2019-05-28binutils: CTF support for objdump and readelfNick Alcock1-0/+206
This introduces CTF support for objdump and readelf. objdump has the following new arguments: --ctf=SECTION: display CTF in the given SECTION --ctf-parent=SECTION: name of CTF section that is the parent of this section readelf has the above, and these two as well: --ctf-symbols=SECTION: name of symbol table section (optional) --ctf-strings=SECTION: name of string table section (optional) (objdump can always use BFD machinery to determine the applicable string and symbol tables automatically, so these arguments are unnecessary.) Nearly all the work is done by the ctf_dump machinery in libctf: most of the remaining work is option-processing and section-reading, and thus is different for objdump and readelf: the minimal amount of similar code remaining is, in my view, too small to share, particularly given that objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it doesn't have a bfd. I am not particularly satisfied with the way resources are freed in either of these (I was forced to do it at the top level, for lack of anywhere else to free resources allocated during option processing), but I can't see any better way to do it without introducing new infrastructure for no other purpose. There are essentially arbitrary ordering changes to the Makefile.in's order of libtool-related stuff that I can't get rid of, but they have no semantic effect. (It is possible that some hunks of these changes could be dropped, but that seems a bit risky to me.) binutils/ * objdump.c (ctf-api.h): New include. (dump_ctf_section_info): New variable.

2019-05-24aarch64: add STO_AARCH64_VARIANT_PCS and DT_AARCH64_VARIANT_PCSSzabolcs Nagy1-0/+20
The bottom 2 bits of st_other are used for visibility, the top 6 bits are de facto reserved for processor specific use. This patch defines a bits to mark function symbols that follow a variant procedure call standard with different register usage convention. A dynamic tag is also defined that marks modules with R_<CLS>_JUMP_SLOT relocations referencing symbols marked with STO_AARCH64_VARIANT_PCS. This can be used by dynamic linkers that support lazy binding to decide what registers need to be preserved during symbol resolution. binutils/ChangeLog: * readelf.c (get_aarch64_dynamic_type): Handle DT_AARCH64_VARIANT_PCS.

2019-03-13[BFD, LD, AArch64, 3/3] Add --pac-plt to enable PLTs protected with PAC.Sudakshina Das1-0/+2
This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds new definitions of PAC enabled PLTs and both BTI and PAC enabled PLTs. 2) It also defines the new dynamic tag DT_AARCH64_PAC_PLT for the PAC enabled PLTs. 3) This patch adds a new ld command line option: --pac-plt. In the presence of this option, the linker uses the PAC enabled PLTs and marks with DT_AARCH64_PAC_PLT. 4) In case both BTI and PAC are enabled the linker should pick PLTs enabled with both and also use dynamic tags for both.

enabled PLTs This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds a new ld command line option: --force-bti. In the presence of this option, the linker enables BTI with the GNU_PROPERTY_AARCH64_FEATURE_1_BTI feature. This gives out warning in case of missing gnu notes for BTI in inputs. 2) It also defines a new set of BTI enabled PLTs. These are used either when all the inputs are marked with GNU_PROPERTY_AARCH64_FEATURE_1_BTI or when the new --force-bti option is used. This required adding new fields in elf_aarch64_link_hash_table so that we could make the PLT related information more generic. 3) It also defines a dynamic tag DT_AARCH64_BTI_PLT. The linker uses this whenever it picks BTI enabled PLTs.

2018-12-14elf: Add PT_GNU_PROPERTY segment typeH.J. Lu1-16/+5
Linkers group input note sections with the same name into one output note section with the same name. One output note section is placed in one PT_NOTE segment. New linkers merge all input .note.gnu.property sections into one output .note.gnu.property section with a single NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older linkers treat input .note.gnu.property section as a generic note section and just concatenate all input .note.gnu.property sections into one output .note.gnu.property section without merging them, we may see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which are invalid. GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such that linker sets the bit for non-relocatable outputs. But it isn't sufficient: 1. It doesn't cover generic properties. 2. When -mx86-used-note=yes is passed to x86 assembler, the GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED property in object file and older linkers generate invalid NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit set. I am proposing the following changes: 1. Add PT_GNU_PROPERTY segment type: # define PT_GNU_PROPERTY (PT_LOOS + 0x474e553) which covers .note.gnu.property section. 2. Remove GNU_PROPERTY_X86_UINT32_VALID. bfd/ PR ld/23900 * elf.c (get_program_header_size): Add a PT_GNU_PROPERTY segment for NOTE_GNU_PROPERTY_SECTION_NAME.

A zero sh_link section is deliberately chosen for such a section (see PR10337 and PR23850). So this patch disables the SHT_REL* sh_link warning. I've also removed the .rel.dyn/.rela.dyn section name test to disable the sh_info warning for SHT_REL* sections. While relocation sections in an executable need not specify the section they relocate (the relocation sh_offset field is an address, not a section offset), that isn't true in a relocatable file where sh_offset is relative to a section. If .rela.dyn happens to exist in an ET_REL object it must specify a valid section. * readelf.c (process_section_headers): Don't warn on a zero sh_info or sh_link for any reloc section in an executable or shared library. Do warn for .rel.dyn/.rela.dyn in ET_REL.

2018-08-27x86: Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bitH.J. Lu1-8/+28
Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only relocatable objects which don't contain any instructions, linker shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging GNU_PROPERTY_X86_XXX bits. Otherwise, linker output doesn't contain GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs. This patch keeps the GNU_PROPERTY_X86_UINT32_VALID bit and updates readelf to print "<None>" if GNU_PROPERTY_X86_XXX property only has the GNU_PROPERTY_X86_UINT32_VALID bit. bfd/ * elfxx-x86.c (_bfd_x86_elf_parse_gnu_properties): Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bit. binutils/ * readelf.c (decode_x86_isa): Print <None> if bitmask only contains the GNU_PROPERTY_X86_UINT32_VALID bit.

2018-08-24x86: Update GNU_PROPERTY_X86_XXX macrosH.J. Lu1-38/+237
This patch updates GNU_PROPERTY_X86_XXX macros: 1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property. A bit is set if it is set in all relocatable inputs: #define GNU_PROPERTY_X86_UINT32_AND_LO 0xc0000002 #define GNU_PROPERTY_X86_UINT32_AND_HI 0xc0007fff 2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property. A bit is set if it is set in any relocatable inputs: #define GNU_PROPERTY_X86_UINT32_OR_LO 0xc0008000 #define GNU_PROPERTY_X86_UINT32_OR_HI 0xc000ffff 3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property. A bit is set if it is set in any relocatable inputs and the property is present in all relocatable inputs: #define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000 #define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff 4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED and GNU_PROPERTY_X86_FEATURE_2_XXX bits. GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.

2018-07-30Add support for the C_SKY series of processors.Andrew Jenner1-0/+9
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc. This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about. bfd * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add C-SKY.
