align memory start address

[Howave]

#pragma pack(4) is not effective for the arrays

more precisely, print platform alignment macro block into the generated memory header so that the output file could be reused on both platform.

The content in the generated code file should be like

#ifdef _MSC_VER
__declspec(align(4))
#else
__attribute__((aligned(4)))
#endif
static const unsigned char xxxxx[] = {
};

[Howave]

it's useless to add the macro into the generated memory header. Only if adding the macro to each array header.Test codes are as below:

[Howave]

#include <stdio.h>

_attribute_ ((aligned(4)))

static const unsigned char det1_param_bin[] = {
0xdd,
};

static const unsigned char det2_param_bin[] = {
0xdd,0x85,0x76,
};

static const unsigned char det3_param_bin[] = {
0xdd,0x85,
};

static const unsigned char det4_param_bin[] = {
0xdd,0x85,0x76,
};

_attribute_((packed)) static const unsigned char det5_param_bin[] = {
0xdd,0x85
};

int main(int argc, char **argv){
char *p = &det1_param_bin[0];
printf("det1_param_bin = %p\n", p);

p = &det2_param_bin[0];
printf("det2_param_bin = %p\n", p);

p = &det3_param_bin[0];
printf("det3_param_bin = %p\n", p);

p = &det4_param_bin[0];
printf("det4_param_bin = %p\n", p);

p = &det5_param_bin[0];
printf("det5_param_bin = %p\n", p);

return 0;

}

so, alignment macro should be added before both array definition.

// xyz.mem.h content

#ifdef _MSC_VER
__declspec(align(4))
#else
__attribute__((aligned(4)))
#endif
static const unsigned char xyz_param_bin[] = {
    0x07
};

#ifdef _MSC_VER
__declspec(align(4))
#else
__attribute__((aligned(4)))
#endif
static const unsigned char xyz_bin[] = {
    0x05
};
