Bug Description
Binary package hint: binutils
Binutils does not support 64-byte alignment for armel platforms using the .p2align directive; this is required in order for GCC to use this alignment (wiether via -falign-functions= etc. or __attribute__ (( __aligned__ (64) )). This may be affecting performance on Cortex-A8 processors and later, since it is not possible to align functions or data to the native cache line size (i.e., 64 bytes).
CodeSourcery have implemented the necessary support in binutils for 64-byte alignment, but I'm currently waiting for confirmation of a patch having been published for this.
I'll add a link to the relevant patch when it becomes available.
