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. (riscv_merge_std_ext): Updated since the field of rpe is changed. * elfxx-riscv.c (cpu-riscv.h): Removed. (riscv_implicit_subsets): Added implicit extensions for g. (struct riscv_supported_ext): Used to be riscv_ext_version. Moved from gas/config/tc-riscv.c, and added new field `default_enable' to decide if the extension should be enabled by default. (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. (riscv_supported_std_z_ext): Likewise, but is used for z* extensions. (riscv_supported_std_s_ext): Likewise, but is used for s* extensions.

2021-09-15bfd: fix incorrect type used in sizeofAndrew Burgess2-1/+6
Noticed in passing that we used 'sizeof (char **)' when calculating the size of a list of 'char *' pointers. Of course, this isn't really going to make a difference anywhere, but we may as well be correct. There should be no user visible changes after this commit. bfd/ChangeLog: * archures.c (bfd_arch_list): Use 'char *' instead of 'char **' when calculating space for a string list.

2021-09-14arc: Fix potential invalid pointer access when fixing got symbols.Claudiu Zissulescu2-37/+66
When statically linking, it can arrive to an undefined weak symbol of which its value cannot be determined. However, we are having pieces of code which doesn't take this situation into account, leading to access a structure which may not be initialized.

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.
2021-09-02PTR_ADD and NPTR_ADD for bfd.hAlan Modra4-25/+38
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.
