Detailed Description

Queries and caches compute_objsize results.   

Constructor & Destructor Documentation

◆ pointer_query()

pointer_query::pointer_query ( range_query * qry = nullptr)
explicit
Default ctor.  Initialize object with pointers to the range_query
instance to use or null.   

Member Function Documentation

◆ DISABLE_COPY_AND_ASSIGN()

pointer_query::DISABLE_COPY_AND_ASSIGN ( pointer_query )
private

◆ dump()

void pointer_query::dump ( FILE * dump_file,
bool contents = false )

◆ flush_cache()

void pointer_query::flush_cache ( )

◆ get_ref() [1/2]

bool pointer_query::get_ref ( tree ptr,
gimple * stmt,
access_ref * pref,
int ostype = 1 )
Retrieve the access_ref instance for a variable from the cache if it's
there or compute it and insert it into the cache if it's nonnonull.

◆ get_ref() [2/2]

const access_ref * pointer_query::get_ref ( tree ptr,
int ostype = 1 ) const
Return a pointer to the cached access_ref instance for the SSA_NAME
PTR if it's there or null otherwise.
