* gdb.trace/collection.exp (executable): New.
(binfile): Use it. (fpreg, spreg, pcreg): New. (test_register): Use gdb_test_multiple. Pass /x to print. (prepare_for_trace_test): New. (run_trace_experiment): Use "continue", not gdb_run_cmd. (gdb_collect_args_test, gdb_collect_argstruct_test) (gdb_collect_argarray_test, gdb_collect_locals_test): Use prepare_for_trace_test. (gdb_collect_registers_test): Use prepare_for_trace_test. Use fpreg, spreg and pcreg. (gdb_collect_expression_test, gdb_collect_globals_test): Use prepare_for_trace_test. (gdb_trace_collection_test): Use fpreg, spreg and pcreg. Don't try to detect tracing support here. Don't set breakpoints at `begin' or `end' here. <global scope>: Use clean_restart. Run to main before checking for tracing support. Check for for tracing support here.
