[PATCH 20/24] exec: Declare abi_ptr type in its own 'tcg/abi_ptr.h' header
Posted by Philippe Mathieu-Daudé 1 year, 11 months ago 
The abi_ptr type is declared in "exec/cpu_ldst.h" with all
the load/store helpers. Some source files requiring abi_ptr
type don't need the load/store helpers. In order to simplify,
create a new "tcg/abi_ptr.h" header.

I'm unconvinced about this being tcg related, per se.
Leave it in include/exec/, with exec/user/abitypes.h.

With that,

Indeed:

$ git grep -w abi_ptr -- tcg
$
