Subject: [arm] Add default FPU for Marvell-pj4
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cdb77369ca02673e878b1a1b7856de0f979d2fec;p=gcc.git

[arm] Add default FPU for Marvell-pj4

According to GAS, the Marvell PJ4 CPU has a VFPv3-D16 floating point
unit, but GCC's CPU configuration tables omits this meaning that
-mfpu=auto will not correctly select the FPU.  This patch fixes this
by adding the +fp option to the architecture specification for this
device.

	* config/arm/arm-cpus.in (marvel-pj4): Add +fp to the architecture.
