2018-12-19x86: Properly handle PLT expression in directiveH.J. Lu8-3/+34
For PLT expressions, we should subtract the PLT relocation size only for jump instructions.

2018-12-14elf: Add PT_GNU_PROPERTY segment typeH.J. Lu3-3/+9
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.

2018-12-06PowerPC @l, @h and @ha warnings, plus VLE e_liAlan Modra2-33/+61
This patch started off just adding the warnings in tc-ppc.c about incorrect usage of @l, @h and @ha in instructions that don't have 16-bit D-form fields. That unfortunately showed up three warnings in ld/testsuite/ld-powerpc/vle-multiseg.s on instructions like e_li r3, IV_table@l+0x00 which was being assembled to 8: 70 60 00 00 e_li r3,0 a: R_PPC_ADDR16_LO IV_table The ADDR16_LO reloc is of course completely bogus on e_li, which has a split 20-bit signed integer field in bits 0x1f7fff, the low 11 bit in 0x7ff, the next 5 bits in 0x1f0000, and the high 4 bits in 0x7800. Applying an ADDR16_LO reloc to the instruction potentially changes the e_li instruction to e_add2i., e_add2is, e_cmp16i, e_mull2i, e_cmpl16i, e_cmph16i, e_cmphl16i, e_or2i, e_and2i., e_or2is, e_lis, e_and2is, or some invalid encodings. Now there is a relocation that suits e_li, R_PPC_VLE_ADDR20, which was added 2017-09-05 but I can't see code in gas to generate the relocation. In any case, VLE_ADDR20 probably doesn't have the correct semantics for @l since ideally you'd want an @l to pair with @h or @ha to generate a 32-bit constant. Thus @l should only produce a 16-bit value, I think. So we need some more relocations to handle e_li it seems, or as I do in this patch, modify the behaviour of existing relocations when applied to e_li instructions. include/ * opcode/ppc.h (E_OPCODE_MASK, E_LI_MASK, E_LI_INSN): Define. bfd/ * elf32-ppc.c (ppc_elf_howto_raw <R_PPC_VLE_ADDR20>): Correct mask and shift value.

2018-12-06opcodes/riscv: Hide '.L0 ' fake symbolsAndrew Burgess2-2/+8

2018-12-05[aarch64] Add support for pointer authentication B keySam Tebbs7-16/+150
Armv8.3-A has another key used in pointer authentication called the B-key (other than the A-key that is already supported). In order for stack unwinders to work it is necessary to be able to identify frames that have been signed with the B-key rather than the A-key and it was felt that keeping this as an augmentation character in the CIE was the best bet. The DWARF extensions for ARM therefore propose to add a new augmentation character 'B' to the CIE augmentation string and the corresponding cfi directive ".cfi_b_key_frame". I've made the relevant changes to GAS and LD to add support for B-key unwinding, which required modifying LD to check for 'B' in the augmentation string, adding the ".cfi_b_key_frame" directive to GAS and adding a "pauth_key" field to GAS's fde_entry and cie_entry structs. The pointer authentication instructions will behave as NOPs on architectures that don't support them, and so a check for the architecture being assembled for is not necessary since there will be no behavioural difference between augmentation strings with and without the 'B' character on such architectures. 2018-12-05 Sam Tebbs <sam.tebbs@arm.com> bfd/ * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Add check for 'B'. gas/ * dw2gencfi.c (struct cie_entry): Add tc_cie_entry_extras invocation.

2018-12-01PR23938, should not free memory alloced in obstack by free()Alan Modra8-44/+67
This removes ineffectual and wrong code caching section names in gas/stabs.c. Code like seg = subseg_new (name, 0); ... if (seg->name == name) seg->name = xstrdup (name); with the idea of being able to unconditionally free "name" later no longer works. "name" is referenced by the section hash table as well as in the section->name field. It would be possible to use "bfd_rename_section (stdoutput, seg, xstrdup (name))", but instead I opted for a fairly straight-forward approach of adding extra parameters to two functions to indicate section name strings should be freed if possible.

2018-11-30GAS/MIPS: Add `-mfix-r5900' option for the R5900 short loop erratumFredrik Noring9-1/+161
`-march=r5900' already enables the R5900 short loop workaround. However, the R5900 ISA and most other MIPS ISAs are mutually exclusive since R5900-specific instructions are generated as well. The `-mfix-r5900' option can be used in combination with e.g. `-mips2' or `-mips3' to generate generic MIPS binaries that also work with the R5900 target. This change has been tested with `make RUNTESTFLAGS=mips.exp check-gas' for the targets `mipsr5900el-unknown-linux-gnu', `mipsr5900el-elf' and `mips3-unknown-linux-gnu'. gas/ * config/tc-mips.c (mips_fix_r5900, mips_fix_r5900_explicit): New variables.

