Follow-up Comment #5, bug #17922 (project lwip):
In my opinion the following Code does the same as using “_attribute_
((aligned (MEM_ALIGNMENT)))”. I’m not an expert in C programming and lwip
so there might be another problem.
#if MEM_ALIGNMENT == 1
static u8_t ram[MEM_SIZE + sizeof(struct mem) + MEM_ALIGNMENT];
#elif MEM_ALIGNMENT == 2
static u16_t ram16[(MEM_SIZE + sizeof(struct mem) + MEM_ALIGNMENT)>>1];
static u8_t *ram = (u8_t *)ram16;
#elif MEM_ALIGNMENT == 4
static u32_t ram32[(MEM_SIZE + sizeof(struct mem) + MEM_ALIGNMENT)>>2];
static u8_t *ram = (u8_t *)ram32;
#elif MEM_ALIGNMENT == 8
static u64_t ram64[(MEM_SIZE + sizeof(struct mem) + MEM_ALIGNMENT)>>3];
static u8_t *ram = (u8_t *)ram64;
#else
#error "unhandled MEM_ALIGNMENT size"
#endif
