Does the LCP4357 support the FPU instruction set, e.g. VABS, VSQRT, etc (Sect. 7.2.3 Cortex-M4 Technical Reference Manual)?

There's no mention of these instructions in the user manual.

Yes, the LPC43xx implements the Cortex-M4 hardware floating point unit. This is specified in the Features list at the start of the LPC43xx user manual - but you are correct that the manual only lists the non-floating point instructions. I'll flag this to our docs team.

For more information on using floating point on LPC43xx see http://www.lpcware.com/content/faq/lpcxpresso/cm4-floating-point (which gives some general info as well as LPCXpresso specifics), and if using another toolchain, check their documentation.
