This API was added for #25819, where it was discussed as math.FMA. The commit adding it used math.Fma, presumably for consistency with the rest of the unusual names in package math (Sincos, Acosh, Erfcinv, Float32bits, etc). I believe that using an idiomatic Go name is more important here than consistency with these other names, most of which are historical baggage from C's standard library. Early additions like Float32frombits happened before "uppercase for export" (so they were originally like "float32frombits") and they were not properly reconsidered when we uppercased the symbols to export them. That's a mistake we live with. The names of functions we have added since then, and even a few that were legacy, are more properly Go-cased, such as IsNaN, IsInf, and RoundToEven, rather than Isnan, Isinf, and Roundtoeven. And also constants like MaxFloat32. For new API, we should keep using proper Go-cased symbols instead of minimally-upper-cased-C symbols. So math.FMA, not math.Fma. This API has not yet been released, so this change does not break the compatibility promise. This CL also modifies cmd/compile, since the compiler knows the name of the function. I could have stopped at changing the string constants, but it seemed to make more sense to use a consistent casing everywhere.

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.
To run just these tests, execute:
../bin/go run run.go
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:
- it is most naturally expressed using the test runner; or
- it is also applicable to
gccgoand other Go tool chains.
