Hi, I try to build crosstool-0.27 with demo-arm.sh and it failed. while the demo-arm-softfloat.sh is ok. then i have a dumb question. what is the difference between these two? i mean what is the softfloat? i assumed that it is some float library implemented in software instead of computing it in hardware. :P
most arm hardware doesn't have floating point in hardware, but rather emulates the fp instructions in software. This emulation is slow. softfloat gets around this, and directly calls the fp software routines, so it's supposed to be faster. This is nonstandard but increasingly popular. Or so I hear. - Dan
