GLSL: fma() command for Radeon graphics cards

Good day to all!

I have created a computational shader that works well when compiling for NVIDIA graphics cards (3070, 4080 and A100), but shows an error when compiling for AMD graphics cards (RX 580, at least); error text:

Spoiler
QOpenGLShader::compile(Compute): 0:446(21): error: syntax error, unexpected NEW_IDENTIFIER, expecting ')' or ',' ".

The fma() command is located at the specified "coordinates".

Do I understand correctly that fma() is not implemented in AMD drivers?
