From 7d4a7d107ab506c1cecc1870112be57390410248 Mon Sep 17 00:00:00 2001 From: Andreas Arnez Date: Wed, 30 Oct 2013 18:04:32 +0100 Subject: [PATCH] S/390: Disassemble 31-bit binaries with "zarch" opcode set by default Currently the disassembler for s390 (by default) assumes that a 31-bit binary was compiled in "ESA" mode -- and then only disassembles a limited opcode set. The change upgrades the default to the full "zarch" opcode set even for 31-bit binaries. opcodes/ * s390-dis.c (init_disasm): Default to full 'zarch' opcode availability even for 31-bit programs. --- opcodes/ChangeLog | 5 +++++ opcodes/s390-dis.c | 12 +----------- 2 files changed, 6 insertions(+), 11 deletions(-) diff --git a/opcodes/ChangeLog b/opcodes/ChangeLog index bc42de4..c96df92 100644 --- a/opcodes/ChangeLog +++ b/opcodes/ChangeLog @@ -1,3 +1,8 @@ +2013-10-30 Andreas Arnez + + * s390-dis.c (init_disasm): Default to full 'zarch' opcode + availability even for 31-bit programs. + 2013-10-15 Ramana Radhakrishnan * arm-dis.c (neon_opcodes): Adjust print string for vshll. diff --git a/opcodes/s390-dis.c b/opcodes/s390-dis.c index ef73d85..c5397d6 100644 --- a/opcodes/s390-dis.c +++ b/opcodes/s390-dis.c @@ -65,17 +65,7 @@ init_disasm (struct disassemble_info *info) } if (!current_arch_mask) - switch (info->mach) - { - case bfd_mach_s390_31: - current_arch_mask = 1 << S390_OPCODE_ESA; - break; - case bfd_mach_s390_64: - current_arch_mask = 1 << S390_OPCODE_ZARCH; - break; - default: - abort (); - } + current_arch_mask = 1 << S390_OPCODE_ZARCH; init_flag = 1; } -- 2.7.4
