2021-01-09sim: sh64: delete portMike Frysinger1-0/+7
Support for sh64 was dropped from bfd et al in 2018. Without that, the sim port is useless. So clean up this code too.
2021-01-09sim: clean up stale AC_PREREQ refsMike Frysinger1-0/+4
This was purged from the tree when we upgraded to autoconf-2.69, but a few references in the sim tree were missed.
2021-01-08sim: require a C11 compilerMike Frysinger1-0/+4
With GDB requiring a C++11 compiler now, this hopefully shouldn't be a big deal. It's been 10 years since C11 came out, so should be plenty of time to upgrade. This will allow us to start cleaning up random header logic and many of our non-standard custom types.
2021-01-07sim: ChangeLog: move arch-specific entries into the arch dirMike Frysinger1-490/+0
We don't want arch-specific entries in the common ChangeLog files. Most arches do this already, so clean up the recent additions, and move some older entries down to help avoid confusing newcomers.

2020-09-08bpf: simulator: correct div, mod insn semanticsDavid Faust1-0/+5
The div and mod eBPF instructions are unsigned, but the semantic specification for the simulator incorrectly used signed operators. Correct them to unsigned versions, and correct the ALU tests in the simulator (which incorrectly assumed signed semantics). Tested in bpf-unknown-none. cpu/ChangeLog: 2020-09-08 David Faust <david.faust@oracle.com> * bpf.cpu (define-alu-instructions): Correct semantic operators for div, mod to unsigned versions. sim/ChangeLog: 2020-09-08 David Faust <david.faust@oracle.com> * bpf/sem-be.c: Regenerate. * bpf/sem-le.c: Likewise. sim/testsuite/ChangeLog: 2020-09-08 David Faust <david.faust@oracle.com> * sim/bpf/alu.s: Correct div and mod tests. * sim/bpf/alu32.s: Likewise.
2020-09-03bpf: several small fixes in the simulatorJose E. Marchesi1-0/+9
This patch fixes the following problems: - Missing includes in several files leading to implicit function declarations. - Missing prototype for bpf_trace_printk in bpf-helpers.h - The simulator bitsize was set to 32 bits, causing truncation of the program counter. Tested in bpf-unknown-none. sim/ChangeLog: 2020-09-03 Jose E. Marchesi <jose.marchesi@oracle.com> * bpf/bpf.c: Include bpf-helpers.h. * bpf/bpf-helpers.h: Provide a prototype for bpf_trace_printk. * bpf/configure.ac: Set simulator bitsize to 64. * bpf/configure (includedir): Regenerate. * bpf/sim-if.c: Include stdlib.h. * bpf/traps.c: Likewise.
2020-09-03sim: better handle builds of primary targets lacking simsJose E. Marchesi1-0/+6
When building with a primary target that doesn't feature a simulator, one would expect for nothing to be done in sim/. However, a $(top_builddir)/sim/testsuite directory is created, with a Makefile containing a rule like: check-DEJAGNU: site.exp echo "Dejagnu-checking in `pwd` directory ..." rootme=`pwd`; export rootme; echo rootme = $$rootme; \ srcdir=`cd ${srcdir}; pwd`; export srcdir ; echo srcdir = $$srcdir; \ EXPECT=${EXPECT} ; export EXPECT ; echo EXPECT = $$EXPECT; \ if [ -f $$rootme/../../expect/expect ]; then \ TCL_LIBRARY=`cd $$srcdir/../../tcl/library && pwd`; \ export TCL_LIBRARY; \ fi; \ echo TCL_LIBRARY = $$TCL_LIBRARY; \ runtest=$(RUNTEST); echo runtest = $$runtest; \ if $(SHELL) -c "$$runtest --version" > /dev/null 2>&1; then \ $$runtest $(RUNTESTFLAGS); \ else echo "WARNING: could not find \`runtest'" 1>&2; :;\ fi Consequently, when `make check' recurses into sim/testsuite, the above rule is executed. Until now, the desired effect (of doing nothing) was achieved because `runtest --version' fails due to a malformed site.exp being generated in objdir: it is malformed because the primary target doesn't configure a $sim_arch. i.e. this was doing the right thing just by chance. However, the git version of dejagnu seems to have changed in a way runtest doesn't try to load site.exp when it gets --version. The net effect is that the rule above tries to actually run the tests, failing miserably. This little patch makes sim/configure to not recurse into sim/testsuite if the primary target didn't configure a simulator. Tested with: - A simulator target (bpf-unkonwn-none). - A simulator-less target (x86_64-linux-gnu). - A simulator-less target and --build-targets=all. sim/ChangeLog: 2020-09-03 Jose E. Marchesi <jose.marchesi@oracle.com> * configure.ac: Do not configure sim/testsuite nor sim/igen if the primary target doesn't have a simulator. * configure: Regenerate.

