| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4-operation form is preferred over 3-operation because it breaks a long dependency chain, thus allowing a superscalar processor to execute more operations in parallel.

| * avutil: Add functions for allocating opaque contexts for algorithmsMartin Storsjö2012-10-11
| | | | | | | | | | | | | | | | | | | | | | | | The current API where the plain size is exposed is not of much use - in most cases it is allocated dynamically anyway. If allocated e.g. on the stack via an uint8_t array, there's no guarantee that the struct's members are aligned properly (unless the array is overallocated and the opaque pointer within it manually aligned to some unspecified alignment).

* | md5: consistently use uint32_t instead of unsigned intGiorgio Vazzana2012-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically to make code clearer and adherent to the standard. RFC 1321, on page 2 states Let the symbol "+" denote addition of words (i.e., modulo-2^32 addition). Let X <<< s denote the 32-bit value obtained by circularly shifting (rotating) X left by s bit positions. on page 3, section 3.3 states: A four-word buffer (A,B,C,D) is used to compute the message digest. Here each of A, B, C, D is a 32-bit register. so the algorithm needs to work with integers that are exactly 32bits in length. And indeed in struct AVMD5 the MD buffer is declared as "uint32_t ABCD[4];", while in the function that performs the block transformation the state variables were "unsigned int"s. On architectures where sizeof(unsigned int) != sizeof(uint32_t) this could be a problem, although I can't name such an architecture from the top of my head. On a side note, both the reference implementation in RFC 1321 and the gnulib implementation (used by md5sum program on GNU systems) use uint32_t in the transform function.
