[PATCH 2/4] revert: use getn_sha1() to simplify insn parsing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

To read the object name in the instruction sheet, we currently
manipulate the buffer to artificially introduce a NUL after the
supposed object name, and then use get_sha1() to read the object name
before restoring the buffer.  Get rid of this ugliness by using
getn_sha1(), a function introduced in the previous patch.
