It seems Clang fans peruse GCC's bugzilla to showcase Clang vs GCC in their
talks. This exact example was used in a talk by Samsumg at LinuxCon Europe:

The compiler doesn't do that anymore, since at least 4.8. For example, in 4.8,
we emit this:
.text
.globl _g
_g:
pushl %ebp
movl %esp, %ebp
subl $8, %esp
movl $1, %eax
call L_f$stub
leave
ret
.section
__IMPORT,__jump_table,symbol_stubs,self_modifying_code+pure_instructions,5
L_f$stub:
.indirect_symbol _f
hlt ; hlt ; hlt ; hlt ; hlt
.subsections_via_symbols
and in trunk:
.text
.globl _g
_g:
LFB0:
pushl %ebp
LCFI0:
movl %esp, %ebp
LCFI1:
subl $8, %esp
call ___x86.get_pc_thunk.ax
L1$pb:
movl $1, %eax
call _f
leave
LCFI2:
ret
LFE0:
.section __TEXT,__textcoal_nt,coalesced,pure_instructions
