2020-12-14rx-elf FAIL: SHF_GNU_RETAIN sections 27Alan Modra1-10/+10
rx-elf is an odd target with non-standard names for default text, data and bss sections. This patch tweaks a new test to make it pass. * testsuite/gas/elf/section27.s: Reorder .text, .data and .bss so that output section order does not depend on those sections being already created. Use ".section .text" rather than ".text".
2020-12-13x86: Do not dump DS/CS segment overrides for branch hintsBorislav Petkov9-60/+69
I've made all labels normal labels so that there's no confusion between the different targets which is which and I match them in the .d files with .* as Alan suggested.

2020-12-10RISC-V: Add sext.[bh] and zext.[bhw] pseudo instructions.Nelson Chu3-0/+128
https://github.com/riscv/riscv-asm-manual/pull/61 We aleady have sext.w, so just add sext.b, sext.h, zext.b, zext.h and zext.w. In a certain sense, zext.b is not a pseudo - It is an alias of andi. Similarly, sext.b and sext.h are aliases of other rvb instructions, when we enable b extension; But they are pseudos when we just enable rvi. However, this patch does not consider the rvb cases. Besides, zext.w is only valid in rv64. gas/ * config/tc-riscv.c (riscv_ext): New function. Use md_assemblef to expand the zext and sext pseudos, to give them a chance to be expanded into c-ext instructions. (macro): Handle M_ZEXTH, M_ZEXTW, M_SEXTB and M_SEXTH. * testsuite/gas/riscv/ext.s: New testcase. * testsuite/gas/riscv/ext-32.d: Likewise. * testsuite/gas/riscv/ext-64.d: Likewise. include/ * opcode/riscv.h (M_ZEXTH, M_ZEXTW, M_SEXTB, M_SEXTH.): Added. opcodes/ * riscv-opc.c (riscv_opcodes): Add sext.[bh] and zext.[bhw].

2020-12-03IBM Z: Add support for HLASM extended mnemonicsAndreas Krebbel6-52/+157
Add extended mnemonics used in the HLASM assembler. All of them are just aliases for instructions we already support and help when assembling code which was written for the HLASM assembler. The HLASM mnemonics are documented here: https://www.ibm.com/support/knowledgecenter/SSENW6_1.6.0/com.ibm.hlasm.v1r6.asm/asmr1023.pdf See the 'Branching with extended mnemonic codes' chapter. objdump will still print the existing mnemonics with the exception of relative nop branches (i.e. conditional branches with an empty condition code mask). Now we have jnop and jgnop which will be used by objdump when possible. The same change have been applied to the LLVM assembler: https://reviews.llvm.org/D92185 opcodes/ * s390-opc.txt: Add extended mnemonics. gas/ * testsuite/gas/s390/esa-g5.s: Test new extended mnemonics. * testsuite/gas/s390/esa-g5.d: Likewise. * testsuite/gas/s390/esa-z900.s: Likewise. * testsuite/gas/s390/esa-z900.d: Likewise. * testsuite/gas/s390/zarch-z900.s: Likewise. * testsuite/gas/s390/zarch-z900.d: Likewise. ld/ * testsuite/ld-s390/tlsbin_64.dd: The newly added jgnop mnemonic replaces long relative branches with empty condition code mask.
2020-12-01RISC-V: Support to add implicit extensions for G.Nelson Chu3-1/+13
G is a special case, consider the ISA spec github issue as follows, https://github.com/riscv/riscv-isa-manual/issues/575 My understand is that - i, m, a, f and d extensions are not g's implicit extensions, they are g's expansions. The zifencei is the implicit extension of g, and so is zicsr, since it is implicited by f (or i2p1). However, we add the g with the RISCV_UNKNOWN_VERSION to the subset list, and it will not output to the arch string, it is only used to check what implicit extensions are need to be added. bfd/ * elfxx-riscv.c (riscv_parse_add_subset): Allow to add g with RISCV_UNKNOWN_VERSION versions. (riscv_parse_std_ext): Add g to the subset list, we only use it to add the implicit extensions, but won't output it to arch string. (riscv_parse_add_implicit_subsets): Add implicit zicsr and zifencei for g extension. (riscv_arch_str1): Do not output g to the arch string. * elfxx-riscv.h (RISCV_UNKNOWN_VERSION): Moved to include/opcode/riscv.h. gas/ * testsuite/gas/riscv/attribute-10.d: Updated. * testsuite/gas/riscv/march-imply-g.d: New testcase for g. * testsuite/gas/riscv/march-imply-unsupported.d: The zicsr and zifencei are not supported in the ISA spec v2.2, so don't add and output them. include/ * opcode/riscv.h (RISCV_UNKNOWN_VERSION): added.
2020-12-01RISC-V: Support to add implicit extensions.Nelson Chu10-11/+30
We have to parse and add all arch string extensions at first, and then start to add their implicit extensions. That means we can always add arch string extensions at the end of the subset list, but we need to search the right place to add their implicit extensions. For now we follow the following rules to add the implicit extensions, * Add zicsr and zifencei only when the i's version less than 2.1. * Add d, f and zicsr when q is found. * Add f and zicsr when d is found. * Add zicsr when f is found. Besides, we do not add the implicit extensions if they are already added in the subset list, or we cannot find their default versions according to the chosen ISA spec. bfd/ * elfnn-riscv.c (riscv_merge_std_ext): Updated since riscv_lookup_subset is changed. * elfxx-riscv.c (riscv_ext_order): New Array used to compare the extensions' order quickly. (riscv_init_ext_order): New function. Init the riscv_ext_order according to the riscv_supported_std_ext and parse_config[i].class automatically. (riscv_compare_subsets): New function. Similar to the strcmp, but compare the subsets with the specific order. (riscv_lookup_subset): Return TRUE and set `current` to the subset if it is found. Otherwise, return FALSE and set `current` to the place where we should insert the subset. (riscv_add_implicit_subset): New function. Search the list first, and then find the right place to add the implicit_subset. (riscv_parse_add_subset): Since We have to add all arch string extensions first, and then start to add their implicit extensions. We can add arch string extensions in order by the original riscv_add_subset, and then add the implicit subsets by the riscv_add_implicit_subset. Besides, do not add the implicit extensions if we failed to find their default versions. (riscv_parse_std_ext): Updated. (riscv_parse_add_implicit_subsets): New function. Add all implicit extensions according to the arch string extensions. (riscv_parse_subset): Call riscv_init_ext_order and riscv_parse_add_implicit_subsets, before and after parsing the arch string. Remove parts of the ISA conflict checking since the implicit extensions are added. * elfxx-riscv.h (riscv_lookup_subset): Updated. gas/ * config/tc-riscv.c (riscv_subset_supports): Updated. * testsuite/gas/riscv/march-imply-i2p0.d: New testcase.

