--- Comment #3 from Senthil Kumar Selvaraj <senthil_kumar.selvaraj at atmel dot

Happens on a recent trunk build as well.
Here's a simpler testcase.
$ cat foo.c
void foo (char a, unsigned int b);
void readx (const char __memx *x)
{
foo (*x, 0xABCD);
}
$ avr-gcc -mmcu=atmega1280 foo.c -S -Os
$ cat foo.s
<snip>
mov r18,r22
mov r25,r23
ldi r22,lo8(-51); Load 0xABCD into r22:r23 in prep for call to foo
ldi r23,lo8(-85)
mov r30,r18
mov r31,r25
mov r21,r24
call __xload_1; r22 clobbered here
mov r24,r22
jmp foo
