From 3c5038a535c8a70a23ee8259efab875233732163 Mon Sep 17 00:00:00 2001 From: Ulrich Weigand Date: Thu, 30 Jul 2015 14:08:36 +0000 Subject: Add support for System z vector language extensions The z13 vector facility has an associated language extension, closely modeled on AltiVec/VSX. The main differences are: - vector long, vector float and vector pixel are not supported - vector long long and vector double are supported (like VSX) - comparison operators return a vector rather than a scalar integer - shift operators behave like the OpenCL shift operators - vector bool is only supported as argument to certain operators; some operators allow mixing a bool with a non-bool vector This patch adds clang support for the extension. It is closely modelled on the AltiVec support. Similarly to the -faltivec option, there's a new -fzvector option to enable the extensions (as well as an -mzvector alias for compatibility with GCC). There's also a separate LangOpt. The extension as implemented here is intended to be compatible with the -mzvector extension recently implemented by GCC. Based on a patch by Richard Sandiford.
