Jim Grosbach ce2bd8d05f Add support for binary encoding of ARM 'adr' instructions referencing constant 
pool entries (LEApcrel pseudo). Ongoing saga of rdar://8542291.

llvm-svn: 120635
 2010-12-02 00:28:45 +00:00
Jim Grosbach dc35e067c1 Refactor LEApcrelJT as a pseudo-instructionlowered to a cannonical ADR 
instruction at MC lowering. Add binary encoding information for the ADR,
including fixup data for the label operand.

Jim Grosbach 7ec3d34553 Pseudo-ize Thumb2 jump tables with explicit MC lowering to the raw 
instructions. This simplifies instruction printing and disassembly.

llvm-svn: 120333
 2010-11-29 22:37:40 +00:00
Jim Grosbach 81af4f9eb1 Rename t2 TBB and TBH instructions to reference that they encode the jump table 
data. Next up, pseudo-izing them.

llvm-svn: 120310
 2010-11-29 19:32:47 +00:00
Jim Grosbach 150b1ad7f8 Switch ARM BR_JTm and BR_JTr instructions to be MC-expanded pseudos. 
llvm-svn: 120303
 2010-11-29 18:37:44 +00:00
Jim Grosbach 08c562bba6 Make the ARM BR_JTadd instruction an explicit pseudo and lower it properly 
in the MC lowering process.

llvm-svn: 119167
 2010-11-15 18:36:48 +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
Chris Lattner de16ca8ecc rename LowerToMCInst -> LowerARMMachineInstrToMCInst. 
llvm-svn: 119071
 2010-11-14 21:00:02 +00:00
Chris Lattner c5afd12557 even more simplifications. ARM MCInstLowering is now just 
a single function instead of a class.  It doesn't need the
complexity that X86 does.

 2010-11-14 20:31:06 +00:00
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

llvm-svn: 118671
 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.

llvm-svn: 118633
 2010-11-09 21:36:17 +00:00
Jim Grosbach 2fd4c37d8b Handle ARM constant pool values that need an explicit reference to the '.' 
pseudo-label. (TLS stuff).

llvm-svn: 118609
 2010-11-09 19:40:22 +00:00
Jim Grosbach 38f8e76e51 Further MCize ARM constant pool values. This allows basic PIC references for 
object file emission.

llvm-svn: 118280
 2010-11-05 17:37:13 +00:00
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.

llvm-svn: 117707
 2010-10-29 20:37:06 +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
Jim Grosbach 5a7c715470 Split ARM::LDRB into LDRBi12 and LDRBrs. Adjust accordingly. Continuing on 
rdar://8477752.

llvm-svn: 117419
 2010-10-27 00:19:44 +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.

Rafael Espindola d9d0c348df Produce the headers directly in the Finish method. This allows us to use 
the existing streamer methods that are endian safe.

llvm-svn: 117275
 2010-10-25 17:50:35 +00:00
Jason W Kim 109ff296c8 Second set of ARM/MC/ELF changes. 
Added ARM specific ELF section types.
Added AttributesSection to ARMElfTargetObject
First step in unifying .cpu assembly tag with ELF/.o
llc now asserts on actual ELF emission on -filetype=obj :-)

llvm-svn: 116257

Jason W Kim bff84d418f First in a sequence of ARM/MC/*ELF* specific work. 
Lifted the EmitRawText calls to ARMAsmPrinter::emitAttribute()
Added ARMAsmPrinter::emitAttributes() (plural s).
TODO:
.cpu attribute needs to be refactored

llvm-svn: 115845
 2010-10-06 21:36:43 +00:00
Jim Grosbach 2c95027258 Now that VDUPfqf and VDUPfdfare properly pseudos, kill the no-longer-needed 
"lane" operand modifier.

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.

Jim Grosbach 05eccf0e44 One Printer to rule them all, One Printer to find them, 
One Printer to lower them all and in the back end bind them.


(Remove option to use the old non-MC asm printer.)

Jim Grosbach 45c83d496f Factor out dbg_value comment printing and teach MC asm printing to use it. 
This should make the arm-linux self-host buildbot happy again.

llvm-svn: 114964
 2010-09-28 17:05:56 +00:00
Jim Grosbach 175d6411c8 Enable the MC-ized ARM asm printer. Passing all local tests, so it's time to 
enable it for real. Leaving the CL option in place to it's easy to disable it
again if (when) testers find something I've missed.
