2021-08-11Deprecate a.out support for NetBSD targets.John Ericson3-1380/+1374
As discussed previously, a.out support is now quite deprecated, and in some cases removed, in both Binutils itself and NetBSD, so this legacy default makes little sense. `netbsdelf*` and `netbsdaout*` still work allowing the user to be explicit about there choice. Additionally, the configure script warns about the change as Nick Clifton requested. One possible concern was the status of NetBSD on NS32K, where only a.out was supported. But per [1] NetBSD has removed support, and if it were to come back, it would be with ELF. The binutils implementation is therefore marked obsolete, per the instructions in the last message. With that patch and this one applied, I have confirmed the following: --target=i686-unknown-netbsd --target=i686-unknown-netbsdelf builds completely --target=i686-unknown-netbsdaout properly fails because target is deprecated. --target=vax-unknown-netbsdaout builds completely except for gas, where the target is deprecated.

2021-07-21Remove `netbsdpe` supportJohn Ericson3-3/+2
netbsdpe was deprecated in c2ce831330e10dab4703094491f80b6b9a5c2289. Since then, a release has passed (2.37), and it was marked obselete in 5c9cbf07f3f972ecffe13d858010b3179df17b32. Unless I am mistaken, that means we can now remove support altogether. All branches in the "active" code are remove, and the target is additionally marked as obsolete next to the other removed ones for libbfd and gdb. Per [1] from the NetBSD toolchain list, PE/COFF support was removed a decade ago. Furthermore, the sole mention of this target in the binutils commit history was in 2002. Together, I'm led to believe this target hasn't seen much attention in quite a while.

2021-07-13RISC-V: Enable elf attributes when default configure option isn't set.Nelson Chu6-1/+9
Since gcc commit, 3c70b3ca1ef58f302bf8c16d9e7c7bb8626408bf, we now enable elf attributes for all riscv targets by default in gcc. Therefore, I think binutils should have the same behavior, in case users are writing assembly files. If --enable-default-riscv-attribute isn't set, then we enable the elf attributes for all riscv targets by default.

2021-07-10PR28069, assertion fail in dwarf.c:display_discr_listAlan Modra3-21/+26
We shouldn't be asserting on anything to do with leb128 values, or reporting file and line numbers when something unexpected happens. leb128 data is of indeterminate length, perfect for fuzzer mayhem. It would only make sense to assert or report dwarf.c/readelf.c source lines if the code had already sized and sanity checked the leb128 values. After removing the assertions, the testcase then gave: <37> DW_AT_discr_list : 5 byte block: 0 0 0 0 0 (label 0, label 0, label 0, label 0, <corrupt> readelf: Warning: corrupt discr_list - unrecognized discriminant byte 0x5 <3d> DW_AT_encoding : 0 (void) <3e> DW_AT_identifier_case: 0 (case_sensitive) <3f> DW_AT_virtuality : 0 (none) <40> DW_AT_decimal_sign: 5 (trailing separate) So the DW_AT_discr_list was showing more data than just the 5 byte block. That happened due to "end" pointing a long way past the end of block, and uvalue decrementing past zero on one of the leb128 bytes. PR 28069 * dwarf.c (display_discr_list): Remove assertions.

I finally found time to teach readelf to identify PIEs in the file header display and program header display. So in place of "DYN (Shared object file)" which isn't completely true, show "DYN (Position-Independent Executable file)". It requires a little bit of untangling code in readelf due to process_program_headers setting up dynamic_addr and dynamic_size, needed to scan .dynamic for the DT_FLAGS_1 entry, and process_program_headers itself wanting to display the file type in some cases. At first I modified process_program_header using a "probe" parameter similar to get_section_headers in order to inhibit output, but decided it was cleaner to separate out locate_dynamic_sections. binutils/ * readelf.c (locate_dynamic_section, is_pie): New functions.

2021-05-29MIPS/opcodes: Do not use CP0 register names for control registersMaciej W. Rozycki3-2/+8
The CP0 control register set has never been defined, however encodings for the CFC0 and CTC0 instructions remained available for implementers up until the MIPS32 ISA declared them invalid and causing the Reserved Instruction exception[1]. Therefore we handle them for both assembly and disassembly, however in the latter case the names of CP0 registers from the regular set are incorrectly printed if named registers are requested. This is because we do not define separate operand classes for coprocessor regular and control registers respectively, which means the disassembler has no way to tell the two cases apart. Consequently nonsensical disassembly is produced like: cfc0 v0,c0_random Later the MIPSr5 ISA reused the encodings for XPA ASE MFHC0 and MTHC0 instructions[2] although it failed to document them in the relevant opcode table until MIPSr6 only. Correct the issue then by defining a new register class, OP_REG_CONTROL, and corresponding operand codes, `g' and `y' for the two positions in the machine instruction a control register operand can take. Adjust the test cases affected accordingly. While at it swap the regular MIPS opcode table "cfc0" and "ctc0" entries with each other so that they come in the alphabetical order.
