PHDR padding

["Udo A. Steinberg" <us15 at os dot inf dot tu-dresden dot de>]

Hi all,

What I'm looking for is a way to create a PHDR whose memsz is larger than
filesz such that the bytes beyond filesz are 0-padded (similar to how .bss
is handled). However, I do not have a .bss section and creating one just
for the purpose of padding seems weird. The linker script is as follows:

OUTPUT_FORMAT("elf32-i386", "elf32-i386", "elf32-i386")
OUTPUT_ARCH(i386)
ENTRY(__start)

PHDRS
{
    image   PT_LOAD;
}
 
SECTIONS
{
    . = 0x1000;
    
    .text :
    {      
        *(.text .text.* .gnu.linkonce.t.*)
    } : image
             
    .rodata :
    {        
        *(.rodata .rodata.* .gnu.linkonce.r.*)
    } : image
}

This results in the following ELF headers:

Program Header:
    LOAD off    0x00000058 vaddr 0x00001000 paddr 0x00001000 align 2**3
         filesz 0x000000b6 memsz 0x000000b6 flags r-x

Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .text         00000080  00001000  00001000  00000058  2**3
                  CONTENTS, ALLOC, LOAD, READONLY, CODE
  1 .rodata       00000036  00001080  00001080  000000d8  2**0
                  CONTENTS, ALLOC, LOAD, READONLY, DATA

I would like filesz to remain at 0xb6 and memsz to be page-aligned (0x1000).
Is there an easy way to do this?

Cheers,

	- Udo
