* target-i386: fix dpps and dppd SSE2 instructionsAurelien Jarno2012-01-111-14/+14
| | | | | | | | The helpers implemented dpps and dppd SSE instructions are not passing the correct argument types to the softfloat functions. While they do work anyway providing a correct behaviour, this patch fixes that. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
* target-i386: fix round{pd,ps,sd,ss} SSE2 instructionsAurelien Jarno2012-01-111-8/+8
| | | | | | | | | | | | | roundps and roundss SSE2 instructions have been broken when switching target-i386 to softfloat. They use float64_round_to_int to convert a float32, and while the implicit conversion from float32 to float64 was correct for softfloat-native, it is not for pure softfloat. Fix that by using the correct registers and correct functions. Also fix roundpd and roundsd implementation at the same time, even if these functions are behaving correctly.

* target-i386: fix {min,max}{pd,ps,sd,ss} SSE2 instructionsAurelien Jarno2012-01-111-2/+7
| | | | | | | | | | | | | | | | | | | minpd, minps, minsd, minss and maxpd, maxps, maxsd, maxss SSE2 instructions have been broken when switching target-i386 to softfloat. It's not possible to use comparison instructions on float types anymore to softfloat, so use the floatXX_lt function instead, as the float_XX_min and float_XX_max functions can't be used due to the Intel specific behaviour. As it implements the correct NaNs behaviour, let's remove the corresponding entry from the TODO. It fixes GDM screen display on Debian Lenny. Thanks to Peter Maydell and Jason Wessel for their analysis of the problem. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
* x86: fix pcmpestrm and pcmpistrmBlue Swirl2011-11-191-4/+8
| | | | | | | | | Fix obvious typos (decrement and off-by-one error) in pcmpestrm and pcmpistrm which resulted in infinite loop. Reported by Frank Mehnert, spotted also by Coverity (bug 84752853). Reported-by: Frank Mehnert <frank.mehnert@oracle.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* target-i386: Fix several SSE3 instructions.Max Reitz2011-09-171-18/+18
| | | | | | | | | | haddp[sd], hsubp[sd] and addsubp[sd] operate on floats, thus it is necessary to use the appropriate floating point calculation functions. If this is not done, those functions operate merely on integers, which is not correct. Signed-off-by: Max Reitz <max@tyndur.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

* softfloat: rename float*_eq() into float*_eq_quiet()Aurelien Jarno2011-04-171-4/+4
| | | | | | | | | | | | | | float*_eq functions have a different semantics than other comparison functions. Fix that by first renaming float*_quiet() into float*_eq_quiet(). Note that it is purely mechanical, and the behaviour should be unchanged. That said it clearly highlight problems due to this different semantics, they are fixed later in this patch series.

* target-i386: add SSE4a instruction supportAndre Przywara2009-10-041-0/+44
| | | | | | | | | | | | | | This adds support for the AMD Phenom/Barcelona's SSE4a instructions. Those include insertq and extrq, which are doing shift and mask on XMM registers, in two versions (immediate shift/length values and stored in another XMM register). Additionally it implements movntss, movntsd, which are scalar non-temporal stores (avoiding cache trashing). These are implemented as normal stores, though. SSE4a is guarded by the SSE4A CPUID bit (Fn8000_0001:ECX[6]). Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
