[RS6000] strict alignment for little-endian

I'd like to remove -mstrict-align for little-endian powerpc, because the assumption that mis-aligned accesses are massively slow isn't true for current powerpc processors. However I also don't want to break old machines, so probably should add -mstrict-align back for some set of cpus. Can anyone

Testing and branching with different modes

Hello, My port seems to be slightly awkward in testing and branching compared to the existing one in mainline. All the comparisons in my port set a QImode (8bits) register (predicate register), however branches branch on a single bit value of the predicate register. So while I have: tsteqb p0,

Not sure if it is already known, but noticed that at least in the online HTML documentation for all versions since 4.5 (where it was apparently introduced), at in the paragraph Speaking of labels, jumps from one asm to another
