X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=10078f3e1d0cbebc5e6f7f4821d3ad41421ef1e0;p=gcc.git

AARCH64: ILP32: Fix aarch64_asan_shadow_offset

aarch64_asan_shadow_offset is using the wrong
offset for ILP32.  Change it to be a decent one.

ChangeLog:
* config/aarch64/aarch64.c (aarch64_asan_shadow_offset):
Fix ILP32 value.
