The first two of the three instructions that are emitted to initialize the global pointer register now use register $2.- Stop emitting .cpload directive.llvm-svn: 156689 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/Mips/global-pointer-reg.ll Sat, 12 May 2012 00:48:43 +0000 Akira Hatanaka <ahatanaka@mips.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/CodeGen/Mips/global-pointer-reg.ll#b049aef2 Add an option to use a virtual register as the global base register instead ofreserving a physical register ($gp or $28) for that purpose.This will completely eliminate loads that restore the value of $gp after everyfunction call, if the register allocator assigns a callee-saved register, oreliminate 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 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/Mips/global-pointer-reg.ll Fri, 24 Feb 2012 22:34:47 +0000 Akira Hatanaka <ahatanaka@mips.com>
