2019-07-01x86: remove ModRM.mod decoding layer from AVX512F VMOVS{S,D}Jan Beulich1-26/+8
Just like their AVX counterparts they can utilize XMVexScalar / EXdVexScalarS / EXqVexScalarS taking care of dropping the middle operand for their memory forms.
2019-06-27i386: Check vector length for scatter/gather prefetch instructionsH.J. Lu1-8/+8
Since not all vector lengths are supported by scatter/gather prefetch instructions, decode them only with supported vector lengths. gas/ PR binutils/24719 * testsuite/gas/i386/disassem.s: Add test for vgatherpf0dps with invalid vector length. * testsuite/gas/i386/x86-64-disassem.s: Likewise. * testsuite/gas/i386/disassem.d: Updated. * testsuite/gas/i386/x86-64-disassem.d: Likewise. opcodes/ PR binutils/24719 * i386-dis-evex-len.h: Add EVEX_LEN_0F38C6_REG_1_PREFIX_2, EVEX_LEN_0F38C6_REG_2_PREFIX_2, EVEX_LEN_0F38C6_REG_5_PREFIX_2, EVEX_LEN_0F38C6_REG_6_PREFIX_2, EVEX_LEN_0F38C7_R_1_P_2_W_0, EVEX_LEN_0F38C7_R_1_P_2_W_1, EVEX_LEN_0F38C7_R_2_P_2_W_0, EVEX_LEN_0F38C7_R_2_P_2_W_1, EVEX_LEN_0F38C7_R_5_P_2_W_0, EVEX_LEN_0F38C7_R_5_P_2_W_1, EVEX_LEN_0F38C7_R_6_P_2_W_0 and EVEX_LEN_0F38C7_R_6_P_2_W_1. * i386-dis-evex-prefix.h: Update PREFIX_EVEX_0F38C6_REG_1, PREFIX_EVEX_0F38C6_REG_2, PREFIX_EVEX_0F38C6_REG_5 and PREFIX_EVEX_0F38C6_REG_6 entries. * i386-dis-evex-w.h: Update EVEX_W_0F38C7_R_1_P_2, EVEX_W_0F38C7_R_2_P_2, EVEX_W_0F38C7_R_5_P_2 and EVEX_W_0F38C7_R_6_P_2 entries. * i386-dis.c: Add EVEX_LEN_0F38C6_REG_1_PREFIX_2, EVEX_LEN_0F38C6_REG_2_PREFIX_2, EVEX_LEN_0F38C6_REG_5_PREFIX_2, EVEX_LEN_0F38C6_REG_6_PREFIX_2, EVEX_LEN_0F38C7_R_1_P_2_W_0, EVEX_LEN_0F38C7_R_1_P_2_W_1, EVEX_LEN_0F38C7_R_2_P_2_W_0, EVEX_LEN_0F38C7_R_2_P_2_W_1, EVEX_LEN_0F38C7_R_5_P_2_W_0, EVEX_LEN_0F38C7_R_5_P_2_W_1, EVEX_LEN_0F38C7_R_6_P_2_W_0 and EVEX_LEN_0F38C7_R_6_P_2_W_1 enums.
2019-06-25x86: drop dqa_modeJan Beulich1-12/+2
I assume this mode was needed when EVEX.W handling wasn't really correct yet for other than 64-bit mode. It's clearly not needed anymore. Its elimination also allows dropping the EVEX.W split of VCVT{,U}SI2SS. (For the record, the dropped mode would have been wrong if used in any table entry not already guaranteeing EVEX.W=1.)