2019-09-19bfd_section_* macrosAlan Modra1-0/+8
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2018-12-06sim/opcodes: Allow use of out of tree cgen source directoryAndrew Burgess1-0/+12
When configuring with '--enbale-cgen-maint' the default for both the opcodes/ and sim/ directories is to assume that the cgen source is within the binutils-gdb source tree as binutils-gdb/cgen/. In the old cvs days, this worked well, as cgen was just another sub-module of the single cvs repository and could easily be checked out within the binutils-gdb directory, and managed by cvs in the normal way. Now that binutils-gdb is in git, while cgen is still in cvs, placing the cgen respository within the binutils-gdb tree is more troublesome, and it would be nice if the two tools could be kept separate. Luckily there is already some initial code in the configure.ac files for both opcodes/ and sim/ to support having cgen be located outside of the binutils-gdb tree, however, this was speculative code written imagining a future where cgen would be built and installed to some location. Right now there is no install support for cgen, and so the configure code in opcodes/ and sim/ doesn't really do anything useful. In this commit I repurpose this code to allow binutils-gdb to be configured so that it can make use of a cgen source directory that is outside of the binutils-gdb tree. With this commit applied it is now possible to configure and build binutils-gdb like this: /path/to/binutils-gdb/src/configure --enable-cgen-maint=/path/to/cgen/src/cgen/ make all-opcodes make -C opcodes run-cgen-all Just in case anyone is still using cgen inside the binutils-gdb tree, I have left the default behaviour of '--enable-cgen-maint' (with no parameter) unchanged, that is it looks for the cgen directory as 'binutils-gdb/cgen/'. opcodes/ChangeLog: * configure.ac (enable-cgen-maint): Support passing path to cgen source tree. * configure: Regenerate. sim/ChangeLog: * common/acinclude.m4 (enable-cgen-maint): Support passing path to cgen source tree. * cris/configure: Regenerate. * frv/configure: Regenerate. * iq2000/configure: Regenerate. * lm32/configure: Regenerate. * m32r/configure: Regenerate. * or1k/configure: Regenerate. * sh64/configure: Regenerate.

2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi1-0/+5
When trying to run the update-gnulib.sh script in gdb, I get this: Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1. Aborting. Apparently, it's an issue with a regex in automake that triggers a warning starting with Perl 5.22. It has been fixed in automake 1.15.1. So I think it's a good excuse to bump the versions of autoconf and automake used in the gnulib import. And to avoid requiring multiple builds of autoconf/automake, it was suggested that we bump the required version of those tools for all binutils-gdb. For autoconf, the 2.69 version is universally available, so it's an easy choice. For automake, different distros and distro versions have different automake versions. But 1.15.1 seems to be the most readily available as a package. In any case, it's easy to build it from source. I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ, because I don't think they are useful in our case. They only specify a lower bound for the acceptable version of automake/autoconf. That's useful if you let the user choose the version of the tool they want to use, but want to set a minimum version (because you use a feature that was introduced in that version). In our case, we force people to use a specific version anyway. For the autoconf version, we have the check in config/override.m4 that enforces the version we want. It will be one less thing to update next time we change autotools version. I hit a few categories of problems that required some changes. They are described below along with the chosen solutions. Problem 1: configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see: configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation Solution 1: Adjust the code based on the example at that URL. Problem 2 (in zlib/): Makefile.am: error: required file './INSTALL' not found Makefile.am: 'automake --add-missing' can install 'INSTALL' Makefile.am: error: required file './NEWS' not found Makefile.am: error: required file './AUTHORS' not found Makefile.am: error: required file './COPYING' not found Makefile.am: 'automake --add-missing' can install 'COPYING' Solution 2: Add the foreign option to AUTOMAKE_OPTIONS. Problem 3: doc/Makefile.am:20: error: support for Cygnus-style trees has been removed Solution 3: Remove the cygnus options. Problem 4: Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS') Solution 4: Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is already defined earlier). Problem 5: doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 5: Rename .texinfo files to .texi. Problem 6: doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 6: Remove the hack at the bottom of doc/Makefile.am and use the info-in-builddir automake option. Problem 7: doc/Makefile.am:35: error: required file '../texinfo.tex' not found doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex' Solution 7: Use the no-texinfo.tex automake option. We also have one in texinfo/texinfo.tex, not sure if we should point to that, or move it (or a newer version of it added with automake --add-missing) to top-level. Problem 8: Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory, Makefile.am:131: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. Solution 8: Use subdir-objects, that means adjusting references to some .o that will now be in config/.

2016-01-09sim: stop configuring common subdirMike Frysinger1-0/+7
Now that cconfig.h doesn't exist, there's no need to build in the common subdir anymore. We leave the configure/Makefile files in there as there is a helper for developers to generate the nltvals.def file. Once that gets cleaned up in the future though, we can drop the build logic too.
2016-01-09sim: drop common/cconfig.h in favor of a single config.hMike Frysinger1-0/+4
The common subdir sets up a cconfig.h file to hold checks for the common code. In practice, most files still end up using config.h instead which just leads to confusion. Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON so we can drop the cconfig.h file altogether. Now there is only a single config.h file like normal.

2015-12-26sim: punt WITH_DEVICES & tconfig.h supportMike Frysinger1-0/+4
No arch is using this anymore, and we want all new ports using the hardware framework instead. Punt WITH_DEVICES and the two callbacks device_io_{read,write}_buffer. We can also punt the tconfig.h file as no port is using it anymore. This fixes in-tree builds that get confused by picking up the wrong one (common/ vs <port>/) caused by commit ae7d0cac8ce971f7108d270c. Any port that needs to set up a global define can use their own sim-main.h file that they must provide regardless.
