67 --------------------
68 Earlier versions of VFP (prior to version 3) rely on software support for things
69 like IEEE-754 compliant underflow handling etc. When the VFP unit needs such
70 software assistance, it signals the kernel by raising an undefined instruction
72 current instruction and arguments, and emulates the instruction in software.
74 Such software assistance is currently not implemented for VFP instructions
80 ---------------------------------------
84 instructions of its own at -O3 level if -mfpu=neon is selected, and even if the
85 kernel is currently compiled at -O2, future changes may result in NEON/VFP

95 built with the GCC flag '-mfpu=neon' set.
97 As the kernel is compiled with '-msoft-float', the above will guarantee that
