1# This test is checking to ensure that if a section is removed in the presence 2# of a segment that the segment maintains its shape and properties and that any 3# section inside that segment maintains the relative positioning it had in the 4# segment. Note worthy is that .text3 keeps its offset despite it being 5# possible to place it after .text when .text2 is removed. 6 7# RUN: yaml2obj %s -o %t 8# RUN: llvm-objcopy -R .text2 %t %t2 9# RUN: llvm-readobj -file-headers -program-headers -sections %t2 | FileCheck %s 10# RUN: od -t x1 -j 8192 %t2 | FileCheck %s --check-prefix=DATA 11 12!ELF 13FileHeader: 14 Class: ELFCLASS64 15 Data: ELFDATA2LSB 16 Type: ET_EXEC 17 Machine: EM_X86_64 18Sections: 19 - Name: .text 20 Type: SHT_PROGBITS 21 Flags: [ SHF_ALLOC, SHF_EXECINSTR ] 22 Address: 0x1000 23 AddressAlign: 0x1000 24 Size: 4096 25 - Name: .text2 26 Type: SHT_PROGBITS 27 Flags: [ SHF_ALLOC, SHF_EXECINSTR ] 28 Address: 0x2000 29 AddressAlign: 0x1000 30 Size: 4096 31 Content: "DEADBEEF" 32 - Name: .text3 33 Type: SHT_PROGBITS 34 Flags: [ SHF_ALLOC, SHF_EXECINSTR ] 35 Address: 0x3000 36 AddressAlign: 0x1000 37 Size: 4096 38ProgramHeaders: 39 - Type: PT_LOAD 40 Flags: [ PF_X, PF_R ] 41 Sections: 42 - Section: .text 43 - Section: .text2 44 - Section: .text3 45 46# Make sure that when we remove a section we overwrite it with zeros 47# DATA: 0020000 00 00 00 00 48 49#CHECK: SectionHeaderCount: 6 50 51# CHECK: Sections [ 52# CHECK: Section { 53# CHECK-NEXT: Index: 0 54# CHECK-NEXT: Name: (0) 55# CHECK-NEXT: Type: SHT_NULL (0x0) 56# CHECK-NEXT: Flags [ (0x0) 57# CHECK-NEXT: ] 58# CHECK-NEXT: Address: 0x0 59# CHECK-NEXT: Offset: 60# CHECK-NEXT: Size: 61# CHECK-NEXT: Link: 0 62# CHECK-NEXT: Info: 0 63# CHECK-NEXT: AddressAlignment: 0 64# CHECK-NEXT: EntrySize: 0 65# CHECK-NEXT: } 66# CHECK-NEXT: Section { 67# CHECK-NEXT: Index: 1 68# CHECK-NEXT: Name: .text 69# CHECK-NEXT: Type: SHT_PROGBITS 70# CHECK-NEXT: Flags [ 71# CHECK-NEXT: SHF_ALLOC 72# CHECK-NEXT: SHF_EXECINSTR 73# CHECK-NEXT: ] 74# CHECK-NEXT: Address: 0x1000 75# CHECK-NEXT: Offset: 0x1000 76# CHECK-NEXT: Size: 77# CHECK-NEXT: Link: 0 78# CHECK-NEXT: Info: 0 79# CHECK-NEXT: AddressAlignment: 4096 80# CHECK-NEXT: EntrySize: 0 81# CHECK-NEXT: } 82# CHECK-NEXT: Section { 83# CHECK-NEXT: Index: 2 84# CHECK-NEXT: Name: .text3 85# CHECK-NEXT: Type: SHT_PROGBITS (0x1) 86# CHECK-NEXT: Flags [ 87# CHECK-NEXT: SHF_ALLOC 88# CHECK-NEXT: SHF_EXECINSTR 89# CHECK-NEXT: ] 90# CHECK-NEXT: Address: 0x3000 91# CHECK-NEXT: Offset: 0x3000 92# CHECK-NEXT: Size: 93# CHECK-NEXT: Link: 0 94# CHECK-NEXT: Info: 0 95# CHECK-NEXT: AddressAlignment: 4096 96# CHECK-NEXT: EntrySize: 0 97# CHECK-NEXT: } 98# CHECK-NEXT: Section { 99# CHECK-NEXT: Index: 3 100# CHECK-NEXT: Name: .symtab 101# CHECK-NEXT: Type: SHT_SYMTAB (0x2) 102# CHECK-NEXT: Flags [ (0x0) 103# CHECK-NEXT: ] 104# CHECK-NEXT: Address: 0x0 105# CHECK-NEXT: Offset: 106# CHECK-NEXT: Size: 107# CHECK-NEXT: Link: 4 108# CHECK-NEXT: Info: 1 109# CHECK-NEXT: AddressAlignment: 8 110# CHECK-NEXT: EntrySize: 24 111# CHECK-NEXT: } 112# CHECK-NEXT: Section { 113# CHECK-NEXT: Index: 4 114# CHECK-NEXT: Name: .strtab 115# CHECK-NEXT: Type: SHT_STRTAB (0x3) 116# CHECK-NEXT: Flags [ (0x0) 117# CHECK-NEXT: ] 118# CHECK-NEXT: Address: 0x0 119# CHECK-NEXT: Offset: 120# CHECK-NEXT: Size: 121# CHECK-NEXT: Link: 0 122# CHECK-NEXT: Info: 0 123# CHECK-NEXT: AddressAlignment: 1 124# CHECK-NEXT: EntrySize: 0 125# CHECK-NEXT: } 126# CHECK-NEXT: Section { 127# CHECK-NEXT: Index: 5 128# CHECK-NEXT: Name: .shstrtab 129# CHECK-NEXT: Type: SHT_STRTAB (0x3) 130# CHECK-NEXT: Flags [ (0x0) 131# CHECK-NEXT: ] 132# CHECK-NEXT: Address: 0x0 133# CHECK-NEXT: Offset: 134# CHECK-NEXT: Size: 135# CHECK-NEXT: Link: 0 136# CHECK-NEXT: Info: 0 137# CHECK-NEXT: AddressAlignment: 1 138# CHECK-NEXT: EntrySize: 0 139# CHECK-NEXT: } 140# CHECK-NEXT: ] 141 142#CHECK: ProgramHeaders [ 143#CHECK-NEXT: ProgramHeader { 144#CHECK-NEXT: Type: PT_LOAD (0x1) 145#CHECK-NEXT: Offset: 0x1000 146#CHECK-NEXT: VirtualAddress: 0x0 147#CHECK-NEXT: PhysicalAddress: 0x0 148#CHECK-NEXT: FileSize: 12288 149#CHECK-NEXT: MemSize: 12288 150#CHECK-NEXT: Flags [ (0x5) 151#CHECK-NEXT: PF_R (0x4) 152#CHECK-NEXT: PF_X (0x1) 153#CHECK-NEXT: ] 154#CHECK-NEXT: Alignment: 4096 155#CHECK-NEXT: } 156#CHECK-NEXT:] 157
