Dynamic stack realignment use of sp register as source/dest register2009-12-06T22:39:50ZAnton Korobeynikovasl@math.spbu.ru2009-12-06T22:39:50Zurn:sha1:7cca606aaa6fee6ff4f548aa3686608b6be1f208
in "bic sp, sp, #15" leads to unpredicatble behaviour in Thumb2 mode.
Emit the following code instead:
mov r4, sp
bic r4, r4, #15
mov sp, r4

It turns out most of the thumb2 instructions are not allowed to touch SP. The semantics of such instructions are unpredictable. We have just been lucky that tests have been passing.2009-08-07T00:34:42ZEvan Chengevan.cheng@apple.com2009-08-07T00:34:42Zurn:sha1:861986401e05e437cb33bfd8320d510b956fe41e
This patch takes pain to ensure all the PEI lowering code does the right thing when lowering frame indices, insert code to manipulate stack pointers, etc. It's also custom lowering dynamic stack alloc into pseudo instructions so we can insert the right instructions at scheduling time.
This fixes PR4659 and PR4682.

- More refactoring. This gets rid of all of the getOpcode calls.2009-07-28T05:48:47ZEvan Chengevan.cheng@apple.com2009-07-28T05:48:47Zurn:sha1:6495f63945e8dbde81f03a1dc2ab421993b9a495
- This change also makes it possible to switch between ARM / Thumb on a
per-function basis.
- Fixed thumb2 routine which expand reg + arbitrary immediate. It was using
using ARM so_imm logic.
- Use movw and movt to do reg + imm when profitable.
- Other code clean ups and minor optimizations.
