Utilities for dealing with flags related to floating point properties and mode controls.
Convenience struct for specifying and reasoning about fast-math flags.
StringRef - Represent a constant reference to a string, i.e.
This namespace contains an enum with a value for every intrinsic/builtin function known by LLVM.
ExceptionBehavior
Exception behavior used for floating point operations.
Definition FPEnv.h:39
@ ebStrict
This corresponds to "fpexcept.strict".
Definition FPEnv.h:42
@ ebMayTrap
This corresponds to "fpexcept.maytrap".
Definition FPEnv.h:41
@ ebIgnore
This corresponds to "fpexcept.ignore".
