From 20fff32b7d1f1a1bd417b22aa9f26ededd97a3e5 Mon Sep 17 00:00:00 2001 From: Francis Visoiu Mistrih Date: Tue, 12 Mar 2019 20:28:50 +0000 Subject: [Remarks] Add -foptimization-record-passes to filter remark emission Currently we have -Rpass for filtering the remarks that are displayed as diagnostics, but when using -fsave-optimization-record, there is no way to filter the remarks while generating them. This adds support for filtering remarks by passes using a regex. Ex: `clang -fsave-optimization-record -foptimization-record-passes=inline` will only emit the remarks coming from the pass `inline`. This adds: * `-fsave-optimization-record` to the driver * `-opt-record-passes` to cc1 * `-lto-pass-remarks-filter` to the LTOCodeGenerator * `--opt-remarks-passes` to lld * `-pass-remarks-filter` to llc, opt, llvm-lto, llvm-lto2 * `-opt-remarks-passes` to gold-plugin Differential Revision: https://reviews.llvm.org/D59268 llvm-svn: 355964 --- clang/lib/Frontend/CompilerInvocation.cpp | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'clang/lib/Frontend/CompilerInvocation.cpp') diff --git a/clang/lib/Frontend/CompilerInvocation.cpp b/clang/lib/Frontend/CompilerInvocation.cpp index 1cd1cb1..b5872b9 100644 --- a/clang/lib/Frontend/CompilerInvocation.cpp +++ b/clang/lib/Frontend/CompilerInvocation.cpp @@ -1218,6 +1218,11 @@ static bool ParseCodeGenArgs(CodeGenOptions &Opts, ArgList &Args, InputKind IK, if (!Opts.OptRecordFile.empty()) NeedLocTracking = true; + if (Arg *A = Args.getLastArg(OPT_opt_record_passes)) { + Opts.OptRecordPasses = A->getValue(); + NeedLocTracking = true; + } + if (Arg *A = Args.getLastArg(OPT_Rpass_EQ)) { Opts.OptimizationRemarkPattern = GenerateOptimizationRemarkRegex(Diags, Args, A); -- cgit v1.1
