This also occurs on AMD64 without any special attributes (the ABI passes params
in registers already).
When compiling:
extern char c2(char);
char c1(char c) { return c2(c); }
with gcc -Wall -O2 -S tail-char.c
using gcc (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8)
The result is:
c1:
subq $8, %rsp
movsbl %dil,%edi
call c2
addq $8, %rsp
movsbl %al,%eax
ret
