The MIPS16 interlinking test for local functions expects to be assembled
with 32-bit addressing, otherwise causing assembly warnings:
.../ld/testsuite/ld-mips-elf/mips16-local-stubs-1.s: Assembler messages:
.../ld/testsuite/ld-mips-elf/mips16-local-stubs-1.s:16: Warning: la used to load 64-bit address; recommend using dla instead
Use the per-ABI framework then to run the test explicitly for o32 and
n32 ABIs only, replacing the `-mips4' option from the `as' tag with
`.module mips4' pseudo-op within the source itself so as to avoid
assembly errors:
Assembler messages:
Error: -mips4 conflicts with the other architecture options, which imply -mips3
with n32 testing for some targets, and ultimately removing these
regressions:
mips64-openbsd -FAIL: MIPS16 interlinking for local functions 1
mips64el-openbsd -FAIL: MIPS16 interlinking for local functions 1
