From 8195f696e493508b4784fbf94471e966457931b1 Mon Sep 17 00:00:00 2001 From: Reid Kleckner Date: Wed, 4 May 2016 02:58:24 +0000 Subject: [X86] Add -malign-double support The -malign-double flag causes i64 and f64 types to have alignment 8 instead of 4. On x86-64, the behavior of -malign-double is enabled by default.
