WebEach build type causes CMake to automatically append a set of flags to CFLAGS and CXXFLAGS. When using the common Release build type, it automatically appends the -O3 compiler optimization flag, and this overrides the default Arch Linux flag which currently is -O2 (defined in the makepkg configuration file). This is undesired, as it deviates ... Use compiler documentation to see difference between O2 and O3 and make your choice (: for example - gcc. Here you can found recommendation to use O2 for stability. You can use this macro for removing flags: macro (remove_cxx_flag flag) string (REPLACE "$ {flag}" "" CMAKE_CXX_FLAGS "$ {CMAKE_CXX_FLAGS}") endmacro () [usage]

When using a type that occupies multiple registers, such as long long on a 32-bit system, split the registers apart and allocate them independently.
