Jeff Law	477904ca75	Fix for v850e divq instruction This is the last of the correctness fixes I've been carrying around for the v850. Like the other recent fixes, this is another case where we haven't been as careful as we should WRT host vs target types. For the divq instruction both operands are 32 bit types. Yet in the simulator code we convert them from unsigned int to signed long by assignment. So 0xfffffffb (aka -5) turns into 4294967291 and naturally that changes the result of our division. The fix is simple, insert a cast to int32_t to force interpretation as a signed value. Testcase for the simulator is included. It has a trivial dependency on the bins patch.	4 years ago
Jeff Law	49fffa58f7	Fix "bins" simulation for v850e3v5 I've been carrying this for a few years. One test in the GCC testsuite is failing due to a bug in the handling of the v850e3v5 instruction "bins". When the "bins" instruction specifies a 32bit bitfield size, the simulator exhibits undefined behavior by trying to shift a 32 bit quantity by 32 bits. In the case of a 32 bit shift, we know what the resultant mask should be. So we can just set it. That seemed better than using 1UL for the constant (on a 32bit host unsigned long might still just be 32 bits) or needlessly forcing everything to long long types. Thankfully the case where this shows up is only bins <src>, 0, 32, <dest> which would normally be encoded as a simple move. * testsuite/v850/allinsns.exp: Add v850e3v5. * testsuite/v850/bins.cgs: New test. * v850/simops.c (v850_bins): Avoid undefined behavior on left shift.	4 years ago
Andrew Burgess	7b01c1cc1d	sim: fixes for libopcodes styled disassembler In commit: commit `60a3da00bd` Date: Sat Jan 22 11:38:18 2022 +0000 objdump/opcodes: add syntax highlighting to disassembler output I broke several sim/ targets by forgetting to update their uses of the libopcodes disassembler to take account of the new styled printing. These should all be fixed by this commit. I've not tried to add actual styled output to the simulator traces, instead, the styled print routines just ignore the style and print the output unstyled.	4 years ago

Nick Alcock	caf606c90d	libtool.m4: fix the NM="/nm/over/here -B/option/with/path" case My previous nm patch handled all cases but one -- if the user set NM in the environment to a path which contained an option, libtool's nm detection tries to run nm against a copy of nm with the options in it: e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle". This is unlikely to be desirable: in this case we should run "/usr/bin/nm --blargle /usr/bin/nm". Furthermore, as part of this nm has to detect when the passed-in $NM contains a path, and in that case avoid doing a path search itself. This too was thrown off if an option contained something that looked like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run "nm -B../prev-gcc nm" which rarely works well (and indeed it looks to see whether that nm exists, finds it doesn't, and wrongly concludes that nm -p or whatever does not work). Fix all of these by clipping all options (defined as everything including and after the first " -") before deciding whether nm contains a path (but not using the clipped value for anything else), and then removing all options from the path-modified nm before looking to see whether that nm existed. NM=my-nm now does a path search and runs e.g. /usr/bin/my-nm -B /usr/bin/my-nm NM=/usr/bin/my-nm now avoids a path search and runs e.g. /usr/bin/my-nm -B /usr/bin/my-nm NM="my-nm -p../wombat" now does a path search and runs e.g. /usr/bin/my-nm -p../wombat -B /usr/bin/my-nm NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search: ../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm This seems to be all combinations, including those used by GCC bootstrap (which, before this commit, fails to bootstrap when configured --with-build-config=bootstrap-lto, because the lto plugin is now using --export-symbols-regex, which requires libtool to find a working nm, while also using -B../prev-gcc to point at the lto plugin associated with the GCC just built.) Regenerate all affected configure scripts. * libtool.m4 (LT_PATH_NM): Handle user-specified NM with options, including options containing paths.	5 years ago

