1 ## If the e_shoff field is set to a value either past the end of the file, or
2 ## such that e_shoff + e_shnum * sizeof(Elf_Shdr) is past the end of the file,
3 ## we should emit an error. This test checks that the emitted error is sensible.
5 # RUN: yaml2obj %s -o %t.o
8 ## Sanity check that the section header table is at offset 64:
9 # RUN: llvm-readobj --file-headers %t.o | FileCheck %s --check-prefix=VALIDATE
10 # VALIDATE: SectionHeaderOffset: 0x80{{$}}
12 ## Truncate the file to end before the section header table ends.
13 # RUN: %python -c "with open('%/t.o', 'r+b') as input: input.truncate(0x7f)"
14 # RUN: not llvm-objcopy %t.o 2>&1 | FileCheck %s -DINPUT=%t.o --check-prefix=CASE1
16 # CASE1: error: '[[INPUT]]': section header table goes past the end of the file: e_shoff = 0x80
18 ## Set the e_shoff field to a value much larger than the object file size.
19 # RUN: %python -c "with open('%/t2.o', 'r+b') as input: import struct; bytes = struct.pack('<Q', 0x40000000); input.seek(40); input.write(bytes)"
20 # RUN: not llvm-objcopy %t2.o 2>&1 | FileCheck %s -DINPUT=%t2.o --check-prefix=CASE2
33 # CASE2: error: '[[INPUT]]': section header table goes past the end of the file: e_shoff = 0x40000000