2020-12-01RISC-V: Improve the version parsing for arch string.Nelson Chu21-22/+32
Keep the riscv_add_subset to do the same thing, and use a new function, riscv_parse_add_subset, to cover most of the things when parsing, including find the default versions for extensions, and check whether the versions are valid. The version 0p0 should be an invalid version, that is the mistake I made before. This patch clarify the version rules as follows, * We accept any version of extensions set by users, except 0p0. * The non-standard x extensions must be set with versions in arch string. * If user don't set the versions, or set 0p0 for the extensions, then try to find the supported versions according to the chosen ISA spec. Otherwise, report errors rather than output 0p0 for them. Besides, we use as_bad rather than as_fatal to report more errors for assembler. bfd/ * elfxx-riscv.c (riscv_lookup_subset): Moved to front. (riscv_add_subset): Likewise. (riscv_release_subset_list): Likewise. (riscv_parse_add_subset): New function. Find and check the versions before adding them by riscv_add_subset. (riscv_parsing_subset_version): Remove use_default_version and change the version type from unsigned to int. Set the versions to RISCV_UNKNOWN_VERSION if we can not find them in the arch string. (riscv_parse_std_ext): Updated. (riscv_parse_prefixed_ext): Updated. Since we use as_bad rather than as_fatal to report more errors, return NULL string if the parsed end_of_version is NULL, too. (riscv_parse_subset): Use a new boolean, no_conflict, to report more errors when we have more than one ISA conflicts. * elfxx-riscv.h (RISCV_DONT_CARE_VERSION): Changed to RISCV_UNKNOWN_VERSION. (riscv_lookup_subset_version): Removed. (riscv_parse_subset_t): Updated. gas/ * config/tc-riscv.c (riscv_get_default_ext_version): Change the version type from unsigned to int.

2020-11-18Support SHF_GNU_RETAIN ELF section flagJozef Lawrynowicz12-5/+156
The SHF_GNU_RETAIN section flag is an extension to the GNU ELF OSABI. It is defined as follows: ========================================================= Section Attribute Flags +-------------------------------------+ | Name | Value | +-------------------------------------+ | SHF_GNU_RETAIN | 0x200000 (1 << 21) | +-------------------------------------+ SHF_GNU_RETAIN The link editor should not garbage collect the section. ========================================================= The .section directive accepts the "R" flag, which indicates SHF_GNU_RETAIN should be applied to the section. There is not a direct mapping of SHF_GNU_RETAIN to the BFD section flag SEC_KEEP.

