Kevin P. Neal	5987749e33	Add constrained fptrunc and fpext intrinsics. ... The new fptrunc and fpext intrinsics are constrained versions of the regular fptrunc and fpext instructions.

Andrew Kaylor	a0a1164ce4	Add intrinsics for constrained floating point operations ... This commit introduces a set of experimental intrinsics intended to prevent optimizations that make assumptions about the rounding mode and floating point exception behavior. These intrinsics will later be extended to specify flush-to-zero behavior. More work is also required to model instruction dependencies in machine code and to generate these instructions from clang (when required by pragmas and/or command line options that are not currently supported).
