PR gas/11395
* config/tc-hppa.c (pa_ip): Do not allow 64-bit add condition
matcher to accept and unconditional 32-bit add instruction.
(pa_build_unwind_subspace): Cope with error conditions not
allowing the start symbol to be set.
* gas/hppa/basic/add2.s: Add test of simple 32-bit instruction.
* gas/hppa/basic/basic.exp (do_add2): Add grep for expected
disassembly.