Hans-Peter Nilsson	e63f65fea9	sim/testsuite: Default global_cc_os and global_cc_works properly There was an omission on `3e6dc39ed7` "sim/testsuite: Set global_cc_os also when no compiler is found"; global_cc_os wasn't set for other than the primary target, which means that the "unguarded" use of global_cc_os in testsuite/cris/c/c.exp caused the dreaded "ERROR: can't read "global_cc_os": no such variable" when e.g. configuring for pru-elf and doing "make check-sim". Better initializing both variables at the top to default values, rather than adding another single 'set global_cc_os ""', to reduce the risk of not setting them properly if or when that if-statement-chain is made longer. sim/testsuite: * lib/sim-defs.exp (sim_init_toolchain): Default global_cc_os and global_cc_works properly, before if-chain.	5 years ago
Hans-Peter Nilsson	234f5865fa	sim/testsuite/cris: If failing compilation, mark C tests as errors ...when we know we have a working compiler. This will reduce the risk of faulty edits by exposing them rather than hiding them as "unresolved". It also harmonizes behavior with that of run_sim_test. * c/c.exp: Mark C tests failing compilation test errors.	5 years ago
Hans-Peter Nilsson	4b0e74fd18	sim/testsuite/cris: Remove faulty use of basename in C tests Calls to basename were added here as part of commit `e1e1ae6e9b` "sim: testsuite: fix objdir handling", but that commit missed adding "#include <libgen.h>" or the equivalent GNU extension, see basename(3). Fixing that shows a logical error in the change to openpf1.c; the non-/-prefixed code-path was changed instead of the "/"-prefixed code-path, which is the one executed after that commit. For "newlib" these tests failed linking after that commit. Recent newlib has the (asm-renamed) GNU-extension-variant of basename, but we're better off not using it at all. Unfortunately, compilation failures for C tests run by the machinery in c.exp are currently just marked "unresolved", in contrast to C and assembler tests run by calling run_sim_test. The interaction of calling with the full program-path vs. use of --sysroot exposes a consistency problem: when --sysroot is used, argv[0] isn't the path by which the program can find itself. It's undecided whether argv[0] for the program running in the simulator should be edited (related to the naked argument to the simulator before passing on to the simulated program) to remove a leading --sysroot. Either way, such a change would be out of scope for this commit. * c/stat3.c (mybasename): New macro. Use it instead of basename. * c/openpf1.c: Correct basename-related change and update related comment.	5 years ago

Hans-Peter Nilsson	dc4e1fde36	sim: Fix use of out-of-tree assembler and linker when testing With commit `7a259895bb` "sim: testsuite: expand arch specific toolchain settings", trying to use out-of-tree ld and as at test-time broke for the "primary target", like when testing a release-tarball. Subsequent to that commit, all assembler tests without in-tree-built tools FAIL, getting errors when trying to call $(abs_builddir)/../gas/as-new. But, that isn't the actual culprint; it's actually it's its immediate predecessor, commit `8996c21067` "sim: testsuite: setup per-port toolchain settings for multitarget build", which hardcodes in-tree-paths to those tools instead of considering e.g. $(<X>_FOR_TARGET), the preferred overridable variable for single-target builds, as set up by the toplevel Makefile. This commit calls GCC_TARGET_TOOL (a deceptive name; gcc-specific features aren't used) from toplev/config/acx.m4, somewhat like calls in toplev/configure.ac but without the NCN_STRICT_CHECK_TARGET_TOOLS step, for each X to find a value for $(<X>_FOR_TARGET). N.B.: in-tree tools still override any ${target}-${tool} found in $PATH, i.e. only previously broken builds are affected. The variables $(<X>_FOR_TARGET) are usually overridden by the toplevel Makefile to the same value or better, but has to be set here too, as automake "wants" Makefiles to be self-contained (you get an error pointing out that the variable may be empty). If it hadn't been for that, SIM_AC_CHECK_TOOLCHAIN_FOR_PRIMARY_TARGET would not be needed. This detail should only (positively) affect users invoking "make check" in sim/ instead of "make check-sim" (or "make check") at the toplevel. Now the output from "configure" matches the target tools actually used by sim at test-time, for the "primary target". Using $(CC) for "example-" targets CC_FOR_TARGET is not changed, as that appears to be a deliberate special-case. Note that all tools still have to be installed and present in $PATH at configure-time to be properly used at test-time. sim: * m4/sim_ac_toolchain.m4 (SIM_AC_CHECK_TOOLCHAIN_FOR_PRIMARY_TARGET): New defun. (SIM_TOOLCHAIN_VARS): Call it using AC_REQUIRE, and use variables AS_FOR_TARGET, LD_FOR_TARGET and CC_FOR_TARGET instead of hard-coded values. * Makefile.in, configure: Regenerate.	5 years ago