2018-11-27[ARM] Update knowledge of bfd architecturesThomas Preud'homme150-0/+1145
Commit c0c468d562649df0f695737262b6230b7a56a4bb updated bfd's knowledge of Arm architectures to Armv5TEJ and later but missed the list of CPUs recognized by objdump -d -m<cpu>. .note.gnu.arm.ident related code is intentionally not updated as build attributes are a better mechanism to express the ISA in a file. However this patch adds tests for the existing code since no existing testcase cover those codepaths. Since I've only ever managed for bfd_arm_get_mach_from_notes () to have an effect by using objcopy on a file with a note but no Arm build attribute, the tests make use of both objcopy actions supported by run_dump_test which requires to have a ld line as well. Note that the CPU list in bfd/cpu-arm.c was simply copied over from GAS' CPU list but sorted alphabetically as already done for existing entries. 2018-11-27 Thomas Preud'homme <thomas.preudhomme@linaro.org> bfd/ * cpu-arm.c (processors): Add processors known to GAS but missing here and reindent.

2018-11-09PowerPC, don't use bfd reloc howto in md_assembleAlan Modra2-11/+255
We support source like the following .data .quad x-. .space 8 x: where at the time the .quad line is assembled, x is unknown so a fixup is emitted for later evaluation. This is supported for data even when the target may not have relocations for the expression, for example, 32-bit powerpc targets lack a 64-bit reloc. As long as the fixup resolves at assembly time, gas is happy. The idea of this patch is to support fixups that resolve at assembly time for instructions too, even when the target might lack the necessary relocations (and thus no howto). * config/tc-ppc.c (fixup_size): New function. (md_assemble): Use it to derive size and pcrel directly from fixup reloc type.

