From 83781f11dce6d4ef8da052253454cafcbec80dbe Mon Sep 17 00:00:00 2001 From: Joshua Henderson Date: Fri, 13 Apr 2018 13:22:34 -0700 Subject: [PATCH] sqlite: avoid use of unsupported -Ofast CFLAGS MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit sqlite3 refuses to be built with -ffast-math (a side effect of -Ofast) when it falls back to implementing its own isnan() function. sqlite3.c: In function ‘sqlite3IsNaN’: sqlite3.c:28554:3: error: #error SQLite will not work correctly with the -ffast-math option of GCC. To work around this, when -Ofast is used replace with -O3.