Hans-Peter Nilsson	e7e980c6fa	sim cris: Unbreak --disable-sim-hardware builds With --disable-sim-hardware (--enable-sim-hardware=no), whose default was changed to --enable-sim-hardware(=yes) in commit `34cf511206`, building for cris-elf fails as sim_hw_parse then doesn't exist. A cris-elf simulator configured for --enable-sim-hardware (or the default after to the mentioned commit) runs about 2.5x slower than one configured --disable-sim-hardware. A further 2-5% performance regression was not investigated. When sim_hw_parse doesn't exist, --cris-900000xx can't be supported. The best action here is to remove it completely, so its absence can be identified through --help, but avoiding littering the code with "#if WITH_HW". sim/cris: * sim-if.c (cris_options) [WITH_HW]: Conditionalize support of option --cris-900000xx. (sim_open) [WITH_HW]: Conditionalize sim_hw_parse call.	5 years ago
Hans-Peter Nilsson	6f62dbfb12	sim/testsuite/cris: As applicable, require simoption --cris-900000xx Apply the new run_sim_test option "require" as in "#require simoption --cris-900000xx" for all tests using that option. This allows a clean test-suite-run for a build with --disable-sim-hardware, where that option is not supported, by skipping those tests as "untested". sim/testsuite/cris: * asm/io1.ms, asm/io2.ms, asm/io3.ms, asm/io6.ms, asm/io7.ms: Call "#require: simoption --cris-900000xx".	5 years ago
Hans-Peter Nilsson	81064d7abc	sim/testsuite: Support "requires: simoption <--name-of-option>" Simulator features can be present or not, typically depending on different-valued configure options, like --enable-sim-hardware[=off\|=on]. To avoid failures in test-suite-runs when testing such configurations, a new predicate is needed, as neither "target", "progos" nor "mach" fits cleanly. The immediate need was to check for presence of a simulator option, but rather than a specialized "requires-simoption:" predicate I thought I'd handle the general (parametrized) need, so here's a generic predicate machinery and a (first) predicate to use together with it; checking whether a particular option is supported, by looking at "run --help" output. This was inspired by the check_effective_target_ machinery in the gcc test-suite. Multiple "requires: <requirement> <parameter>" form a list of predicates (with parameters), to be used as a conjunction. sim/testsuite: * lib/sim-defs.exp (sim_check_requires_simoption): New function. (run_sim_test): Support "requires: <requirement> <parameter>".	5 years ago
Hans-Peter Nilsson	46f238477f	sim/testsuite/cris/hw/rv-n-cris/irq1.ms: Disable due to randomness For reasons that remain largely to be investigated (besides the apparent lack of synchronization between two processes), this test fails randomly, with two different sets of common outputs. Curiously, that doesn't happen for the other similar tests. There's a comment that mentions this, though that doesn't make it a sustainable part of a test-suite. (Known-blinking tests should be disabled until fixed.) sim/testsuite/cris: * hw/rv-n-cris/irq1.ms: Disable by use of a never-matched "progos" value.	5 years ago
Hans-Peter Nilsson	56ba3848dc	sim/testsuite/cris/c: Use -sim3 but only for newlib targets Commit `a39487c668` "sim: cris: use -sim with C tests for cris-elf targets" caused " -sim" to be appended to CFLAGS_FOR_TARGET for cris--elf, where testing had until then relied on "RUNTESTFLAGS=--target_board=cris-sim" being passed when running "make check-sim", adding the right options. While "-sim" happens to work, the baseboard-file cris-sim.exp uses "-sim3" so for consistency use that instead. Then commit `b42f20d2ac` "sim: testsuite: drop most specific istarget checks" caused " -sim" to be appended for all targets, which just doesn't work. For example, for crisv32-linux-gnu, that's not a recognized option and will cause a dejagnu error and further testing in c.exp will be aborted. While cris-sim.exp appends "-static" for -linux-gnu, further changes in the test-suite have caused "linux"-specific tests to break, so that part will be tended to separately. But, save and restore CFLAGS_FOR_TARGET around the modification and use where needed, to not have the CRIS-specific modification affect a continuing test-run (possibly for other targets). sim/testsuite/cris: c/c.exp (CFLAGS_FOR_TARGET): Replace appended option " -sim" with " -sim3", but do it conditionally for newlib targets. Save and restore CFLAGS_FOR_TARGET in saved_CFLAGS_FOR_TARGET such that it doesn't affect the value of CFLAGS_FOR_TARGET outside c.exp.	5 years ago
