Re-commit: [mips] abs.[ds], and neg.[ds] should be allowed regardless of -enable-no-nans-fp-math Summary: They behave in accordance with the Has2008 and ABS2008 configuration bits of the processor which are used to select between the 1985 and 2008 versions of IEEE 754. In 1985 mode, these instructions are arithmetic (i.e. they raise invalid operation exceptions when given NaN), in 2008 mode they are non-arithmetic (i.e. they are copies). nmadd.[ds], and nmsub.[ds] are still subject to -enable-no-nans-fp-math because the ISA spec does not explicitly state that they obey Has2008 and ABS2008. Fixed the issue with the previous version of this patch (r205628). A pre-existing 'let Predicate =' statement was removing some predicates that were necessary for FP64 to behave correctly.

; Check that madd.[ds], msub.[ds], nmadd.[ds], and nmsub.[ds] are supported
; correctly.
; The spec for nmadd.[ds], and nmsub.[ds] does not state that they obey the
; the Has2008 and ABS2008 configuration bits which govern the conformance to
; IEEE 754 (1985) and IEEE 754 (2008). These instructions are therefore only
; available when -enable-no-nans-fp-math is given.
Add extra CHECK prefix to tests with explicit prefix These tests mistakenly assume that CHECK is still available even if an explicit prefix is specified. llvm-svn: 201492
