The primary supported (and best tested) processor families are 64- and 32-bit ARM, 64- and 32-bit x86 64 and x86 and 64-bit PowerPC and SPARC. [77] GCC target processor families as of version 11.1 include: [78]
It is able to build 32-bit or 64-bit binaries, for any version of Windows since Windows 98. TDM-GCC is a redistribution of components that are freely available elsewhere. [3] A large difference is that it changes the default GCC libraries to be statically linked, and use a shared memory region for exception handling. [2]
Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
Darwin currently includes support for the 64-bit x86-64 variant of the Intel x86 processors used in Intel-based Macs and the 64-bit ARM processors used in the iPhone 5S and later, the 6th generation iPod Touch, the 5th generation iPad and later, the iPad Air family, the iPad Mini 2 and later, the iPad Pro family, the fourth generation and later ...
The Linux kernel is a free and open source, [11]: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
Since FreeBSD 13 the focus has been on x86-64 and aarch64 platforms which have Tier 1 support. [35] IA-32 is a Tier 1 platform in FreeBSD 12 but is a Tier 2 platform in FreeBSD 13. 32 bit ARM processors using armv6 or armv7 also have Tier 2 support. 64 bit versions of PowerPC and RISC-V are also supported.
