Hi all!
For some time I have been using tremor with fastermdct patch found on
http://www.rockbox.org/wiki/FasterMDCT. This patch gives huge speedup on
i686/x86_64 machines and smaller, but still significant, speedup on ARM.
Everything works great until I compile tremor on ARM with -fPIC flag (I
That's very interesting indeed. I too observed a segfault when trying to use
the fastermdct patch on top of a libtremor used by an MPD server but
couldn't pinpoint the reason. That's one of the reasons this patch hasn't
hit upstream Tremor.
I know the code well but that line seems very mysterious
If I remember correctly, gcc was not clever enough to maintain the ordering
constraints needed by the ldmia/stmia calls, so I needed to assign the
registers manually to prevent generating bad code (by the way x86 shouldn't
use this file at all so compilation issues wouldn't show up on your build).

Ah right, GCC can not be

Hi,
thanks for quick response.

I think the OP should post .S output of gcc and also give
us compiler version and options being used

I think it's hard to tell - let's see what happens without optimisations
(-O0) since the code won't always align easily to the source otherwise.
