From 735c47ec3e9a5d64343e764b72c4e35f171b06bb Mon Sep 17 00:00:00 2001 From: Alex Lorenz Date: Mon, 15 Jun 2015 20:30:22 +0000 Subject: MIR Serialization: Connect the machine function analysis pass to the MIR parser. This commit connects the machine function analysis pass (which creates machine functions) to the MIR parser, which will initialize the machine functions with the state from the MIR file and reconstruct the machine IR. This commit introduces a new interface called 'MachineFunctionInitializer', which can be used to provide custom initialization for the machine functions. This commit also introduces a new diagnostic class called 'DiagnosticInfoMIRParser' which is used for MIR parsing errors. This commit modifies the default diagnostic handling in LLVMContext - now the the diagnostics are printed directly into llvm::errs() so that the MIR parsing errors can be printed with colours.
