From 755b748fd9fbee8cad2e55535d23298e8ac76b15 Mon Sep 17 00:00:00 2001 From: Tamar Christina Date: Wed, 3 Oct 2018 18:37:07 +0100 Subject: AArch64: Refactor verifiers to make more general. The current verifiers only take an instruction description and encoded value as arguments. This was enough when the verifiers only needed to do simple checking but it's insufficient for the purposes of validating instruction sequences. This patch adds the required arguments and also a flag to allow a verifier to distinguish between whether it's being run during encoding or decoding. It also allows for errors and warnings to be returned by a verifier instead of a simple pass/fail. include/ * opcode/aarch64.h (struct aarch64_opcode): Expand verifiers to take more arguments. opcodes/ * aarch64-dis.c (aarch64_opcode_decode): Update verifier call. * aarch64-opc.c (verify_ldpsw): Update arguments. --- opcodes/ChangeLog | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'opcodes/ChangeLog') diff --git a/opcodes/ChangeLog b/opcodes/ChangeLog index 1da4e80..aae5459 100644 --- a/opcodes/ChangeLog +++ b/opcodes/ChangeLog @@ -1,5 +1,10 @@ 2018-10-03 Tamar Christina + * aarch64-dis.c (aarch64_opcode_decode): Update verifier call. + * aarch64-opc.c (verify_ldpsw): Update arguments. + +2018-10-03 Tamar Christina + * aarch64-dis.c (ERR_OK, ERR_UND, ERR_UNP, ERR_NYI): Remove.
