FasmOnDelphi

FasmOnDelphi is a Free Pascal/Delphi library for using Flat Assembler in any OS (can use FASM.DLL on Windows). It is a cross platform (Flat Assembler can work only on i386 compatible platforms) library for using FASM in runtime. In contrast to Fasm4Delphi, it does not depend on operating system and bit type.

Ganymede

Ganymede is a high-performance, embeddable scripting engine designed to compile source code directly into native x64 machine code via Just-In-Time compilation. It eliminates the need for virtual machines or interpreters, providing a flat C-style API for seamless integration with C++ and Delphi applications.

MathParser

An expression parser and a virtual machine. A formula is compiled to a flat byte array and evaluated by a linear pass over it, with no allocation on the path of an ordinary formula. On x86-64 an optional accelerator compiles that bytecode to machine code and hands anything it declines back to the interpreter, so an answer is never fast but wrong. Results are cached by shape: once 2 + 3 has been compiled, 5 + 7 reuses the same script and only writes the numbers into a copy. 163 functions to call and 249 names in the table, your own functions and variables bound by address, symbolic differentiation. The Lazarus parser packages require FCL and define NOFORMS and NOGRAPHICS, so they install without LCL. WebAssembly uses a separate console configuration. Two units ask for more at their defaults, Thread through Application.HandleException and BlobManager through TGraphic; drop the defines and add the LCL to the package if you want them.
