All cores which add a cpu_addrcost_table use a non-zero value for HI and TI...
All cores which add a cpu_addrcost_table use a non-zero value for
HI and TI mode shifts (a non-zero value for general indexing also
applies to all shifts). Given this, it makes no sense to use a
different setting in generic_addrcost_table. So change it so that
all supported cores, including -mcpu=generic, now generate the same:
int f(short *p, short *q, long x) { return p[x] + q[x]; }
lsl x2, x2, 1
ldrsh w3, [x0, x2]
ldrsh w0, [x1, x2]
add w0, w3, w0

* config/aarch64/aarch64.c (generic_addrcost_table):
Change HI/TI mode setting.
