introduce a new recoverable error handling API to LLVMContext
...
and use it in one place in inline asm handling stuff. Before
we'd generate this for an invalid modifier letter:
$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl ${0:Z}'
INLINEASM <es:abc incl ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>
Now we generate this:
$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl ${0:Z}'
asm.c:3:12: note: generated from here
__asm__ ("incl %Z0" : "+r" (X));
^
1 error generated.
This is much better but still admittedly not great ("why" is the operand
invalid??), codegen should try harder with its diagnostics :)

Generalize IVUsers to track arbitrary expressions rather than expressions
...
explicitly split into stride-and-offset pairs. Also, add the
ability to track multiple post-increment loops on the same expression.
This refines the concept of "normalizing" SCEV expressions used for
to post-increment uses, and introduces a dedicated utility routine for
normalizing and denormalizing expressions.
This fixes the expansion of expressions which are post-increment users
of more than one loop at a time. More broadly, this takes LSR another
step closer to being able to reason about more than one loop at a time.

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.

fix a really nasty bug that Evan was tracking in SCCP. When resolving
...
undefs in branches/switches, we have two cases: a branch on a literal
undef or a branch on a symbolic value which is undef. If we have a
literal undef, the code was correct: forcing it to a constant is the
right thing to do.
If we have a branch on a symbolic value that is undef, we should force
the symbolic value to a constant, which then makes the successor block
live. Forcing the condition of the branch to being a constant isn't
safe if later paths become live and the value becomes overdefined. This
is the case that 'forcedconstant' is designed to handle, so just use it.
This fixes rdar://7765019 but there is no good testcase for this, the
one I have is too insane to be useful in the future.

hopefully sate the clang self host build, which is apparently
...
instantiating some folding set stuff that GCC isn't, requiring
some types to not be incomplete.
I don't know if clang is right or wrong, but unbreaking the
bot is goodness. Here's the broken build:

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.

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.
