* gas/opcodes: blackfin: punt BYTEOP2M insn supportMike Frysinger2011-02-131-1/+0
| | | | | | | The BYTEOP2M insn was part of the initial Blackfin designs, but never made it into any actual silicon. So punt support for it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* gas: blackfin: reign in overeager insn flag handlingMike Frysinger2010-10-111-7/+8
| | | | | | | | | | | | | | | | | | | Currently, trying to declare single letter variables in Blackfin assembly can sometimes lead to parser errors if that letter is used for insn flags. For example, X, Z, S, M, and T are used to change the behavior of insns: R0 = 1; R0 = 1 (X); R0 = 1 (Z); But the current parser just looks for single letter tokens rather than ones that show up in the (FLAGS) field. So only match these letters as flags when they're in parentheses. Not a complete fix, but it at least lets gcc tests pass now (the test gcc/testsuite/gcc.c-torture/compile/mangle-1.c to be exact). A complete fix would require a significant parser rewrite in order to handle: R0 = (x) (x); /* zero extend the address of the symbol "x" */ R0 = W; R0 = W[P0]; Signed-off-by: Steve Kilbane <steve.kilbane@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* gas: blackfin: handle multibyte symbolsMike Frysinger2010-09-221-1/+1
| | | | | | | | | | Accept any 8bit char with the high bit set so as to support multibyte characters. Also use the locale safe regular expressions to match chars/digits. This brings the Blackfin assembler inline with the behavior of other assemblers. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* opcodes/gas: blackfin: handle more ASTAT flagsMike Frysinger2010-09-221-0/+3
| | | | | | | | Support a few more ASTAT bits with the standard insns that operate on ASTAT bits directly. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* gas: blackfin: support ABORT debug insnMike Frysinger2010-09-221-1/+1
| | | | | | | | There is a pseudo debug insn named ABORT that is commonly used in simulation, so support it in the assembler too. The disassembler already supports it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
