From 2a14b21acd056499cb150014e93d805a5ade2ce1 Mon Sep 17 00:00:00 2001 From: Aleksandar Markovic Date: Thu, 2 Nov 2017 12:14:05 +0100 Subject: MIPS: math-emu: Mark fall throughs in switch statements with a comment Mark intentional fall throughs in switch statements with a consistent comment. In most of the cases, a new comment line containing text "fall through" is inserted. In some of the cases, existing comment contained a variation of the text "fall through" (for example, "FALL THROUGH" or "drop through"). In such cases, the existing comment is modified to contain "fall through". Lastly, in two cases, code segments were described in comments as "fall througs", but were in reality "breaks out" of switch statement. In such cases, existing comments are accordingly modified. Apart from making code easier to follow and debug, this change enables some static code analysers to interpret newly inserted comments as their annotations (and, therefore, not issue warnings of type "fall through in switch statement", which is desireable, since marked fallthroughs are intentional).
