From 66a6900a09dc32b8afc5bf61ee070084025232a7 Mon Sep 17 00:00:00 2001 From: Jie Zhang Date: Fri, 4 Sep 2009 04:29:42 +0000 Subject: [PATCH] gas/ * config/bfin-parse.y (asm_1): Implement HLT instruction. Fix comments for DBGA, DBGAH and DBGAL. * config/tc-bfin.c (bfin_gen_pseudodbg_assert): Change according to the new encoding of DBGA, DBGAH, and DBGAL. include/ * opcode/bfin.h (PseudoDbg_Assert): Add bits_grp and mask_grp. (PseudoDbg_Assert_grp_bits, PseudoDbg_Assert_grp_mask): Define. (PseudoDbg_Assert_dbgop_bits, PseudoDbg_Assert_dbgop_mask, PseudoDbg_Assert_dontcare_bits, PseudoDbg_Assert_dontcare_mask): Adjust accordingly. (init_PseudoDbg_Assert): Add PseudoDbg_Assert_grp_bits and PseudoDbg_Assert_grp_mask. opcodes/ * bfin-dis.c (decode_pseudodbg_assert_0): Change according to the new encoding of DBGA, DBGAH, and DBGAL.
