2021-09-17RISC-V: Merged extension string tables and their version tables into one.Nelson Chu3-137/+228
There are two main reasons for this patch, * In the past we had two extension tables, one is used to record all supported extensions in bfd/elfxx-riscv.c, another is used to get the default extension versions in gas/config/tc-riscv.c. It is hard to maintain lots of tables in different files, but in fact we can merge them into just one table. Therefore, we now define many riscv_supported_std* tables, which record names and versions for all supported extensions. We not only use these tables to initialize the riscv_ext_order, but also use them to get the default versions of extensions, and decide if the extensions should be enbaled by default. * We add a new filed `default_enable' for the riscv_supported_std* tables, to decide if the extension should be enabled by default. For now if the `default_enable' field of the extension is set to EXT_DEFAULT, then we should enable the extension when the -march and elf architecture attributes are not set. In the future, I suppose the `default_enable' can be set to lots of EXT_<VENDOR>, each vendor can decide to open which extensions, when the target triple of vendor is chosen. The elf/linux regression tests of riscv-gnu-toolchain are passed. bfd/ * elfnn-riscv.c (cpu-riscv.h): Removed sine it is included in bfd/elfxx-riscv.h.

(EXT_DEFAULT): Defined for `default_enable' field. (riscv_supported_std_ext): It used to return the supported standard architecture string, but now we move ext_version_table from gas/config/tc-riscv.c to here, and rename it to riscv_supported_std_ext. Currently we not only use the table to initialize riscv_ext_order, but also get the default versions of extensions, and decide if the extensions should be enbaled by default.

2021-09-02SHT_SYMTAB_SHNDX handlingAlan Modra3-30/+13
.symtab_shndx section contents is an array, one entry for each symbol in .symtab, present when the number of symbols exceeds a little less than 64k. Since the mapping is 1-1 with symbols there is no need to keep both dest_index and destshndx_index in elf_sym_strtab. Instead, just make sure that the shndx pointers to the swap functions are kept NULL when .symtab_shndx does not exist. Also, strtabcount in the linker's elf hash table is incremented in lock-step with the output symcount, so that can disappear too.

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.

2021-08-30RISC-V: PR27916, Support mapping symbols.Nelson Chu3-3/+34
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.
