From 9b541f4f6272c4ed4bb5bf6591e9a65cded6fdfa Mon Sep 17 00:00:00 2001 From: Samuli Piippo Date: Tue, 23 Oct 2018 09:54:57 +0300 Subject: [PATCH] Disable ltcg for host_build debug-prefix-map does not work correctly for static libraries when using ltcg, and since host_build compilations link agaist the libQt5Bootstrap.a library, it breaks source file packaging into debug packages. Also disable ltcg when compiling on Windows host platform, as GCC7 does not support lto with mingw. Disable also for static builds since those libraries can be linked on Windows host, where the lto built binaries won't work.
