From 5098da0a7e3fb841f71bf5be9211b36fa95f140f Mon Sep 17 00:00:00 2001 From: Devang Patel Date: Mon, 26 Apr 2010 22:54:28 +0000 Subject: [PATCH] Use DW_AT_entry_pc instead of DW_AT_low_pc/DW_AT_high_pc pair. This simplifies debug range entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102394 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/DwarfDebug.cpp | 6 +++--- .../{2010-03-22-CU-HighLow.ll => 2010-04-25-CU-entry_pc.ll} | 2 +- 2 files changed, 4 insertions(+), 4 deletions(-) rename test/DebugInfo/{2010-03-22-CU-HighLow.ll => 2010-04-25-CU-entry_pc.ll} (94%) diff --git a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp index c31aec17590..3ce0711a520 100644 --- a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp +++ b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp @@ -1734,9 +1734,9 @@ void DwarfDebug::constructCompileUnit(MDNode *N) { addUInt(Die, dwarf::DW_AT_language, dwarf::DW_FORM_data1, DIUnit.getLanguage()); addString(Die, dwarf::DW_AT_name, dwarf::DW_FORM_string, FN); - addLabel(Die, dwarf::DW_AT_low_pc, dwarf::DW_FORM_addr, TextSectionSym); - addLabel(Die, dwarf::DW_AT_high_pc, dwarf::DW_FORM_addr, - Asm->GetTempSymbol("text_end")); + // Use DW_AT_entry_pc instead of DW_AT_low_pc/DW_AT_high_pc pair.
