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 minigzip binary with normal speed.
Regards
