From dec20a987b40e7625b38e520cc223723da9bae2a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Verschelde?= Date: Wed, 3 Oct 2018 17:27:22 +0200 Subject: [PATCH] Fix some warnings raised by MSVC 2017 Disabled signed/unsigned warnings like for GCC/Clang (warning C4018: '>=': signed/unsigned mismatch). Fixes the following MSVC 2017 warnings: ``` core\image.cpp(999): warning C4804: '>': unsafe use of type 'bool' in operation core\io\compression.cpp(178): warning C4334: '<<': result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?) editor\doc\doc_dump.cpp(226): warning C4334: '<<': result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?) scene/resources/material.h(289): warning C4334: '<<': result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?) scene/resources/material.h(298): warning C4334: '<<': result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?) editor\editor_themes.cpp(379): warning C4805: '==': unsafe mix of type 'int' and type 'bool' in operation ``` --- SConstruct | 4 ++-- core/image.cpp | 33 +++++++++++++++++++-------------- core/io/compression.cpp | 2 +- editor/doc/doc_dump.cpp | 2 +- editor/editor_themes.cpp | 2 +- scene/resources/material.h | 4 ++-- 6 files changed, 26 insertions(+), 21 deletions(-) diff --git a/SConstruct b/SConstruct index 1898e0b5d3b..f1587e02803 100644 --- a/SConstruct +++ b/SConstruct @@ -322,13 +322,13 @@ if selected_platform in platform_list: print("WARNING: warnings=yes is deprecated;
