This file contains invisible Unicode characters that are indistinguishable to humans but may be processed differently by a computer. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

elfcpp is a C++ library for reading and writing ELF information.  This
was written to support gold, the ELF linker, and may not be generally
useful.

elfcpp does not do file I/O.  It deals only with offsets and memory
data.

For efficiency, most accessors are templates with two arguments: the
ELF file class (32 or 64 bits) and the endianness.
