I think the patch wouldn't compile on ARM because I missed the ldmia ordering constraints like Dave mentioned otherwise I see that fft8_dispatch only differs on 1 register (-fPIC use r9 and without it uses r10==sl) but I don't see r10/sl being used as a pointer.. perhaps it's only done at linking phase? BTW building gdb should be as simple as: ./configure --target=arm-none-linux-gnueabi ; make -- Rafaël Carré
