BitVecReplace

BitVecReplace

Description

Replace first occurrence of old pattern with new pattern.

Parameters

Name Direction Description
bv in Bitvector to modify
old_pattern in Pattern to find and replace
new_pattern in Pattern to replace with

Usage example (from documentation) 

  bool replaced = BitVecReplace(&flags, &old_pat, &new_pat);

Success

true if a replacement was made; bv reflects the new bits.

Failure

false if old_pattern was not found or the rewrite could not allocate; on allocator OOM bv is left in its pre-call state.
