* powerpc: Remove optimized isnanAdhemerval Zanella2019-06-122-106/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc isnan optimizations are not really a gain: - GCC will call libm iff -fsignaling-nans is used. This usage pattern is usually not performance oriented and for such calls PLT overhead should dominate execution time. - The power5, power6, and power6x are just micro-optimization to improve the Load-Hit-Store hazards from floating-point to general register transfer, and current GCC already has support to minimize it by inserting either extra nops or group dispatch instructions. - The power7 uses ftdiv to optimize for some input patterns, but at cost of others. Comparing against generic C implementation built for powerpc-linux-gnu-power4 (which uses the hp-timing support on benchtests): - Generic sysdeps/ieee754 implementation: "isnan": { "": { "duration": 4.98415e+09, "iterations": 2.34516e+09, "max": 45.925, "min": 2.052, "mean": 2.12529 }, "INF": { "duration": 4.74057e+09, "iterations": 1.69761e+09, "max": 91.01, "min": 2.052, "mean": 2.79249 }, "NAN": { "duration": 4.74071e+09, "iterations": 1.68768e+09, "max": 282.343, "min": 2.052, "mean": 2.809 } } - power7 optimized one: $ ./testrun.sh benchtests/bench-isnan "isnan": { "": { "duration": 4.96842e+09, "iterations": 2.56297e+09, "max": 50.048, "min": 1.872, "mean": 1.93854 }, "INF": { "duration": 4.76648e+09, "iterations": 1.54213e+09, "max": 373.408, "min": 2.661, "mean": 3.09084 }, "NAN": { "duration": 4.76845e+09, "iterations": 1.54515e+09, "max": 51.016, "min": 2.736, "mean": 3.08607 } } So it basically optimizes marginally for normal numbers while increasing the latency for other kind of FP. - The generic implementation requires getting the floating point status, disable the invalid operation bit, and restore the floating-point status. Each operation is costly and requires flushing the FP pipeline. Using the same scenarion for the previous analysis: "isnan": { "": { "duration": 5.08284e+09, "iterations": 6.2898e+08, "max": 41.844, "min": 8.057, "mean": 8.08108 }, "INF": { "duration": 4.97904e+09, "iterations": 6.16176e+08, "max": 39.661, "min": 8.057, "mean": 8.08055 }, "NAN": { "duration": 4.98695e+09, "iterations": 5.95866e+08, "max": 29.728, "min": 8.345, "mean": 8.36925 } } - The power8 implementation is just the generic implementation using ISA 2.07 mfvsrd instruction (which GCC uses for generic implementation). So generic implementation is the best option for powerpc64le.

