Andreas Arnez	9811697376	PR26279 Work around maybe-uninitialized warning in s390-mkopc.c In s390-mkopc.c, the function insertExpandedMnemonic() searches for the first occurrence of '' or '$' in the given mnemonic, and, if a match is found, chooses an extension table using a switch() on that character. The switch statement contains a default case that prints an error message and does not set the extension table. Although this case cannot occur, some GCC versions obviously conclude that the extension table might have been left uninitialized after the switch statement and consequently emit maybe-uninitialized warnings for the variables 'ext_table' and 'ext_table_length'. Circumvent the warning by handling the unreachable default case with abort(). opcodes/ s390-mkopc.c (insertExpandedMnemonic): Handle unreachable default case with abort() instead of printing an error message and continuing, to avoid a maybe-uninitialized warning.	6 years ago

Jan Beulich	bf4ba07ca6	Revert "x86: Don't display eiz with no scale" This reverts commit `04c662e2b6`. In my underlying suggestion I neglected the fact that in those cases (,%eiz,1) is the only visible indication that 32-bit addressing is in effect.	6 years ago

Jan Beulich	c3f5525ff1	x86: make PUSH/POP disassembly uniform Irrespective of their encoding the resulting output should look the same. Therefore wire the handling of PUSH/POP with GPR operands encoded in the main opcode byte to the same logic used for other operands. This frees up yet another macro character.	6 years ago
Jan Beulich	36938cabf0	x86: avoid attaching suffixes to unambiguous insns "Unambiguous" is is in particular taking as reference the assembler, which also accepts certain insns - despite them allowing for varying operand size, and hence in principle being ambiguous - without any suffix. For example, from the very beginning of the life of x86-64 I had trouble understanding why a plain and simple RET had to be printed as RETQ. In case someone really used the 16-bit form, RETW disambiguates the two quite fine.	6 years ago

Claudiu Zissulescu	570b0ed6d5	arc: Detect usage of illegal double register pairs ARC can use odd-even double register pairs in some selected instructions.

Jan Beulich	bfbd943845	x86/Intel: debug registers are named DRn %db<n> is an AT&T invention; the Intel documentation and MASM have only ever specified DRn (in line with CRn and TRn). (In principle gas also shouldn't accept the names in Intel mode, but at least for now I've kept things as they are. Perhaps as a first step this should just be warned about.)	6 years ago
Jan Beulich	78467458dd	x86: drop Rm and the 'L' macro Rm (and hence OP_R()) can be dropped by making 'Z' force modrm.mod to 3 (for OP_E()) instead of ignoring it. While at it move 'Z' handling to its designated place (after 'Y'; 'W' handling will be moved by a later change). Moves to/from TRn are illegal in 64-bit mode and thus get converted to honor this at the same time (also getting them in line with moves to/from CRn/DRn ModRM.mod handling wise). This then also frees up the L macro.	6 years ago
Jan Beulich	464d2b6568	x86: drop Rdq, Rd, and MaskR Rdq, Rd, and MaskR can be replaced by Edq, Ed / Rm, and MaskE respectively, as OP_R() doesn't enforce ModRM.mod == 3, and hence where MOD matters but hasn't been decoded yet it needs to be anyway. (The case of converting to Rm is temporary until a subsequent change.)	6 years ago
Jan Beulich	035e7389dd	x86: simplify decode of opcodes valid only without any (embedded) prefix In this case there's no need to go through prefix_table[] at all - the .prefix_requirement == PREFIX_OPCODE machinery takes care of this case already. A couple of further adjustments are needed though: - Gv / Ev and alike then can't be used (needs to be Gdq / Edq instead), - dq_mode and friends shouldn't lead to PREFIX_DATA getting set in used_prefixes.	6 years ago

Jan Beulich	7531c61332	x86: simplify decode of opcodes valid with (embedded) 66 prefix only The only valid (embedded or explicit) prefix being the data size one (which is a fairly common pattern), avoid going through prefix_table[]. Instead extend the "required prefix" logic to also handle PREFIX_DATA alone in a table entry, now used to identify this case. This requires moving the (adjusted) ->prefix_requirement logic ahead of the printing of stray prefixes, as the latter needs to observe the new setting of PREFIX_DATA in used_prefixes. Also add PREFIX_OPCODE on related entries when previously there was mistakenly no decode step through prefix_table[].	6 years ago
Jan Beulich	17d3c7eccd	x86: drop further EVEX table entries that can be served by VEX ones A few cases were missed by `6df22cf64c` ("x86: drop EVEX table entries that can be served by VEX ones").	6 years ago
Jan Beulich	41f5efc685	x86: drop need_vex_reg It was quite odd for the prior operand handling to have to clear this flag for the actual operand handling to print nothing. Have the actual operand handling determine whether the operand is actually present. With this {d,q}_scalar_swap_mode become unused and hence also get dropped.	6 years ago
Jan Beulich	89e65d17e3	x86: drop Vex128 and Vex256 These are only used when VEX.L or EVEX.L'L have already been decoded, and hence the "normal" length dependent name determination is quite fine. Adjust a few enumerators to make clear that vex_len_table[] has been consulted; be consistent and do so for all f128 and i128 insns in one go.	6 years ago
