Subject: Fix _GLOBAL_OFFSET_TABLE_ value for large GOTs (aarch64).
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a45a8f9178448171b51d9fc80d45ede73e99e399;p=binutils-gdb.git

Fix _GLOBAL_OFFSET_TABLE_ value for large GOTs (aarch64).

Gold resolves GOT-relative relocs relative to the GOT base +
0x8000 when the GOT is larger than 0x8000. However, previously
the _GLOBAL_OFFSET_TABLE_ symbol was set to GOT base + 0x8000
when the .got.plt was larger than 0x8000. This patch makes both
checks use the size of the .got section so that they agree when
to add 0x8000.
