* Remove word_mode hack for split bitfieldsRichard Sandiford2016-06-082-42/+21
| | | | | | | | | | | | | | | | | | | | | This patch is effectively reverting a change from 1994. The reason I think it's a hack is that store_bit_field_1 is creating a subreg reference to one word of a field even though it has already proven that the field spills into the following word. We then rely on the special SUBREG handling in store_split_bit_field to ignore the extent of op0 and look inside the SUBREG_REG regardless. I don't see any reason why we can't pass the original op0 to store_split_bit_field instead. Tested on aarch64-linux-gnu and x86_64-linux-gnu. gcc/ * expmed.c (store_bit_field_1): Do not restrict a multiword op0 to one word if the field is known to overlap other words.

* This patch adds support for the missing versions of the vec_mul altivec...Bill Seurer2016-06-077-9/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the missing versions of the vec_mul 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 the {un}signed char, {un}signed short, and {un}signed int versions of vec_mul so the output code is built from other built-ins and operations that do have instructions. The new test case is an executable test which verifies that the generated code produces expected values. C macros were used so that the same test case could be used for all the various supported types. Bootstrapped and tested on powerpc64le-unknown-linux-gnu and powerpc64-unknown-linux-gnu with no regressions. Is this ok for trunk?
