I can't find enough information to decide which compiler should I use to compile my project. There are several programs on different computers simulating a process. On Linux, I'm using GCC. Everything is great. I can optimize code, it compiles fast and uses not-so-much memory.
I do my own benchmark with MSVC and GCC compilers. Later one produces slightly faster binaries (for each subarchitecture). Though compile time is much more than MSVC.
So I decided to use MinGW. But can't find any explanation about exception handling methods and their implementations in MinGW. I can use different distributions for different operating systems and architectures.
SJLJ (setjmp/longjmp): – available for 32 bit and 64 bit – not “zero-cost”: even if an exception isn’t thrown, it incurs a minor performance penalty (~15% in exception heavy code) – allows exceptions to traverse through e.g. windows callbacks
DWARF (DW2, dwarf-2) – available for 32 bit only – no permanent runtime overhead – needs whole call stack to be dwarf-enabled, which means exceptions cannot be thrown over e.g. Windows system DLLs.
SEH (zero overhead exception) – will be available for 64-bit GCC 4.8.
