Is cross-section inlining valid behaviour?

[Bingfeng Mei]

Hello, 

I came across a problem related to cross-section inlining. For the
following example, 

static void foo(void) __attribute__((section ("foo")));
 
static void foo(void)
{
  printf("Hello\n");
}
 
void bar(void) __attribute__((section ("bar")));
 
void bar(void)
{
  foo();
}

 
I compiled with the latest mainline gcc. 
gcc tst.c -O3 -S


The foo function is inlined into bar anyway even they have different
section attribute.  Is this a bug or expected behaviour? 
        .file   "tst.c"
        .section        .rodata.str1.1,"aMS",@progbits,1
.LC0:
        .string "Hello"
        .section        bar,"ax",@progbits
        .p2align 4,,15
.globl bar
        .type   bar, @function
bar:
.LFB3:
        movl    $.LC0, %edi
        jmp     puts
.LFE3:


Thanks.
