2021-01-15RISC-V: Comments tidy and improvement.Nelson Chu3-32/+34
The GNU coding standards said the comments should be complete sentences and end with a period and two spaces. But sometimes it should be more cleaner when the comments only include a word or codes. Therefore, I made the following changes after referring to other target/generic codes, * Try to write sentences in comments, must end with a period and two spaces. * End with two spaces without a period for codes/instructions only. * End with one space without a period for a single word/variable only. Besids, also rewrite/remove some comments which are obsolete or too long, and fix indents for comments. bfd/ * elfnn-riscv.c: Comments tidy and improvement. * elfxx-riscv.c: Likewise. * elfxx-riscv.h: Likewise. gas/ * config/tc-riscv.c: Comments tidy and improvement.

Add support for the pause hint instruction, as specified in the Zihintpause extension. The pause instruction is encoded as a special form of a memory fence (which is available as part of the base instruction set). The chosen encoding does not mandate any particular memory ordering and therefore is a true hint. bfd/ * elfxx-riscv.c (riscv_std_z_ext_strtab): Added zihintpause. gas/ * config/tc-riscv.c (riscv_multi_subset_supports): Added INSN_CLASS_ZIHINTPAUSE. * testsuite/gas/riscv/pause.d: New testcase.

2021-01-07RISC-V: Support riscv bitmanip frozen ZBA/ZBB/ZBC instructions (v0.93).Claire Xenia Wolf2-4/+63
In fact rev8/orc.b/zext.h are the aliases of grevi/gorci/pack[w], so we should update them to INSN_ALIAS when we have supported their true instruction in the future. Though we still use the [MATCH|MAKS]_[GREVI|GORCI|PACK|PACKW] to encode them. Besides, the orc.b has the same encoding both in rv32 and rv64, so we just keep one of them in the opcode table.

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.

However, objdump disassembles instructions containing those ignored prefixes by still generating that segment override: 66 66 2e 0f 1f 84 00 data16 nopw %cs:0x0(%rax,%rax,1) 00 00 00 00 Print those segment override prefixes as excessive ones: 66 66 2e 0f 1f 84 00 data16 cs nopw 0x0(%rax,%rax,1) 00 00 00 00 which is what they actually are - they have no effect and the decoding hardware ignores them. gas/ 2020-11-14 Borislav Petkov <bp@suse.de> * testsuite/gas/i386/x86-64-segovr.d: Adjust regexes. * testsuite/gas/i386/x86-64-nops.d: Likewise. * testsuite/gas/i386/x86-64-nops-1.d: Likewise. * testsuite/gas/i386/x86-64-nops-1-g64.d: Likewise. * testsuite/gas/i386/x86-64-nops-1-core2.d: Likewise. * testsuite/gas/i386/x86-64-nops-1-k8.d: Likewise. * testsuite/gas/i386/x86-64-nops-2.d: Likewise. * testsuite/gas/i386/x86-64-nops-3.d: Likewise. * testsuite/gas/i386/x86-64-nops-4.d: Likewise. * testsuite/gas/i386/x86-64-nops-4-core2.d: Likewise. * testsuite/gas/i386/x86-64-nops-4-k8.d: Likewise. * testsuite/gas/i386/x86-64-nops-5.d: Likewise. * testsuite/gas/i386/x86-64-nops-5-k8.d: Likewise. * testsuite/gas/i386/x86-64-nops-7.d: Likewise. * testsuite/gas/i386/x86-64-nop-1.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-1a.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-1b.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-1c.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-1d.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-1g.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-2c.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-6.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-7.d: Likewise. * testsuite/gas/i386/x86-64-align-branch-8.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-1-core2.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-1-k8.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-1.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-2.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-3.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-4-core2.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-4-k8.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-4.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-5-k8.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops-5.d: Likewise. * testsuite/gas/i386/ilp32/x86-64-nops.d:: Likewise. ld/ 2020-11-14 Borislav Petkov <bp@suse.de> * testsuite/ld-x86-64/pe-x86-64-4.od: Adjust regexes. * testsuite/ld-x86-64/tlsld3.dd: Likewise. * testsuite/ld-x86-64/tlsld4.dd: Likewise. opcodes/ 2020-11-14 Borislav Petkov <bp@suse.de> * i386-dis.c (ckprefix): Do not assign active_seg_prefix in 64-bit addressing mode.

2020-11-09aarch64: Update LS64 feature with system registerPrzemyslaw Wirkus2-0/+6
This patch: + Adds new ACCDATA_EL1 (Accelerator Data) system register, see [0]. + Adds LS64 instruction tests. + Update LS64 feature test with new register. + Fix comment for AARCH64_OPND_Rt_LS64. [0] https://developer.arm.com/docs/ddi0595/i/aarch64-system-registers/accdata_el1 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).
2020-11-09aarch64: Limit Rt register number for LS64 load/store instructionsPrzemyslaw Wirkus6-168/+183
Atomic 64-byte load/store instructions limit Rt register number to values matching below condition (register <Xt> number must be even and <= 22): if Rt<4:3> == '11' || Rt<0> == '1' then UNDEFINED; This patch adds check if Rt fulfills above requirement. For more details regarding atomic 64-byte load/store instruction for Armv8.7 please refer to Arm A64 Instruction set documentation for Armv8-A architecture profile, see document page 157 for load instruction, and pages 414-418 for store instructions of [0].

2020-11-04aarch64: Update feature RAS system registersPrzemyslaw Wirkus2-0/+10
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].

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.

2020-10-28aarch64: Add DSB instruction Armv8.7-a variantPrzemyslaw Wirkus10-1455/+1513
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.
