2020-09-08bpf: simulator: correct div, mod insn semanticsDavid Faust6-33/+66
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. Marchesi7-3/+79
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.

2020-09-03sim: better handle builds of primary targets lacking simsJose E. Marchesi3-6/+16
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.
2020-08-21sim/bfin: include config/pkg.m4 in configure.acSimon Marchi3-8/+302
When trying to re-generate configure in sim/bfin, I get: $ autoreconf -vf autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal --force autoreconf: configure.ac: tracing autoreconf: configure.ac: not running libtoolize: --install not given autoreconf: running: /opt/autostuff/bin/autoconf --force configure.ac:57: error: possibly undefined macro: AC_CHECK_LIB If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. autoreconf: /opt/autostuff/bin/autoconf failed with exit status: 1 This happens since commit f693213d126a ("Run `autoreconf -vf` throughout"). The problem (not clear from the error message) is that the PKG_CHECK_MODULES macro used in configure.ac is undefined. In the past, I suppose that it relied on the person running autoconf having pkg.m4 (from pkg-config) in their include path. That's not my case. Since we recently added a local version of PKG_CHECK_MODULES to our tree, we can just make sim/bfin/configure.ac use it. This patch makes configure.ac include config/pkg.m4, and re-generates configure. With this, the configure script appears to be generated correctly, I am able to configure and build the bfin simulator. Note: using sinclude to include the required m4 files makes no sense to me. These files contain macros we need, if they are not defined then the resulting file is unusable. And sinclude fails silently if the file is not found. So, better use include/m4_include. sim/bfin/ChangeLog: * configure.ac: Include config/pkg.m4. Change-Id: I7d8012e5ed510cd7746b94e918f0feb1c701cd83
2020-08-13[ARM, sim] Fix build failure with -Werror (PR26365)Luis Machado2-12/+38
There is a bit of a situation in the ARM sim with regards to the handling of argv. sim_open () gets a const char **argv, but ARM's sim_open gets clever and decides to modify argv in place via sim_target_parse_command_line. I'm not sure why. In any case, here's a fix that makes the code modify a copy of argv instead. sim/arm/ChangeLog: 2020-08-13 Luis Machado <luis.machado@linaro.org> PR sim/26365 * wrapper.c (sim_target_parse_command_line): Free discarded argv entries.

2020-08-05MSP430: sim: Fix incorrect simulation of unsigned widening multiplyJozef Lawrynowicz5-12/+90
Operand sizes used for simulation of MSP430 hardware multiply operations are not aligned with the sizes used on the target, resulting in the simulator storing signed operands with too much precision. Additionally, simulation of unsigned multiplication is missing explicit casts to prevent any implicit sign extension. gcc.c-torture/execute/pr91450-1.c uses unsigned widening multiplication of 32-bit operands -4 and 2, to produce a 64-bit result: 0xffff fffc * 0x2 = 0x1 ffff fff8 If -4 is stored in 64-bit precision, then the multiplication is essentially signed and the result is -8 in 64-bit precision (0xffff ffff ffff fffc), which is not correct. sim/msp430/ChangeLog: * msp430-sim.c (put_op): For unsigned multiplication, explicitly cast operands to the unsigned type before multiplying. * msp430-sim.h (struct msp430_cpu_state): Fix types used to store hwmult operands. sim/testsuite/sim/msp430/ChangeLog: * mpyull_hwmult.s: New test.

2019-09-19bfd_section_* macrosAlan Modra16-82/+87
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. (bfd_section_name, bfd_section_size, bfd_section_vma), (bfd_section_lma, bfd_section_alignment): Lose bfd parameter. (bfd_section_flags, bfd_section_userdata): New.

2019-09-06bfd_get_filenameAlan Modra2-1/+5
This macro says: /* Cast from const char * to char * so that caller can assign to a char * without a warning. */ I reckon that isn't such a good idea since it can result in char* variables where const char* is appropriate.

2019-04-13sim: Use host not target byte order for merging and splitting valuesAndrew Burgess2-5/+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.

I applied the patch "Do not expand macros to 'defined'" by hand because I couldn't apply it with git-am, and of course forgot to remove the macro definitions. This patch fixes it, and also makes the ChangeLog entry a bit cleaner.
2019-01-16Do not expand macros to 'defined'Pavel I. Kryukov2-5/+7
Expanding a macro which contains 'defined' PP keyword is UB. It causes a compilation failure when -Wexpansion-to-defined is used. sim/common/Changelog: 2019-01-16 Pavel I. Kryukov <kryukov@frtk.ru> * sim-arange.c: eliminate DEFINE_NON_INLINE_P
2019-01-15sim: Fix definition of SIM_ARANGE_INLINESimon Marchi2-1/+5
If HAVE_INLINE is false, SIM_ARANGE_INLINE is currently defined as #define SIM_ARANGE_INLINE EXTERN However, EXTERN is not defined anywhere, leading to errors such as: In file included from /mipt-mips/simulator/../../sim/common/sim-basics.h:147:0, from /mipt-mips/simulator/export/gdb/sim-main.h:13, from /mipt-mips/simulator/export/gdb/gdb_interface.cpp:7: /mipt-mips/simulator/../../sim/common/sim-arange.h:71:27: error: ‘EXTERN’ does not name a type; did you mean ‘EUSERS’? #define SIM_ARANGE_INLINE EXTERN ^ /mipt-mips/simulator/../../sim/common/sim-arange.h:76:1: note: in expansion of macro ‘SIM_ARANGE_INLINE’ SIM_ARANGE_INLINE int ^~~~~~~~~~~~~~~~~ I (Simon) have reproduced the problem by simply removing the HAVE_INLINE definition. This was originally reported by Pavel I. Kryukov <kryukov@frtk.ru>. sim/common/ChangeLog: * sim-arange.h (SIM_ARANGE_INLINE): Change EXTERN to extern.
2019-01-03Add 'extern C' if simulator is written in C++Павел Крюков2-0/+12
sim/common/Changelog: 2018-12-31 Pavel I. Kryukov <kryukov@frtk.ru> * sim-base.h: Add 'extern C' if header is compiled with C++
2019-01-01Update copyright year range in all GDB files.Joel Brobecker618-618/+618
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.
2018-12-18sim: Don't overwrite stored errno in sim_syscall_multiAndrew Burgess2-5/+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.
2018-12-06sim/cris: Fix references to cgen cpu directoryAndrew Burgess2-10/+13
Don't assume that cgen is located within the binutils-gdb tree. We already have CGEN_CPU_DIR and CPU_DIR defined, these are the cpu/ directory within cgen, and the cpu/ directory within binutils-cpu. The cris target tries to find CPU_DIR relative to the cgen source tree, which can be wrong when building with an out of tree cgen. sim/cris/ChangeLog: * Makefile.in: Replace uses of CGEN_CPU_DIR with CPU_DIR, and remove the definition of CGEN_CPU_DIR.
