demo:

LLVM ERROR: Error parsing inline asm
Only problem seems to be that the parser finalizes OutStreamer
at the end of the first inline asm, which isn't what we want.
For example:
$ cat asm.c
int foo(int X) {
__asm__ ("incl %0" : "+r" (X));
return X;
}
$ clang asm.c -S -o - -emit-llvm | llc
...
subq $8, %rsp
movl %edi, (%rsp)
movl %edi, %eax
## InlineAsm Start
incl %eax
## InlineAsm End
movl %eax, (%rsp)
movl %eax, 4(%rsp)
addq $8, %rsp
ret
$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000 subq $0x08,%rsp

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.

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.
