<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Zaara Syeda (syzaara) <details> <summary>Changes</summary> Failure with testcase toc-conf.c observed when building with LLVM_REVERSE_ITERATION=ON. Changing from using llvm::StringSet to std::set<llvm:StringRef> to ensure iteration order is deterministic. Note: the functionality of the feature does not require a specific iteration order, however, this will allow testing to be consistent. >From llvm docs: The advantages of std::set are that its iterators are stable (deleting or inserting an element from the set does not affect iterators or pointers to other elements) and that iteration over the set is guaranteed to be in sorted order. --- Full diff: https://github.com/llvm/llvm-project/pull/86840.diff 2 Files Affected: - (modified) clang/lib/Driver/ToolChains/AIX.cpp (+3-3) - (modified) clang/test/Driver/toc-conf.c (+1-1) ``````````diff diff --git a/clang/lib/Driver/ToolChains/AIX.cpp b/clang/lib/Driver/ToolChains/AIX.cpp index 6e089903a3158a..7a62b0f9aec419 100644 --- a/clang/lib/Driver/ToolChains/AIX.cpp +++ b/clang/lib/Driver/ToolChains/AIX.cpp @@ -471,7 +471,7 @@ static void addTocDataOptions(const llvm::opt::ArgList &Args, // the global setting of tocdata in TOCDataGloballyinEffect. // Those that have the opposite setting to TOCDataGloballyinEffect, are added // to ExplicitlySpecifiedGlobals. - llvm::StringSet<> ExplicitlySpecifiedGlobals; + std::set<llvm::StringRef> ExplicitlySpecifiedGlobals; for (const auto Arg : Args.filtered(options::OPT_mtocdata_EQ, options::OPT_mno_tocdata_EQ)) { TOCDataSetting ArgTocDataSetting = @@ -486,7 +486,7 @@ static void addTocDataOptions(const llvm::opt::ArgList &Args, ExplicitlySpecifiedGlobals.erase(Val); } - auto buildExceptionList = [](const llvm::StringSet<> &ExplicitValues, + auto buildExceptionList = [](const std::set<llvm::StringRef> &ExplicitValues, const char *OptionSpelling) { std::string Option(OptionSpelling); bool IsFirst = true; @@ -495,7 +495,7 @@ static void addTocDataOptions(const llvm::opt::ArgList &Args, Option += ","; IsFirst = false; - Option += E.first(); + Option += E.str(); } return Option; }; diff --git a/clang/test/Driver/toc-conf.c b/clang/test/Driver/toc-conf.c index 80d92ee1a90b4b..7b2d5122ebc6ce 100644 --- a/clang/test/Driver/toc-conf.c +++ b/clang/test/Driver/toc-conf.c @@ -23,7 +23,7 @@ void func() { // CHECK-CONF1-NOT: warning: // CHECK-CONF1: "-cc1"{{.*}}" "-mno-tocdata" -// CHECK-CONF1: "-mtocdata=g2,g1" +// CHECK-CONF1: "-mtocdata=g1,g2" // CHECK-CONF2-NOT: warning: // CHECK-CONF2: "-cc1"{{.*}}" "-mtocdata" `````````` </details> https://github.com/llvm/llvm-project/pull/86840 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