Hans-Peter Nilsson	3e6dc39ed7	sim/testsuite: Set global_cc_os also when no compiler is found If we don't set this variable, it doesn't exist, and using "#progos:" in an assembler-file will cause an error rather than just skipping the test, viz: Running /src/sim/testsuite/cris/hw/rv-n-cris/rvc.exp ... ERROR: tcl error sourcing /src/sim/testsuite/cris/hw/rv-n-cris/rvc.exp. ERROR: can't read "global_cc_os": no such variable while executing "if { $opts(progos) != "" && $opts(progos) != $global_cc_os } { untested $subdir/$name return }" (procedure "run_sim_test" line 102) Neither the commit introducing progos, nor the top comment in run_sim_test, mentions progos as intended only for C tests, or that its use must be gated on $global_cc_works != 0, so (not) setting it in the no-working-compiler path seems just overlooked. Allowing it to be used for assembler tests makes it usable for e.g. an always-false predicate and in expressions in .exp files without gating on $global_cc_works != 0. With this patch, global_cc_os is set to "", just as for "unknown OS". sim/testsuite: * lib/sim-defs.exp (sim_init_toolchain): Set global_cc_os also when no working target C compiler is found.	5 years ago
Hans-Peter Nilsson	3293b4f667	sim/testsuite/cris: Assembler testcase for PRIx32 usage bug Several C test-cases exposed the bug, but let's have one for people who test using just the assembler and linker. * asm/endmem1.ms: New test.	5 years ago
Hans-Peter Nilsson	9d67b0a097	sim cris: Correct PRIu32 to PRIx32 In `5ee0bc23a6` "sim: clean up bfd_vma printing" there was an additional introduction of PRIx32 and PRIu32 but just in sim/cris/sim-if.c. One type of bug was fixed in commit `d16ce6e4d5` "sim: cris: fix memory setup typos" but one remained; the PRIu32 usage is wrong, as hex output is desired; note the 0x prefix. Without this fix, you'll see output like: memory map 0:0x4000..0x5fff (8192 bytes) overlaps 0:0x0..0x16383 (91012 bytes) program stopped with signal 6 (Aborted). for some C programs, like some of the ones in the sim/cris/c testsuite from where the example is taken (freopen2.c). The bug behavior was with memory allocation. With an attempt to allocate memory using the brk syscall such that the room up to the next 8192-byte "page boundary" wasn't sufficient, the simulator memory allocation machinery horked on a consistency error when trying to allocate a memory block to raise the "end of the data segment": there was already memory allocated at that address. Unfortunately, none of the programs in sim/cris/asm exposed this bug at the time, but an assembler test-case is committed after this fix. sim/cris: * sim-if.c (sim_open): Correct PRIu32 to PRIx32.	5 years ago

Faraz Shahbazker	bf484e9348	sim: Allow toggling of quiet NaN-bit semantics IEEE754-1985 specifies the top bit of the mantissa as an indicator of signalling vs. quiet NaN, but does not define the precise semantics. Most architectures treat this bit as indicating quiet NaN, but legacy (pre-R6) MIPS goes the other way and treats it as signalling NaN. This used to be controlled by a macro that was only defined for MIPS. This patch replaces the macro with a variable to track the current semantics of the NaN bit and allows differentiation between older (pre-R6) and and newer MIPS cores. 2022-02-01 Faraz Shahbazker <fshahbazker@wavecomp.com> sim/common/ChangeLog: * sim-fpu.c (_sim_fpu): New.

Mike Frysinger	03b46de590	sim: ppc: drop natural types These are almost entirely unused. For the very few places using them, replace with explicit signed types. This matches what was done in the common sim code.	5 years ago
Mike Frysinger	d3eb0aa287	sim: mips: clean up bad style/whitespace This doesn't fix all the problems, but grabs a bunch of the more obvious ones.	10 years ago
Mike Frysinger	efd811591c	sim: tweak copyright lines for gnulib update-copyright The regex it uses does not like so many leading spaces which causes it to think the files lack copyright. Trim them down so the script can find & update them accordingly.	5 years ago
Joel Brobecker	4a94e36819	Automatic Copyright Year update after running gdb/copyright.py This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.	5 years ago
