* Use __builtin_clz instead of default implementation of fixnormz on GCCJakub Stachowski2012-08-141-0/+12
| | | | | | | | | | | | The library contains architecture specific versions of the clz functions for arm and mips, but the fallback C version for other architectures is pretty slow. By using __builtin_clz on GCC (available since GCC 3.4), we get a significant (20-40 %) speedup of the total running time on x86. Speed difference: 5.1 s instead of 8.6 s for AAC-LC 128 kbit/s and 3.8 s instead of 4.9 s for HE-AACv2 32 kbit/s, on an i7.
* Use saturating adds to avoid overflowMartin Storsjo2012-08-111-2/+2
| | | | | When the addition overflowed, asserts were triggered later, where the values were assumed to be non-negative.
* Use saturating adds in all other similar loops in groupShortData as wellMartin Storsjo2012-08-101-3/+3
|
* Don't try to shift more bits than the variable lengthMartin Storsjo2012-08-101-2/+8
| | | | | Shifting by more than (or equal to) the variable length is undefined in C.
* Use saturating adds to avoid overflowMartin Storsjo2012-08-102-3/+3
| | | | These additions can overflow, triggering assertions later.

* build: declare the project foreign to automakeDiego Elio Pettenò2012-07-116-367/+1
| | | | | | By default automake thinks the project is part of GNU and enforces the presence of some files. By declaring the project foreign, we can remove the 0-sized files.

* Don't link to libstdc++Martin Storsjo2012-07-111-0/+5
| | | | | | | While the source is C++, it doesn't use anything from the C++ runtime, so by building with -fno-exceptions -fno-rtti, the dynamic library doesn't have to be linked to libstdc++. This also simplifies things for users of the static library.
* Allow setting bitrate modes 1-5 tooMartin Storsjo2012-07-111-0/+5
| | | | These correspond to different VBR modes.

* Add an _enc suffix to the sbr_ram/rom files in libSBRencMartin Storsjo2012-07-113-2/+2
| | | | | | This avoids name clashes with the similarly named files in libSBRdec, when building all libraries with one single automake file.
