struct PushAttributes;

TraitsExp

Dsymbol getDsymbolWithoutExpCtx(RootObject oarg);

Convert Expression or Type to corresponding Dsymbol, additionally stripping off expression contexts.

Some symbol related __traits ignore arguments expression contexts. For example:

 struct S { void f() {} }
 S s;
 pragma(msg, __traits(isNested, s.f));
 // s.f is `DotVarExp`, but `__traits(isNested)`` needs a `FuncDeclaration`.

This is used for that common __traits behavior.

Input oarg object to get the symbol for

Returns:

Dsymbol the corresponding symbol for oarg

d_uns64 getTypePointerBitmap(Loc loc, Type t, Array!d_uns64* data);

get an array of size_t values that indicate possible pointer words in memory if interpreted as the type given as argument

Returns:

the size of the type in bytes, d_uns64.max on error
