2010-11-30Delete a few no longer needed references to pseudos.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120441 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-29Pseudo-ize Thumb2 jump tables with explicit MC lowering to the rawJim Grosbach
instructions. This simplifies instruction printing and disassembly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120333 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-29Rename t2 TBB and TBH instructions to reference that they encode the jump tableJim Grosbach
data. Next up, pseudo-izing them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120320 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-29Merge System into Support.Michael J. Spencer

2010-11-16Encode the multi-load/store instructions with their respective modes ('ia',Bill Wendling
'db', 'ib', 'da') instead of having that mode as a separate field in the instruction. It's more convenient for the asm parser and much more readable for humans. <rdar://problem/8654088> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119310 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01factor the operand list (and related fields/operations) out of Chris Lattner
CodeGenInstruction into its own helper class. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117893 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-07Allow use of the 16-bit literal move instruction in CMOVs for ARM mode.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115884 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-06Now that VDUPfqf and VDUPfdfare properly pseudos, nuke the special handling.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115841 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-27Fix a comment typo.Bob Wilson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112302 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-11Add a separate ARM instruction format for Saturate instructions.Bob Wilson
(I discovered 2 more copies of the ARM instruction format list, bringing the total to 4!! Two of them were already out of sync. I haven't yet gotten into the disassembler enough to know the best way to fix this, but something needs to be done.) Add support for encoding these instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110754 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-08Changes to ARM tail calls, mostly cosmetic.Dale Johannesen
Add explicit testcases for tail calls within the same module. Duplicate some code to humor those who think .w doesn't apply on ARM. Leave this disabled on Thumb1, and add some comments explaining why it's hard and won't gain much. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107851 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-18An attempt to fix the problem Anton reported withDale Johannesen
ARM tail calls. Don't know if it works, but it doesn't break Darwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106309 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-15Next round of tail call changes. Register used in a tailDale Johannesen
call must not be callee-saved; following x86, add a new regclass to represent this. Also fixes a couple of bugs. Still disabled by default; Thumb doesn't work yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106053 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-03Early implementation of tail call for ARM.Dale Johannesen
A temporary flag -arm-tail-calls defaults to off, so there is no functional change by default. Intrepid users may try this; simple cases work but there are bugs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105413 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20When doing Thumb disassembly, there's no need to consider ↵Johnny Chen
t2ADDrSPi12/t2SUBrSPi12, as their generic counterparts t2ADDri12/t2SUBri12 should suffice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101929 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-09If all the bit positions are not specified; do not decode the instructions.Johnny Chen
We are bound to fail! For proper disassembly, the well-known encoding bits of the instruction must be fully specified. This also removes pseudo instructions from considerations of disassembly, which is a better design and less fragile than the name matchings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100899 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-09Provide versions of the ARM eh_sjlj_setjmp instructions for non-VFP subtargetsBob Wilson
such that the non-VFP versions have no implicit defs of VFP registers. If any callee-saved VFP registers are marked as having been defined, the prologue/epilogue code will try to save and restore them. Radar 7770432. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100892 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-09ARM decoder emitter should print out useful information unconditionally when itJohnny Chen
encounters decoding conflicts, instead of wrapping it inside the DEBUG() macro. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100886 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08Now that Evan Cheng has fixed the coalescer bug (r100804), the workaround codeJohnny Chen
to avoid memcpy() call is no longer necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100811 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08Various MSVC warning fixes about truncated 64 bit shifts and const pointers ↵Benjamin Kramer
passed to free. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100767 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-07Fix typo and correct comment somewhat.Eric Christopher
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100691 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-07Re-enable ARM/Thumb disassembler and add a workaround for a memcpy() call inJohnny Chen
ARMDecoderEmitter.cpp, with FIXME comment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100690 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-03Fix a warning in GCC about a pointless typedef.Chandler Carruth
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100268 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-02Move variable "Bits" declaration/definition into the DEBUG block where its usageJohnny Chen
is expected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100247 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-02Fixed build warning.Johnny Chen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100244 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-02Change from .../Support/DataTypes.h to .../System/DataTypes.h.Johnny Chen
(Fix build failure) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100243 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-02Second try of initial ARM/Thumb disassembler check-in. It consists of a tablgenJohnny Chen
backend (ARMDecoderEmitter) which emits the decoder functions for ARM and Thumb, and the disassembler core which invokes the decoder function and builds up the MCInst based on the decoded Opcode. Reviewed by Chris Latter and Bob Wilson. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100233 91177308-0d34-0410-b5e6-96231b3b80d8
