Louis Gerbarg	3a6b5e0f17	Fix ARM bswap16.ll test on Windows ... Windows on ARM only supports thumb mode execution, so we have to explicitly pick some non-Windows OS to test ARM mode codegen. llvm-svn: 208638	2014-05-12 22:13:07 +00:00
Louis Gerbarg	acd97f5881	Add support bswap16 to/from memory compiling to rev16 on ARM/Thumb ... The current patterns for REV16 misses mostn __builtin_bswap16() due to legalization promoting the operands to from load/stores toi32s and then truncing/extending them. This patch adds new patterns that catch the resultant DAGs and codegens them to rev16 instructions. Tests included. rdar://15353652 llvm-svn: 208620	2014-05-12 19:53:52 +00:00
