Andrew Burgess	6a7f57668a	riscv: print .2byte or .4byte before an unknown instruction encoding When the RISC-V disassembler encounters an unknown instruction, it currently just prints the value of the bytes, like this: Dump of assembler code for function custom_insn: 0x00010132 <+0>: addi sp,sp,-16 0x00010134 <+2>: sw s0,12(sp) 0x00010136 <+4>: addi s0,sp,16 0x00010138 <+6>: 0x52018b 0x0001013c <+10>: 0x9c45 My proposal, in this patch, is to change the behaviour to this: Dump of assembler code for function custom_insn: 0x00010132 <+0>: addi sp,sp,-16 0x00010134 <+2>: sw s0,12(sp) 0x00010136 <+4>: addi s0,sp,16 0x00010138 <+6>: .4byte 0x52018b 0x0001013c <+10>: .2byte 0x9c45 Adding the .4byte and .2byte opcodes. The benefit that I see here is that in the patched version of the tools, the disassembler output can be fed back into the assembler and it should assemble to the same binary format. Before the patch, the disassembler output is invalid assembly. I've started a RISC-V specific test file under binutils so that I can add a test for this change. binutils/ChangeLog: * testsuite/binutils-all/riscv/riscv.exp: New file. * testsuite/binutils-all/riscv/unknown.d: New file. * testsuite/binutils-all/riscv/unknown.s: New file. opcodes/ChangeLog: * riscv-dis.c (riscv_disassemble_insn): Print a .%dbyte opcode before an unknown instruction, '%d' is replaced with the instruction length.	5 years ago

Alan Modra	ad77db1c02	CC_FOR_TARGET et al The top level Makefile, the ld Makefile and others, define CC_FOR_TARGET to be a compiler for the binutils target machine. This is the compiler that should be used for almost all tests with C source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS too. This was all supposed to work with the testsuite .exp files using CC for the target compiler, and CC_FOR_HOST for the host compiler, with the makefiles passing CC=$CC_FOR_TARGET and CC_FOR_HOST=$CC to the runtest invocation. One exception to the rule of using CC_FOR_TARGET is the native-only ld bootstrap test, which uses the newly built ld to link a copy of itself. Since the files being linked were created with the host compiler, the boostrap test should use CC and CFLAGS, in case some host compiler option provides needed libraries automatically. However, bootstrap.exp used CC where it should have used CC_FOR_HOST. I set about fixing that problem, then decided that playing games in the makefiles with CC was a bad idea. Not only is it confusing, but other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp. So this patch gets rid of the makefile variable renaming and changes all the .exp files to use the correct _FOR_TARGET variables. CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will correct bootstrap.exp to use CFLAGS, and a number of other things I noticed. binutils/ * testsuite/lib/binutils-common.exp (run_dump_test): Use CC_FOR_TARGET and CFLAGS_FOR_TARGET rather than CC and CFLAGS. ld/ * Makefile.am (check-DEJAGNU): Don't set CC to CC_FOR_TARGET and similar.

Alan Modra	36f61bf2ad	PTR_ADD and NPTR_ADD for bfd.h This defines a couple of macros used to avoid ubsan complaints about calculations involving NULL pointers. PTR_ADD should be used in the case where it is known that the offset is always zero with a NULL pointer, and you'd like to know if a non-zero offset is ever used. NPTR_ADD should be rarely used, but is defined for cases where a non-zero offset is expected and should be ignored if the pointer is NULL. bfd/ * bfd-in.h (PTR_ADD, NPTR_ADD): Define. * bfd-in2.h: Regenerate. * elf-eh-frame.c (adjust_eh_frame_local_symbols): Avoid NULL pointer calculations. * elflink.c (_bfd_elf_strip_zero_sized_dynamic_sections): Likewise.

Nelson Chu	9b9b1092f0	RISC-V: PR27916, Support mapping symbols. Similar to ARM/AARCH64, we add mapping symbols in the symbol table, to mark the start addresses of data and instructions. The $d means data, and the $x means instruction. Then the disassembler uses these symbols to decide whether we should dump data or instruction. Consider the mapping-04 test case, $ cat tmp.s .text .option norelax .option norvc .fill 2, 4, 0x1001 .byte 1 .word 0 .balign 8 add a0, a0, a0 .fill 5, 2, 0x2002 add a1, a1, a1 .data .word 0x1 # No need to add mapping symbols. .word 0x2 $ riscv64-unknown-elf-as tmp.s -o tmp.o $ riscv64-unknown-elf-objdump -d tmp.o Disassembly of section .text: 0000000000000000 <.text>: 0: 00001001 .word 0x00001001 # Marked $d, .fill directive. 4: 00001001 .word 0x00001001 8: 00000001 .word 0x00000001 # .byte + part of .word. c: 00 .byte 0x00 # remaining .word. d: 00 .byte 0x00 # Marked $d, odd byte of alignment. e: 0001 nop # Marked $x, nops for alignment. 10: 00a50533 add a0,a0,a0 14: 20022002 .word 0x20022002 # Marked $d, .fill directive. 18: 20022002 .word 0x20022002 1c: 2002 .short 0x2002 1e: 00b585b3 add a1,a1,a1 # Marked $x. 22: 0001 nop # Section tail alignment. 24: 00000013 nop * Use $d and $x to mark the distribution of data and instructions. Alignments of code are recognized as instructions, since we usually fill nops for them. * If the alignment have odd bytes, then we cannot just fill the nops into the spaces. We always fill an odd byte 0x00 at the start of the spaces. Therefore, add a $d mapping symbol for the odd byte, to tell disassembler that it isn't an instruction. The behavior is same as Arm and Aarch64. The elf/linux toolchain regressions all passed. Besides, I also disable the mapping symbols internally, but use the new objudmp, the regressions passed, too. Therefore, the new objudmp should dump the objects corretly, even if they don't have any mapping symbols. bfd/ pr 27916 * cpu-riscv.c (riscv_elf_is_mapping_symbols): Define mapping symbols. * cpu-riscv.h: extern riscv_elf_is_mapping_symbols. * elfnn-riscv.c (riscv_maybe_function_sym): Do not choose mapping symbols as a function name.

John Ericson	ab4f385b3c	Deprecate a.out support for NetBSD targets. 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.

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.

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. Delete "end" parameter, use initial "data" pointer as the end. Formatting. Don't count down bytes as they are read. (read_and_display_attr_value): Adjust display_discr_list call.

Alan Modra	93df3340fd	readelf: report DF_1_PIE as "Position-Independent Executable" 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.
