After parsing and building tree of expression is perform optimization and compiling into x86-32 instructions and returns address of compiled expression. For expressions can by finding derivatives by symbolic or numerical differentiation.

madDisAsm

. The package features a full x86 disassembler including MMX, 3dNow enhanced, SSE and SSE2 support. The disassembler can examine a single x86 instruction see ParseCode or a full function see ParseFunction and either return a short analysis or a full text disassembly. Register contents are watched/followed if possible, this improves the analyses for jump/call targets. Case/switch jump tables are automatically detected and handled correctly.

Tiger

Tiger is a Delphi-hosted compiler infrastructure that lets you generate native x86-64 binaries for Windows and Linux — executables, shared libraries, static libraries, and object files — entirely from code. There is no source language to parse. Instead, you construct programs using a fluent Delphi API: define types, declare functions.

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.
