2019-07-19cpu,opcodes,gas: use %r0 and %r6 instead of %a and %ctf in eBPF disassemblerJose E. Marchesi1-4/+4
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. Marchesi1-32/+12
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. Marchesi1-16/+16
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. Marchesi <jose.marchesi@oracle.com> * bpf.cpu (dlsi): ldabs and ldind instructions do not take an explicit 'dst' argument. opcodes/ChangeLog: 2019-07-14 Jose E.

Marchesi <jose.marchesi@oracle.com> * testsuite/gas/bpf/mem.s: Do not use explicit arguments for ldabs and ldind instructions. * testsuite/gas/bpf/mem.d: Updated accordingly. * testsuite/gas/bpf/mem-be.d: Likewise.
