From 2e55c34282273f69099bf90bc6d2f38959545e10 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Wed, 18 May 2022 09:36:00 +0200 Subject: [PATCH] gas: simplify ignore_input() First of all convert to switch(), in preparation of adding another directive here which may not be ignored. While doing so drop dead code: A string the first two characters of which do not match "if" also wont match "ifdef" or "ifndef". --- gas/cond.c | 24 +++++++++++++----------- 1 file changed, 13 insertions(+), 11 deletions(-) diff --git a/gas/cond.c b/gas/cond.c index b6e538a846f..ee441e1230e 100644 --- a/gas/cond.c +++ b/gas/cond.c @@ -513,17 +513,19 @@ ignore_input (void) } /* We cannot ignore certain pseudo ops. */ - if (((s[0] == 'i' - || s[0] == 'I') - && (!strncasecmp (s, "if", 2) - || !strncasecmp (s, "ifdef", 5) - || !strncasecmp (s, "ifndef", 6))) - || ((s[0] == 'e' - || s[0] == 'E') - && (!strncasecmp (s, "else", 4) - || !strncasecmp (s, "endif", 5) - || !strncasecmp (s, "endc", 4)))) - return 0; + switch (s[0]) + { + case 'i': case 'I': + if (s[1] == 'f' || s[1] == 'F') + return 0; + break; + case 'e': case 'E': + if (!strncasecmp (s, "else", 4) + || !strncasecmp (s, "endif", 5) + || !strncasecmp (s, "endc", 4)) + return 0; + break; + } return (current_cframe != NULL) && (current_cframe->ignoring); } -- 2.30.2
