I narrowed it down to a testcase.
This problem occurs when using the #5718 Feb 26 2010 release of sdcc.
It does not occur with #4818 (Jan 18 2008).
I have not tested more recent versions.
#include <string.h>
#include <stdint.h>
#define UIP_LLH_LEN 0
#define UIP_IP_BUF ((struct uip_ip_hdr
*)&uip_buf[UIP_LLH_LEN])
#define UIP_BUFSIZE 126
extern uint8_t * const uip_buf;
static uint32_t uip_buf32[(UIP_BUFSIZE + 3) / 4];
uint8_t * const uip_buf = (uint8_t * const) uip_buf32;
typedef union uip_ip6addr_t {
uint8_t u8[16];
uint16_t u16[8];
} uip_ip6addr_t;
struct uip_ip_hdr {
/* IPV6 header */
uint8_t vtc;
uint8_t tcflow;
uint16_t flow;
uint8_t len[2];
uint8_t proto, ttl;
uip_ip6addr_t srcipaddr, destipaddr;
};
void
uip_process(uint8_t flag)
{
UIP_IP_BUF->flow = 0x00;
return;
}
main (void)
{
uip_process(0);
return 0;
}