2020-11-09RISC-V: Update ABI to the elf_flags after parsing elf attributes.Nelson Chu16-0/+124
Originally, if the -mabi option isn't set, then assembler will set the abi according to the architecture string in the riscv_after_parse_args. But we should also check and reset the abi later since the architecture string may be reset by the elf attributes. Therefore, set the abi to the elf_flags in the riscv_after_parse_args seems too early. Besides, we have to set the abi_xlen before assembling any instruction, so it should be safe to call riscv_set_abi_by_arch at the place that we set start_assemble to TRUE. However, one minor case is that we won't call the md_assemble when we are assembling an file without any instruction. It seems that we still need to set the abi in riscv_elf_final_processing, to make sure that abi can be updated according to the elf arch attributes. For the rv32i and most elf toolchains, this patch can fix the mis-matched ABI errors for Run pr26391-5 and Run pr26391-6 testcases. Besides, it also correct the elf header flags of the output objects. Consider the new testcases, mabi-fail-02 and mabi-noabi-attr-[01|02|03], they are failed before applying this patch. But I still get the mis-matched ABI errors for the following toolchains when runnung the riscv-gnu-toolchain regressions, newlib-rv32imafc-ilp32f-[medlow|medany] linux-rv32imac-ilp32-[medlow|medany] linux-rv32imafdc-ilp32-[medlow|medany} linux-rv64imac-lp64-[medlow|medany] linux-rv64imafdc-lp64-[medlow|medany} For the newlib-rv32imafc-ilp32f, although we try to choose the abi according to the elf attributes, we will use FLOAT_ABI_SOFT rather than the FLOAT_ABI_SINGLE for the assmebly file wihtout setting the -mabi, but compiler will set the abi to FLOAT_ABI_SINGLE for the C files. As for the linux toolchains, we also get fails for Run pr26391-5 and Run pr26391-6 testcases. Since the linux toolchain won't generate elf attributes to correct the ISA, and the --with-arch configure option isn't set, assembler will try to set the default arch to rv[32|64]g, which means the FLOAT_ABI_DOUBLE will be choosed, and may be conflict with the abi set by the toolchain. Therefore, I would suggest that it's is more safe to set the --with-arch when building binutils, but it may break some testcases. For example, ld-scripts/fill and ld-scripts/empty-address-2 may be broken when c-ext is set. We might insert R_RISCV_ALIGN to make sure the 4-byte alignment, but the dump result will be a bit different from what the testcase expected. However, this patch only fix the problem - the abi, elf_flags and the instruction, which is generated according to the abi_xlen, are all fixed once the elf attributes are set for most elf toolchains. Other mis-matched ABI problems should be fixed when we always build the binutils with the --with-arch= configure option. gas/ * config/tc-riscv.c (explicit_mabi): New boolean to indicate if the -mabi= option is explictly set. (md_parse_option): Set explicit_mabi to TRUE if -mabi is set. (riscv_set_abi_by_arch): New function. If the -mabi option isn't set, then we set the abi according to the architecture string. Otherwise, check if there are conflicts between architecture and abi setting. (riscv_after_parse_args): Move the abi setting to md_assemble nad riscv_elf_final_processing.

2020-11-04aarch64: Update feature RAS system registersPrzemyslaw Wirkus10-141/+72
This patch: + updates RAS feature system registers with new RAS 1.1 regs. + extends RAS/RAS 1.1 support for all architecture levels of Armv8-A. Please note that early Armv8-A architectures do not officially support RAS extension. Rationale of the patch: To ease development so that user-friendly RAS system registers operands can be used. Certain use cases require developers to enable only more generic architecture (e.g. -march=armv8-a) during system development. Users must use RAS extension registers bearing in mind that system they use must support it. The RAS (Reliability, Availability, Serviceability) extension is a system-level extension that defines a number of system registers. RAS 1.1 (FEAT_RASv1p1) introduces five new system registers: ERXPFGCTL_EL1, ERXPFGCDN_EL1, ERXMISC2_EL1, ERXMISC3_EL1 and ERXPFGF_EL1. For details see [0].

2020-10-28aarch64: Add CSR PDEC instructionPrzemyslaw Wirkus5-0/+23
This patch adds: + New feature +csre to -march command line. + New instruction CSR PDEC associated with CSRE feature. Please note that CSRE system registers were already upstreamed. This patch should finalize CSRE feature implementation. CSRE feature adds CSR PDEC (Decrements Call stack pointer by the size of a Call stack record) instruction. Although this instruction has operand (PDEC) it's instruction's only operand. PDEC forces instruction field Rt to be set to 0b1111. This results in fixed opcode of the instruction. gas/ChangeLog: 2020-10-27 Przemyslaw Wirkus <przemyslaw.wirkus@arm.com> * NEWS: Update docs. * config/tc-aarch64.c (parse_csr_operand): New operand parser.