* Remove powerpc32 sqrt wrappers.Joseph Myers2017-08-252-206/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the powerpc32-specific wrappers for sqrt and sqrtf. These wrappers, by adding architecture-specific uses of _LIB_VERSION and __kernel_standard, unnecessarily complicate cleanups of libm error handling. They also do not serve a useful optimization purpose. GCC knows about sqrt as a built-in function, and can generate direct calls to a hardware square root instruction, either on its own, in the -fno-math-errno case, or together with an inline check for the argument being negative and a call to the out-of-line sqrt function for error handling only in that case (and has been able to do so for a long time). Thus in practice the wrapper will only be called only in the case of negative arguments, which is not a case it is useful to optimize for. Tested with build-many-glibcs.py for powerpc-linux-gnu-power4. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/w_sqrt_compat-power5.S: Remove file. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/w_sqrt_compat-ppc32.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/w_sqrt_compat.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/w_sqrtf_compat-power5.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/w_sqrtf_compat-ppc32.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/w_sqrtf_compat.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/w_sqrt_compat.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/w_sqrtf_compat.S: Likewise. * sysdeps/powerpc/powerpc32/power5/fpu/w_sqrt_compat.S: Likewise. * sysdeps/powerpc/powerpc32/power5/fpu/w_sqrtf_compat.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/Makefile (libm-sysdep-routines): Remove w_sqrt_compat-power5, w_sqrt_compat-ppc32, w_sqrtf_compat-power5 and w_sqrtf_compat-ppc32.
* Obsolete matherr, _LIB_VERSION, libieee.a.Joseph Myers2017-08-212-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch obsoletes support for SVID libm error handling (the system where a user-defined function matherr is called on a libm function error; only enabled if you also set _LIB_VERSION = _SVID_ or _LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global variable to control libm error handling. matherr and _LIB_VERSION are made into compat symbols, not supported for new ports or for static linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_, so disabling errno setting for some functions) is also removed, and all the related definitions are removed from math.h. The manual already recommends against using matherr, and it's already not supported for _Float128 functions (those use new wrappers that don't support matherr, only errno) - this patch means that it becomes possible to e.g. add sinf32 as an alias to sinf without that resulting in undesired matherr support in sinf32 for existing glibc ports. matherr support is not part of any standard supported by glibc (it was removed in XPG4). Because matherr is a function to be defined by the user, of course user programs defining such a function will still continue to link; it just quietly won't be used. If they try to write to the library's copy of _LIB_VERSION to enable SVID error handling, however, they will get a link error (but if they define their own _LIB_VERSION variable, they won't). I expect the most likely case of build failures from this patch to be programs with unconditional cargo-culted uses of -lieee (based on a notion of "I want IEEE floating point", not any actual requirement for that library). Ideally, the new-port-or-static-linking case would use the new wrappers used for _Float128. This is not implemented in this patch, because of the complication of architecture-specific (powerpc32 and sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard directly. Thus, the old wrappers and __kernel_standard are still built unconditionally, and _LIB_VERSION still exists in static libm. But when the old wrappers and __kernel_standard are built in the non-compat case, _LIB_VERSION and matherr are defined as macros so code to support those features isn't actually built into static libm or new ports' shared libm after this patch. I intend to move to the new wrappers for static libm and new ports in followup patches. I believe the sqrt wrappers for powerpc32 and sparc can reasonably be removed. GCC already optimizes the normal case of sqrt by generating code that uses a hardware instruction and only calls the sqrt function if the argument was negative (if -fno-math-errno, of course, it just uses the hardware instruction without any check for negative argument being needed). Thus those wrappers will only actually get called in the case of negative arguments, which is not a case it makes sense to optimize for. But even without removing the powerpc32 and sparc wrappers it should still be possible to move to the new wrappers for static libm and new ports, just without having those dubious architecture-specific optimizations in static libm. Everything said about matherr equally applies to matherrf and matherrl (IA64-specific, undocumented), except that the structure of IA64 libm means it won't be converted to using the new wrappers (it doesn't use the old ones either, but its own error-handling code instead). As with other tests of compat symbols, I expect test-matherr and test-matherr-2 to need to become appropriately conditional once we have a system for disabling such tests for ports too new to have the relevant symbols.

| | | | | | | | | | This commit moves one step towards the deprecation of wrappers that use _LIB_VERSION / matherr / __kernel_standard functionality, by adding the suffix '_compat' to their filenames and adjusting Makefiles and #includes accordingly. New template wrappers that do not use such functionality will be added by future patches and will be first used by the float128 wrappers.

* powerpc: Re-work the Implies structureLuis Machado2010-06-302-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tries to organize the implies files for ppc, since there are a number of processors and most of them are compatible with each other (backwards compatible). Having in mind that we start the search for processor-specific files in the sysdeps/unix/sysv/linux tree (sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/[processor]/fpu to be exact), we would like to grab any linux-specific code from that tree prior to going through the other tree (sysdeps/powerpc/...). For that, i removed the Implies files that were originally inside the fpu directories and placed then in the non-fpu directories (still inside the unix/sysv/linux tree). If no processor-specific/linux-specific files could be found, we "imply" the other tree's (sysdeps/powerpc/...) fpu directory for that specific processor AND also the non-fpu directory for that same tree. If, again, no processor-specific code is found, we read another Implies file that will point to the most compatible processor that we should grab code from, and so on, until we reach the power4 processor. So, in summary, the Implies files will live inside these directories now: * sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/[processor] * sysdeps/powerpc/powerpc[32|64]/[processor] Practical example of the order we will use to pick power6-specific code with the new structure. sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/power6/fpu -> sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/power6 -> sysdeps/powerpc/powerpc[32|64]/power6/fpu -> sysdeps/powerpc/powerpc[32|64]/power6 -> sysdeps/powerpc/powerpc[32|64]/power5+/fpu -> sysdeps/powerpc/powerpc[32|64]/power5+ -> sysdeps/powerpc/powerpc[32|64]/power5/fpu -> sysdeps/powerpc/powerpc[32|64]/power5 -> sysdeps/powerpc/powerpc[32|64]/power4/fpu -> sysdeps/powerpc/powerpc[32|64]/power4 (from here, it'll go to the generic path as usual)
