From 6e7ced37e756420742d51abb044c24d0f1929143 Mon Sep 17 00:00:00 2001 From: "Jose E. Marchesi" Date: Wed, 13 Jul 2016 01:42:28 -0700 Subject: opcodes,gas: support for the ldtxa SPARC instructions. This patch adds support for the LDTXA instructions, along with the corresponding ASIs. Tests for GAS are included. opcodes/ChangeLog: 2016-07-12 Jose E. Marchesi * sparc-opc.c (ldtxa): New macro. (sparc_opcodes): Use the macro defined above to add entries for the LDTXA instructions. (asi_table): Add the ASI_TWINX_* asis used in the LDTXA instruction. gas/ChangeLog: 2016-07-12 Jose E. Marchesi * testsuite/gas/sparc/ldtxa.s: New file. * testsuite/gas/sparc/ldtxa.d: Likewise. * testsuite/gas/sparc/sparc.exp: Execute the ldtxa test. --- opcodes/ChangeLog | 8 ++++++++ opcodes/sparc-opc.c | 34 ++++++++++++++++++++++++++++++++++ 2 files changed, 42 insertions(+) (limited to 'opcodes') diff --git a/opcodes/ChangeLog b/opcodes/ChangeLog index 56f33b5..091d8d4 100644 --- a/opcodes/ChangeLog +++ b/opcodes/ChangeLog @@ -1,3 +1,11 @@ +2016-07-12 Jose E.
