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.

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.

unix/modffi: Support passing float/double args.

py: Overhaul and simplify printf/pfenv mechanism.

2015-04-16T14:30:16+00:00

Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.

modffi: Implement 'O' type handling for func arguments.

2015-02-25T21:38:22+00:00

modffi: Add toplevel func() function to create a function by pointer.

2015-02-10T23:21:03+00:00

modffi: Add .addr() method to just get symbol address.

2015-02-05T22:19:43+00:00

modffi: 's' (string) return type: handle NULL properly (return None).
