Flat Assembler is a fast and efficient self-assembling 80x86 assembler. It supports x86 and x86-64 instruction sets with MMX, 3DNow!, SSE up to SSE4, AVX, AVX2, and XOP extensions. It can produce output in binary, MZ, PE, COFF, or ELF format. It includes powerful but easy-to-use macroinstruction support and does multiple passes to optimize the instruction codes for size. It is written entirely in assembly language.
An almost ISO C compatible C compiler that produces binaries for 6502-based computers. Targets that are supported out of the box are: Apple ][, Atari 8-bit machines, Commodore C64/C128/C16/C116, Commodore Plus/4, Commodore 600/700, GEOS for C64, and Lynx. The package includes a complete suite of assembler development tools (assembler, linker, archiver) which allows mixing of C and assembler code.
The Amsterdam Compiler Kit is a fully-featured retargetable compiler toolchain. It will cross-compile ANSI C, K&R C, Pascal, Modula-2, Occam, Fortran and Basic for a number of architectures including, but not limited to, the 6500, 68000, Z80, i80, i86, i386, and PDP-11. It provides a complete development environment including preprocessors, compilers, assemblers, linkers, librarian tools, and target download tools.
Linux Debug is a functional clone of the old DOS debug.com for x86 linux. Functions include the ability to alter/examine memory and registers, set/clear breakpoints, step into and trace over, symmetric symbolic disassembler, and symbolic assembler. It has a simplified UI, and can work with bin and elf format files. Symbolic functions work only if debug symbols available in the file header. It features a NASM-compatible syntax for both disassembler and single line assembler.
Yasm is a complete rewrite of the NASM assembler. It currently supports the x86 and AMD64 instruction sets, accepts NASM and GAS assembler syntaxes, outputs binary, ELF32, ELF64, COFF, Mach-O (32 and 64), RDOFF2, Win32, and Win64 object formats, and generates source debugging information in STABS, DWARF 2, and CodeView 8 formats.
nescom is a suite of assembler and linker tools for the CPU used in the NES/Famicom. It can produce xa65-compatible relocatable object files, IPS format patches, raw binary images, and ROM images in INES format. nescom is a sister project of snescom, and shares much of the syntax and features.
TinyaML is a virtual machine, a compiler, and a compiler- compiler, powered by the abstract parser tinyap. It is endian-safe and allows easy bindings of new C APIs into the virtual machine. The VM executes wordcode with a virtual threading model and features a garbage collector. TinyaML allows the user to compile and run assembly code, or plug new grammars for higher-level languages into the parser and implement the methods to compile their ASTs.
