And that is even more true fro pic14 than for pic16. I suggest you try just taking puts() from sdcc/device/lib/puts.c and see if it works for you for pic14. Philipp |

From a quick look at sdcc/device/lib/pic1?, it seems that the pic14 doesn't really have a library (expect for support functions and floating-point math functions) and the pic16 has its own library, separate from what all the non-pic backends use.

I haven't been using the keyword __at much. But now I have a case where I want code to be placed in the 0x0000 to 0x9fff range. However, at the specific location 0x1ff0 I want 16 specific header bytes. The linker should just put the code around the header (which might require leaving a few bytes unused), but it doesn't work for me so far. I tried const struct header __at(0x1ff0) header = ...; but the linker creates an overlap: The header gets put into the binary at the correct location with the correct data. But that means the data ends up in the middle of a function. Philipp |

PIC microcontrollers (PIC12/PIC14/PIC16) doesn't have a general purpose stack (it has a hardware stack used only to sub-routines and interrupts return). I don't known how the sdcc implements local variables for these targets (may be a software stack or fixed allocation).

Local variables on stack don't even have a name in assembler. Hav you considered using static variables? Maarten |

Hello, I think that is the only way using global variables if you want to use inline assembly. Better solution is writing time critical function in assembly and compile source codes into object files and linking them. There is some help in the sdcc manual how is it working and how can you give parameters to assembly functions.

Access to global variable is no problem, just use _varname, but how can I access local variables? Is there no other way than using the compiler-generated names (which may change if the code is changed)? BR Erlo |

Hi,
I copypasted the def from your mail to my main.c where that
function is used and changed the name to memcpypgm2ram_test:
_data void *
memcpypgm2ram_test (__data void *dst, __code void *src, size_t acount)
{
char __data *d = dst;
char __code *s = src;
/*
* copy from lower addresses to higher addresses
*/
while (acount--)
*d++ = *s++;
return dst;
}
This procudes these errors, maybe they tell you more than what they tell to me.
main.c:689: error 78: incompatible types
from type 'struct __00000981 near* data'
to type 'const-void code* fixed'
main.c:690: error 78: incompatible types

Hi,
regarding the warning: This seems to be a bug. We have
__data void *
memcpypgm2ram (__data void *dst, __code void *src, size_t acount)
{
char __data *d = dst;
char __code *s = src;
/*
* copy from lower addresses to higher addresses
*/
while (acount--)
*d++ = *s++;
return dst;
}
src and s should have const qualifiers, no? One might think that _code
should imply const - but if i remember correctly, that was true in most but
not all cases... Maybe we imply a const in the return of your function but
not in the arguments? Strange...
You could try copying the library function to your project and adjust the
arguments (and s) just to see if it helps?
Regarding the second issue: Do you link main.o twice by any chance? Maybe
by compiling main.c once as part of the sources and again to trigger
linking with all .o files including main.o?
Could you post all relevant build output - with verbose enabled to see the
files being linked?
If the error occurs during compilation - could you provide the .asm file?
(sdcc with -S and -o foo.asm could do the trick)?
I'll be unavailable for the next week or so and may not be able to read or
answer mail :-(.

I'm runnin sdcc 3.4.0 and targeting PIC18F45K50
I get this warning:
main.c:670: warning 196: pointer target lost const qualifier
from this:
memcpypgm2ram(&hid_tx_buffer.uint8[0],get_toad4_config(),63);
with these defs:
__code void* get_toad4_config();
volatile hid_buffer_t hid_tx_buffer;
this however does not produce any warning:
memcpyram2ram(&hid_tx_buffer.uint8[0], &g_toad4_status.steppers[0],8);
so I'm thinking it is the get_toad4_config() that produces the warning.
I don't get it.
Also slightly related:
I get this:
../obj/main.asm:3683:Error[154] Each object file section must be
contiguous: ".code"
../obj/main.asm:3683:Error[116] Address label duplicated or different in
second pass: "_g_toad4_config"
Error[181] System error while writing object file.
if I have anything like this:
__code int g_toad4_config = {0};
in my main.c but not if I have it in any other source file.

Hi,
i just checked crt0i:
/* The cinit table will be filled by the linker. */
extern __code struct
{
unsigned short num_init;
struct
{
unsigned long from;
unsigned long to;
unsigned long size;
} entries[1];
} cinit;
Maybe your initialised variable section is empty because you have none?
Could you try adding some
static char foo = 42;
and try again?

Hi,
you seem to pass --no-crt to sdcc and pass in your own crt0iz_toad4.o.
Could this be the problem? Can the order be bad? Maybe have the linker look
at crt0iz last? I'm not sure where _cinit is supposed to come from...
Best regards,

Hi,
I'm using sdcc-stm8 with following code:
struct FLASH_t { ... ; volatile uint8_t iapsr; ...};
#define FLASH ((struct FLASH_t *)BASE_ADDRESS_OF_FLASH_CONTROLLER)
Program waits end of flash operation in a busy loop:
while ((FLASH->iapsr & 5) == 0) ...;
it works well rereading value of iapsr in every check. But in
following structure:
uint8_t r= FLASH->iapsr;
while ((r & 5) == 0)
r= FLASH->iapsr;
iapsr is read just once and the cycle uses that value without
rereading the register. Even the following code uses the value which
has been read before the cycle:
uint8_t r= FLASH->iapsr & 5;
while ((FLASH->iapsr & 5) == 0) ...
It looks that "volatile"-ness of a struct member disappears in some
situations. Is it OK in C, or is it a bug?
Daniel

Hello, The sddc headers are generated from Microchip assembly processor header files (.inc). Here is the source ( p18f45k50.inc ): ;----- ADCON0 Bits ----------------------------------------------------- ADON EQU H'0000' GO_NOT_DONE EQU H'0001' DONE EQU H'0001' GO EQU H'0001' NOT_DONE EQU H'0001' another source ( p18f46k20.inc ): ;----- ADCON0 Bits ----------------------------------------------------- ADON EQU H'0000' GO_NOT_DONE EQU H'0001' DONE EQU H'0001' CHS0 EQU H'0002' CHS1 EQU H'0003' CHS2 EQU H'0004' CHS3 EQU H'0005' NOT_DONE EQU H'0001' GO_DONE EQU H'0001' GO EQU H'0001' I think Microchip missed the CHS bits from the .inc file and this is not sdcc bug.
