* | cherry-pick gcc r217091.Yiran Wang2015-07-082-0/+19
|/ | | | | | | | | | | | | | | This change is re-based and modified to work with the older context, as the context code is changed a lot in GCC trunk. It is about to insert some barriers on stack-pointer register, so that the adjust-stack-pointer code does not get scheduled before any code in the fuction epilogue, which may access some stack space without explicit use of stack pointer. Examples are a load from an auto array and some access to an area of alloca. Anyway, the barriers would make all such alias dependences not violated. For more details, please refer to GCC bug 63293. (Personally I think there may be a bit too many barriers generated.) Change-Id: I61ea54e500b6965feab69a62165d10b6c3a21c20

* Update register class information when register assigned by IRA.Yiran Wang2015-06-154-1/+98
| | | | | | | | | | | | The update is necessary so that LRA is able to detect the conflict between these regisers and LRA registers. The change is a back-port from GCC 5.0 r217783, and please refer to gcc bug 63762 for some details. That bug report has an example, which is about VFP register file, but the issue applies to ARM integer register file too, with the same mechanism. The change is mainly about Thumb, although theoretically not limitted to. Change-Id: I1fedb410ae5ca39f168dab874f310d7337ab9bcc
