[PATCH] Caller/Calllee unsafe-fp-math attribute fixup prior to inlining.

[Puyan Lotfi]

Hi All

The following patch checks that when inlining a callee into a a caller with unsafe-fp-math set, that the callee also has the attribute for unsafe-fp-math set (or others that apply) too. 
The idea is to make the caller being altered by inlining be as safe as the callee, and the check is made immediately prior to the actual inlining (where it will modify whatever function attributes necessary).

Could someone review this please?

Thanks

P.S.

This is a ping of a patch I sent previously, but I thought I’d rewrite the email body for clarity.
