FunctionCompileExportString
FunctionCompileExportString[fspec]
gives a string of textual LLVM code obtained by compiling the function specification fspec.
FunctionCompileExportString[defs,fspec]
uses the auxiliary definitions defs for compilation.
FunctionCompileExportString[fspec,"format"]
gives a string of textual code in the specified format.
Details and Options

- Functions can be given as a Function pure function, a list of pure functions or an association of pure functions.
- Auxiliary definitions can be given with FunctionDeclaration or by giving a CompilerEnvironment option.
- Possible values for "format" include:
-
"LLVM" LLVM intermediate code "Assembler" assembler for a specific architecture - The following options can be given:
-
CompilerEnvironment Automatic an environment of definitions for compilation CompilerOptions Automatic detailed options for the compilation pipeline TargetSystem Automatic $SystemID for the target architecture - With the setting TargetSystem->Automatic, FunctionCompileExportString will generate code for the machine architecture on which it is being run, including, for example, taking account of word length.
- In FunctionCompileExportString[func,…], func can be a CompiledCodeFunction object.

Generate a compiled version of a function and return the resulting LLVM IR as a string:
The export format can be given explicitly:
Several functions can be compiled with FunctionCompileExportString:
It can be useful to use an association to hold the functions:
Auxiliary definitions can be given with FunctionDeclaration:
Options (2)
CompilerEnvironment (1)
TargetSystem (1)
The default setting of Automatic generates code for the machine architecture on which it is being run:
TargetSystem can be set to the $SystemID of the desired platform:
TargetSystem can be combined with different format settings:
TargetSystem can be set for architectures for which the Wolfram Engine does not exist:
