In my monster benchmark, 12 of 13 seconds of gdb startup time (the time to get to the prompt) is due to reading ELF symbols. If I comment out the generation and storage of demangled copies of ELF symbols, then startup time reduces to 2.5 seconds. This is enough to make me seriously want to implement something along these lines. -- You are receiving this mail because: You are on the CC list for the bug.
