Multiplication by max fp64 is not elementwise

[joelberkeley]

On the CPU runtime, multiplying this array

[0.20099818632866118, 0.5067824359585911, 0.9694182218020597, -0.9592309562855535, 0.3099884705960516, -0.888345123577424, 0.3422581826548319, -0.07179653823829113, 0.010391347657845218, 0.7492772695497909]

by max fp64 1.7976931348623157e308 (from APFloat::getLargest) yields infinities. Meanwhile multiplying just the first element yields 3.6133305968281075e307.

I have not tried other runtimes.

Hi @joelberkeley ,

Thank you for creating this issue. To help us investigate, please share the steps you performed and simple standalone code snippet to reproduce the problem.

openxla is a backend to my library, indeed I don't even write in C++, so writing an example is not trivial. Did you try the above instructions and it didn't work, or do you want an example first?