VCVT between f16 and f32 is an Advanced SIMD instruction. Not all the VCVT alternatives need neon, hence the check for neon is in the encode function. The check on neon for VCVT.f16.f32 (and vice versa) is missing. vshcmd: > echo 'vcvt.f16.f32 d1, q1' | gas/as-new -mfpu=vfpxd -march=armv8.5-a - testdir [15:59:10] $ Also, the handling of the condition code behaves differently to other SIMD instructions -- no error message is produced when assembling an instruction with a condition code suffix despite the arm encoding not allowing a condition code. (n.b. the actual binary produced is independent of the suffix). The instruction should be treated similarly to VSUBL that has the same caveat of "must be unconditional" describing the {<c>} symbol. vcvt half-precision to single precision found in F6.1.58 in the ARM Architecture Reference Manual issue C.a, vsubl found in F6.1.240 in the ARM Architecture Reference Manual issue C.a 2018-11-06 Matthew Malcomson <matthew.malcomson@arm.com> * config/tc-arm.c (do_neon_cvt_1): Add check for neon and condition codes to half-precision conversion. * testsuite/gas/arm/neon-cond-bad-inc.s: Check vcvteq disallowed. * testsuite/gas/arm/neon-cond-bad.l: Likewise. * testsuite/gas/arm/neon-cond-bad_t2.d: Check vcvteq allowed in IT block. * testsuite/gas/arm/vfp-bad.l: Ensure vcvt doesn't work without neon. * testsuite/gas/arm/vfp-bad.s: Likewise.
2018-11-06PowerPC instruction mask checksAlan Modra2-14/+29
The instruction mask bits should never overlap any of the operands, nor should operand bits overlap, but some operands weren't checked. This patch arranges to check the omitted operands, using a mask returned by the operand->insert function. Some tweaking of various insert functions is needed to support this: The error case must set field bits. Since I was looking at the insert functions, I tidied some dead code and simplified some of the powerpc_operands entries. gas/ * config/tc-ppc.c (insn_validate): Don't ignore mask in PPC_OPSHIFT_INV case. Call the insert function to calculate a mask. opcodes/ * ppc-opc.c (insert_arx, insert_ary, insert_rx, insert_ry, insert_ls), (insert_evuimm1_ex0, insert_evuimm2_ex0, insert_evuimm4_ex0), (insert_evuimm8_ex0, insert_evuimm_lt8, insert_evuimm_lt16), (insert_rD_rS_even, insert_off_lsp, insert_off_spe2, insert_Ddd): Don't return zero on error, insert mask bits instead. (insert_sd4h, extract_sd4h, insert_sd4w, extract_sd4w): Delete. (insert_sh6, extract_sh6): Delete dead code. (insert_sprbat, insert_sprg): Use unsigned comparisions. (powerpc_operands <OIMM>): Set shift count rather than using PPC_OPSHIFT_INV. <SE_SDH, SE_SDW>: Likewise. Don't use insert/extract functions.
2018-11-06PowerPC instruction operand flag validationAlan Modra2-0/+14
This adds another check that might have saved me a little time recently if it had been present. * config/tc-ppc.c (insn_validate): Check that optional operands are not followed by non-optional operands.
2018-11-06x86: correctly handle VPBROADCASTD with EVEX.W set outside of 64-bit modeJan Beulich4-0/+10
For the flavor having a GPR operand EVEX.W is ignored outside of 64-bit mode. The mnemonic should therefore not be VPBROADCASTQ.
2018-11-06x86: correctly handle VMOVD with EVEX.W set outside of 64-bit modeJan Beulich4-0/+20
For the flavors having a GPR operand EVEX.W is ignored outside of 64-bit mode. The mnemonic should therefore not be KMOVQ, the GPR operand should not name a non-existing 64-bit register, just like is already the case for the AVX counterparts, and the Disp8 scaling factor should be 4 rather than 8.
2018-11-06x86: correctly handle KMOVD with VEX.W set outside of 64-bit modeJan Beulich3-0/+9
For the flavors having a GPR operand VEX.W is ignored outside of 64-bit mode. The mnemonic should therefore not be KMOVQ.
2018-11-06x86: adjust {,E}VEX.W handling for PEXTR* / PINSR*Jan Beulich8-0/+60
PEXTR{B,W} and PINSR{B,W}, just like for AVX512BW, are WIG, no matter that the SDM uses a nonstandard description of that fact. PEXTRD, even with EVEX.W set, ignores that bit outside of 64-bit mode, just like its AVX counterpart.
2018-11-06x86: adjust {,E}VEX.W handling outside of 64-bit modeJan Beulich13-31/+241
Many VEX-/EVEX-encoded instructions accessing GPRs become WIG outside of 64-bit mode. The respective templates should specify neither VexWIG nor VexW0, but instead the setting of the bit should be determined from - REX.W in 64-bit mode, - the setting established through -mvexwig= / -mevexwig= otherwise. This implies that the evex-wig2 testcase needs to go away, as being wrong altogether. A few test additions desirable here will only happen in later patches, as the disassembler needs adjustments first. Once again SSE2AVX templates are left alone, for it being unclear what the behavior there should be.
2018-11-06x86: fix various non-LIG templatesJan Beulich10-0/+433
Quite a few templates were marked LIG while really the insns aren't. Introduce descriptive shorthands once again, instead of continuing to use the less legible original forms.
2018-11-06x86: allow {store} to select alternative {,}PEXTRW encodingJan Beulich5-2/+51
The 0F C5 encoding is indeed a load type one (just that memory operands are not permitted), while the 0F 3A 15 encoding is obviously a store. Allow the pseudo prefixes to be used to select between them. Also move (without any change) the secondary AVX512BW templates next to the primary one.
2018-11-06x86: add more VexWIGJan Beulich9-18/+70
Commits 6865c0435a ("x86: Support VEX/EVEX WIG encoding") and 6fa52824c3 ("x86: Replace VexW=3 with VexWIG") omitted quite a few templates, oddly enough in some cases despite testcases getting added (which then were recorded with wrong expected output). Also adjust VPMAXUB's attributes in the AVX512BW case to match ordering of that of neighboring templates. For the moment SSE2AVX templates are left alone, as it isn't clear whether they were intentionally left untouched by the original commits (the descriptions don't say either way). In this context I question the decision in commit 0375113302 ("x86: Add -mvexwig=[0|1] option to assembler") to move the logic to determine the value of the W bit ahead of the decision whether to use 2-byte VEX: While I can see this as one possible interpretation of -mvexwig=, the other alternative (setting the value of the bit only if it actually exists in the encoding) looks as reasonable to me, and perhaps even more in line with us generally trying to pick the shortest encoding.
