Beside the initialization work required by the environment and toolchain, crt0 can perform additional operations defined by the programmer, such as executing C++ global constructors and C functions carrying GCC's ((constructor)) attribute. [2] [3] "crt" stands for "C runtime", and the zero stands for "the very beginning".
Windows (Microsoft Visual C++, GCC, Intel C++ Compiler, Delphi), UEFI: RCX/XMM0, RDX/XMM1, R8/XMM2, R9/XMM3: RTL (C) Caller Stack aligned on 16 bytes. 32 bytes shadow space on stack. The specified 8 registers can only be used for parameters 1 through 4. For C++ classes, the hidden this parameter is the first parameter, and is passed in RCX. [31 ...
In C++03 before the introduction of move semantics (in C++11) the special member functions [5] were: Default constructor (if no other constructor is explicitly declared) Copy constructor; Copy assignment operator; Destructor
32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).
In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
Mingw-w64 can generate 32-bit and 64-bit executables for x86 under the target names i686 ... Clang is an exception, as it mostly supports MSVC's C++ ABI on Windows.
Clang has partial C++20 support that can be enabled with the option -std=c++20 (version 10 and later) or -std=c++2a (version 9 and earlier). [ 80 ] EDG started implementing C++20 features in version 5.0 and as of version 6.1 supports most C++20 core language features.
C++ is also more strict in conversions to enums: ints cannot be implicitly converted to enums as in C. Also, enumeration constants (enum enumerators) are always of type int in C, whereas they are distinct types in C++ and may have a size different from that of int. [needs update] In C++ a const variable must be initialized; in C this is not ...
