Kirill, this is a regression:
[hjl@gnu-6 gcc]$ cat /tmp/x.i
int (*ptr) (int);
int
foo (int f)
{
return (*ptr)(f);
}
[hjl@gnu-6 gcc]$ ./xgcc -B./ -O2 -foptimize-sibling-calls -fno-ipa-cp -S
/tmp/x.i -fPIC
[hjl@gnu-6 gcc]$ cat x.s
.file "x.i"
.text
.p2align 4,,15
.globl foo
.type foo, @function
foo:
.LFB0:
.cfi_startproc
subq $8, %rsp
.cfi_def_cfa_offset 16
movq ptr@GOTPCREL(%rip), %rax
call *(%rax)
addq $8, %rsp
.cfi_def_cfa_offset 8
ret
PTR here isn't an argument.
