From f02806be1ff3d25fdf4d9e06ced33c4b138458aa Mon Sep 17 00:00:00 2001 From: claziss Date: Mon, 23 Jul 2018 11:09:43 +0200 Subject: [PATCH] [ARC] Fix case-sensitivity for extension instructions. In ARC assembler, we accept case insensitive mnemonics, but this was not the case for extension instruction, fix it and add a test. gas/ Claudiu Zissulescu * config/tc-arc.c (tokenize_extinsn): Convert to lower case the name of extension instructions. * testsuite/gas/arc/textinsn_case.d: New file. * testsuite/gas/arc/textinsn_case.s: Likewise. --- gas/ChangeLog | 7 +++++++ gas/config/tc-arc.c | 4 ++++ gas/testsuite/gas/arc/textinsn_case.d | 9 +++++++++ gas/testsuite/gas/arc/textinsn_case.s | 6 ++++++ 4 files changed, 26 insertions(+) create mode 100644 gas/testsuite/gas/arc/textinsn_case.d create mode 100644 gas/testsuite/gas/arc/textinsn_case.s diff --git a/gas/ChangeLog b/gas/ChangeLog index 5df35569..dbaa02d 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,10 @@ +2018-07-23 Claudiu Zissulescu + + * config/tc-arc.c (tokenize_extinsn): Convert to lower case the + name of extension instructions. + * testsuite/gas/arc/textinsn_case.d: New file. + * testsuite/gas/arc/textinsn_case.s: Likewise. + 2018-07-22 H.J.
