Hello!
clang defines some AttributeSet, for example:
attributes #0 = { nounwind uwtable
"less-precise-fpmad"="false"
"no-frame-pointer-elim"="true"
"no-frame-pointer-elim-non-leaf"="true"
"no-infs-fp-math"="false"
"no-nans-fp-math"="false"
"unsafe-fp-math"="false"
"use-soft-float"="false" }
I would like to know if there is any way to reuse such pre-defined
attribute sets (for example, set the attribute list of my new function
using an existing attribute set).
Thanks in advance,
--Raul

So if you have two functions which both have the same attributes, then they will reference the same AttributeSet object. -bw
