It's not strictly a bug but a "missed optimization".  Could you fill
in a bugzilla report on GCC for this?  If you replace the "uint8_t" by
"unsigned char", no further preprocessing is needed, so you can
attacht that example directly to the report.  Please do also attach
the *generated* assembly code (rather than the disassembly listing),
this is what you get by using the -S compiler option.
