Richard Sandiford	e3cc30d00b	[SystemZ] Add FI[EDX]BRA ... These are extensions of the existing FI[EDX]BR instructions, but use a spare bit to suppress inexact conditions. llvm-svn: 188894	2013-08-21 08:58:08 +00:00
Richard Sandiford	5869a6bb53	[SystemZ] Add RISBLG and RISBHG instruction definitions ... The next patch will make use of RISBLG for codegen. llvm-svn: 187490	2013-07-31 11:17:35 +00:00
Richard Sandiford	8de9a94d5e	[SystemZ] Add STOC and STOCG ... These instructions are allowed to trap even if the condition is false, so for now they are only used for "*ptr = (cond ? x : *ptr)"-style constructs. llvm-svn: 187111	2013-07-25 08:57:02 +00:00
Richard Sandiford	36b6ee625e	[SystemZ] Start adding z196 and zEC12 support ... This first step just adds definitions for SLLK, SRLK and SRAK. The next patch will actually make use of them during codegen. insn-bad.s tests that some form of error is reported when using these instructions on z10. More work is needed to get the "instruction requires: distinct-ops" that we'd ideally like, so I've stubbed that part out for now. I'll come back and make it mandatory once the necessary changes are in. llvm-svn: 186680	2013-07-19 16:09:03 +00:00
