Over time, the PE format has grown with the Windows platform. Notable extensions include the .NET PE format for managed code, PE32+ for 64-bit address space support, and a specialized version for Windows CE. To determine whether a PE file is intended for 32-bit or 64-bit architectures, one can examine the Machine field in the IMAGE_FILE_HEADER. [6]
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 ...
The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
The resulting implementation of the IA-64 64-bit architecture was the Itanium, finally introduced in June 2001. The Itanium's performance running legacy x86 code did not meet expectations, and it failed to compete effectively with x86-64 , which was AMD's 64-bit extension of the 32-bit x86 architecture (Intel uses the name Intel 64 , previously ...
A 2021 study suggested that WebAssembly, in the versions they tested at that time, was well faster than JavaScript in certain cases and browsers only, such as running a complex function on a small file, e.g. processing a graphics file, but that JavaScript had some optimizations available, e.g. JIT, that WebAssembly did not.

64-bit and 32-bit applications, C, C++, .NET, and dlls generated by any language compiler. Performance and memory profiler that identifies time-intensive functions and detects memory leaks and errors. Proprietary gprof: Linux/Unix Any language supported by gcc: Several tools with combined sampling and call-graph profiling.
Since its inception, Firefox for Linux supported the 32-bit memory architecture of the IA-32 instruction set. 64-bit builds were introduced in the 4.0 release. [185] The 46.0 release replaced GTK 2.18 with 3.4 as a system requirement on Linux and other systems running X.Org. [197] Starting with 53.0, the 32-bit builds require the SSE2 ...
