Change the asmprinter to print the comment character before the

get #APP/#NOAPP for free even if they don't use "#" as the comment
character.  This also allows hoisting the darwin stuff up to the

Add 'isCodeGenOnly' bit to Instruction .td records.
 - Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

Simplify this code. The case where one class is GR64RegClass and the
other is a subclass of it is effectively handled by the prior tests.

Add an explicit keyword.

ConstantFolder and NoFolder no longer require their Context members.

now that these are in file-check format, we can merge them together
into one bigger test (which runs faster)

MachineFunctionPass passes.

Don't assume that external global variables are aligned at their preferred
alignment. Only the minimum alignment guaranteed by the ABI may be assumed.

Remove unnecessary throw() specifications; LLVM doesn't use exceptions.

Move ~ARMConstantPoolValue() to the .cpp file to avoid needing to include <cstdlib> in the header.

Remove an unnecessary mutable.

Fix the previous accidental commit. Now shrinking common Thumb2 load / store instructions.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78659 91177308-0d34-0410-b5e6-96231b3b80d8

Fix Thumb2 load / store addressing mode matching code. Do not use so_reg form to
match base only address, i.e. [r] since Thumb2 requires a offset register field.
For those, use [r + imm12] where the immediate is zero.
Note the generated assembly code does not look any different after the patch.
But the bug would have broken the JIT (if there is Thumb2 support) and it can
break later passes which expect the address mode to be well-formed.
