From c579b28f6281c9cc0b711a012c30bf00036c60bf Mon Sep 17 00:00:00 2001 From: Michal Nazarewicz Date: Wed, 3 Aug 2016 03:08:48 +0200 Subject: Replace decimalnump with alphanumericp MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit decimalnump was used in regex.c only in ISALNUM macro which ored it with alphabeticp. Because both of those functions require Unicode general category lookup, this resulted in unnecessary lookups (if alphabeticp return false decimalp had to perform another lookup). Drop decimalnump in favour of alphanumericp which combines decimelnump with alphabeticp. * src/character.c (decimalnump): Remove in favour of… (alphanumericp): …new function. * src/regex.c (ISALNUM): Use alphanumericp. --- src/character.c | 17 +++++++++++++---- src/character.h | 2 +- src/regex.c | 2 +- 3 files changed, 15 insertions(+), 6 deletions(-) diff --git a/src/character.c b/src/character.c index 9f60aa718d..b19e41d660 100644 --- a/src/character.c +++ b/src/character.c @@ -983,17 +983,26 @@ alphabeticp (int c) || gen_cat == UNICODE_CATEGORY_Nl); } -/* Return true if C is a decimal-number character. */ +/* Return true if C is a alphabetic or decimal-number character. */ bool -decimalnump (int c) +alphanumericp (int c) { Lisp_Object category = CHAR_TABLE_REF (Vunicode_category_table, c); if (!
