From 829b1700484d145ca93750384e7f49ef61a8d9b4 Mon Sep 17 00:00:00 2001 From: Diego Novillo Date: Wed, 16 Apr 2014 16:54:24 +0000 Subject: Add support for optimization reports. Summary: This patch adds a new flag -Rpass=. The flag indicates the name of the optimization pass that should emit remarks stating when it made a transformation to the code. This implements the design I proposed in: https://docs.google.com/document/d/1FYUatSjZZO-zmFBxjOiuOzAy9mhHA8hqdvklZv68WuQ/edit?usp=sharing Other changes: - Add DiagnosticIDs::isRemark(). Use it in printDiagnosticOptions to print "-R" instead of "-W" in the diagnostic message. - In BackendConsumer::OptimizationRemarkHandler, get a SourceLocation object out of the file name, line and column number. Use that location in the call to Diags.Report(). - When -Rpass is used without debug info a note is emitted alerting the user that they need to use -gline-tables-only -gcolumn-info to get this information.
