Did you have a look at the .lst file ?
I included the last part of it below :
000000 363 _main:
000007 364 ar7 = 0x07
000006 365 ar6 = 0x06
000005 366 ar5 = 0x05
000004 367 ar4 = 0x04
000003 368 ar3 = 0x03
000002 369 ar2 = 0x02
000001 370 ar1 = 0x01
000000 371 ar0 = 0x00
372 ; main.c:7: char *c = (char
*)malloc(20 * sizeof(char));
000000 90 00 14 [24] 373 mov dptr,#0x0014
000003 12r00r00 [24] 374 lcall _malloc
000006 AE 82 [24] 375 mov r6,dpl
000008 AF 83 [24] 376 mov r7,dph
00000A 7D 00 [12] 377 mov r5,#0x00
378 ; main.c:10: strncpy(c,
"inicializando", 6);
00000C 75*00r00 [24] 379 mov _strncpy_PARM_2,#__str_0
00000F 75*01s00 [24] 380 mov (_strncpy_PARM_2 + 1),#(__str_0
>> 8)
000012 75*02 80 [24] 381 mov (_strncpy_PARM_2 + 2),#0x80
000015 75*00 06 [24] 382 mov _strncpy_PARM_3,#0x06
000018 75*01 00 [24] 383 mov (_strncpy_PARM_3 + 1),#0x00
00001B 8E 82 [24] 384 mov dpl,r6
00001D 8F 83 [24] 385 mov dph,r7
00001F 8D F0 [24] 386 mov b,r5
000021 12r00r00 [24] 387 lcall _strncpy
388 ; main.c:11: while(1)
000024 389 00102$:
000024 80 FE [24] 390 sjmp 00102$
391 .area CSEG (CODE)
392 .area CONST (CODE)
000000 393 __str_0:
000000 69 6E 69 63 69 61 6C 394 .ascii "inicializando"
69 7A 61 6E 64 6F
00000D 00 395 .db 0x00
I have sdcc setup for 8051/8052 code generation only :
#include <8052.h>
#include <stdlib.h>
#include <string.h>
void main(void)
{
char *c = (char *)malloc(20 * sizeof(char));
// char c[20];
strncpy(c, "inicializando", 6);
while(1)
{
}
}
sdcc main.c
SDCC : mcs51 3.3.1 #8894 (17 Oct 2013) (Linux)
I also tried without the malloc function, the resulting hex file
is shorter.
