Bug ID: 28979
Summary: [fast-math] support for math flags 'nsz', 'arcp',
'fast' in opt and TargetOptions
Product: libraries
Version: 3.8
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: l...@henning-thielemann.de
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
It seems that
opt -enable-no-infs-fp-math adds ninf globally
opt -enable-no-nans-fp-math adds nnan globally
but I do not see counterparts for the flags 'nsz', 'arcp' and 'fast'.
I also do not see corresponding flags in TargetOptions.
Am I missing something?
Is there another way to apply fast-math flags to whole functions or modules?
Or is it discouraged for some reason, anyway?