2020-10-28aarch64: Add DSB instruction Armv8.7-a variantPrzemyslaw Wirkus5-0/+58
This patch adds new variant (nXS) of DSB memory barrier instruction available in Armv8.7-a. New nXS variant has different encoding in comparison with pre Armv8.7-a DSB memory barrier variant thus new instruction and new operand was added. DSB memory nXS barrier variant specifies the limitation on the barrier operation. Allowed values are: DSB SYnXS|#28 DSB ISHnXS|#24 DSB NSHnXS|#20 DSB OSHnXS|#16 Please note that till now, for barriers, barrier operation was encoded in 4-bit unsigned immediate CRm field (in the range 0 to 15). For DSB memory nXS barrier variant, barrier operation is a 5-bit unsigned assembly instruction immediate, encoded in instruction in two bits CRm<3:2>: CRm<3:2> #imm 00 16 01 20 10 24 11 28 This patch extends current AArch64 barrier instructions with above mapping. Notable patch changes include: + New DSB memory barrier variant encoding for Armv8.7-a. + New operand BARRIER_DSB_NXS for above instruction in order to distinguish between existing and new DSB instruction flavour. + New set of DSB nXS barrier options. + New instruction inserter and extractor map between instruction immediate 5-bit value and 2-bit CRm field of the instruction itself (see FLD_CRm_dsb_nxs). + Regeneration of aarch64-[asm|dis|opc]-2.c files. + Test cases to cover new instruction assembling and disassembling.

2020-10-22[PATCH][GAS][AArch64] Define BRBE system registersPrzemyslaw Wirkus5-0/+422
This patch introduces BRBE (Branch Record Buffer Extension) system registers. Note: as this is register only extension we do not want to hide these registers behind -march flag going forward (they should be enabled by default). gas/ChangeLog: 2020-10-08 Przemyslaw Wirkus <przemyslaw.wirkus@arm.com> * NEWS: Docs update. * testsuite/gas/aarch64/brbe-invalid.d: New test. * testsuite/gas/aarch64/brbe-invalid.l: New test. * testsuite/gas/aarch64/brbe-invalid.s: New test. * testsuite/gas/aarch64/brbe.d: New test. * testsuite/gas/aarch64/brbe.s: New test. opcodes/ChangeLog: 2020-10-08 Przemyslaw Wirkus <przemyslaw.wirkus@arm.com> * aarch64-opc.c: Add BRBE system registers.
2020-10-22aarch64: Define CSRE system registersPrzemyslaw Wirkus5-0/+68
This patch introduces CSRE (Call Stack Recorder Extension) system registers. Note: as this is register only extension we do not want to hide these registers behind -march flag going forward (they should be enabled by default). CSRE feature adds CSR PDEC (Decrements Call stack pointer by the size of a Call stack record) instruction. This instruction will be added in a following, separate patch. This change only adds CSRE system registers. gas/ChangeLog: 2020-10-08 Przemyslaw Wirkus <przemyslaw.wirkus@arm.com> * NEWS: Docs update. * testsuite/gas/aarch64/csre-invalid.d: New test. * testsuite/gas/aarch64/csre-invalid.l: New test. * testsuite/gas/aarch64/csre-invalid.s: New test. * testsuite/gas/aarch64/csre.d: New test. * testsuite/gas/aarch64/csre.s: New test. opcodes/ChangeLog: 2020-10-08 Przemyslaw Wirkus <przemyslaw.wirkus@arm.com> * aarch64-opc.c: New CSRE system registers defined.
2020-10-22arm: Fix the wrong error message string for mve vldr/vstr (PR26763).Srinath Parvathaneni3-0/+846
For mve vldr/vstr instructions assembler is throwing wrong error message. Instead of 'Error: syntax error' assembler fails with 'Error: lo register required'. This patch fixes the issue. eg: $ cat x.s .syntax unified .thumb vldrb.s16 q0, r0 Before this patch: $ arm-none-eabi-as x.s -march=armv8.1-m.main+mve -mfloat-abi=hard x.s: Assembler messages: x.s:4: Error: lo register required -- `vldrb.s16 q0,r0' After this patch: $ arm-none-eabi-as x.s -march=armv8.1-m.main+mve -mfloat-abi=hard x.s: Assembler messages: x.s:4: Error: syntax error -- `vldrb.s16 q0,r0' gas/ChangeLog: 2020-10-21 Srinath Parvathaneni <srinath.parvathaneni@arm.com> PR target/26763 * config/tc-arm.c (parse_address_main): Add new MVE addressing mode check. * testsuite/gas/arm/mve-vldr-vstr-bad.d: New test. * testsuite/gas/arm/mve-vldr-vstr-bad.l: Likewise. * testsuite/gas/arm/mve-vldr-vstr-bad.s: Likewise.
