[PATCH] D62731: Add support for options -frounding-math, -ftrapping-math, -ffp-model=, and -ffp-exception-behavior=, : Specify floating point behavior

[Melanie Blower via Phabricator via cfe-commits]

mibintc updated this revision to Diff 230128.
mibintc added a comment.

Here's an update in response to comments from @michele.scandale 
I fixed the assertion error and added a test case
I fixed the setting of ftrapping-math in CodeGenOpts
I deleted an incorrect comment
I added a diagnostic when -fp-exception-behavior= is overridden on the command line by f[no-]trapping-math
I updated one of the test cases to work with some small modifications that will be made to IRBuilder.h
