b18ec0b08d Reworked the static modes. Now, if all static modes have the same frame size, 
overlap or number of channels, we can pass the hint to the compiler.

949902fd1b const correctness. celt_mode_create() now makes a copy of the static mode 
(if STATIC_MODES is defined) instead of attempting to modify read-only
storage.

3e08a88389 Only the (rising) overlap part of the window is stored now. No need to hold the 
zeros and ones (nor even the second half).
 2008-03-03 13:49:20 +11:00

81b38c2295 Moved mdct state and window to the mode so it can be shared between multiple 
encoders and decoders.

a85657bd29 removed // comments and added stack_alloc.h (not used everywhere yet) 
to make the code more C89-friendly.

4c6bc884c8 "make check" now actually tried to encode and decode to see if things work 
(need to have test files installed otherwise it'll just pass by default)
