2011-06-03softfloat-native: removeAurelien Jarno1-531/+0
Remove softfloat-native support, all targets are now using softfloat instead. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-04-25softfloat-native: add float*_is_any_nan() functionsAurelien Jarno1-0/+3
Add float*_is_any_nan() functions to match the softfloat API. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-04-25softfloat-native: fix float*_scalbn() functionsAurelien Jarno1-3/+3
float*_scalbn() should be able to take a status parameter. Fix that. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-04-17softfloat: rename float*_eq_signaling() into float*_eq()Aurelien Jarno1-3/+3
float*_eq_signaling functions have a different semantics than other comparison functions. Fix that by renaming float*_quiet_signaling() into float*_eq(). Note that it is purely mechanical, and the behaviour should be unchanged. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-04-17softfloat: rename float*_eq() into float*_eq_quiet()Aurelien Jarno1-3/+3
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.

2011-04-17softfloat-native: add float*_unordered_quiet() functionsAurelien Jarno1-3/+12
Add float*_unordered_quiet() functions to march the softfloat versions. As FPU status is not tracked with softfloat-native, they don't differ from the signaling version. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-02softfloat: Rename float*_is_nan() functions to float*_is_quiet_nan()Peter Maydell1-3/+3
The softfloat functions float*_is_nan() were badly misnamed, because they return true only for quiet NaNs, not for all NaNs. Rename them to float*_is_quiet_nan() to more accurately reflect what they do. This change was produced by: perl -p -i -e 's/_is_nan/_is_quiet_nan/g' $(git grep -l is_nan) (with the results manually checked.)

2010-02-06arm host: fix compiler warningStefan Weil1-7/+0
Compilation for arm (native or cross) results in this warning: fpu/softfloat-native.c: In function ‘float64_round_to_int’: fpu/softfloat-native.c:387: error: control reaches end of non-void function float64_round_to_int uses special assembler code for arm and has no explicit return value. As there is no obvious reason why arm should need special code, all fpu related conditionals were removed. The remaining code is standard (C99) and compiles for arm, too.

Don't define C99 math functions on OpenSolaris (Solaris 11), which still ships GCC 3.4.3. This fixes redefinition warnings. Spotted by Palle Lyckegaard.
