How can I get two page aligned(0x1000) and separated program headers?

问题

I am trying to implement custom loader and

want to locate two program headers(segment) for data and code with 0x1000 aligned.

I fixed some part of the default linker script and get weird results.

**Default linker script.**
. = ALIGN (CONSTANT (MAXPAGESIZE)) - ((CONSTANT (MAXPAGESIZE) - .) & 
(CONSTANT (MAXPAGESIZE) - 1));
. = DATA_SEGMENT_ALIGN (CONSTANT(MAXPAGESIZE),CONSTANT (COMMONPAGESIZE));

**Modified linker script**
. = ALIGN (0x1000);
. = DATA_SEGMENT_ALIGN(0x1000, 0x1000);

when I compiled the binary with default linker script, it is 0x200000 aligned

and have two program headers.

LOAD         0x0000000000000000 0x0000000050000000 0x0000000050000000
             0x0000000000001058 0x0000000000001058  R E    200000
LOAD         0x0000000000001fe8 0x0000000050201fe8 0x0000000050201fe8
             0x0000000000000028 0x00000000000000c0  RW     200000

but I get below result with modified linker script.

LOAD           0x0000000000000000 0x0000000050000000 0x0000000050000000
               0x0000000000002010 0x00000000000020a8  RWE    200000

It seems that the data section and code section is mixed in one program header.

However, I want to make my program have two page aligned(0x1000) program headers

LOAD1        0x0000000050000000 ~ 0x0000000050002340 R E
LOAD2        0x0000000050003000 ~ 0x0000000050006790 RW 

Please let me know some directions.
