From d79da01631cc1a2566092e0297e5068197d0c6cf Mon Sep 17 00:00:00 2001 From: Sanjay Patel Date: Tue, 2 Jun 2015 16:55:12 +0000 Subject: add the -mrecip driver flag and process its options (2nd try) The first try to land this (r238055) was reverted due to bot failures caused by the LLVM part of the patch. That was hopefully fixed by r238788, and the LLVM patch was resubmitted at r238842. This is the front-end counterpart to D8982. The -mrecip option interface is based on maintaining compatibility with gcc: https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/i386-and-x86-64-Options.html#index-mrecip_003dopt-1627 https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/RS_002f6000-and-PowerPC-Options.html#index-mrecip-2289 ...while adding more functionality (allowing users to specify the number of refinement steps for each estimate type).
