Craig Topper efd67d4612 Changed register names (and pointer keywords) to be lower case when using Intel X86 assembler syntax. 
Patch by Richard Mitton.

Michael Liao 95d9440348 Add CLAC/STAC instruction encoding/decoding support 
As these two instructions in AVX extension are privileged instructions for
special purpose, it's only expected to be used in inlined assembly.

Jakob Stoklund Olesen 5b535c965e Add a catch-all WriteSystem SchedWrite type. 
This is used for all the expensive system instructions.

Dan Gohman 164fe18cfe Rename @llvm.debugger to @llvm.debugtrap. 
llvm-svn: 156774
 2012-05-14 18:58:10 +00:00
Dan Gohman dfab443ae8 Define a new intrinsic, @llvm.debugger. It will be similar to __builtin_trap(), 
but it generates int3 on x86 instead of ud2.

Kevin Enderby 49e6a0da7e Change the sysexit mnemonic (and sysexitl) to never have the REX.W prefix and 
not depend on In32BitMode.  Use the sysexitq mnemonic for the version with the
REX.W prefix and only allow it only In64BitMode.  rdar://9738584

 2011-10-27 17:40:41 +00:00
Craig Topper 0ae8d4d738 Add X86 INVPCID instruction. Add 32/64-bit predicates to INVEPT, INVVPID, VMREAD, and VMWRITE to remove hack from X86RecognizableInstr. 
llvm-svn: 142117
 2011-10-16 07:05:40 +00:00
Craig Topper d9cfddc5cd Add X86 disassembler support for RDFSBASE, RDGSBASE, WRFSBASE, and WRGSBASE.

Joerg Sonnenberger 91e5662075 Recognize the xstorerng alias for VIA PadLock's xstore instruction.

Chris Lattner fc4fe00a65 fix rdar://8735979 - "int 3" doesn't match to "int3". Unfortunately, 
InstAlias doesn't allow matching immediate operands, so we have to write
C++ code to do this.

llvm-svn: 129223
 2011-04-09 19:41:05 +00:00
Joerg Sonnenberger fc4789da4a Add support for the VIA PadLock instructions.

Rafael Espindola e39062199e Implement xgetbv and xsetbv. 
Patch by Jai Menon.

Kevin Enderby 5e7cb5fc27 Added the x86 instruction ud2b (2nd official undefined instruction).

Andrew Trick edd006c1c3 Reverting r117031 to cleanup valgrind errors. 
It doesn't look like anything is wrong with the checkin,
but the new test cases expose a mem bug in AsmParser.

llvm-svn: 117087
 2010-10-22 03:58:29 +00:00
Kevin Enderby 0138a05557 More tweaks to X86 instructions to allow the 'w' suffix in places it makes 
sense, when the instruction takes the 16-bit ax register or m16 memory
location.  These changes to llvm-mc matches what the darwin assembler allows
for these instructions.  Also added the missing flex (without the wait prefix)
and ud2a as an alias to ud2 (still to add ud2b).

llvm-svn: 117031
 2010-10-21 17:16:46 +00:00
Kevin Enderby 49843c0162 Added a few tweaks to the Intel Descriptor-table support instructions to allow 
word forms and suffixed versions to match the darwin assembler in 32-bit and
64-bit modes.  This is again for use just with assembly source for llvm-mc .

Chris Lattner ae33f5d93b continue moving stuff out to X86InstrSystem.td. Move 
control flow stuff out to X86InstrControl.td.  Move
some compiler pseudo instructions and Pat<> patterns
out to X86InstrCompiler.td
