Jim Grosbach 0bfb4d5043 The ARM AsmMatcher needs to know that the CCOut operand is a register value, 
not an immediate. It stores either ARM::CPSR or reg0.

 2010-12-06 18:21:12 +00:00
Bill Wendling 87240d4b9c Add a post encoder method to the VFP instructions to convert them to the Thumb2 
encoding if we're in that mode.

Bill Wendling a9e3df7aa0 * Add support for encoding t_addrmode_s2 and t_addrmode_s1. They are the same as 
t_addrmode_s4, but with a different scaling factor.

* Encode the Thumb1 load and store instructions. This involved a bit of
  refactoring (hi, Chris! :-). Some of the patterns became dead afterwards and
  were removed.

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

 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.

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.

 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.

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

Chris Lattner 63274cbc5d add fields to the .td files unconditionally, simplifying tblgen a bit.

 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

to splitting the load/store pre/post indexed instructions into [r, r] and
[r, imm] forms.

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.
