cpu/ChangeLog
* bpf.cpu (define-cond-jump-insn): Renamed from djci.
(dcji) New version with support for JMP32
gas/ChangeLog

* testsuite/gas/bpf/jump32.s: New file.
* testsuite/gas/bpf/jump32.d: Likewise.
opcodes/ChangeLog
* bpf-desc.c: Regenerate.
* bpf-desc.h: Likewise.
* bpf-opc.c: Regenerate.
* bpf-opc.h: Likewise.
This patch fixes the neg/neg32 BPF instructions, which have K (=0)
instead of X (=1) in their header source bit, despite operating on
registes.
cpu/ChangeLog:
2020-01-30 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf.cpu (define-alu-insn-un): The unary BPF instructions
(neg and neg32) use OP_SRC_K even if they operate only in
registers.
opcodes/ChangeLog:
2020-01-30 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf-opc.c: Regenerate.
gas/ChangeLog:
2020-01-30 Jose E. Marchesi <jose.marchesi@oracle.com>
* testsuite/gas/bpf/alu.d: Update expected opcode for `neg'.
* testsuite/gas/bpf/alu-be.d: Likewise.
* testsuite/gas/bpf/alu32.d: Likewise for `neg32'.
* testsuite/gas/bpf/alu32-be.d: Likewise.
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. Marchesi <jose.marchesi@oracle.com>
* bpf.cpu (dlabs): New pmacro.
(dlind): Likewise.
opcodes/ChangeLog:
2019-07-15 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf-desc.c: Regenerate.
* bpf-opc.c: Likewise.
* bpf-opc.h: Likewise.
gas/ChangeLog:
2019-07-15 Jose E. Marchesi <jose.marchesi@oracle.com>
* testsuite/gas/bpf/mem.s: ldabs instructions do not take a `src'
register as an argument.
* testsuite/gas/bpf/mem.d: Updated accordingly.
* testsuite/gas/bpf/mem-be.d: Likewise.
* doc/c-bpf.texi (BPF Opcodes): Update to reflect the correct
explicit arguments to ldabs and ldind instructions.
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.
