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.

llvm-svn: 138551

llvm-svn: 138441

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.

llvm-svn: 138292

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.

STC2L_POST and STC2L_POST should be handled the same as STCL_POST/LDC_POST for the purposes of decoding all operands except the predicate.
Found by randomized testing.

llvm-svn: 138003

llvm-svn: 138000

Fixes a large class of disassembler crashes found by randomized testing.

llvm-svn: 137995

Fix base register type and canonicallize to the "ldm" spelling rather than
"ldmia." Add diagnostics for incorrect writeback token and out-of-range
registers.

Test commit; adding test for invalid LDRD which was part of the patch for r137647 but seemingly didn't get svn add'ed.

llvm-svn: 137960

llvm-svn: 137954

llvm-svn: 137902

llvm-svn: 137840

Allow the MCDisassembler to return a "soft fail" status code, indicating an instruction that is disassemblable, but invalid.  Only used for ARM UNPREDICTABLE instructions at the moment.
Patch by James Molloy.

llvm-svn: 137830

llvm-svn: 137687

llvm-svn: 137657

Enforce the constraint that Rt must be even on LDRD/STRD instructions in ARM mode.  Update tests to reflect this fact.

llvm-svn: 137636

Fix problems decoding the to/from-lane NEON memory instructions, and add a comprehensive NEON decoding testcase.

llvm-svn: 137635

Fix some remaining issues with decoding ARM-mode memory instructions, and add another batch of tests.

llvm-svn: 137502

Port over the basic ARM encodings test file to a decoding test file.  Greatly increases our test coverage of basic ARM-mode instructions.
