* [mips] Make Static a default relocation model for MIPS codegenPetar Jovanovic2016-04-111-9/+9
| | | | | | | | | | | | This change follows up defaults for GCC and Clang, so LLVM does not differ from them. While number of the test files are touched with this change, they all keep the old (expected) behaviour with the explicit option: "-relocation-model=pic" The tests that have not been touched are insensitive to relocation model.

* [mips] Add support for dynamic stack realignment.Vasileios Kalintiris2015-06-021-0/+299
Summary: With this change we are able to realign the stack dynamically, whenever it contains objects with alignment requirements that are larger than the alignment specified from the given ABI. We have to use the $fp register as the frame pointer when we perform dynamic stack realignment. In complex stack frames, with variably-sized objects, we reserve additionally the callee-saved register $s7 as the base pointer in order to reference locals.
