ld链接脚本(*.lds)示例

.text 程序代码
.rodata 只读数据
.data 可读写且需要初始化数据
.bss 可读写的置零初始化数据

SECTION格式

 section [address] [(type)] :
   [AT(lma)]   [ALIGN(section_align) | ALIGN_WITH_INPUT]   [SUBALIGN(subsection_align)]   [constraint]

示例

ENTRY(symbol)
 SECTIONS
 {
   . = SIZEOF_HEADERS;
   .interp :
   { *(.interp) } :text :interp 
   . = 0x10000;
   .text :
   { head.o(.text); *(.text) }
   //.text ALIGN(0x10) : { *(.text) }
   //.text 0x10000: { *(.text) }
   //.text { o1/*.o(.text); }
   . = . + 0x100;
   . = ALIGN(0x8000)
   //variable = ALIGN(0x8000)
   .rodata : { *(.rodata) }
   .mdata 0x20000 :
     AT ( ADDR (.text) + SIZEOF (.text) )
     { _data = . ; *(.data); _edata = . ;  }
   . = 0x8000000;
   .data : { *(.data) }
   .bss : { *(.bss) }
