2018-12-14elf: Add PT_GNU_PROPERTY segment typeH.J. Lu1-3/+1
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.

This lets the live and gcore-created dump tests PASS. I don't know yet what's the reason for those weird 'Unrecognized tag value' warnings with native core dumps is; elfdump -n certainly doesn't show them. However, native core dumps still need quite some work (mostly in bfd) in this and other areas.

2018-08-24x86: Update GNU_PROPERTY_X86_XXX macrosH.J. Lu1-24/+88
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. A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined.

2018-08-24x86: Add GNU_PROPERTY_X86_UINT32_VALIDH.J. Lu1-0/+3
The older linker treats .note.gnu.property section as a generic note and just concatenates all .note.gnu.property sections from the input to the output. On CET-enabled OS, the output of the older linker is marked as CET enabled, but in fact, it is not CET enabled and it crashes on CET-enabled machines.

2018-07-30Add support for the C_SKY series of processors.Andrew Jenner1-0/+5
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.

2017-06-22x86: Support Intel IBT with IBT property and IBT-enable PLTH.J. Lu1-0/+3
To support IBT in Intel Control-flow Enforcement Technology (CET) instructions: https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf #define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002 #define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0) are added to GNU program properties to indicate that all executable sections are compatible with IBT when ENDBR instruction starts each valid target where an indirect branch instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on all relocatable inputs. The followings changes are made to the Procedure Linkage Table (PLT): 1. For 64-bit x86-64, PLT is changed to PLT0: push GOT[1] bnd jmp *GOT[2] nop ... PLTn: endbr64 push namen_reloc_index bnd jmp PLT0 together with the second PLT section: PLTn: endbr64 bnd jmp *GOT[namen_index] nop BND prefix is also added so that IBT-enabled PLT is compatible with MPX. 2. For 32-bit x86-64 (x32) and i386, PLT is changed to PLT0: push GOT[1] jmp *GOT[2] nop ... PLTn: endbr64 # endbr32 for i386. push namen_reloc_index jmp PLT0 together with the second PLT section: PLTn: endbr64 # endbr32 for i386. jmp *GOT[namen_index] nop BND prefix isn't used since MPX isn't supported on x32 and BND registers aren't used in parameter passing on i386. GOT is an array of addresses. Initially, GOT[namen_index] is filled with the address of the ENDBR instruction of the corresponding entry in the first PLT section. The function, namen, is called via the ENDBR instruction in the second PLT entry. GOT[namen_index] is updated to the actual address of the function, namen, at run-time. 2 linker command line options are added: 1. -z ibtplt: Generate IBT-enabled PLT. 2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program properties as well as IBT-enabled PLT. bfd/ * elf32-i386.c (elf_i386_lazy_ibt_plt0_entry): New.

2017-04-04Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXXH.J. Lu1-0/+7
Mark an ALLOC section, which should be placed in special memory area, with SHF_GNU_MBIND. Its sh_info field indicates the special memory type. GNU_MBIND section names start with ".mbind" so that they are placed as orphan sections by linker. All input GNU_MBIND sections with the same sh_type, sh_flags and sh_info are placed in one output GNU_MBIND section. In executable and shared object, create a GNU_MBIND segment for each GNU_MBIND section and its segment type is PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is aligned at page boundary.

2015-02-20S390: Support new vector register sectionsAndreas Arnez1-0/+4
The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15 include the existing 64-bit wide floating point registers. The Linux kernel presents the vector registers as two additional register sets, one for the right halves of v0-v15 and another one for the full registers v16-v31. Thus a new core file may contain two new register note sections, and this patch adds support to binutils for them. bfd/ * elf-bfd.h (elfcore_write_s390_vxrs_low): Add prototype.
