Lynne	1978b143eb	checkasm: add av_tx FFT SIMD testing code This sadly required making changes to the code itself, due to the same context needing to be reused for both versions. The lookup table had to be duplicated for both versions.	4 years ago

Martin Storsjö	ed7d73355e	checkasm: aarch64: Check for stack overflows Also fill x8-x17 with garbage before calling the function. Figure out the number of stack parameters and make sure that the value on the stack after those is untouched. Signed-off-by: Martin Storsjö <martin@martin.st>	5 years ago

Clément Bœsch	e0d56f097f	checkasm: use perf API on Linux ARM* On ARM platforms, accessing the PMU registers requires special user access permissions. Since there is no other way to get accurate timers, the current implementation of timers in FFmpeg rely on these registers. Unfortunately, enabling user access to these registers on Linux is not trivial, and generally involve compiling a random and unreliable github kernel module, or patching somehow your kernel. Such module is very unlikely to reach the upstream anytime soon. Quoting Robin Murphin from ARM: > Say you do give userspace direct access to the PMU; now run two or more > programs at once that believe they can use the counters for their own > "minimal-overhead" profiling. Have fun interpreting those results... > > And that's not even getting into the implications of scheduling across > different CPUs, CPUidle, etc. where the PMU state is completely beyond > userspace's control. In general, the plan to provide userspace with > something which might happen to just about work in a few corner cases, > but is meaningless, misleading or downright broken in all others, is to > never do so. As a result, the alternative is to use the Performance Monitoring Linux API which makes use of these registers internally (assuming the PMU of your ARM board is supported in the kernel, which is definitely not a given...). While the Linux API is obviously cross platform, it does have a significant overhead which needs to be taken into account. As a result, that mode is only weakly enabled on ARM platforms exclusively. Note on the non flexibility of the implementation: the timers (native FFmpeg vs Linux API) are selected at compilation time to prevent the need of function calls, which would result in a negative impact on the cycle counters.	7 years ago

James Almer	37388b119c	checkasm: add a checkasm_checked_call function that doesn't issue emms Meant for DSP functions returning a float or double, as they'd fail if emms is called after every run on x86_32. Signed-off-by: James Almer <jamrial@gmail.com>	8 years ago

Martin Storsjö	c91d6a33f8	checkasm: aarch64: Add filler args to make sure all parameters are passed on the stack This, combined with clobbering the stack space prior to the call, increases the chances of finding cases where 32 bit parameters are erroneously treated as 64 bit.

Martin Storsjö	dc7501e524	checkasm: Issue emms after benchmarking functions The functions may not clean up properly after using MMX registers. For the normal testing calls, the checkasm_checked_call functions will do the cleanup (and check that functions that should clean up do it as well), but when benchmarking functions that don't clean up, we don't currently properly clean up at all. This causes issues if a benchmarked function is followed by testing of a function that is supposed to not clobber the MMX/FPU state but doesn't touch it at all.

Martin Storsjö	fec76cd430	checkasm: Check register clobbering on aarch64 This is disabled on iOS, since iOS uses a slightly different ABI for vararg parameters. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Martin Storsjö	26ec75aec3	checkasm: Check register clobbering on arm Use two separate functions, depending on whether VFP/NEON is available. This is set to require armv5te - it uses blx, which is only available since armv5t, but we don't have a separate configure item for that. (It also uses ldrd, which requires armv5te, but this could be avoided if necessary.) Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
