From 6d0903f4a09fcda8ebe3af29b44cb3df2a4663c2 Mon Sep 17 00:00:00 2001 From: Kai Nacke Date: Tue, 4 Feb 2014 06:07:00 +0000 Subject: Revert: ARM: Enable use of relocation type tlsldo in debug info for tls data. There seems to be a new problem with the debug info in the test case. I'll have to investigate this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200737 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/ARM/ARMTargetObjectFile.cpp | 6 ------ lib/Target/ARM/ARMTargetObjectFile.h | 3 --- test/DebugInfo/ARM/tls.ll | 26 -------------------------- 3 files changed, 35 deletions(-) delete mode 100644 test/DebugInfo/ARM/tls.ll diff --git a/lib/Target/ARM/ARMTargetObjectFile.cpp b/lib/Target/ARM/ARMTargetObjectFile.cpp index e6b8cce091..1c5dc51e7f 100644 --- a/lib/Target/ARM/ARMTargetObjectFile.cpp +++ b/lib/Target/ARM/ARMTargetObjectFile.cpp @@ -51,9 +51,3 @@ getTTypeGlobalReference(const GlobalValue *GV, Mangler *Mang, MCSymbolRefExpr::VK_ARM_TARGET2, getContext()); } - -const MCExpr *ARMElfTargetObjectFile:: -getDebugThreadLocalSymbol(const MCSymbol *Sym) const { - return MCSymbolRefExpr::Create(Sym, MCSymbolRefExpr::VK_ARM_TLSLDO, - getContext()); -} diff --git a/lib/Target/ARM/ARMTargetObjectFile.h b/lib/Target/ARM/ARMTargetObjectFile.h index cb86896c03..7f60727e53 100644 --- a/lib/Target/ARM/ARMTargetObjectFile.h +++ b/lib/Target/ARM/ARMTargetObjectFile.h @@ -36,9 +36,6 @@ public: virtual const MCSection *getAttributesSection() const { return AttributesSection; } - - /// \brief Describe a TLS variable address within debug info. - virtual const MCExpr *getDebugThreadLocalSymbol(const MCSymbol *Sym) const; }; } // end namespace llvm diff --git a/test/DebugInfo/ARM/tls.ll b/test/DebugInfo/ARM/tls.ll deleted file mode 100644 index 1a613d2e3f..0000000000 --- a/test/DebugInfo/ARM/tls.ll +++ /dev/null @@ -1,26 +0,0 @@ -; RUN: llc -O0 -filetype=asm -mtriple=armv7-linux-gnuehabi < %s | FileCheck %s -; -; Generated with clang with source -; __thread int x; - -@x = thread_local global i32 0, align 4 - -!llvm.dbg.cu = !{!0} -!llvm.module.flags = !{!7, !8} - -; 6 byte of data -; CHECK: .byte 6 @ DW_AT_location -; DW_OP_const4u -; CHECK: .byte 12 -; The debug relocation of the address of the tls variable -; CHECK: .long x(tlsldo) - -!0 = metadata !{i32 786449, metadata !1, i32 12, metadata !"clang version 3.5 ", i1 false, metadata !"", i32 0, metadata !2, metadata !2, metadata !2, metadata !3, metadata !2, metadata !""} ; [ DW_TAG_compile_unit ] [/tmp/arm.c] [DW_LANG_C99] -!1 = metadata !{metadata !"arm.c", metadata !"/tmp"} -!2 = metadata !{i32 0} -!3 = metadata !{metadata !4} -!4 = metadata !{i32 786484, i32 0, null, metadata !"x", metadata !"x", metadata !"", metadata !5, i32 1, metadata !6, i32 0, i32 1, i32* @x, null} ; [ DW_TAG_variable ] [x] [line 1] [def] -!5 = metadata !{i32 786473, metadata !1} ; [ DW_TAG_file_type ] [/tmp/arm.c] -!6 = metadata !{i32 786468, null, null, metadata !"int", i32 0, i64 32, i64 32, i64 0, i32 0, i32 5} ; [ DW_TAG_base_type ] [int] [line 0, size 32, align 32, offset 0, enc DW_ATE_signed] -!7 = metadata !{i32 2, metadata !"Dwarf Version", i32 4} -!8 = metadata !{i32 1, metadata !"Debug Info Version", i32 1} -- cgit v1.2.3
