## i386-got32x-baseless.elf is a file produced using GNU as v.2.27
|
|
## using following code and command line:
|
|
## (as --32 -o base.o base.s)
|
|
##
|
|
## .text
|
|
## .globl foo
|
|
## .type foo, @function
|
|
## foo:
|
|
## nop
|
|
##
|
|
## _start:
|
|
## movl foo@GOT, %eax
|
|
## movl foo@GOT, %ebx
|
|
## movl foo@GOT(%eax), %eax
|
|
## movl foo@GOT(%ebx), %eax
|
|
##
|
|
## Result file contains four R_386_GOT32X relocations. Generated code
|
|
## is also a four mov instructions. And first two has no base register:
|
|
## <_start>:
|
|
## 1: 8b 05 00 00 00 00 mov 0x0,%eax
|
|
## 7: 8b 1d 00 00 00 00 mov 0x0,%ebx
|
|
## d: 8b 80 00 00 00 00 mov 0x0(%eax),%eax
|
|
## 13: 8b 83 00 00 00 00 mov 0x0(%ebx),%eax
|
|
##
|
|
## R_386_GOT32X is computed as G + A - GOT, but if it used without base
|
|
## register, it should be calculated as G + A. Using without base register
|
|
## is only allowed for non-PIC code.
