2024-07-19bfin: drop _ASSIGN_BANGJan Beulich1-1/+0
A few testcases demonstrate that "=!" isn't supposed to be an individual token, since "= !" is used in a number of places. So far lexing that to a single token worked because of the scrubber being overly aggressive in removing whitespace. As that's going to change, replace uses by separate ASSIGN and BANG.
2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.
2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
2022-02-16gas local label and dollar label handlingAlan Modra1-2/+2
Much of the gas source and older BFD source use "long" for function parameters and variables, when other types would be more appropriate. This patch fixes one of those cases. Dollar labels and numeric local labels do not need large numbers. Small positive itegers are usually all that is required. Due to allowing longs, it was possible for fb_label_name and dollar_label_name to overflow their buffers. * symbols.c: Delete unnecessary forward declarations.

2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

2021-02-24PR23691, gas .y files vs. automatic make dependenciesAlan Modra1-1/+1
A number of targets, bfin, rl78, rx, can show odd failures when bfd/reloc.c changes BFD_RELOC_* enum values, if recompiling over a build dir with existing objects. The problem is caused by bfin-parse.o and similar not being recompiled and so using stale BFD_RELOC_* values. This isn't fixed by making bfin-parse.c depend on bfd/reloc.c, which isn't necessary anyway. bfin-parse.o should have been recompiled due to bfd/bfd.h changing when extracted bfd/reloc.c BFD_RELOC_* values change, but that wasn't happening. The problem is that automake generates a makefile that loads gas/config/.deps/ dependency file for objects with corresponding sources mentioned in EXTRA_as_new_SOURCES. Unless we want to mess around generating explicit dependencies, I think that mean moving some object files to the build gas/config/. This patch does that, removing some hacks for m68k-parse.c that should no longer be necessary, and removes some rules that catered to old bison producing code that triggers compiler warnings. PR 23691 * Makefile.am (TARGET_CPU_CFILES): Split off config/xtensa-relax.c.. (TARGET_CPU_HFILES): ..and config/xtensa-relax.h.. (TARGET_EXTRA_FILES): ..to here.

2011-02-13gas/opcodes: blackfin: punt BYTEOP2M insn supportMike Frysinger1-1/+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>
2010-10-11gas: blackfin: reign in overeager insn flag handlingMike Frysinger1-7/+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>

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>

2010-09-22gas: blackfin: support ABORT debug insnMike Frysinger1-1/+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>
