I just found out what's causing this confusion. If you compile your program
like this:
avr-gcc -Os -mmcu=atmega168 -lm main.c -o main.elf
__clz_tab gets included. But if you compile like this:
avr-gcc -Os

Note that the use of clz for the avr is avoided by using avr-libc's math
library.
Not confirmed. A simple test program using a floating point number:
This is probably due to

Something like this is smaller, faster and works for all registers (no need for
LD_regs). And could easily be writtin in to a insn:
; rOut: output register
; rIn: input register
; rIn, Z, N

Change target milestone to 4.2.3, as 4.2.2 has been released.

Here's what I see:
The array __clz_tab is used in a macro, count_leading_zeros, which is called
in
the function __clzSI2 in libgcc2.c, which (AFAICT) gets compiled to the
function __clzsi2 and

Here's an untested (I'm going to try to figure out how to get it to build into
the AVR build) function that replaces the definition of clz_tab with a 6
instruction bit of code:
; r2 in, r3 out

Will not be fixed in 4.2.0; retargeting at 4.2.1.

Anatoly, can you have a look? It's a regression in 4.2 for AVR!

Someone else is going to have to look into this as this works just fine on
spu-elf.
