The Swift community maintains a version which adds support for the language. Free Pascal and the Lazarus IDE can use LLDB as backend for their own FpDebug engine. The LLDB debugger is known to work on macOS, Linux, FreeBSD, NetBSD and Windows, [4] and supports i386, x86-64, and ARM instruction sets. [5] LLDB is the default debugger for Xcode 5 ...
The Intel 386, originally released as the 80386 and later renamed i386, was the first x86 32-bit microprocessor designed by Intel. Pre-production samples of the 386 were released to select developers in 1985, while mass production commenced in 1986.
The IA-32 architecture defines a 48-bit segmented address format, with a 16-bit segment number and a 32-bit offset within the segment. Segmented addresses are mapped to 32-bit linear addresses. Demand paging 32-bit linear addresses are virtual addresses rather than physical addresses; they are translated to physical addresses through a page table.
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 known as AMD64). Original 8086/8088 instructions
The Embeddable Linux Kernel Subset (ELKS), formerly known as Linux-8086, is a Linux-like operating system kernel.It is a subset of the Linux kernel, intended for 16-bit computers with limited processor and memory resources such as machines powered by Intel 8086 and compatible microprocessors not supported by 32-bit Linux.
MIT's Operating System Engineering course formerly used the original V6 source code. xv6 was created as a modern replacement, because PDP-11 machines are not widely available and the original operating system was written in archaic pre-ANSI C.
GNU Hurd is a collection of microkernel servers written as part of GNU, for the GNU Mach microkernel. It has been under development since 1990 by the GNU Project of the Free Software Foundation, designed as a replacement for the Unix kernel, [4] and released as free software under the GNU General Public License.
In the mid-1990s, a facility for supplying new microcode was initially referred to as the Pentium Pro BIOS Update Feature. [18] [19] It was intended that user-mode applications should make a BIOS interrupt call to supply a new "BIOS Update Data Block", which the BIOS would partially validate and save to nonvolatile BIOS memory; this could be supplied to the installed processors on next boot.
