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.

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.

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.

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.

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

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: 117108
 2010-10-22 17:16:17 +00:00
Owen Anderson 9e44cf2bb2 ARM encodes Q registers as 2xregno (i.e. the number of the D register that corresponds to the lower 
half of the Q register), rather than with just regno.  This allows us to unify the encodings for
a lot of different NEON instrucitons that differ only in whether they have Q or D register operands.

 2010-10-21 20:21:49 +00:00
Bob Wilson 59351844e1 ARM instructions that are both predicated and set the condition codes 
have been printed with the "S" modifier after the predicate.  With ARM's
unified syntax, they are supposed to go in the other order.  We fixed this
for Thumb when we switched to unified syntax but missed changing it for
ARM.  Apparently we don't generate these instructions often because no one
noticed until now.  Thanks to Bill Wendling for the testcase!

Jim Grosbach 7e72ec6626 Refactor the ARM 'setend' instruction pattern. Use a single instruction pattern 
and handle the operand explicitly. Flesh out encoding information. Add an
explicit disassembler testcase for the instruction.

Jim Grosbach d9d31dafda Add custom encoder for the 's' bit denoting whether an ARM arithmetic 
instruction should set the processor status flags or not. Remove the now
unnecessary special handling for the bit from the MCCodeEmitter.

 2010-10-12 23:00:24 +00:00
Bill Wendling 98c29d732d Split out the "size" field from the encoding. The newer documentation has it as 
a separate bit in the coding.
