2023-11-02tests/tcg: Add -fno-stack-protectorAkihiko Odaki
A build of GCC 13.2 will have stack protector enabled by default if it was configured with --enable-default-ssp option. For such a compiler, it is necessary to explicitly disable stack protector when linking without standard libraries.

2022-10-06tests/tcg: clean up calls to run-testPaolo Bonzini
Almost all invocations of run-test have either "$* on $(TARGET_NAME)" or "$< on $(TARGET_NAME)" as the last argument. So provide a default test name, while allowing an escape hatch for custom names.

2022-07-06tests/tcg: compile system emulation tests as freestandingPaolo Bonzini
System emulation tests do not run in a hosted environment, since they do not link with libc. They should only use freestanding headers (float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h, stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding in order to use the compiler implementation of those headers rather than the one in libc. Some tests are using inttypes.h instead of stdint.h, so fix that. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2022-03-18target/arm: Fix sve2 ldnt1 and stnt1Richard Henderson
For both ldnt1 and stnt1, the meaning of the Rn and Rm are different from ld1 and st1: the vector and integer registers are reversed, and the integer register 31 refers to XZR instead of SP. Secondly, the 64-bit version of ldnt1 was being interpreted as 32-bit unpacked unscaled offset instead of 64-bit unscaled offset, which discarded the upper 32 bits of the address coming from the vector argument. Thirdly, validate that the memory element size is in range for the vector element size for ldnt1. For ld1, we do this via independent decode patterns, but for ldnt1 we need to do it manually.

The aim of this is to test code generation for vectorised operations. Unfortunately gcc struggles to do much with the messy sha1 code (try -fopt-info-vec-missed to see why).

2020-08-03target/arm: Fix AddPAC error indicationRichard Henderson
The definition of top_bit used in this function is one higher than that used in the Arm ARM psuedo-code, which put the error indication at top_bit - 1 at the wrong place, which meant that it wasn't visible to Auth. Fixing the definition of top_bit requires more changes, because its most common use is for the count of bits in top_bit:bot_bit, which would then need to be computed as top_bit - bot_bit + 1.

2019-09-26tests/tcg: add simple record/replay smoke test for aarch64Alex Bennée
This adds two new tests that re-use the memory test to check basic record replay functionality is still working. We have to define our own runners rather than using the default pattern as we want to change the test name but re-use the memory binary. We declare the test binaries as PHONY as they don't really exist. [AJB: A better test would output some sort of timer value or other otherwise variable value so we could compare the record and replay outputs and ensure they match] Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Cc: Pavel Dovgalyuk <dovgaluk@ispras.ru>
2019-09-26tests/tcg: add generic version of float_convsAlex Bennée
This is broadly similar to the existing fcvt test for ARM but using the generic float testing framework. We should be able to pare down the ARM fcvt test case to purely half-precision with or without the Alt HP provision.

2019-09-26tests/tcg: add float_madds test to multiarchAlex Bennée
This is a generic floating point multiply and accumulate test for single precision floating point values. I've split of the common float functions into a helper library so additional tests can use the same common code. As I don't have references for all architectures I've allowed some flexibility for tests to pass without reference files. They can be added as we get collect them.

2019-09-26tests/tcg: clean-up some comments after the de-tanglingAlex Bennée
These were missed in the recent de-tangling so have been updated to be more actuate. I've also built up ARM_TESTS in a manner similar to AARCH64_TESTS for better consistency.
