The current mechanism used for predefined macros is to first
compose a buffer with the textual definition of the macro:
#define <name> <value>
and then tokenize it. It's quite powerful/flexible but for
small, simple predefined macros it's a bit sad to have to
go throught this textual representation when we could directly
define them via create/bind_symbol().
This series does exactly this: it adds a function:
predefine() which allow to directly add the definition of a
simple macro (without args and with a single number or ident
as definition). It then contains the conversion of the concerned
predefined macros and is followed by some cleanups.
Changes since v1:
* do not use asprintf() anymore
* merge predefine() & predefinef()
* add a note about the Blackfin's builtins being now
unconditionally declared.
Thanks to Ramsay Jones for the review.
