From 0b50cb79ada2f361b11571b56350587012d0f1da Mon Sep 17 00:00:00 2001 From: Richard Smith Date: Wed, 14 Nov 2012 23:55:25 +0000 Subject: Add -cc1 option -fno-diagnostics-use-presumed-location, a handy mode for working with preprocessed testcases. This causes source locations in diagnostics to point at the spelling location instead of the presumed location, while still keeping the semantic effects of the line directives (entering and leaving system-header mode, primarily). llvm-svn: 168004 --- clang/lib/Basic/SourceManager.cpp | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'clang/lib/Basic/SourceManager.cpp') diff --git a/clang/lib/Basic/SourceManager.cpp b/clang/lib/Basic/SourceManager.cpp index cd0284a18e5..a32e41ef533 100644 --- a/clang/lib/Basic/SourceManager.cpp +++ b/clang/lib/Basic/SourceManager.cpp @@ -1361,7 +1361,8 @@ const char *SourceManager::getBufferName(SourceLocation Loc, /// /// Note that a presumed location is always given as the expansion point of an /// expansion location, not at the spelling location. -PresumedLoc SourceManager::getPresumedLoc(SourceLocation Loc) const { +PresumedLoc SourceManager::getPresumedLoc(SourceLocation Loc, + bool UseLineDirectives) const { if (Loc.isInvalid()) return PresumedLoc(); // Presumed locations are always for expansion points. @@ -1395,7 +1396,7 @@ PresumedLoc SourceManager::getPresumedLoc(SourceLocation Loc) const { // If we have #line directives in this file, update and overwrite the physical // location info if appropriate. - if (FI.hasLineDirectives()) { + if (UseLineDirectives && FI.hasLineDirectives()) { assert(LineTable && "Can't have linetable entries without a LineTable!"); // See if there is a #line directive before this.
