Tim Northover	fa36dfeeca	Darwin-ARM: use movw/movt for static relocations ... llvm-svn: 195759	2013-11-26 12:45:05 +00:00
Jakob Stoklund Olesen	4fd0e4f415	Transfer memory operands to the right instruction. ... They need to go on the PICLDR as the verifier points out. llvm-svn: 157151	2012-05-20 06:38:42 +00:00
Evan Cheng	518bcd0ef4	Don't use movw / movt for iOS static codegen for now to workaround some tools issues. rdar://9514789 ... llvm-svn: 132211	2011-05-27 20:11:27 +00:00
Evan Cheng	97c9f84f68	Add iOS test ... llvm-svn: 132203	2011-05-27 19:04:21 +00:00
Anton Korobeynikov	2522908653	Materialize global addresses via movt/movw pair, this is always better ... than doing the same via constpool: 1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2. 2. Load from constpool might stall up to 300 cycles due to cache miss. 3. Movt/movw does not use load/store unit. 4. Less constpool entries => better compiler performance. This is only enabled on ELF systems, since darwin does not have needed relocations (yet). llvm-svn: 89720	2009-11-24 00:44:37 +00:00
