* sim/common: wire up new unordered comparisonsStafford Horne2019-06-133-0/+33
| | | | | | | | | | | | | | | Define and wire up unordered floating point comparison operations for cgen targets. This patch depends on my posted cgen patches[0]. [0] https://www.sourceware.org/ml/cgen/2019-q2/msg00013.html sim/common/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * cgen-accfp.c (unorderedsf, unordereddf): New functions. (cgen_init_accurate_fpu): Wire up unorderedsf and unordereddf. * cgen-fpu.h (cgen_fp_ops): Define fields unorderedsf and unordereddf.
* sim/common: Wire in df/di conversionStafford Horne2019-06-132-0/+29
| | | | | | | | | | Up until now these have not been used in any CGEN targets, add them as they are now used by OpenRISC. sim/common/ChangeLog: * cgen-accfp.c (floatdidf, fixdfdi): New functions. (cgen_init_accurate_fpu): Add floatdidf and fixdfdi.
* sim: Use host not target byte order for merging and splitting valuesAndrew Burgess2019-04-132-5/+14
| | | | | | | | | | | | | | | | | | | | | | When using writes to memory through a struct to merge and extract multi-word value, it is the endianness of the host, not the target that affects which order the component words need to be written into the structure. Of the 5 functions adjusted here 4 of them are unused. The 5th, JOINSIDF will soon be used by the or1k target. For or1k, simulated on x86-64, this change fixes this function so that the correct bytes are now returned. sim/common/ChangeLog: * cgen-ops.h (SUBWORDXFSI): Compare HOST_BYTE_ORDER not CURRENT_TARGET_BYTE_ORDER. (SUBWORDTFSI): Likewise. (JOINSIDF): Likewise. (JOINSIXF): Likewise. (JOINSITF): Likewise.
* sim: fix all sim buildsAndrew Burgess2019-03-283-0/+8
| | | | | | | | | | | | | | | | | | | | | This commit: commit ef9866970ce6683d40465fb7c3168f87a1dcd1b7 Date: Thu Mar 28 06:40:30 2019 +0900 sim/common: convert sim-arange to use sim-inline broke many simulator targets. I fixed aarch64 in a previous commit without realising how many other target were also broken. This commit adds the missing includes (sim-assert.h and libiberty.h), which seem to be needed by many simulator targets, in a central location, this should fix most builds. sim/common/ChangeLog: * sim-base.h: Add 'sim-assert.h' include. * sim-basics.h: Add 'libiberty.h' include.
* sim/common: Fix warnings: "warning: implicit declaration of function..."Stafford Horne2019-03-287-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During building of several cgen simulator's I notices the below warnings. Adding includes fixes these. Including config.h allows stdio.h to properly configure itself to expose asprintf(). The other warnings for abort, free, memset, strlen are trivial.

* Fix the sim buildTom Tromey2019-01-263-2/+45
| | | | | | | | | | | | | | | | | | | | | | Simon pointed out that the "common/" include change in gdb broke the sim build. The problem was that the sim was using gdb's create-version.sh, which changed. This patch copies create-version.sh to the sim, so that it can generate "version.c" in a way that works in the sim build. Tested by rebuilding. sim/common/ChangeLog 2019-01-26 Tom Tromey <tom@tromey.com> * Make-common.in (version.c): Use sim's create-version.sh. * create-version.sh: New file. sim/ppc/ChangeLog 2019-01-26 Tom Tromey <tom@tromey.com> * Makefile.in (version.c): Use sim's create-version.sh.

