Bug ID: 104044
Summary: Useless empty statements (across projects)
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: roland.illig at gmx dot de
Target Milestone: ---
mn10300.c says:
> break;;
nvptx.c says:
> tree r = NULL_TREE;;
jit-playback.c says:
> tree x = as_tree ();;
These extra semicolons (and all the others in the whole tree) should be
removed, as they don't add any value. Quite the opposite, they create an
impression that the code were carelessly written.
I'm only concerned about obviously useless semicolons. In particular, I have
no problem with the empty statement in "while (i-- > 0) ;".
Is there a GCC warning for useless empty statements like these? I saw that
this was already reported as Bug 49053, but maybe your attitude towards this
topic changed in the past 5 years.
I stumbled upon these empty statements as I made the same mistake in my own
code.
