The only idea on size difference I have is:
headers text in many of FP-emulation files from compiler_rt contains lines like:
// This file implements quad-precision soft-float addition ***with the
IEEE-754 default rounding*** (to nearest, ties to even).

Had anyone a chance to compare FP implementation in compiler_rt? I
still wonder why the sizes differ so much, Incomplete implementation
in compiler_rt?
compiler_rt claims it is IEEE-compliant.

Compile: $(INSTALL)/bin/i586-intel-elfiamcu-gcc -Os addsf3.c -c
Check function size: nm -S -t dec addsf3.o
I get:
0522 T __addsf3
So the size is ~0.5K.
Why so large difference in libgcc and compiler_rt for the same functionality?
Thanks.
