llvm/llvm/test/tools/llvm-objcopy/ELF/invalid-e_shoff.test

## If the e_shoff field is set to a value either past the end of the file, or
## such that e_shoff + e_shnum * sizeof(Elf_Shdr) is past the end of the file,
## we should emit an error. This test checks that the emitted error is sensible.

# RUN: yaml2obj %s -o %t.o
# RUN: cp %t.o %t2.o

## Validate that the section header table is at offset 64:
# RUN: llvm-readobj --file-headers %t.o | FileCheck %s --check-prefix=VALIDATE
# VALIDATE: SectionHeaderOffset: 0x80{{$}}

## Truncate the file to end before the section header table ends.
# RUN: %python -c "with open('%/t.o', 'r+b') as input: input.truncate(0x7f)"
# RUN: not llvm-objcopy %t.o 2>&1 | FileCheck %s -DINPUT=%t.o --check-prefix=CASE1

# CASE1: error: '[[INPUT]]': section header table goes past the end of the file: e_shoff = 0x80

## Set the e_shoff field to a value much larger than the object file size.
# RUN: %python -c "with open('%/t2.o', 'r+b') as input: import struct; bytes = struct.pack('<Q', 0x40000000); input.seek(40); input.write(bytes)"
# RUN: not llvm-objcopy %t2.o 2>&1 | FileCheck %s -DINPUT=%t2.o --check-prefix=CASE2
