* src/abg-ir.cc (elf_symbol::is_variable): Accept TLS objects as
variables too.
* src/abg-dwarf-reader.cc (eval_last_constant_dwarf_sub_expr)
(die_location_address): Add an output parameter to say if the
resulting constant value is a tls address or not.
(lookup_public_variable_symbol_from_elf): Use the proper
elf_symbol::is_variable() method, rather than trying to figure out
the low levels of what a variable is here. Also, cleanup the
condition.
(read_context::load_symbol_maps): Consider symbols of type
STT_TLS, when loading symbols for variables. Also, to avoir
symbols that are for versions, filter out symbols of type
STT_OBJECT and with a SHN_ABS section index.
(read_context::get_variable_address): If the address is for a tls
variable, do no try to adjust the address to arrange for things
like prelink. As that doesn't seem to affect TLS variables.
(dwarf_expr_eval_context::set_tls_addr): New data member.
(dwarf_expr_eval_context::dwarf_expr_eval_context): Initialize it.
(dwarf_expr_eval_context::set_tls_address): New accessors.
(dwarf_expr_eval_context::op_manipulates_stack): Handle
DW_OP_GNU_push_tls_address, a bit like DW_OP_form_tls_address, but
then, its result is a constant. Set the
dwarf_expr_eval_context::set_tls_addr flag when these two OPs are
run.
(die_member_offset): Adjust to the new signature of
eval_last_constant_dwarf_sub_expr.
* tests/data/test-diff-dwarf/libtest9-v0.so: New test input.
* tests/data/test-diff-dwarf/libtest9-v1.so: Likewise.
* tests/data/test-diff-dwarf/test9-report.txt: Likewise
* tests/data/test-diff-dwarf/test9-v0.cc: Source code for the
first input.
* tests/data/test-diff-dwarf/test9-v1.cc: Source code for the
second input.
* tests/test-diff-dwarf.cc: Run this harness on the two new inputs
above.
* tests/Makefile.am: Add the new inputs to the source distribution.
