Re: [PATCH] PPC32 Linuxthreads Chance MALLOC_ALIGNMENT for VMX


This becomes a bigger issue in the future when autovectorization becomes
available (gcc-3.5+). Here "normal applications" using "standard types"
may be using VMX instructions.


Something to consider anyway.

Well, not all auto-vectorized code will use malloc'ed memory, so GCC will have to handle the misalignment issues in a more general way anyway; I don't see VMX-aligning all malloc'ed memory will buy us much for this?
