Akira Hatanaka	168d4e5b20	[mips] Implement the following optimizations using dominance information to make PIC calls a little more efficient: 1. Remove instructions setting up $gp if it is known that a function has been called at least once. 2. Save the address of a called function in a register instead of loading it from the GOT at every call site. llvm-svn: 195892	2013-11-27 23:38:42 +00:00

1. Remove instructions setting up $gp if it is known that a function has been
   called at least once.
2. Save the address of a called function in a register instead of loading
