--- Comment #11 from Petr Sumbera <sumbera at volny dot cz> --- I wonder if '-flto' is really needed to avoid this memcpy call. Now gzip 1.4 compiled with GCC 15.2 with CFLAGS="-flto -O3 -funroll-loops -mcpu=niagara4 -mtune=niagara4" will decompress gcc-15.2.0.tar.gz in about 9,955s (before I started this bug it was 13.155s). And Studio can do this in about 8,011s. But with '-flto' I'm not able to reasonable mix objects to find out more details...
