<br>
Prepares a set of files ("symfs") to be used with profilers such as perf for<br>
converting binary addresses into human readable function names.<br>
<br>
Args:<br>
device: DeviceUtils instance identifying the target device.<br>
symfs_dir: Path where the symfs should be created.<br>
libraries: Set of library file names that should be included in the symfs.<br>
use_symlinks: If True, link instead of copy unstripped libraries into the<br>
symfs. This will speed up the operation, but the resulting symfs will no<br>
longer be valid if the linked files are modified, e.g., by rebuilding.<br>
<br>
Returns:<br>
The absolute path to the kernel symbols within the created symfs.</tt></dd></dl>

<dl><dt><a name="-GetToolchainBinaryPath"><strong>GetToolchainBinaryPath</strong></a>(library_file, binary_name)</dt><dd><tt>Return the path to an Android toolchain binary on the host.<br>
<br>
Args:<br>
library_file: ELF library which is used to identify the used ABI,<br>
architecture and toolchain.<br>
binary_name: Binary to search for, e.g., 'objdump'<br>
Returns:<br>
Full path to binary or None if the binary was not found.</tt></dd></dl>
