Simon Atanasyan d52b14937d [mips] Reduce number of instructions used for loading a global symbol's value ... Now `lw/sw $reg, sym+offset` pseudo instructions for global symbol `sym` are lowering into the following three instructions. ``` lw $reg, %got(symbol)($gp) addiu $reg, $reg, offset lw/sw $reg, 0($reg) ``` It's possible to reduce the number of instructions by taking the offset in account in the final `lw/sw` command. This patch implements that optimization. ``` lw $reg, %got(symbol)($gp) lw/sw $reg, offset($reg) ``` Differential Revision: https://reviews.llvm.org/D66553 llvm-svn: 369756		2019-08-23 13:36:24 +00:00
