- Subject: [PATCH] Fix zero_ext documentation
- Authentication-results: sourceware.org; auth=none
This patch fixes the documentation for the zero_ext bytecode description.
It removes parts that seemed like a copy/paste from ext, since zero_ext
zeros the bits to the left.
gdb/doc/ChangeLog:
* agentexpr.texi (byte): Fix zero_ext description.
