2020-06-04opcodes: discriminate endianness and insn-endianness in CGEN portsJose E. Marchesi2-1/+6
The CGEN support code in opcodes accesses instruction contents using a couple of functions defined in cgen-opc.c: cgen_get_insn_value and cgen_put_insn_value. These functions use the "instruction endianness" in the CPU description to order the read/written bytes. The process of writing an instruction to the object file is: a) cgen_put_insn_value ;; Writes out the opcodes. b) ARCH_cgen_insert_operand insert_normal insert_1 cgen_put_insn_value ;; Writes out the bytes of the ;; operand. Likewise, the process of reading an instruction from the object file is: a) cgen_get_insn_value ;; Reads the opcodes. b) ARCH_cgen_extract_operand extract_normal extract_1 cgen_get_insn_value ;; Reads in the bytes of the ;; operand. As can be seen above, cgen_{get,put}_insn_value are used to both process the instruction opcodes (the constant fields conforming the base instruction) and also the values of the instruction operands, such as immediates. This is problematic for architectures in which the endianness of instructions is different to the endianness of data. An example is BPF, where instructions are always encoded big-endian but the data may be either big or little. This patch changes the cgen_{get,put}_insn_value functions in order to get an extra argument with the endianness to use, and adapts the existin callers to these functions in order to provide cd->endian or cd->insn_endian, whatever appropriate. Callers like extract_1 and insert_1 pass cd->endian (since they are reading/writing operand values) while callers reading/writing the base instruction pass cd->insn_endian instead. A few little adjustments have been needed in some existing CGEN based ports: * The BPF assembler uses cgen_put_insn_value. It has been adapted to pass the new endian argument. * The mep port has code in mep.opc that uses cgen_{get,put}_insn_value. It has been adapted to pass the new endianargument. Ditto for a call in the assembler. Tested with --enable-targets=all. Regested in all supported targets. No regressions. include/ChangeLog: 2020-06-04 Jose E.

2020-05-19or1k: Remove 64-bit support, it's not used and it breaks 32-bit hostsStafford Horne4-110/+16
Reported by Rich Felker when building on 32-bit hosts. Backwards jump negative offsets were not calculated correctly due to improper 32-bit to 64-bit zero-extension. The 64-bit fields are present because we are mixing 32-bit and 64-bit architectures in our cpu descriptions. Removing 64-bit fixes the issue. We don't use 64-bit, there is an architecture spec for 64-bit but no implementations or simulators. My thought is if we need them in the future we should do the proper work to support both 32-bit and 64-bit implementations co-existing then. cpu/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> PR 25184 * or1k.cpu (arch or1k): Remove or64 and or64nd machs.

The eBPF non-generic load instructions ldind{b,h,w,dw} and ldabs{b,h,w,dw} do not take an explicit destination register as an argument. Instead, they put the loaded value in %r0, implicitly. This patch fixes the CPU BPF description to not expect a 'dst' argument in these arguments, regenerates the corresponding files in opcodes, and updates the impacted GAS tests. Tested in a x86-64 host. cpu/ChangeLog: 2019-07-14 Jose E.

2019-06-13cpu/or1k: Update fpu compare symbols to imply set flagStafford Horne2-3/+7
The fpu compare symbols where not including 'sf' in the mnemonic. So instead of `lf-sfeq` (implying set flag if operands are equal) we were having `lf-eq`. This patch adds the 'sf'. This helps with making the generated CGEN documentation consistent and ordered correctly. cpu/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * or1korfpx.cpu (float-setflag-insn-base): Add 'sf' to symbol.

2019-06-13cpu/or1k: Add support for orfp64a32 specStafford Horne6-46/+375
This patch adds support for OpenRISC 64-bit FPU operations on 32-bit cores by using register pairs. The functionality has been added to OpenRISC architecture specification version 1.3 as per architecture proposal 14[0]. For supporting assembly of both 64-bit and 32-bit precision instructions we have defined CGEN_VALIDATE_INSN_SUPPORTED. This allows cgen to use 64-bit bit architecture assembly parsing on 64-bit toolchains and 32-bit architecture assembly parsing on 32-bit toolchains. Without this the assembler has issues parsing register pairs. This patch also contains a few fixes to the symantics for existing OpenRISC single and double precision FPU operations.

This patch adds the new instruction and relocation as per proposal: https://openrisc.io/proposals/ladrp This is to be added to the spec in an upcoming revision. The new instruction l.adrp loads the page offset of the current instruction offset by a 21-bit immediate shifted left 13-bits. This is meant to be used with a 13-bit lower bit page offset. This allows us to free up the got register r16. l.adrp r3, foo l.ori r4, r3, po(foo) l.lbz r5, po(foo)(r3) l.sb po(foo)(r3), r6 The relocations we add are: - BFD_RELOC_OR1K_PLTA26 For PLT jump relocation with PLT entry asm: plta() implemented using l.ardp, meaning no need for r16 (the GOT reg) - BFD_RELOC_OR1K_GOT_PG21 Upper 21-bit Page offset got address asm: got() - BFD_RELOC_OR1K_TLS_GD_PG21 Upper 21-bit Page offset with TLS General asm: tlsgd() Dynamic calculation - BFD_RELOC_OR1K_TLS_LDM_PG21 Upper 21-bit Page offset with TLS local asm: tlsldm() dynamic calculation - BFD_RELOC_OR1K_TLS_IE_PG21 Upper 21-bit Page offset with TLS Initial asm: gottp() Executable calculation - BFD_RELOC_OR1K_PCREL_PG21 Default relocation for disp21 (l.adrp instructions) - BFD_RELOC_OR1K_LO13 low 13-bit page offset relocation asm: po() i.e. mem loads, addi etc - BFD_RELOC_OR1K_SLO13 low 13-bit page offset relocation asm: po() i.e. mem stores, with split immediate - BFD_RELOC_OR1K_GOT_LO13, low 13-bit page offset with GOT calcs asm: gotpo() - BFD_RELOC_OR1K_TLS_GD_LO13 Lower 13-bit offset with TLS GD calcs asm: tlsgdpo() - BFD_RELOC_OR1K_TLS_LDM_LO13 Lower 13-bit offset with TLS LD calcs asm: tlsldmpo() - BFD_RELOC_OR1K_TLS_IE_LO13 Lower 13-bit offset with TLS IE calcs asm: gottppo() bfd/ChangeLog: yyyy-mm-dd Richard Henderson <rth@twiddle.net> * bfd-in2.h: Regenerated. * elf32-or1k.c: (or1k_elf_howto_table): Fix formatting for R_OR1K_PLT26, Add R_OR1K_PCREL_PG21, R_OR1K_GOT_PG21, R_OR1K_TLS_GD_PG21, R_OR1K_TLS_LDM_PG21, R_OR1K_TLS_IE_PG21, R_OR1K_LO13, R_OR1K_GOT_LO13, R_OR1K_TLS_GD_LO13, R_OR1K_TLS_LDM_LO13, R_OR1K_TLS_IE_LO13, R_OR1K_SLO13, R_OR1K_PLTA26.
