1# REQUIRES: x86-registered-target2 3## It is possible for the section header table and symbol table to share the4## same string table for storing section and symbol names. This test shows that5## under various circumstances, the names are still correct after llvm-objcopy6## has copied such an object file, and that the name table is still shared.7## This test uses the assembler rather than yaml2obj because yaml2obj generates8## separate string tables, whereas the assembler shares them.9 10# RUN: llvm-mc -filetype=obj -triple x86_64-pc-linux %s -o %t.o11## Verify check that the string tables are shared:12# RUN: llvm-readobj --section-headers %t.o \13# RUN: | FileCheck %s --check-prefix=VALIDATE --implicit-check-not=.shstrtab14 15# VALIDATE: Name: .strtab16 17## Case 1: basic copy.18# RUN: llvm-objcopy %t.o %t.basic19# RUN: llvm-readobj --section-headers --symbols %t.basic \20# RUN: | FileCheck %s --check-prefix=BASIC --implicit-check-not=.shstrtab21 22# BASIC: Sections [23# BASIC: Name: .strtab (24# BASIC: Name: .foo (25# BASIC: Symbols [26# BASIC: Name: foo (27 28## Case 2: renaming a section.29# RUN: llvm-objcopy %t.o %t.rename-section --rename-section .foo=.oof30# RUN: llvm-readobj --section-headers --symbols %t.rename-section \31# RUN: | FileCheck %s --check-prefix=SECTION-RENAME --implicit-check-not=.shstrtab32 33# SECTION-RENAME: Sections [34# SECTION-RENAME: Name: .strtab (35# SECTION-RENAME: Name: .oof (36# SECTION-RENAME: Symbols [37# SECTION-RENAME: Name: foo (38 39## Case 3: renaming a symbol.40# RUN: llvm-objcopy %t.o %t.redefine-symbol --redefine-sym foo=oof41# RUN: llvm-readobj --section-headers --symbols %t.redefine-symbol \42# RUN: | FileCheck %s --check-prefix=SYMBOL-RENAME --implicit-check-not=.shstrtab43 44# SYMBOL-RENAME: Sections [45# SYMBOL-RENAME: Name: .strtab (46# SYMBOL-RENAME: Name: .foo (47# SYMBOL-RENAME: Symbols [48# SYMBOL-RENAME: Name: oof (49 50## Case 4: removing a section.51# RUN: llvm-objcopy %t.o %t.remove-section -R .foo52# RUN: llvm-readobj --section-headers --symbols %t.remove-section \53# RUN: | FileCheck %s --check-prefix=SECTION-REMOVE --implicit-check-not=.shstrtab --implicit-check-not=.foo54 55# SECTION-REMOVE: Sections [56# SECTION-REMOVE: Name: .strtab (57# SECTION-REMOVE: Symbols [58# SECTION-REMOVE: Name: foo (59 60## Case 5: removing a symbol.61# RUN: llvm-objcopy %t.o %t.remove-symbol -N foo62# RUN: llvm-readobj --section-headers --symbols %t.remove-symbol \63# RUN: | FileCheck %s --check-prefix=SYMBOL-REMOVE --implicit-check-not=.shstrtab --implicit-check-not="Name: foo"64 65# SYMBOL-REMOVE: Sections [66# SYMBOL-REMOVE: Name: .strtab (67# SYMBOL-REMOVE: Name: .foo (68# SYMBOL-REMOVE: Symbols [69 70## Case 6: adding a section.71# RUN: llvm-objcopy %t.o %t.add-section --add-section .bar=%s72# RUN: llvm-readobj --section-headers --symbols %t.add-section \73# RUN: | FileCheck %s --check-prefix=SECTION-ADD --implicit-check-not=.shstrtab74 75# SECTION-ADD: Sections [76# SECTION-ADD: Name: .strtab (77# SECTION-ADD: Name: .foo (78# SECTION-ADD: Name: .bar (79# SECTION-ADD: Symbols [80# SECTION-ADD: Name: foo (81 82## Case 7: adding a symbol.83# RUN: llvm-objcopy %t.o %t.add-symbol --add-symbol bar=0x123484# RUN: llvm-readobj --section-headers --symbols %t.add-symbol \85# RUN: | FileCheck %s --check-prefix=SYMBOL-ADD --implicit-check-not=.shstrtab86 87# SYMBOL-ADD: Sections [88# SYMBOL-ADD: Name: .strtab (89# SYMBOL-ADD: Name: .foo (90# SYMBOL-ADD: Symbols [91# SYMBOL-ADD: Name: foo (92# SYMBOL-ADD: Name: bar (93 94## Case 8: removing all symbols.95# RUN: llvm-objcopy %t.o %t.strip-all --strip-all96# RUN: llvm-readobj --section-headers --symbols %t.strip-all \97# RUN: | FileCheck %s --check-prefix=STRIP-ALL --implicit-check-not=.shstrtab98 99# STRIP-ALL: Sections [100# STRIP-ALL: Name: .strtab (101# STRIP-ALL: Name: .foo (102# STRIP-ALL: Symbols [103# STRIP-ALL-NEXT: ]104 105.section .foo,"a",@progbits106foo = 0x4321107
