GCC expands switch statements in a very simplistic way and tries to use a table...
GCC expands switch statements in a very simplistic way and tries to use a table
expansion even when it is a bad idea for performance or codesize.
GCC typically emits extremely sparse tables that contain mostly default entries
(something which currently cannot be tuned by backends). Additionally the
computation of the minimum/maximum label offsets is too simplistic so the
tables are often twice as large as necessary.
The cost of a table switch is significant due to the setup overhead, the table
lookup (which due to being sparse and large adds unnecessary cachemisses)
and hard to predict indirect jump. Therefore it is best to avoid using a table
unless there are many real case labels.
This patch fixes that by setting the default aarch64_case_values_threshold to
16 when the per-CPU tuning is not set. On SPEC2006 this improves the switch
heavy benchmarks GCC and perlbench both in performance (1-2%) as well as size
(0.5-1% smaller).

This patch adds support for the vec_cmpne altivec builtins from the Power...
This patch adds support for the vec_cmpne altivec builtins from the Power
Architecture 64-Bit ELF V2 ABI OpenPOWER ABI for Linux Supplement (16 July
2015 Version 1.1). There are many of the builtins that are missing and this
is part of a series of patches to add them.
There aren't instructions for vec_cmpne so the output code is built from other
built-ins that do have instructions which in this case is the following.
vec_cmpneq (va, vb) == vec_nor (vec_cmpeq (va, vb), vec_cmpeq (va, vb))
The new test cases are executable tests which verify that the generated
code produces expected values. C macros were used so that the same
test case could be used for both the signed and unsigned versions of various
basic types. A separate executable test case is used for the long long versions
of vec_cmpne because of some differences in loading and storing the vectors.

Clean up PURE_SLP_STMT handling
The vectorizable_* routines had many instances of:
slp_node || PURE_SLP_STMT (stmt_info)
which gives the misleading impression that we can have
!slp_node && PURE_SLP_STMT (stmt_info). In this context
it's really enough to test slp_node on its own.
There are three cases:
loop vectorisation only:
vectorizable_foo called only with !slp_node
pure SLP:
vectorizable_foo called only with slp_node
hybrid SLP:
(e.g. a vector that's used in SLP statements and also in a reduction)
- vectorizable_foo called once with slp_node for the SLP uses.
- vectorizable_foo called once with !slp_node for the non-SLP uses.
Hybrid SLP isn't possible for stores, so I added an explicit assert
for that.
I also made vectorizable_comparison static, to make it obvious that
no other callers outside tree-vect-stmts.c could use it with the
!slp && PURE_SLP_STMT combination.
Tested on aarch64-linux-gnu and x86_64-linux-gnu.

Avoid unnecessary peeling for gaps with LD3
vectorizable_load forces peeling for gaps if the vectorisation factor
is not a multiple of the group size, since in that case we'd normally load
beyond the original scalar accesses but drop the excess elements as part
of a following permute:
if (loop_vinfo
&& ! STMT_VINFO_STRIDED_P (stmt_info)
&& (GROUP_GAP (vinfo_for_stmt (first_stmt)) != 0
|| (!slp && vf % GROUP_SIZE (vinfo_for_stmt (first_stmt)) != 0)))
This isn't necessary for LOAD_LANES though, since it loads only the
data needed and does the permute itself.