| | | | | | | | | | | | | | | | This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
* sim: Don't overwrite stored errno in sim_syscall_multiAndrew Burgess2018-12-182-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The host syscall callback mechanism should take care of updating the errcode within the CB_SYSCALL struct, and we should not be adjusting the error code once the syscall has completed. We especially, should not be rewriting the syscall errcode based on the value of errno some time after running the host syscall, as there is no guarantee that errno has not be overwritten. To perform a syscall we call cb_syscall (in syscall.c). To return from cb_syscall control passes through one of two exit paths these are labeled FinishSyscall and ErrorFinish and are reached using goto statements scattered throughout the cb_syscall function. In FinishSyscall we store the syscall result in 'sc->result', and the error code is transated to target encoding, and stored in 'sc->errcode'. In ErrorFinish, we again store the syscall result in 'sc->result', and fill in 'sc->errcode' by fetching the actual errno from the host with the 'cb->get_errno' callback. In both cases 'sc->errcode' will have been filled in with an appropriate value. Further, if we look at a specific syscall example, CB_SYS_open, in this case the first thing we do is fetch the path to open from the target with 'get_path', if this fails then the errcode is returned, and we jump to FinishSyscall. Notice that in this case, no host syscall may have been performed, for example a failure to read the path to open out of simulated memory can return EINVAL without performing any host syscall. Given that no host syscall has been performed, reading the host errno makes absolutely no sense. This commit removes from sim_syscall_multi the rewriting of sc->errcode based on the value of errno, and instead relies on the value stored in the cb_syscall. sim/common/ChangeLog: * sim-syscall.c (sim_syscall_multi): Don't update sc->errcode at this point, it should have already been set in cb_syscall.
* sim/opcodes: Allow use of out of tree cgen source directoryAndrew Burgess2018-12-061-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Change "xor" name in cpu_core to allow building with iso646.h or C++ compilerКомпан, Вячеслав Олегович2018-09-283-4/+14
| | | | | | | | | | | | | | | | | | This code was introduced back in 1998, and C99 appeared next year, defining the `xor` as an 'alternative keyword' if iso646.h is included. Moreover, C++98 defines it on the language level. As a result, the code is not buildable with C++ compiler or if iso646.h is included beforehand. According to comment, `sim_cpu_core` is mostly a clone of `sim_core`, so I renamed it to `byte_xor` as it's called in `sim_core`. sim/common/ChangeLog: * sim-core.h (sim_cpu_core): Rename cpu_core.xor to cpu_core.byte_xor. * sim-core.c (sim_core_set_xor): Likewise.

* Bump to autoconf 2.69 and automake 1.15.1Simon Marchi2018-06-193-265/+342
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Refactor disassembler selectionYao Qi2017-05-242-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nowadays, opcodes/disassemble.c:disassembler selects the proper disassembler according to ABFD only. However, it actually selects disassemblers according to arch, mach, endianess, and abfd. This patch adds them to the parameters of disassembler, so that its caller can still select disassemblers in case that abfd is NULL (a typical case in GDB). There isn't any functionality change. binutils: 2017-05-24 Yao Qi <yao.qi@linaro.org> * objdump.c (disassemble_data): Caller update. include: 2017-05-24 Yao Qi <yao.qi@linaro.org> * dis-asm.h (disassembler): Update declaration. opcodes: 2017-05-24 Yao Qi <yao.qi@linaro.org> * disassemble.c (disassembler): Add arguments a, big and mach. Use them. sim/common: 2017-05-24 Yao Qi <yao.qi@linaro.org> * sim-trace.c (trace_disasm): Caller update.

* sim: unify symbol table handlingMike Frysinger2016-08-154-26/+83
| | | | | | | | The common sim tracing code already handles loading and tracking of symbols from the target program so that it can show symbol info in trace/disassembly calls. Once we touch up the trace code and add a few API callbacks, ports don't need to do loading and searching of symbol tables themselves anymore.
* sim: cgen: constify mode_namesMike Frysinger2016-08-133-2/+7

