[RFC] Add aarch64 support for ada

From: Richard Henderson The primary bit of rfc here is the hunk that applies to ada/types.h with respect to Fat_Pointer. Given that the Ada type, as defined in s-stratt.ads, does not include alignment, I can't imagine why the C type should have it. This causes problems with the AArch64 calling

[PATCH 4/6] Move lowering of vector shifts from v/s to v/v to rtl.

From: Richard Henderson This allows other rtl expanders to rely on shifts of vector by scalar. This replaces the patch posted a couple of days ago that adds these scalar shifts to the rs6000 backend, following the info that Sparc needs this fallback as well. --- gcc/optabs.c

From: Richard Henderson Of course we don't support vectors of size <= 4. We're supposed to be checking the vector element size. --- gcc/config/rs6000/rs6000.c |2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/gcc/config/rs6000/rs6000.c b/gcc/config/rs6000/rs6000.c index 4

[PATCH 0/6] Cleanups for generic vector permutation.

From: Richard Henderson These patches allow __builtin_shuffle to handle any vector permutation via optabs. It allows for a not-uncommon fallback to byte permutation at rtl expansion time, while leaving the tree/gimple-level permutation as element-based. All three targets which heretofore suppor
