These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts. The updated instruction set is grouped according to architecture ( i186 , i286 , i386 , i486 , i586 / i686 ) and is referred to as (32-bit) x86 and (64-bit) x86-64 (also ...
POD return values 33–64 bits in size are returned via the EAX:EDX registers. Non-POD return values or values larger than 64-bits, the calling code will allocate space and passes a pointer to this space via a hidden parameter on the stack. The called function writes the return value to this address. Stack aligned on 4-byte boundary. stdcall ...
The 64-bit version of the x86 architecture, known as x86-64, AMD64, and Intel 64, has two calling sequences in common use. One calling sequence, defined by Microsoft, is used on Windows; the other calling sequence, specified in the AMD64 System V ABI, is used by Unix-like systems and, with some changes, by OpenVMS .

In the C and C++ programming languages, unistd.h is the name of the header file that provides access to the POSIX operating system API. [1] It is defined by the POSIX.1 standard, the base of the Single Unix Specification, and should therefore be available in any POSIX-compliant operating system and compiler.
The term 64-bit also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a word size that defines certain classes of computer architecture, buses, memory, and CPUs and, by extension, the software that runs on them. 64-bit CPUs have been used in supercomputers since the 1970s (Cray-1, 1975) and in reduced ...
As with Cygwin, MSYS2 supports path translation for non-MSYS2 software launched from it. For example one can use the command notepad++ /c/Users/John/file.txt to launch an editor that will open the file with the Windows path C:\Users\John\file.txt. [9] [8] MSYS2 and its bash environment is used by Git and GNU Octave for their official Windows ...
That same day, Linus Torvalds replied with a concern that the use of 32-bit time values in the x32 ABI could cause problems in the future. [11] [12] This is because the use of 32-bit time values would cause the time values to overflow in the year 2038. [11] [12] Following this request, the developers of the x32 ABI changed the time values to 64 ...
