1 | # Checking that when linking as standard, the BL and the GOT access both use |
| 2 | # the PLT. This link does not do anything special to maintain pointer equality | |
| 3 | # since there is no access which directly uses the address. | |
| 4 | # | |
| 5 | # Things this testcase checks: | |
| 6 | # 1) Fragment of IRELATIVE relocation is PCC_START with bounds and | |
| 7 | # permissions of PCC. | |
| 8 | # 2) GOT access uses IRELATIVE relocation in the PLTGOT when no direct access | |
| 9 | # to address is used. | |
| 10 | # 3) BL to an IFUNC branches to a PLT stub which uses the a PLTGOT slot | |
| 11 | # initialised by an IRELATIVE relocation against our resolver. | |
