Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

Fix issues with disassembly of IT instructions involving condition codes other the EQ/NE.  Discovered by roundtrip testing.

Add vvvv support to disassembling of instructions with MRMDestMem and MRMDestReg form. Needed to support mem dest form of vmaskmovps/d. Fixes PR10807.

Improve encoding support for BLX with immediat eoperands, and fix a BLX decoding bug this uncovered.

llvm-svn: 138675

invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons.  We were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts.  Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits.  This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure.

llvm-svn: 138653

Support an extension of ARM asm syntax to allow immediate operands to ADR instructions.  This is helpful for disassembler testing, and indeed exposed a disassembler bug that is also fixed here.

llvm-svn: 138623

Port over additional encoding tests to decoding tests, and fix an operand ordering bug this exposed.

llvm-svn: 138575

Give ATTR_VEX higher priority when generating the disassembler context table. Fixes disassembling of VEX instructions with 'pp'=00. Fixes subset of PR10678.

llvm-svn: 138552

Add TB encoding to VEROALL, VZEROUPPER, and VCVTPS2PD to allow them to be disassembled. Fixes PR10723.

Fix decoding of Thumb2 prefetch instructions, which account for all the remaining Thumb2 decoding failures found by randomized testing so far.

llvm-svn: 138341

Fix two more instances of mis-matched operand names breaking disassembly.  Found by randomized testing.

Provide operand encoding information for half-precision VCVT instructions.  Found by randomized testing.

llvm-svn: 138273

Fix decoding of VMOVSRR and VMOVRRS, which account for the overwhelming majority of decoder crashes detected by randomized testing.
