Fix empty DWARF expressions DATA vs. SIZE conditionals.
* dwarf2loc.c (dwarf2_find_location_expression): Clear *LOCEXPR_LENGTH.
(dwarf_expr_frame_base_1): Indicate unavailability via zero *LENGTH.
(locexpr_tracepoint_var_ref): Check only zero SIZE, not zero DATA.
(loclist_read_variable, loclist_tracepoint_var_ref): Do not check for
zero DATA.
* dwarf2loc.h (struct dwarf2_locexpr_baton): Comment DATA vs. SIZE
validity.
* dwarf2read.c (struct dwarf_block): Comment DATA validity.
(dwarf2_fetch_die_location_block, dwarf2_symbol_mark_computed): Do not
clear DATA on zero SIZE.
gdb/testsuite/
Fix empty DWARF expressions DATA vs. SIZE conditionals.
* gdb.dwarf2/dw2-op-call.S (arraycallnoloc, arraynoloc): New DIEs.
(loclist): New.
(4): New abbrev.
* gdb.dwarf2/dw2-op-call.exp: Remove variable srcfile and executable.
Use prepare_for_testing, remove clean_restart.
(p arraynoloc, p arraycallnoloc): New tests.
