similar to: [PATCH 1/3] Make FLAC__clz_soft_uint32 static.

Hi, attached are patches that improve decoding speed a bit. The first patch improves the bit scan macro used for decoding unary values, the second one adds a GCC inline assembly for bswap and the third patch replaces the read_rice_block function. In my testing it turned out to be even faster than the _ia32_bswap function. If the code produced by MSVC is faster as well, I'd suggest to remove

Pulled from my Arch archive, this following patch seems to have made quite a difference in getting my ARM7TDMI chip to play FLAC (compression levels 0-2) on my ipod. I don't have benchmarks with hard numbers, but playing with skips vs playing without skips is a fairly noticeable difference. memcpy and memset on uClibc are optimized in asm for the ARM7TDMI in uClibc. Other hardware/libc

For llvm-dwarfdump we need to handle relocations inside the debug info sections in order to successfully dump the dwarf info including strings. Nick sent out a partial patch that did this not too long ago and I've taken it and gone in a bit of a different direction, but kept the same basic architecture. In place of applying the relocations to the data we've read from disk I'm keeping

First, I love R and am grateful to be using this free and extremely high quality software. Recently I have been comparing two algorithms and naturally I programmed in R first. It is so slow that I can almost feel its pain. So I decided to do a comparison with Java. To draw 500,0000 truncated normal, Java program takes 2 second and R takes 72 seconds. Not a computer science major, I find it hard

Under the assumption that in these cases recurring faults aren''t a security issue and it can be expected that the drivers there are going to try to take care of the problem.
