1# REQUIRES: x86 2 3## i386-got32x-baseless.elf is a file produced using GNU as v.2.27 4## using following code and command line: 5## (as --32 -o base.o base.s) 6## 7## .text 8## .globl foo 9## .type foo, @function 10## foo: 11## nop 12## 13## _start: 14## movl foo@GOT, %eax 15## movl foo@GOT, %ebx 16## movl foo@GOT(%eax), %eax 17## movl foo@GOT(%ebx), %eax 18## 19## Result file contains four R_386_GOT32X relocations. Generated code 20## is also a four mov instructions. And first two has no base register: 21## <_start>: 22## 1: 8b 05 00 00 00 00 mov 0x0,%eax 23## 7: 8b 1d 00 00 00 00 mov 0x0,%ebx 24## d: 8b 80 00 00 00 00 mov 0x0(%eax),%eax 25## 13: 8b 83 00 00 00 00 mov 0x0(%ebx),%eax 26## 27## R_386_GOT32X is computed as G + A - GOT, but if it used without base 28## register, it should be calculated as G + A. Using without base register 29## is only allowed for non-PIC code. 30## 31# RUN: ld.lld %S/Inputs/i386-got32x-baseless.elf -o %t1 32# RUN: llvm-objdump --section-headers -d %t1 | FileCheck %s 33 34## 73728 == 0x12000 == ADDR(.got) 35# CHECK: Sections: 36# CHECK: Name Size VMA 37# CHECK: .got.plt 0000000c 00403134 38# CHECK: <_start>: 39# CHECK-NEXT: 401115: 8b 05 {{.*}} movl 4202800, %eax 40# CHECK-NEXT: 40111b: 8b 1d {{.*}} movl 4202800, %ebx 41# CHECK-NEXT: 401121: 8b 80 {{.*}} movl -4100(%eax), %eax 42# CHECK-NEXT: 401127: 8b 83 {{.*}} movl -4100(%ebx), %eax 43 44# RUN: not ld.lld %S/Inputs/i386-got32x-baseless.elf -o /dev/null -pie 2>&1 | \ 45# RUN: FileCheck %s --check-prefix=ERR 46# ERR-COUNT-2: error: symbol 'foo' cannot be preempted; recompile with -fPIE 47
