From 4a867c7a05bd0560cc16b3c16286e1c76073334e Mon Sep 17 00:00:00 2001 From: Daniel Sanders Date: Mon, 15 Jun 2015 09:19:41 +0000 Subject: [PATCH] Replace string GNU Triples with llvm::Triple in InitMCObjectFileInfo. NFC. Summary: This affects other tools so the previous C++ API has been retained as a deprecated function for the moment. Clang has been updated with a trivial patch (not covered by the pre-commit review) to avoid breaking -Werror builds. Other in-tree tools will be fixed with similar trivial patches. This continues the patch series to eliminate StringRef forms of GNU triples from the internals of LLVM that began in r239036.