* sim: cgen: drop unused argv/envp definitionsMike Frysinger2016-08-132-8/+5

* Minor comment fixes in sim/common/sim-fpu.c.Joel Brobecker2016-01-172-67/+71
| | | | | | | | | | | This patch makes a fair number of fixes in the various comments of sim-fpu.c, mostly to either better conform to the GNU Coding Standards (sentences start with a capital letter, end with a period), or to fix spelling mistakes. sim/common/ChangeLog: * sim-fpu.c: Minor comment fixes throughout.
* minor reformatting in sim/common/sim-fpu.c.Joel Brobecker2016-01-172-2/+9
| | | | | | | | | | This patch just makes a copy of formatting changes to better conform with the GNU Coding Style. sim/common/ChangeLog: * sim-fpu.c (print_bits): Minor reformatting (no code change). (sim_fpu_map): Likewise.
* sim: config: do not try to align settingsMike Frysinger2016-01-112-5/+10
| | | | | We try to align the output for a few settings, but not most of them. Drop the aligning entirely to be lazy.
* sim: move many common settings from CPPFLAGS to config.hMike Frysinger2016-01-107-150/+104
| | | | | | | | | Rather than stuffing the command line with a bunch of -D flags, start moving things to config.h which is managed by autoheader. This makes the makefile a bit simpler and the build output tighter, and it makes the migration to automake easier as there are fewer vars to juggle. We'll want to move the other options out too, but it'll take more work.
* sim: drop unused SIM_AC_OPTION_PACKAGESMike Frysinger2016-01-104-30/+7
| | | | | | | | This was imported from the ppc sim, but that was only used to control a single file, and that is already governed by the hw models. There's no need to have a sep configure option here, especially since none of the other sims are using it. Even when the code is enabled, there's no runtime overhead.
* sim: allow the environment configure option everywhereMike Frysinger2016-01-102-0/+5
| | | | | | | Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
* sim: allow the assert configure option everywhereMike Frysinger2016-01-102-0/+5
| | | | | | | Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order to make the configure flag available, which none of them do. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports.
* sim: drop targ-vals.def->nltvals.def indirectionMike Frysinger2016-01-105-18/+16
| | | | | | | | | | | We don't have alternative nltvals.def files, so always symlinking the targ-vals.def file to it doesn't gain us anything. It does make the build more complicated though and a pain to convert to something newer (like automake). Drop the symlinking entirely. In the future, we'll want to explode this file anyways into the respective arch dirs so things can be selected dynamically at runtime, so it's not like we'll be bringing this back.
* sim: allow the inline configure option everywhereMike Frysinger2016-01-102-15/+10
| | | | | | | Currently ports have to call SIM_AC_OPTION_INLINE explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
* sim: drop --enable-sim-{regparm,stdcall} optionsMike Frysinger2016-01-106-192/+49
| | | | | | | These options were never exposed for most sims (just the ppc one), and they are really only useful on 32-bit x86 systems. Considering modern systems tend to be 64-bit x86_64 and how well modern compilers are at optimizing code, these have outlived their usefulness.
* sim: drop --enable-sim-cflags optionMike Frysinger2016-01-104-19/+8
| | | | | | | | | | No other sub directory provides such a configuration option, so drop it from the sim dir as well. This cleans up a good bit of code in the process. If people want to use custom flags for just the sim, they can still run configure+make by hand in the sim subdir and use the normal CFLAGS settings.
* sim: drop common/cconfig.h in favor of a single config.hMike Frysinger2016-01-0915-10590/+81
| | | | | | | | | | 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.
* sim: config: drop use of __DATE__/__TIME__Mike Frysinger2016-01-062-7/+5
| | | | | These don't add a whole lot of useful info, and people don't like them as it makes builds unreproducible, so just drop them.
* sim: sim_{create_inferior,open,parse_args}: constify argv/env slightlyMike Frysinger2016-01-063-2/+7
| | | | | | | 2016-01-03 Mike Frysinger <vapier@gentoo.org> * sim-options.c (sim_parse_args): Mark argv array const. * sim-options.h (sim_parse_args): Likewise.
* sim: trace: add support for disassemblingMike Frysinger2016-01-053-1/+119
| | | | | | Some targets have started to add support for calling the disassembler automatically when executing code. Add support for that directly into the trace core.
* sim: use STATE_MAGIC helperMike Frysinger2016-01-042-1/+5

* sim: unify min/max macrosMike Frysinger2016-01-045-9/+17
| | | | | Import defines from gdb/defs.h to the sim core so we can delete the various copies that already exist.
* sim: parse_args: polish getopt error messageMike Frysinger2016-01-042-1/+5
| | | | | | The cris sim hit a few failures after the recent getopt logic, and the expected output showed a few ways we can improve things to better match other utils.
* sim: punt x86-specific bswap logicMike Frysinger2016-01-045-55/+12
| | | | | | | The compiler/C library should produce reasonable code for htonl/ntohl, and at least glibc tries pretty hard to always produce good code for them. This logic only had support for 32-bit x86 systems anymore, and it's unlikely people were even opting into this, so drop it all.
* sim: parse_args: display getopt error ourselvesMike Frysinger2016-01-032-1/+33
| | | | | | Fix a long standing todo where we let getopt write directly to stderr when an invalid option is passed. Use the sim io funcs instead as they go through the filtered callbacks that gdb wants.
* sim: clean up some more device detritusMike Frysinger2016-01-033-4/+5
| | | | | | | | Clean up some more remains of WITH_DEVICES that escaped notice. We also clean up GETTWI/SETTWI defines in a few ports where they were copied & pasted and are unused as they happen to be near the device code.
* sim: use libiberty countargv in more placesMike Frysinger2016-01-032-2/+6
| | | | | A bunch of places open code the countargv implementation, or outright duplicate it (as count_argc). Replace all of those w/countargv.
