libopus: asm C_MUL for coldfire 2014-07-13T09:49:34+00:00 Nils Wallménius nils@rockbox.org 2014-07-13T09:49:34+00:00 888e05ec12f573cfbef0d331888e68808763a84b The recent merge of upstream changed the fft to use C_MUL which wasn't implemented in asm for coldfire. Speeds up decoding 64 kbps test file by 2.68 MHz and 128 kbps test file by 2.80 MHz on H300. Change-Id: I8b61fc0f9568d6350431e311a12e44fe4f60f72e 
The recent merge of upstream changed the fft to use C_MUL which
wasn't implemented in asm for coldfire.

Speeds up decoding 64 kbps test file by 2.68 MHz and 128 kbps
test file by 2.80 MHz on H300.

Allocations are switched from using the pseudostack to using the real stack. Enabled hacks to reduce stack usage. This should fix crashes on sansa clip, although some files will not play due to failing allocations in the codec buffer.
