FPU version for Cortex-M microcontrollers

From a simple google search, I found out that the fpu version for Tiva C Launchpad is fpv4-sp-d16 but which document tells the fpu version of various microcontrollers(tm4c123gh6pm, stm32f407, stm32f446re, etc.)?

arm-none-eabi-gcc --print-multi-lib

gives the information about architecture and abi but fpu version is not mentioned for a particular architectute.
