Detailed Description

Owns LLVM process initialization and an in-process tool registry.

A long-lived host constructs one session and uses it for every embedded tool invocation. The individual tools borrow a ToolContext and therefore do not initialize or shut down LLVM themselves.

LLVM tools may use process-global state. Tool invocations must be externally serialized; concurrent calls are not supported.

Member Function Documentation

◆ callTool()

ErrorOr< int > ToolSession::callTool ( ArrayRef< const char * > Args )

Invokes the tool named by Args[0].

Args may instead contain a process-style argv beginning with the session executable or an LLVM multicall name.
