2019-09-19Rework constant subreg folds and handle more variable-length casesRichard Sandiford
This patch rewrites the way simplify_subreg handles constants. It uses similar native_encode/native_decode routines to the tree-level handling of VIEW_CONVERT_EXPR, meaning that we can move between rtx constants and the target memory image of them. The main point of this patch is to support subregs of constant-length vectors for VLA vectors, beyond the very simple cases that were already handled. Many of the new tests failed before the patch for variable- length vectors. The boolean side is tested more by the upcoming SVE ACLE work. 2019-09-19 Richard Sandiford <richard.sandiford@arm.com> gcc/ * defaults.h (TARGET_UNIT): New macro. (target_unit): New type. * rtl.h (native_encode_rtx, native_decode_rtx) (native_decode_vector_rtx, subreg_size_lsb): Declare.

2017-09-25Turn CONSTANT_ALIGNMENT into a hookRichard Sandiford
The definition: #define CONSTANT_ALIGNMENT(EXP, ALIGN) \ (TREE_CODE (EXP) == STRING_CST \ && (ALIGN) < BITS_PER_WORD ? BITS_PER_WORD : (ALIGN)) was very common, so the patch adds a canned definition for that, called constant_alignment_word_strings. Some ports had a variation that used a port-local FASTEST_ALIGNMENT instead of BITS_PER_WORD; the patch uses constant_alignment_word_strings if FASTEST_ALIGNMENT was always BITS_PER_WORD and a port-local hook function otherwise. 2017-09-25 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (constant_alignment): New hook. * defaults.h (CONSTANT_ALIGNMENT): Delete. * doc/tm.texi.in (CONSTANT_ALIGNMENT): Replace with...
