Jakob Stoklund Olesen	ed18a3e6b2	Remove -join-physregs from the test suite. ... This option has been disabled for a while, and it is going away so I can clean up the coalescer code. The tests that required physreg joining to be enabled were almost all of the form "tiny function with interference between arguments and return value". Such functions are usually inlined in the real world. The problem exposed by phys_subreg_coalesce-3.ll is real, but fairly rare. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157027 91177308-0d34-0410-b5e6-96231b3b80d8	2012-05-17 23:44:19 +00:00

Rafael Espindola	6d8628061b	Fix another case where we were preferring instructions with large ... immediates instead of 8 bits ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116410 91177308-0d34-0410-b5e6-96231b3b80d8	2010-10-13 17:14:25 +00:00
Rafael Espindola	dba81cf40e	Fix PR8365 by adding a more specialized Pat that checks if an 'and' with ... 8 bit constants can be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116403 91177308-0d34-0410-b5e6-96231b3b80d8	2010-10-13 13:31:20 +00:00
