--- Comment #21 from sudi at gcc dot gnu.org --- Author: sudi Date: Tue Mar 20 10:54:42 2018 New Revision: 258677 URL: https://gcc.gnu.org/viewcvs?rev=258677&root=gcc&view=rev Log: [ARM][PR82989] Fix unexpected use of NEON instructions for shifts This patch fixes PR82989 so that we avoid NEON instructions when -mneon-for-64bits is not enabled. This is more of a short term fix for the real deeper problem of making an early decision of choosing or rejecting NEON instructions. There is now a new ticket PR84467 to deal with the longer term solution. (Please refer to the discussion in the bug report for more details).
