While this may seem safe, and likely is on any 64-bit system,
it may not be entirely well defined. And in this case we should
not have to worry about copying.
Maybe fixes T8276...
This is unnecessary because for all contexts where type is
relevant the validator already makes sure the type and expression
match correctly, so you don't ever need to re-validate it. If you
are doing a generic case and are not sure, just use MASK_ALL.
Complex types (i.e. list, array, hash, accessor etc.) now do not require
pointers with them anymore (the pointer is implied) and the same goes for
class handles. Eolian now explicitly disallows creating pointers to these
as well. This is the first part of the work to remove pointers from Eolian
completely, with the goal of simplifying the DSL (higher level) and therefore
making it easier for bindings (as well as easier API usage).
@feature
This adds a few new APIs to retrieve the type of an expression, operators
for binary and unary expressions, lhs/rhs for binary expressions, expr for
unary expressions and value for other expressions.
Because of Eina_Value being less than optimal in our usage, we're dropping it in Eolian.
This simplifies the code and makes it easier to bind to other languages, which
will aid new generators. Also, we're dropping long double support from eo files
and expressions as it causes an ABI breakage in gcc 4.4.
so instead of "unsigned int" you get "uint". This is important for handling of
expressions and cross-language interoperability. You can use c_type_get on the
base type to get the C name. Also, append the appropriate suffix to number literals
when calling eolian_expression_value_to_literal.
This commit also does several side (related) changes. Particularly, it updates
the Eolian C generator to use the new API, it adds missing expr types (null, char)
and masks, updates the API dealing with default return values to use expressions
instead of strings and does several fixes (mainly in lexer) around the place.
It also disallows single quoted strings as those are reserved for characters.
