With the new ldp/stp pass enabled, there is a change in the codegen for
this test as follows:
add x8, sp, 16
ptrue p3.h, mul3
str p3, [x8]
- str x8, [sp, 8]
- str x9, [sp]
+ stp x9, x8, [sp]
ptrue p3.d, vl8
ptrue p2.s, vl7
ptrue p1.h, vl6
i.e. we now form an stp that we were missing previously. This patch
adjusts the scan-assembler such that it should pass whether or not
we form the stp.
Bootstrapped/regtested as a series on aarch64-linux-gnu, OK for trunk?
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/sve/pcs/args_9.c: Adjust scan-assemblers to
allow for stp.
