sqrtf() throws a domain error, even though I guard against negative numbers

QUESTION

sqrtf() throws a domain error, even though I guard against negative numbers

Asked 2020-Aug-14 at 02:32

I am normalizing a 3D vector, and the clang-9 generated code throws a SIGFPE on the sqrtf() even though I do a test before calling it.

Note that I run with FP exceptions enabled.

throws a domain error, even thoug I guard against negative numbers

But if (lensq > FLT_EPSILON) is too late as earlier dx*dx + dy*dy + dz*dz caused int overflow. "and indeed overflow, causing lensq to be negative" - which is undefined behavior UB.

Compiler can take advantage that sqrtf(lensq) can always work because it can assume dx*dx + dy*dy + dz*dz >= 0 and so lensq >= 0.0f.

Get rid of UB.
