2016-05-26Branch to do development of rfc02464, which adds binary floating-point Kelvin Nilsen
support operations for Power architecture. (Restarting this branch with a new trunk, since the new trunk has the P9 bulitin infrastructure.) git-svn-id: https://gcc.gnu.org/svn/gcc/branches/ibm/rfc02464@236800 138bc75d-0d04-0410-961f-82ee72b054a4

2016-05-26GCC expands switch statements in a very simplistic way and tries to use a tableWilco Dijkstra
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). gcc/ * config/aarch64/aarch64.c (aarch64_case_values_threshold): Return a better case_values_threshold when optimizing. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@236771 138bc75d-0d04-0410-961f-82ee72b054a4

2016-05-25This patch adds support for the vec_cmpne altivec builtins from the PowerBill Seurer
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.
