Detailed Description

Functor to set the level 1 renaming of SSA expressions.

Level 1 corresponds to function frames. This is to preserve locality in case of recursion

Definition at line 52 of file renaming_level.h.

Member Function Documentation

◆ has()

bool symex_level1t::has ( const renamedt< ssa_exprt, L0 > &  ssa) const
Returns
true if ssa has an associated index

Definition at line 83 of file renaming_level.cpp.

◆ insert()

void symex_level1t::insert ( const renamedt< ssa_exprt, L0 > &  ssa,
std::size_t  index 
)

Assume ssa is not already known.

Definition at line 59 of file renaming_level.cpp.

◆ insert_or_replace()

optionalt< std::pair< ssa_exprt, std::size_t > > symex_level1t::insert_or_replace ( const renamedt< ssa_exprt, L0 > &  ssa,
std::size_t  index 
)

Set the index for ssa to index.

Returns
if an index for ssa was already know, returns it's previous value.

Definition at line 67 of file renaming_level.cpp.

◆ operator()()

renamedt< ssa_exprt, L1 > symex_level1t::operator() ( renamedt< ssa_exprt, L0 l0_expr) const
Returns
an SSA expression similar to l0_expr where the L1 tag has been set to the value in current_names of the l1 object identifier of l0_expr

Definition at line 89 of file renaming_level.cpp.

◆ restore_from()

void symex_level1t::restore_from ( const symex_level1t other)

Insert the content of other into this renaming.

Definition at line 121 of file renaming_level.cpp.
