2020-03-11PR25651, objcopy SIGSEGV in copy_objectAlan Modra1-0/+9
With the right set of options, the second block of code dealing with padding can see a different section count. So don't use the new count. Since I was editing those lines, I've also changed the code allocating arrays a little. array = malloc (n * sizeof (*array)); for an array of ints is just better than array = malloc (n * sizeof (int)); It's easier to write correctly in the first place and more robust against code changes that might modify the array element type. PR 25651 * objcopy.c (copy_object): Test "gaps" not gap_fill_set or pad_to_set on second block of code dealing with padding. Replace "c" with "num_sec" and don't recalculate number of sections on second block. Size arrays using sizeof (element) rather than sizeof (element type).

2020-03-06binutils: doc: move artifacts back to MAINTAINERCLEANFILESSimon Marchi1-0/+6
In commit 2b44a6a237 (" binutils: doc: make `make clean` clean more things"), I moved the doc build artifacts to MOSTLYCLEANFILES, which made them get removed by "make clean". Because generating binutils.info requires makeinfo, and we do not want to require makeinfo when building from the tarball, binutils.info should not get removed by "make clean" (otherwise, it won't be included in the tarball). And to be consistent with other projects (e.g. ld and gas), we also want to ship the built man pages in the tarball. This patch puts back all these in MAINTAINERCLEANFILES, so that they are bundled in the tarball, and only cleaned if you use "make maintainer-clean". Tested by building a source release and confirming they are present. binutils/ChangeLog: PR 25491 * doc/Makefile.am: Rename MOSTLYCLEANFILES to MAINTAINERCLEANFILES. * doc/Makefile.in: Re-generate.

2020-02-20RISC-V: Support the ISA-dependent CSR checking.Nelson Chu1-0/+5
According to the riscv privilege spec, some CSR are only valid when rv32 or the specific extension is set. We extend the DECLARE_CSR and DECLARE_CSR_ALIAS to record more informaton we need, and then check whether the CSR is valid according to these information. We report warning message when the CSR is invalid, so we have a choice between error and warning by --fatal-warnings option. Also, a --no-warn/-W option is used to turn the warnings off, if people don't want the warnings. gas/ * config/tc-riscv.c (enum riscv_csr_class): New enum. Used to decide whether or not this CSR is legal in the current ISA string. (struct riscv_csr_extra): New structure to hold all extra information of CSR. (riscv_init_csr_hash): New function. According to the DECLARE_CSR and DECLARE_CSR_ALIAS, insert CSR extra information into csr_extra_hash. Call hash_reg_name to insert CSR address into reg_names_hash.

(init_opcode_hash): Update 'if (hash_error != NULL)' as hash_error is not a boolean. This is same as riscv_init_csr_hash, so keep the consistent usage. * testsuite/gas/riscv/csr-dw-regnums.d: Add -march=rv32if option. * testsuite/gas/riscv/priv-reg.d: Add f-ext by -march option. * testsuite/gas/riscv/priv-reg-fail-fext.d: New testcase.

2020-02-19Merge changes from GCC for the config/ directoryAndrew Burgess1-0/+4
GCC's config/ChangeLog since the last time this merge was done (in the binutils-gdb commit 0b4d000cc4e8e77c823) is included at the end of this commit message. It is worth noting that the binutils-gdb commit 301a9420d947da1458 added the file config/debuginfod.m4 which is not present in GCC's config/ directory. This file is preserved, unmodified, after this commit. In order to regenerate all of the configure files, I configured with --enable-maintainer-mode, and built the 'all' target. I then did the same thing on a source tree without this patch, and only committed those files that changed when this patch was added.

2020-02-02ELF: Add support for unique section ID to assemblerH.J. Lu1-0/+6
Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.
