[PATCH] D88238: [APFloat] convert SNaN to QNaN in convert() and raise Invalid signal

[Sanjay Patel via Phabricator via llvm-commits]

spatel updated this revision to Diff 295375.
spatel added a comment.

Added tests that use `__builtin_nanf` and `__builtin_nansf` (no changes with this patch as a whole or split into 2 pieces). We allow creating 32-bit NAN directly with those builtins.

This may be confusing because LLVM IR doesn't print 32-bit FP as 32-bit hex. That's the FIXME note in AsmWriter.cpp and hopefully the next step...although I suspect it would mean updating several hundred regression tests.
