Incorrect return values for APFloat::convertFromString?
I noticed some odd behavior with APFloat's convertFromString method.
1. If I pass the hex representation of the closest value to 0.1 (0x19999Ap-24), everything is fine and opOk is returned. However, if I pass the same value as a decimal string (0.10000002384185791015625), opInexact is set.
2. On the lower end of the scale, the smallest denormal 0x1p-149 returns opOk, but the slightly larger value 0x1.8p-149 has opUnderflow set and (as expected) opInexact.
Is this behavior correct?

[LLVMdev] Soft floating point support
This patch supplies software IEEE floating point support.
The comment from the patch reproduced below says all there is
to say.
This patch contains the prior "cleanup" patch; please don't apply
that one.
Please let me know of any bugs. It is tested reasonably well,
but until I put together random tests it's hard to have 100%
confidence.
Neil.
