In non-multilib installations system headers may not be available for
compilation options using a non-default model, causing build errors such
as:
In file included from .../include/features.h:527,
from .../include/assert.h:35,
from
.../gcc/testsuite/gcc.target/riscv/rvv/autovec/vmv-imm-template.h:2,
from
.../gcc/testsuite/gcc.target/riscv/rvv/autovec/vmv-imm-fixed-rv32.c:4:
.../include/gnu/stubs.h:11:11: fatal error: gnu/stubs-ilp32d.h: No such file or
directory
Therefore we have to be very cautious when trying to use a non-default
model in the testsuite, preferably avoiding to rely on headers that have
not been supplied by GCC itself, or otherwise verifying in a preparatory
step whether the given model is buildable in a given test environment.
In this case however we can easily avoid the issue, because <assert.h>
facilities are not used at all by "vmv-imm-template.h", which includes
the header. Remove the inclusion then, turning these issues:
