JIT Compilation

class RoadRunner.Compiler: The Compiler object provides information about the JIT compiler currently in use.

Compiler.getCompiler()

gets the name of the JIT compiler, i.e. “LLVM” means we are using the LLVM JIT compiler.

Return type:: str

Compiler.getVersion()

get the version of the JIT compiler.

Return type:: str

Compiler.getDefaultTargetTriple()

Return the default target triple the compiler has been configured to produce code for. A ‘triple’ is just a string that contains three items, it is called ‘triple’ as that is a LLVM historical convention.

The target triple is a string in the format of: CPU_TYPE-VENDOR-OPERATING_SYSTEM

or

CPU_TYPE-VENDOR-KERNEL-OPERATING_SYSTEM

Return type:: str

Compiler.getProcessTriple()

Return an appropriate target triple for generating code to be loaded into the current process, e.g. when using the JIT.

Return type:: str

Compiler.getHostCPUName()

getHostCPUName - Get the LLVM name for the host CPU. The particular format of the name is target dependent, and suitable for passing as -mcpu to the target which matches the host.

return - The host CPU name, or empty if the CPU could not be determined.

Return type:: str

Compiler.setCompiler(compiler): A legacy method that currently does not do anything.

Compiler.getCompilerLocation(): A legacy method that currently does not do anything.

Compiler.setCompilerLocation(loc): A legacy method that currently does not do anything.

Compiler.getSupportCodeFolder(): A legacy method that currently does not do anything.

Compiler.setSupportCodeFolder(path): A legacy method that currently does not do anything.
