Fold the code with that setting the "byte" operand flag to force an error (no insn at all accepts both "byte ptr" and tbyte ptr" operands, except for AnySize ones where the two (conflicting) recorded types don't matter (operand_size_match() doesn't call match_operand_size() in this case). --- diff --git a/gas/ChangeLog b/gas/ChangeLog index 70aff3d932..54ede43421 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,9 @@ +2019-12-09 Jan Beulich + + * config/tc-i386-intel.c (i386_intel_operand): Set "byte" + attribute suffix instead of suffix uniformly for insns not + possibly accepting "tbyte ptr" explicitly. + 2019-12-09 Jan Beulich * config/tc-i386-intel.c (i386_intel_operand): Don't set suffix diff --git a/gas/config/tc-i386-intel.c b/gas/config/tc-i386-intel.c index bf8d9bedb2..7d0a5b8d85 100644 --- a/gas/config/tc-i386-intel.c +++ b/gas/config/tc-i386-intel.c @@ -691,17 +691,12 @@ i386_intel_operand (char *operand_string, int got_a_float) i.types[this_operand].bitfield.tbyte = 1; if (got_a_float == 1) suffix = LONG_DOUBLE_MNEM_SUFFIX; - else if (current_templates->start->operand_types[0].bitfield.fword - || current_templates->start->operand_types[0].bitfield.tbyte) - { - /* l[defgs]s, [ls][gi]dt */ - if (flag_code == CODE_64BIT) - suffix = QWORD_MNEM_SUFFIX; - else - i.types[this_operand].bitfield.byte = 1; /* cause an error */ - } + else if ((current_templates->start->operand_types[0].bitfield.fword + || current_templates->start->operand_types[0].bitfield.tbyte) + && flag_code == CODE_64BIT) + suffix = QWORD_MNEM_SUFFIX; /* l[fgs]s, [ls][gi]dt */ else - suffix = BYTE_MNEM_SUFFIX; /* so it will cause an error */ + i.types[this_operand].bitfield.byte = 1; /* cause an error */ break; case O_oword_ptr:
