Just tried with C bitfields:
================================
#include <stdint.h>
struct Reg_T {
unsigned int a : 3;
unsigned int b : 1;
unsigned int c : 4;
} __attribute__((packed));
volatile struct Reg_T Reg_A;
volatile struct Reg_T Reg_B;
volatile struct Reg_T Reg_C;
volatile uint8_t A;
volatile uint8_t B;
void main (void)
{
Reg_A = (struct Reg_T){ .a = 0, .b = 0, .c = 0 };
Reg_B = (struct Reg_T){ .a = 0, .b = 1, .c = 0 };
Reg_C = (struct Reg_T){ .a = 7, .b = 1, .c = 15 }
A = 0;
B = 255;
}
================================
Same type of result...
GCC back-end then?
