Both icc and gcc generate:

[...@gnu-26 pr42324]$ cat b4.c
extern unsigned int bartmp;

void foo(_Bool bar)
{
 bartmp = bar;
}
[...@gnu-26 pr42324]$ objdump -dw b4.o

b4.o:     file format elf64-x86-64


Disassembly of section .text:

0000000000000000 <foo>:
   0:   40 0f b6 ff             movzbl %dil,%edi
   4:   89 3d 00 00 00 00       mov    %edi,0x0(%rip)        # a <foo+0xa>
   a:   c3                      retq   
[...@gnu-26 pr42324]$
