Jim Grosbach 51fdc47a11 ARMPseudoInst instructions should default to being considered a single 4-byte 
instruction. Any that may be expanded otherwise by MC lowering should
override this value. rdar://8683274

llvm-svn: 119713
 2010-11-18 18:01:40 +00:00
Jim Grosbach a74c7ccd59 ARM PseudoInst instructions don't need or use an assembler string. Get rid of 
the operand to the pattern.

llvm-svn: 119607
 2010-11-18 01:38:26 +00:00
Jim Grosbach 19be1fbca1 Add FIXME. 
llvm-svn: 119603
 2010-11-18 01:20:48 +00:00
Jim Grosbach cfb66204b7 Refactor the ARM PICADD and PICLDR* instructions to really be pseudos and not 
just pretend to be.

llvm-svn: 119602
 2010-11-18 01:15:56 +00:00
Jim Grosbach 8e7f8df4a2 Refactor a few ARM load instructions to better parameterize things and re-use 
common encoding information.

llvm-svn: 119598
 2010-11-18 00:46:58 +00:00
Jim Grosbach 8839775df6 More ARM encoding bits. LDRH now encodes properly. 
llvm-svn: 119529
 2010-11-17 18:11:11 +00:00
Bill Wendling 345b48fcbd Add binary emission stuff for VLDM/VSTM. This reuses the 
"getRegisterListOpValue" logic. If the registers are double or single precision,
the value returned is suitable for VLDM/VSTM.

llvm-svn: 119435
 2010-11-17 00:45:23 +00:00
Bill Wendling 3bd60eff26 - Remove dead patterns. 
- Add encodings to the *LDMIA_RET instrs. Probably not needed...

llvm-svn: 119323
 2010-11-16 02:08:45 +00:00
Jim Grosbach 38b469effd ARM LDR_PRE/LDR_POST/STR_PRE/STR_POST (and the *B counterparts) binary encoding. 
llvm-svn: 119180
 2010-11-15 20:47:07 +00:00
Chris Lattner 63274cbc5d add fields to the .td files unconditionally, simplifying tblgen a bit. 
Switch the ARM backend to use 'let' instead of 'set' with this change.

llvm-svn: 119120
 2010-11-15 05:19:05 +00:00
Bill Wendling e69afc6bb7 Add *_ldst_mult multiclasses to the ARM back-end. These will be used in the 
future to separate out the ia, ib, da, db variants of the load/store multiple
instructions.

llvm-svn: 118995
 2010-11-13 09:09:38 +00:00
Jim Grosbach 2f790749e8 More ARM load/store indexed refactoring. Also fix an incorrect IndexMode 
flag for the LDRT/STRT family instructions as a side effect.

llvm-svn: 118955
 2010-11-13 00:35:48 +00:00
Jim Grosbach 31a7234a47 Refactor to parameterize some ARM load/store encoding patterns. Preparatory 
to splitting the load/store pre/post indexed instructions into [r, r] and
[r, imm] forms.

llvm-svn: 118925
 2010-11-12 21:28:15 +00:00
Evan Cheng 2d59ee34f1 Add some missing isel predicates on def : pat patterns to avoid generating VFP vmla / vmls (they cause stalls). Disabling them in isel is properly not a right solution, I'll look into a proper solution next. 
llvm-svn: 118922
 2010-11-12 20:32:20 +00:00

 2010-11-10 23:12:48 +00:00
Bill Wendling c002463ac4 Add encoding for VSTR. 
llvm-svn: 118220
 2010-11-04 00:59:42 +00:00
Owen Anderson 0ebd1fd594 Revert r118097 to fix buildbots. 
llvm-svn: 118121
 2010-11-02 23:47:29 +00:00
Owen Anderson 7c30390277 Since these fields are not exactly equivalent to the encoded field, rename them to something with semantic meaning. 
llvm-svn: 118097
 2010-11-02 22:41:42 +00:00
Owen Anderson 9f20daf3b4 Factor out a common encoding class for loads and stores with a lane parameter. 
llvm-svn: 118055
 2010-11-02 20:47:39 +00:00
Owen Anderson ad40234eff Add correct NEON encodings for the "multiple single elements" form of vld. 
llvm-svn: 117984
 2010-11-02 00:05:05 +00:00
Bill Wendling 418bd53008 Move the machine operand MC encoding patterns to the parent classes. 
llvm-svn: 117956
 2010-11-01 21:17:06 +00:00
Jim Grosbach fddf36d254 Add 'IsThumb' predicate to patterns marked as 'IsThumb1Only'. The latter gates 
codegen using the patterns; the latter gates the assembler recognizing the
instruction.

llvm-svn: 117931
 2010-11-01 17:08:58 +00:00
Bill Wendling 2623343625 Move instruction encoding bits into the parent class and remove the temporary 
*_Encode classes. These instructions are the only ones which use those classes,
so a subclass isn't necessary.

llvm-svn: 117906
 2010-11-01 06:00:39 +00:00
Chris Lattner 7ff334687d fix the !eq operator in tblgen to return a bit instead of an int. 
Use this to make the X86 and ARM targets set isCodeGenOnly=1 
automatically for their instructions that have Format=Pseudo,
resolving a hack in tblgen.

llvm-svn: 117862
 2010-10-31 19:22:57 +00:00
Jim Grosbach 74ef9e184e Encode the register list operands for ARM mode LDM/STM instructions.

 2010-10-30 00:37:59 +00:00

llvm-svn: 117702
 2010-10-29 20:21:36 +00:00
Jim Grosbach 4e57b52394 ARM mode LDREX*/STREX* binary encodings. 
llvm-svn: 117695
 2010-10-29 19:58:57 +00:00
Jim Grosbach 338de3ee56 Refactor ARM STR/STRB instruction patterns into STR{B}i12 and STR{B}rs, like 
the LDR instructions have. This makes the literal/register forms of the
instructions explicit and allows us to assign scheduling itineraries
appropriately. rdar://8477752

llvm-svn: 117505
 2010-10-27 23:12:14 +00:00
Owen Anderson ed9652f959 Provide correct encodings for the get_lane and set_lane variants of vmov. 
llvm-svn: 117495
 2010-10-27 21:28:09 +00:00
Owen Anderson 40d24a4abf Provide correct NEON encodings for vdup. 
llvm-svn: 117475
 2010-10-27 19:25:54 +00:00
Jim Grosbach 1e4d9a17c2 First part of refactoring ARM addrmode2 (load/store) instructions to be more 
explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

llvm-svn: 117409
 2010-10-26 22:37:02 +00:00
