From e82ada6983858183ac591f7147b685e5bf16995b Mon Sep 17 00:00:00 2001 From: Kevin Enderby Date: Wed, 16 Jan 2013 17:46:23 +0000 Subject: We want the dwarf AT_producer for assembly source files to match clang's AT_producer. Which includes clang's version information so we can tell which version of the compiler was used. This is the first of two steps to allow us to do that. This is the llvm-mc change to provide a method to set the AT_producer string. The second step, coming soon to a clang near you, will have the clang driver pass the value of getClangFullVersion() via an flag when invoking the integrated assembler on assembly source files. rdar://12955296 llvm-svn: 172630 --- llvm/lib/MC/MCDwarf.cpp | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) (limited to 'llvm/lib/MC/MCDwarf.cpp') diff --git a/llvm/lib/MC/MCDwarf.cpp b/llvm/lib/MC/MCDwarf.cpp index 5691822e8e1..74851ce140a 100644 --- a/llvm/lib/MC/MCDwarf.cpp +++ b/llvm/lib/MC/MCDwarf.cpp @@ -638,9 +638,15 @@ static void EmitGenDwarfInfo(MCStreamer *MCOS, } // AT_producer, the version of the assembler tool. - MCOS->EmitBytes(StringRef("llvm-mc (based on LLVM ")); - MCOS->EmitBytes(StringRef(PACKAGE_VERSION)); - MCOS->EmitBytes(StringRef(")")); + StringRef DwarfDebugProducer = context.getDwarfDebugProducer(); + if (!DwarfDebugProducer.empty()){ + MCOS->EmitBytes(DwarfDebugProducer); + } + else { + MCOS->EmitBytes(StringRef("llvm-mc (based on LLVM ")); + MCOS->EmitBytes(StringRef(PACKAGE_VERSION)); + MCOS->EmitBytes(StringRef(")")); + } MCOS->EmitIntValue(0, 1); // NULL byte to terminate the string. // AT_language, a 4 byte value.
