From 692166c24476b9123ca7dbb999e458a1f7fa2faa Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Mon, 28 Mar 2016 22:51:12 +0100 Subject: [PATCH] gas/arc: Allow greater range of characters into flag names An upcoming commit will add a new arc instruction flag that uses characters that have never appeared in an arc instruction flag before. Currently the assembler is very conservative about which characters can or cannot appear in an instruction flag. This commit relaxes these constraints a little. After this commit all alpha-numeric characters are now allowed into instruction flags. This complete set is not required for the upcoming change, however, having this slightly larger set does not impact the assemblers ability to correctly parse input, but does make it easier to add new flag to the instruction table. gas/ChangeLog: * config/tc-arc.c (tokenize_flags): Allow greater range of characters into flag names. --- gas/ChangeLog | 5 +++++ gas/config/tc-arc.c | 3 ++- 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/gas/ChangeLog b/gas/ChangeLog index 830afa5c781..0126fb81f77 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,8 @@ +2016-04-07 Andrew Burgess + + * config/tc-arc.c (tokenize_flags): Allow greater range of + characters into flag names. + 2016-04-07 Andrew Burgess * config/tc-arc.c (find_opcode_match): Handle O_symbol case, add diff --git a/gas/config/tc-arc.c b/gas/config/tc-arc.c index 04ccd07d120..154e838974b 100644 --- a/gas/config/tc-arc.c +++ b/gas/config/tc-arc.c @@ -1080,7 +1080,8 @@ tokenize_flags (const char *str, if (num_flags >= nflg) goto err; - flgnamelen = strspn (input_line_pointer, "abcdefghilmnopqrstvwxz"); + flgnamelen = strspn (input_line_pointer, + "abcdefghijklmnopqrstuvwxyz0123456789"); if (flgnamelen > MAX_FLAG_NAME_LENGTH) goto err;
