2022-09-06target/i386: Make translator stop before the end of a pageIlya Leoshkevich2-1/+77
Right now translator stops right *after* the end of a page, which breaks reporting of fault locations when the last instruction of a multi-insn translation block crosses a page boundary. An implementation, like the one arm and s390x have, would require an i386 length disassembler, which is burdensome to maintain. Another alternative would be to single-step at the end of a guest page, but this may come with a performance impact. Fix by snapshotting disassembly state and restoring it after we figure out we crossed a page boundary. This includes rolling back cc_op updates and emitted ops.

2022-09-01tests/tcg: i386: add SSE testsPaul Brook1-0/+1
Tests for correct operation of most x86-64 SSE instructions. It should cover all combinations of overlapping register and memory operands on a set of random-ish data. Results are bit-identical to an Intel i5-8500, with the exception of the RCPSS and RSQRT approximations where the real CPU gives less accurate results (the Intel spec allows relative errors up to 1.5 * 2^-12) Signed-off-by: Paul Brook <paul@nowt.org> Acked-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20220424220204.2493824-42-paul@nowt.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2022-06-08Fix 'writeable' typosPeter Maydell1-1/+1
We have about 30 instances of the typo/variant spelling 'writeable', and over 500 of the more common 'writable'. Standardize on the latter. Change produced with: sed -i -e 's/\([Ww][Rr][Ii][Tt]\)[Ee]\([Aa][Bb][Ll][Ee]\)/\1\2/g' $(git grep -il writeable) and then hand-undoing the instance in linux-headers/linux/kvm.h. Most of these changes are in comments or documentation; the exceptions are: * a local variable in accel/hvf/hvf-accel-ops.c * a local variable in accel/kvm/kvm-all.c * the PMCR_WRITABLE_MASK macro in target/arm/internals.h * the EPT_VIOLATION_GPA_WRITABLE macro in target/i386/hvf/vmcs.h (which is never used anywhere) * the AR_TYPE_WRITABLE_MASK macro in target/i386/hvf/vmx.h (which is never used anywhere) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Stefan Weil <sw@weilnetz.de> Message-id: 20220505095015.2714666-1-peter.maydell@linaro.org

2022-01-18tests/tcg: use CONFIG_LINUX_USER, not CONFIG_LINUXPaolo Bonzini1-1/+1
The two more or less overlap, because CONFIG_LINUX is a requirement for Linux user-mode emulation. However, CONFIG_LINUX is technically a host symbol that applies even to system emulation. Defining CONFIG_LINUX_USER, and CONFIG_BSD_USER for eventual future use, is cleaner.

2021-10-12tests/tcg: move some multiarch files and make conditionalAlex Bennée1-0/+4
We had some messy code to filter out stuff we can't build. Lets junk that and simplify the logic by pushing some stuff into subdirs. In particular we move: float_helpers into libs - not a standalone test linux-test into linux - so we only build on Linux hosts This allows for at least some of the tests to be nominally usable by *BSD user builds.

2021-09-02tests/plugins/insn: made arg inline not positional and parse it as boolMahmoud Mandour1-1/+1
Made argument "inline" not positional, this has two benefits. First is that we adhere to how QEMU passes args generally, by taking the last value of an argument and drop the others. And the second is that this sets up a framework for potentially adding new args easily.

2021-02-18tests/plugin: expand insn test to detect duplicate instructionsAlex Bennée1-0/+10
A duplicate insn is one that is appears to be executed twice in a row. This is currently possible due to -icount and cpu_io_recompile() causing a re-translation of a block. On it's own this won't trigger any tests though. The heuristics that the plugin use can't deal with the x86 rep instruction which (validly) will look like executing the same instruction several times. To avoid problems later we tweak the rules for x86 to run the "inline" version of the plugin. This also has the advantage of increasing coverage of the plugin code (see bugfix in previous commit).

Rename Makefile.probe to Makefile.prereqs and make it actually define rules for the tests. Rename Makefile to Makefile.target, since it is not a toplevel makefile. Rename Makefile.include to Makefile.qemu and disentangle it from the QEMU Makefile.target, so that it is invoked recursively by tests/Makefile.include. Tests are now placed in tests/tcg/$(TARGET). Drop the usage of TARGET_BASE_ARCH, which is ignored by everything except x86_64 and aarch64. Fix x86 tests by using -cpu max and, while at it, standardize on QEMU_OPTS for aarch64 tests too.
