It works the same as CHECKED_ALLOCZ except that it does not zero the allocated

63826ceb32 intreadwrite: ensure arch-specific versions are always used if defined 
The per-arch headers can define any combination of B/L/N variants.
This ensures that whatever is defined in an arch header gets used
for all equivalents not defined there.  E.g. on a little-endian
machine, AV_RN and AV_RL should give the same code.

d468ff0fdf Fix cast of byte buffer to uint32 that was disregarding alignment 
requirements.
Now calculates crc byte at a time until aligned, then continues with uint32
optimized calculation.
This fixes crashes during mlp decoding on sparc (at least, maybe others).

9f5ff83f2a PPC asm for AV_RL*() 
PPC is normally big endian but has special little endian load/store
instructions.  Using these avoids a separate byteswap.  This makes the
vorbis decoder about 5% faster.  Not much else uses little-endian
read/write extensively.

GCC generates horrible PPC code for the default AV_[RW]B64 (which uses
a packed struct), so we override it with a plain pointer cast.

3c55ce039d ARM asm for AV_RN*() 
ARMv6 and later support unaligned loads and stores for single
word/halfword but not double/multiple.  GCC is ignorant of this and
will always use bytewise accesses for unaligned data.  Casting to an
int32_t pointer is dangerous since a load/store double or multiple
instruction might be used (this happens with some code in FFmpeg).
Implementing the AV_[RW]* macros with inline asm using only supported
instructions gives fast and safe unaligned accesses.  ARM RVCT does
the right thing with generic code.

This gives an overall speedup of up to 10%.
