            Bug ID: 105648
           Summary: .cfi_startproc in wrong position when
                    -fpatchable-function-entry= is enabled on ppc64le
           Product: gcc
           Version: 11.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: giuliano.belinassi at gmail dot com
  Target Milestone: ---

With the following input file:
```
int func(int x)
{
  return x;
}
```
Saved as test.c, compiling with

> powerpc64le-suse-linux-gcc-11 -S -fpatchable-function-entry=1 test.c

results in an asm file with the following code:
```
func:
        .section        __patchable_function_entries,"awo",@progbits,func
        .align 3
        .8byte  .LPFE1
        .section        ".text"
.LPFE1:
        nop
.LFB0:
        .cfi_startproc
<... more code ...>
```
The position of .cfi_startproc is incorrect. It should be positioned right
after the function label.

As an example, on x86_64:

```
func:
.LFB0:
        .cfi_startproc
        .section        __patchable_function_entries,"awo",@progbits,func
        .align 8
        .quad   .LPFE1
        .text
.LPFE1:
        nop
<... more code ...>
```

Dup of PR99888?

Not sure if duplicate, but it certainly is related to PR99888 and PR98125.
