2013-06-18Fix PR symtab/15391Tom Tromey1-4/+11
PR symtab/15391 is a failure with the DW_OP_GNU_implicit_pointer feature. I tracked it down to a logic error in read_pieced_value. The code truncates this_size_bits according to the type size and offset too early -- it should do it after taking bits_to_skip into account. This patch fixes the bug. While testing this, I also tripped across a latent bug because indirect_pieced_value does not sign-extend where needed. This patch fixes this bug as well. Finally, Pedro pointed out that a previous version implemented sign extension incorrectly. This version introduces a new gdb_sign_extend function for this. A couple of notes on this function: * It has the gdb_ prefix to avoid clashes with various libraries that felt free to avoid proper namespacing. There is a "sign_extend" function in a Tile GX header, in an SOM-related BFD header (and in sh64-tdep.c and as a macro in arm-wince-tdep.c, but those are ours...) * I looked at all the sign extensions in gdb and didn't see ones that I felt comfortable converting to use this function; in large part because I don't have a good way to test the conversion. Built and regtested on x86-64 Fedora 18. New test cases included; this required a minor addition to the DWARF assembler. Note that the DWARF CU made by implptrpiece.exp uses a funny pointer size in order to show the sign-extension bug on all platforms. * dwarf2loc.c (read_pieced_value): Truncate this_size_bits after taking bits_to_skip into account.

-Wpointer-sign catches all these cases across the codebase that should be using gdb_byte for raw target bytes.

Handle its invalid value. * dwarf2expr.h (struct dwarf_expr_context): New field ref_addr_size. * dwarf2loc.c (dwarf2_evaluate_loc_desc_full) (dwarf2_loc_desc_needs_frame): Initialize ctx->ref_addr_size. * dwarf2loc.h (dwarf2_per_cu_ref_addr_size): New declaration. * dwarf2read.c (decode_locdesc): Initialize ctx->ref_addr_size. (dwarf2_per_cu_ref_addr_size): New function. gdb/testsuite/ Fix DW_OP_GNU_implicit_pointer for DWARF32 v3+ on 64-bit arches. * gdb.dwarf2/implptr-64bit.S: New file. * gdb.dwarf2/implptr-64bit.exp: New file.

Remove excessive DWARF expressions memory duplication. * dwarf2loc.c (per_cu_dwarf_call): Remove variable back_to and its use for block.data. (indirect_pieced_value): Remove variable result. Remove variable back_to and its use for baton.data. (dwarf2_compile_expr_to_ax): Remove variable back_to and its use for block.data. * dwarf2read.c (dwarf2_fetch_die_location_block): Remove xmemdup. Update the function comment.

* dwarf2loc.c (dwarf2_evaluate_loc_desc_full) <DWARF_VALUE_STACK> (dwarf2_evaluate_loc_desc_full) <DWARF_VALUE_LITERAL>: New variable objfile_gdbarch. Fix BFD_ENDIAN_BIG case. gdb/testsuite/ * gdb.dwarf2/dw2-op-stack-value.S: New file. * gdb.dwarf2/dw2-op-stack-value.exp: New file.

Fix implicit pointer offsets. * dwarf2loc.c (indirect_pieced_value): Comment byte_offset. Use also ptr.OFFSET. gdb/testsuite/ Fix implicit pointer offsets. * gdb.dwarf2/implptr.c (add): New marker baz breakpoint. * gdb.dwarf2/implptr.exp (set baz breakpoint for implptr) (continue to breakpoint: continue to baz breakpoint for implptr) (sanity check element 0, sanity check element 1) (enter the inlined function, check element 0 for the offset) (check element 1 for the offset) (continue to breakpoint: ignore the second baz breakpoint): New tests. (set foo breakpoint for implptr): Update the breakpoint number.
