63401e33cb FCONST{S,D} behaves the same way as FP unary instructions. This is true for both A8 and A9.

fa85eb6237 Fix PR6696 and PR6663
When a frame pointer is not otherwise required, and dynamic stack alignment
is necessary solely due to the spilling of a register with larger alignment
requirements than the default stack alignment, the frame pointer can be both
used as a general purpose register and a frame pointer. That goes poorly, for
obvious reasons. This patch brings back a bit of old logic for identifying
the use of such registers and conservatively reserves the frame pointer
during register allocation in such cases.

For now, implement for X86 only since it's 32-bit linux which is hitting this,
and we want a targeted fix for 2.7. As a follow-on, this will be expanded
to handle other targets, as theoretically the problem could arise elsewhere
as well.

9d563b676c The disassembler impl. of MCDisassembler::getInstruction() was using the pattern
uint32_t insn;
  MemoryObject.readBytes(Address, 4, (uint8_t*)&insn, NULL)

to read 4 bytes of memory contents into a 32-bit uint variable.  This leaves the
interpretation of byte order up to the host machine and causes PPC test cases of
arm-tests, neon-tests, and thumb-tests to fail.  Fixed to use a byte array for
reading the memory contents and shift the bytes into place for the 32-bit uint
variable in the ARM case and 16-bit halfword in the Thumb case.

fddb7667ca Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field.
When a target instruction wants to set target-specific flags, it should simply
set bits in the TSFlags bit vector defined in the Instruction TableGen class.

This works well because TableGen resolves member references late:

class I : Instruction {
  AddrMode AM = AddrModeNone;
  let TSFlags{3-0} = AM.Value;
}

let AM = AddrMode4 in
def ADD : I;

TSFlags gets the expected bits from AddrMode4 in this example.
