*	sparc: Assume VIS3 support	Adhemerval Zanella	2017-11-29	1	-5/+5

*	sparc64: add a VIS3 version of ceil, floor and trunc	Aurelien Jarno	2016-08-03	1	-1/+10
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	sparc64 passes floating point values in the floating point registers. As the the generic ceil, floor and trunc functions use integer instructions, it makes sense to provide a VIS3 version consisting in the the generic version compiled with -mvis3. GCC will then use movdtox, movxtod, movwtos and movstow instructions. sparc32 passes the floating point values in the integer registers, so it doesn't make sense to do the same.

*	sparc: remove ceil, floor, trunc sparc specific implementations	Aurelien Jarno	2016-08-02	1	-11/+7
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The ceil, floor and trunc functions on sparc do not fully follow the standard and trigger an inexact exception when presented a value which is not an integer. Since glibc 2.24 this causes a few tests to fail, for instance: testing double (without inline functions) Failure: ceil (lit_pi): Exception "Inexact" set Failure: ceil (-lit_pi): Exception "Inexact" set Failure: ceil (min_subnorm_value): Exception "Inexact" set Failure: ceil (min_value): Exception "Inexact" set Failure: ceil (0.1): Exception "Inexact" set Failure: ceil (0.25): Exception "Inexact" set Failure: ceil (0.625): Exception "Inexact" set Failure: ceil (-min_subnorm_value): Exception "Inexact" set Failure: ceil (-min_value): Exception "Inexact" set Failure: ceil (-0.1): Exception "Inexact" set Failure: ceil (-0.25): Exception "Inexact" set Failure: ceil (-0.625): Exception "Inexact" set I tried to fix that by using the same strategy than used on other architectures, that is by saving the FSR register at the beginning and restoring it at the end of the function. When doing so I noticed a comment that this operation might be very costly, so I decided to do some benchmarks. The benchmarks below represent the time required to run each of the function 60 millions of times with different input value. I have done that in the basic V9 code, the VIS2 code, and using the default C implementation of the libc, for both sparc32 and sparc64, on a Niagara T1 based machine and an UltraSparc IIIi. Given I don't have access to a more recent machine), I haven't been able to test the VIS3 version. Also it should be noted that it doesn't make sense to do this benchmark for V8 or earlier as in that case we use the default C implementation. The results are available in the table below, the "+ fix" version correspond to the one saving and restoring the FSR.

On the UltraSparc IIIi the float version on sparc32 is also faster. Coming back about the fix saving and restoring the FSR, it appears it has a big impact as expected. In that case the C implementation is always faster than the fixed implementations. This patch therefore removes the sparc specific implementations in favor of the generic ones.
