--- Comment #7 from Steve Ellcey <sje at gcc dot gnu.org> ---
I tested the patch on my aarch64 box, I got three regressions:
FAIL: gcc.target/aarch64/pr78733.c scan-assembler adr
FAIL: gcc.target/aarch64/pr79041-2.c scan-assembler adr
FAIL: gfortran.fortran-torture/compile/pr83081.f90, -O3 -g (internal
compiler error)
pr83081.f90 looks like a new test so it may not actually be a regression
related to this patch, but the first two are. pr79041-2 generates:
t:
mov x0, 0
mov x1, 65536
ret
with the patch rather than:
t:
adr x0, .LC0
ldp x0, x1, [x0]
ret
.size t, .-t
.align 4
.LC0:
.xword 0
.xword 65536
