Hi,

The patch contains some cleanups for the AVR target:

 * move 'call_insn_operand' predicate from 'avr.c' file to 'predicates.md'.

 * in *push<mode> insns use 'reg_or_0_operand' predicate instead the condition 
 and REG_SP constraint instead magic number 32.

No new regresion in GCC testsuite.

	* config/avr/avr-protos.h (call_insn_operand): Delete prototype.
	* config/avr/avr.c (call_insn_operand): Delete function.
	* config/avr/avr.md (*pushqi, *pushhi, *pushsi, *pushsf): Use REG_SP
	instead of register number. Use predicates.
	* config/avr/predicates.md (const0_operand, reg_or_0_operand, 
	call_insn_operand): Add.

Anatoly.
