But surprise, if you report a bug, chances are it will be fixed

Hi,
I found out that GCC 4.4.x build of minigzip from zlib package is a lot slower
compared to GCC 3.4.0 build.
Maybe someone can compile minigzip for his system with GCC 3.4.x and GCC 4.4.x
and compare time of compression
with bigger file? This way we would know if this regression only happens
please correct the Bugreport 40454 with the values of gcc 4.1.2 4.2.5.
it seem 4.1.2 reach near same speed as 3.4.0 but all later gcc are
slower in some programs.
this can also see on ffmpeg. also on X86 ffmpeg see here it is see.
what is change after 4.1.2 that can cause slower executable
Hi,
The problematic source code is deflate.c from libz.
CFLAGS=-O3 -DUSE_MMAP -m68060 -fomit-frame-pointer
When I compile all source code with GCC 4.4.1, I get slow minigzip binary.
When I compile all source code with GCC 4.4.1 except deflate.c (this one I
compile with GCC 3.4.0), I get
