2019-07-19cpu,opcodes,gas: use %r0 and %r6 instead of %a and %ctf in eBPF disassemblerJose E. Marchesi2-2/+7
This patch changes the eBPF CPU description to prefer the register names %r0 and %r6 instead of %a and %ctx when disassembling. This matches better with the current practice, vs. cBPF. It also updates the GAS tests in order to reflect this change. Tested in a x86_64 host. cpu/ChangeLog: 2019-07-19 Jose E. Marchesi <jose.marchesi@oracle.com> * bpf.cpu (h-gpr): when disassembling, use %r0 and %r6 instead of %a and %ctx. opcodes/ChangeLog: 2019-07-19 Jose E.

2019-07-15cpu,opcodes,gas: fix explicit arguments to eBPF ldabs instructionsJose E. Marchesi2-25/+43
This patch fixes the eBPF CPU description in order to reflect the right explicit arguments passed to the ldabs{b,h,w,dw} instructions, updates the corresponding GAS tests, and updates the BPF section of the GAS manual. cpu/ChangeLog: 2019-07-15 Jose E.

2019-07-14cpu,opcodes,gas: fix arguments to ldabs and ldind eBPF instructionsJose E. Marchesi2-2/+7
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.
