*	Delete all functions that are no longer needed in MipsFunctionInfo, including	Akira Hatanaka	2012-05-12	1	-7/+0
\| \| \| \| \| \| \| \| \|	the ones that get or set the frame index for the $gp save slot. Remove the piece of code in MipsFunctionInfo::getGlobalBaseReg() which returns GP. This function should always return a virtual register. llvm-svn: 156695
*	Do not use $gp as a dedicated global register if the target ABI is not O32.	Akira Hatanaka	2012-04-25	1	-2/+2

This will completely eliminate loads that restore the value of $gp after every function call, if the register allocator assigns a callee-saved register, or eliminate unnecessary loads if it assigns a temporary register. example: .cpload $25 // set $gp. ... .cprestore 16 // store $gp to stack slot 16($sp). ... jalr $25 // function call. clobbers $gp. lw $gp, 16($sp) // not emitted if callee-saved reg is chosen. ... lw $2, 4($gp) ... jalr $25 // function call. lw $gp, 16($sp) // not emitted if $gp is not live after this instruction. ... llvm-svn: 151402
*	remove Emacs-tag form .cpp files in Mips Backend, and fix some typo.	Jia Liu	2012-02-17	1	-1/+1
