# If the offset and/or size fields of the PT_DYNAMIC field become corrupted,
|
|
# we should report a sensible error message.
|
|
|
|
# Creating such a malformed file is hard. The easiest way to simulate it is to
|
|
# truncate the file. Note that the section headers must first be stripped or
|
|
# llvm-readobj will fail to parse the file due to the section header table
|
|
# offset pointing outside the file.
|
|
|
|
# RUN: yaml2obj %s -o %t.base
|
|
# RUN: llvm-objcopy --strip-sections %t.base %t.stripped
|
|
|
|
# Test case where the size is too large to fit in the file, but the start is
|
|
# within the file.
|
|
# RUN: cp %t.stripped %t.truncated1
|
|
# RUN: %python -c "with open(r'%t.truncated1', 'r+') as f: f.truncate(0x1001)"
|
|
# RUN: not llvm-readobj %t.truncated1 --dynamic-table 2>&1 | FileCheck %s
|
|
|
|
# Test case where the offset is too large to be in the file.
|
|
# RUN: cp %t.stripped %t.truncated2

|
|
# RUN: not llvm-readobj %t.truncated2 --dynamic-table 2>&1 | FileCheck %s
|
|
|
|
# CHECK: error: PT_DYNAMIC segment offset + size exceeds the size of the file
