The tLDR et al instructions were emitting either a reg/reg or reg/imm
...
instruction based on the t_addrmode_s# mode and what it returned. There is some
obvious badness to this. In particular, it's hard to do MC-encoding when the
instruction may change out from underneath you after the t_addrmode_s# variable
is finally resolved.
The solution is to revert a long-ago change that merged the reg/reg and reg/imm
versions. There is the addition of several new addressing modes. They no longer
have extraneous operands associated with them. I.e., if it's reg/reg we don't
have to have a dummy zero immediate tacked on to the SDNode.
There are some obvious cleanups here, which will happen shortly.

Clean up the 'trap' instruction printing a bit. Non-Darwin assemblers don't
...
(yet) recognize the 'trap' mnemonic, so we use .short/.long to emit the
opcode directly. On Darwin, however, we do want the mnemonic for more
readable assembly code and better disassembly.
Adjust the .td file to use the 'trap' mnemonic and handle using the binutils
workaround in the assembly printer. Also tweak the formatting of the opcode
values to make them consistent between the MC printer and the old printer.

Change ARM VFP VLDM/VSTM instructions to use addressing mode #4 , just like
...
all the other LDM/STM instructions. This fixes asm printer crashes when
compiling with -O0. I've changed one of the NEON tests (vst3.ll) to run
with -O0 to check this in the future.
Prior to this change VLDM/VSTM used addressing mode #5 , but not really.
The offset field was used to hold a count of the number of registers being
loaded or stored, and the AM5 opcode field was expanded to specify the IA
or DB mode, instead of the standard ADD/SUB specifier. Much of the backend
was not aware of these special cases. The crashes occured when rewriting
a frameindex caused the AM5 offset field to be changed so that it did not
have a valid submode. I don't know exactly what changed to expose this now.
Maybe we've never done much with -O0 and NEON. Regardless, there's no longer
any reason to keep a count of the VLDM/VSTM registers, so we can use
addressing mode #4 and clean things up in a lot of places.

Eliminate the remaining uses of getTypeSize. This

should only effect x86 when using long double. Now
12/16 bytes are output for long double globals (the
exact amount depends on the alignment). This brings
globals in line with the rest of LLVM: the space
reserved for an object is now always the ABI size.
One tricky point is that only 10 bytes should be
output for long double if it is a field in a packed
struct, which is the reason for the additional
argument to EmitGlobalConstant.

- Fix codegen for pc relative constant (e.g. JT) in thumb mode:
...
.set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
LPCRELL0:
add r1, pc, #PCRELV0
This is not legal since add r1, pc, #c requires the constant be a multiple of 4.
Do the following instead:
.set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
LPCRELL0:
mov r1, #PCRELV0
add r1, pc
- In thumb mode, it's not possible to use .set generate a pc relative stub
address. The stub is ARM code which is in a different section from the thumb
code. Load the value from a constpool instead.
- Some asm printing clean up.

instructions into one (e.g. tLDRrr, tLDRri -> tLDR).

address is not an add, materialize a 0 immediate into a register and use
it as the offset field.
