* [Patch][binutils][aarch64] .bfloat16 directive for AArch64 [7/10]Matthew Malcomson2019-11-075-0/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, This patch is part of a series that adds support for Armv8.6-A (Matrix Multiply and BFloat16 extensions) to binutils. This patch implements the '.bfloat' directive for the AArch64 backend. The syntax for the directive is: .bfloat16 <0-n numbers> e.g. .bfloat16 12.0 .bfloat16 0.123, 1.0, NaN, 5 This is implemented by utilizing the ieee_atof_detail function in order to encode the slightly different bfloat16 format.

* [Patch][binutils][arm] Create a new generic coprocessor array [3/10]Matthew Malcomson2019-11-072-51/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, This patch is part of a series that adds support for Armv8.6-A (Matrix Multiply and BFloat16 extensions) to binutils. Some generic instructions match a large range of encoding space (e.g. stc, mcr, mrc). Currently these instructions are in the coprocessor_opcodes array, which means they are checked before many other instructions when disassembling arm and thumb32 codes. This patch moves the generic instructions into a separate array to be checked later on. This is done in order to avoid instruction conflict between the generic instructions and newer ones -- this has already been seen with MVE, and is also a problem with BFloat16. One way to avoid the conflict could be to swap the search order between coprocessor_opcodes and neon_opcodes. We avoid this since it's a larger change that may introduce extra bugs (that aren't caught by the testsuite). We have decided against searching the generic array after searching the arm specific and thumb32 specific arrays with a similar reasoning about keeping the change small. Regression tested with arm-none-linux-gnueabihf. Committed on behalf of Mihail Ionescu. opcodes/ChangeLog: 2019-10-29 Mihail Ionescu <mihail.ionescu@arm.com> 2019-10-29 Matthew Malcomson <matthew.malcomson@arm.com> * arm-dis.c (print_insn_coprocessor, print_insn_generic_coprocessor): Create wrapper functions around the implementation of the print_insn_coprocessor control codes.

(print_insn_arm): Use both print_insn_coprocessor and print_insn_generic_coprocessor. (print_insn_thumb32): As above. Is it ok for trunk? Regards, Mihail

For: ... $ ./gdb/contrib/words.sh $(find gdb -type f -name "*.c" -o -name "*.h") ... it generates a list of ~15000 words prefixed with frequency. This could be used to generate a dictionary that is kept as part of the sources, against which new code can be checked, generating a warning or error. The hope is that misspellings would trigger this frequently, and rare words rarely, otherwise the burden of updating the dictionary would be too much. And for: ... $ ./gdb/contrib/words.sh -f 1 $(find gdb -type f -name "*.c" -o -name "*.h") ... it generates a list of ~5000 words with frequency 1. This can be used to scan for misspellings manually.

* Remove CR16C supportAlan Modra2019-11-0724-1532/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I think it is past time to remove CR16C support. CR16C was added in 2004, and only for ld. gas and binutils support is lacking, and there have been no commits to bfd/elf32-cr16c.c other than warning fixes or global maintainers making changes to all targets. I see no maintainer listed for CR16C, and no commits from anyone at NSC supporting the target. Furthermore, at the time the CR16 support was added in 2007, config.sub was changed upstream to no longer recognise cr16c as a valid cpu. That means the CR16C ld support is only available as a secondary target by configuring with, for example, --enable-targets=all or --enable-targets=cr16c-unknown-elf. No testing of the CR16C target is possible. include/ * elf/cr16c.h: Delete. bfd/ * cpu-cr16c.c: Delete. * elf32-cr16c.c: Delete. * Makefile.am, * archures.c, * config.bfd, * configure.ac, * reloc.c, * targets.c: Remove cr16c support. * Makefile.in, * bfd-in2.h, * configure, * libbfd.h, * po/SRC-POTFILES.in: Regenerate. ld/ * emulparams/elf32cr16c.sh: Delete. * scripttempl/elf32cr16c.sc: Delete. * Makefile.am, * configure.tgt: Remove cr16c support. * NEWS: Mention removal of cr16c. * Makefile.in, * po/BLD-POTFILES.in: Regenerate.

