Where can I read about writing faster C code.
For example, today I saw in a book something about the type double_t that is defined in c99. Apparently this type is optimized for floating point stuff.
I know about inlining and the -O3 flag but there must be more info about this stuff. Like having the compiler unroll loops...
(I compile with gcc on Mac OS X and I plan on always using the -std=c99 flag.)
Thanks,
Peter
