Dan Gohman	c8054d90fb	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81293	2009-09-09 00:09:15 +00:00
Richard Osborne	bfdc557c8a	Expand unaligned 32 bit loads from an address which is a constant ... offset from a 32 bit aligned base as follows: ldw low, base[offset >> 2] ldw high, base[(offset >> 2) + 1] shr low_shifted, low, (offset & 0x3) * 8 shl high_shifted, high, 32 - (offset & 0x3) * 8 or result, low_shifted, high_shifted Expand 32 bit loads / stores with 16 bit alignment into two 16 bit loads / stores. llvm-svn: 75902	2009-07-16 10:42:35 +00:00
Richard Osborne	25b33cb035	Custom lower unaligned 32 bit stores and loads into libcalls. This is ... a big code size win since before they were expanding to upto 16 instructions. llvm-svn: 75901	2009-07-16 10:21:18 +00:00
