-linked programs. Two measurements: lld gold 15 sec 3 sec 6 sec 2 sec Are both using --gdb-index? Can you try lld trunk if so? Is any of the programs you tested open source? Cheers, Rafael
