2010-11-10Simplify and clean up MC symbol lookup for ARM constant pool values. This fixesJim Grosbach
double quoting of ObjC symbol names in constant pool entries. rdar://8652107 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118688 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-10Update ARMConstantPoolValue to not use a modifier string. Use an explicitJim Grosbach
VariantKind marker to indicate the additional information necessary. Update MC to handle the new Kinds. rdar://8647623 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118671 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-09Define the subtarget feature for the architecture version,Bob Wilson
as derived from the target triple. This is important for enabling features that are implied based on the architecture version. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118643 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Do not use MEMBARRIER_MCR for any Thumb code.Bob Wilson
It is only supported for ARM code. Normally Thumb2 code would use DMB instead, but depending on how the compiler is invoked (e.g., -mattr=-db) that might be disabled. This prevents a "cannot select MEMBARRIER_MCR" error in that situation. Radar 8644195 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118642 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Two types of instructions have register lists:Bill Wendling
* LDM, et al, uses a bit mask to indicate the register list. * VLDM, et al, uses a base register plus number. The LDM instructions may be non-contiguous, but the VLDM ones must be contiguous. Those are semantic checks that should be done later in the compiler. Also postpone the creation of the bit mask until it's needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118640 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Change the ARMConstantPoolValue modifier string to an enumeration. This willJim Grosbach
help in MC'izing the references that use them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118633 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-09Add encoder method for ARM load/store shifted register offset operands.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118513 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Add support for a few simple fixups to the ARM Darwin asm backend. This allowsJim Grosbach
constant pool references and global variable refernces to resolve properly for object file generation. For example, int x; void foo(unsigned a, unsigned *p) { p[a] = x; } can now be successfully compiled directly to an (ARM mode) object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118469 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-08Make RegList an ASM operand so that TableGen will generate code for it. This isBill Wendling
an initial implementation and may change once reglists are fully fleshed out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118390 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-07In this context, a reglist is a reg.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118375 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-06Add support for parsing register lists. We can't use a bitfield to keep track ofBill Wendling
the registers, because the register numbers may be much greater than the number of bits available in the machine's register. I extracted the register list verification code out of the actual parsing of the registers. This made checking for errors much easier. It also limits the number of warnings that would be emitted for cascading infractions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118363 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-06Return the base register of a register list for the "getReg()" method. This isBill Wendling
to satisfy the ClassifyOperand method of the Asm matcher without having to add a RegList type to every back-end. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118360 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-06General cleanup:Bill Wendling
- Make ARMOperand a class so that some things are internal to the class. - Reformatting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118357 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-06Add a RegList (register list) object to ARMOperand. It will be used soon to holdBill Wendling
(surprise!) a list of registers. Register lists are consecutive, so we only need to record the start register plus the number of registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118351 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-06Use TryParseRegister() instead of MatchRegisterName(). The former returns -1Bill Wendling
