Jim Grosbach ca21cd749e Simplify and clean up MC symbol lookup for ARM constant pool values. This fixes 
double quoting of ObjC symbol names in constant pool entries.

Jim Grosbach f23b2d9d8d Update ARMConstantPoolValue to not use a modifier string. Use an explicit 
VariantKind marker to indicate the additional information necessary. Update
MC to handle the new Kinds. rdar://8647623

 2010-11-10 03:26:07 +00:00
Jim Grosbach a942ad4222 Change the ARMConstantPoolValue modifier string to an enumeration. This will 
help in MC'izing the references that use them.

Jim Grosbach 2fd4c37d8b Handle ARM constant pool values that need an explicit reference to the '.' 
pseudo-label. (TLS stuff).

Jim Grosbach 38f8e76e51 Further MCize ARM constant pool values. This allows basic PIC references for 
object file emission.

Jim Grosbach 4a0c2d73c3 Convert ARM::MOVi2pieces to a true pseudo-instruction and expand it in 
the ARMExpandPseudos pass rather than during the asm lowering.

llvm-svn: 117714
 2010-10-29 21:35:25 +00:00
Jim Grosbach e477b1ad30 ARM::MOVi32imm is expanded in ARMExpandPseudoInsts, so there's no need to 
handle it in the asm lowering.

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

 2010-10-27 23:12:14 +00:00
Jim Grosbach 5a7c715470 Split ARM::LDRB into LDRBi12 and LDRBrs. Adjust accordingly. Continuing on 
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.

Jim Grosbach 0e854f3d43 Rename the AsmPrinter directory to InstPrinter for those targets that have 
been MC-ized for assembly printing. MSP430 is mostly so, but still has the
asm printer and lowering code in the printer subdir for the moment.

 2010-09-23 18:57:26 +00:00
Jim Grosbach 8503054410 Clean up the 'trap' instruction printing a bit. Non-Darwin assemblers don't 
(yet) recognize the 'trap' mnemonic, so we use .short/.long to emit the
opcode directly. On Darwin, however, we do want the mnemonic for more
readable assembly code and better disassembly.

Adjust the .td file to use the 'trap' mnemonic and handle using the binutils
workaround in the assembly printer. Also tweak the formatting of the opcode
values to make them consistent between the MC printer and the old printer.
