unix/modffi: Allow to compile modffi in OBJ_REPR_D mode.

2016-01-15T14:26:24+00:00

py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.

2016-01-11T00:49:27+00:00

The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t.

py: Change type signature of builtin funs that take variable or kw args.

2016-01-11T00:49:27+00:00

With this patch the n_args parameter is changed type from mp_uint_t to size_t.

py: Change type of .make_new and .call args: mp_uint_t becomes size_t.

2016-01-11T00:48:41+00:00

This patch changes the type signature of .make_new and .call object method slots to use size_t for n_args and n_kw (was mp_uint_t. Makes code more efficient when mp_uint_t is larger than a machine word. Doesn't affect ports when size_t and mp_uint_t have the same size.

py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.

2015-11-29T14:25:35+00:00

This allows the mp_obj_t type to be configured to something other than a pointer-sized primitive type. This patch also includes additional changes to allow the code to compile when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of mp_uint_t, and various casts.

py: Add MP_ROM_* macros and mp_rom_* types and use them.

2015-11-29T14:25:04+00:00

unix/modffi: Mark 'O' type specifier as implemented.

unix/modffi.c: cast first to intptr_t when casting from/to pointer

2015-09-23T01:54:31+00:00

This fixes errors like these ones: modffi.c: In function 'return_ffi_value': modffi.c:143:29: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] const char *s = (const char *)val; ^ modffi.c:162:20: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] return (mp_obj_t)val; ^ modffi.c: In function 'ffifunc_call': modffi.c:358:25: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] values[i] = (ffi_arg)a; ^ modffi.c:373:25: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] values[i] = (ffi_arg)s; ^ modffi.c:381:25: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] values[i] = (ffi_arg)bufinfo.buf; ^ modffi.c:384:25: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] values[i] = (ffi_arg)p->func; ^ These errors can be highlighted when building micropython from MIPS64 n32 because ffi_arg is 64-bit wide and the pointers on MIPS64 n32 are 32-bit wide, so it's trying to case an integer to a pointer (or vice-versa) of a different size. We should cast first the pointer (or the integer) to a pointer sized integer (intptr_t) to fix that problem. Signed-off-by: Vicente Olivert Riera

modffi: dlsym() doesn't set errno, so use ENOENT for OSError.

2015-08-30T21:20:08+00:00

This may be a bit confusing, as ENOENT is often rendered as "No such file or directory", but any other code would be only more confusing.

unix/modffi.c: get_buffer is allowed to return NULL if len=0.

2015-05-01T20:34:08+00:00

This is consistent with the logic in mp_get_buffer, and the code here is an inlined version of that function.
