Subject: [RFC] treewide: cleanup unreachable breaks
Date: Sat, 17 Oct 2020 09:09:28 -0700
Message-ID: <20201017160928.12698-1-trix@redhat.com> (raw)

From: Tom Rix <trix@redhat.com>

This is a upcoming change to clean up a new warning treewide.
I am wondering if the change could be one mega patch (see below) or
normal patch per file about 100 patches or somewhere half way by collecting
early acks.

clang has a number of useful, new warnings see
https://clang.llvm.org/docs/DiagnosticsReference.html

This change cleans up -Wunreachable-code-break
https://clang.llvm.org/docs/DiagnosticsReference.html#wunreachable-code-break
for 266 of 485 warnings in this week's linux-next, allyesconfig on x86_64.

The method of fixing was to look for warnings where the preceding statement
was a simple statement and by inspection made the subsequent break unneeded.
In order of frequency these look like

return and break

 	switch (c->x86_vendor) {
 	case X86_VENDOR_INTEL:
 		intel_p5_mcheck_init(c);
 		return 1;
-		break;

goto and break

 	default:
 		operation = 0; /* make gcc happy */
 		goto fail_response;
-		break;

break and break
 		case COLOR_SPACE_SRGB:
 			/* by pass */
 			REG_SET(OUTPUT_CSC_CONTROL, 0,
 				OUTPUT_CSC_GRPH_MODE, 0);
 			break;
-			break;

The exception to the simple statement, is a switch case with a block
and the end of block is a return

 			struct obj_buffer *buff = r->ptr;
 			return scnprintf(str, PRIV_STR_SIZE,
 					"size=%u\naddr=0x%X\n", buff->size,
 					buff->addr);
 		}
-		break;

Not considered obvious and excluded, breaks after
multi level switches
complicated if-else if-else blocks
panic() or similar calls

And there is an odd addition of a 'fallthrough' in drivers/tty/nozomi.c

Tom