The comment about keeping architecture variants together seems odd to me, and is no doubt the reason why ix86 and x86_64 were grouped together, so I removed that comment. The patch doesn't change order of entries for a given cpu. * configure.tgt: Order targets by cpu.

| | | | | | | | | | As the comments (here: almost, in the opcode table: fully) correctly state - all register operands except MONITOR's address one are fixed at 32 bit size. Don't print 64-bit registers there. Also adjust x86-64-suffix.d's name such that it wouldn't be identical to x86-64-rep-suffix.d's, but instead resemble that of its sibling x86-64-suffix-intel.d.

* Style disassembly in the TUITom Tromey2019-11-056-142/+205
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the TUI disassembly window to style its contents. The styling should be identical to what is seen in the CLI. This involved a bit of rearrangement, so that the source and disassembly windows could share both the copy_source_line utility function, and the ability to react to changes in "set style enabled". This version introduces a new function to strip the styling from the address string when computing the length. As a byproduct, it also removes the unused "insn_size" computation from tui_disasm_window::set_contents. gdb/ChangeLog 2019-11-05 Tom Tromey <tom@tromey.com> * tui/tui-source.h (struct tui_source_window): Inline constructor.

* GENERATE_SHLIB_SCRIPT vs. EMBEDDED.Alan Modra2019-11-0515-18/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A target that sets EMBEDDED non-empty is one that doesn't want to put the ELF file header or program header in a memory image. Likely the target isn't interested in supporting dynamically loaded executables, shared libraries, or PIEs, because loaders for such binaries generally require program headers to be present. This isn't 100% true though. The target might be one where the loader accesses the file system in order to retrieve headers. Also, note that not all "shared libraries" require gcc -shared or the shared library support in the linker. I believe one implementation of shared libraries on uclinux is like this. So, this patch removes GENERATE_SHLIB_SCRIPT and GENERATE_PIE_SCRIPT in most emulparams files where EMBEDDED is set, restoring the shared lib and pie support in emulparams files that unset EMBEDDED after including a file where the support is removed. Exceptions to the general rule that EMBEDDED disables shared libs are: arm*-*-symbianelf*, where the OS wants shared library support without ELF program headers in the image, and sh*-*-uclinux*, where I've left things as they were, ie. both EMBEDDED and GENERATE_SHLIB_SCRIPT because I'm unsure as to the shared library scheme. * emulparams/aarch64elf.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Don't set. * emulparams/aarch64elf32.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Don't set. * emulparams/arcelf.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/armelf.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Don't set. * emulparams/armelf_fbsd.sh (GENERATE_SHLIB_SCRIPT): Set. * emulparams/armelf_nbsd.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Set. * emulparams/armelf_vxworks.sh (GENERATE_SHLIB_SCRIPT): Set. * emulparams/armsymbian.sh (GENERATE_SHLIB_SCRIPT): Set. * emulparams/elf32bfin.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/elf32microblaze.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/score3_elf.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/shelf.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/shelf_nbsd.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Set. * emulparams/shelf_uclinux.sh (GENERATE_SHLIB_SCRIPT): Set.

* Obsolete Solaris 10 supportRainer Orth2019-11-045-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's the patch corresponding to the Solaris 10 obsoletion announcement https://sourceware.org/ml/gdb/2019-10/msg00008.html Right now it doesn't remove any code, but obviates the need to test on that ancient platform. Besides, some of the patches I have in my queue would require different solutions for Solaris 10 and 11. There are a few comment-only references that I've kept since they are still correct as is, even when GDB doesn't support Solaris 10 any longer. The only code fragment I've left in is support for /proc/<pid/path/a.out in procfs.c (procfs_target::pid_to_exec_file): while current Solaris 11 updates provide /proc/<pid>/execname, that wasn't present in Solaris 11.0 and still isn't in current Illumos and I didn't want to make live harder for them.
