2011-04-25linux-user/arm/nwfpe: rename REG_PC to ARM_REG_PCPeter Maydell
The REG_PC constant used in the ARM nwfpe code is fine in the kernel but when used in qemu can clash with a definition in the host system include files (in particular on Ubuntu Lucid SPARC, including signal.h will define a REG_PC). Rename the constant to avoid this issue. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-04-25target-i386: switch to softfloatAurelien Jarno

2011-04-25target-i386: fix helper_fxtract() wrt softfloatAurelien Jarno
With softfloat it's not possible to play with the overflow of an unsigned value to get the 0 case partially correct. Use a special case for that. Using a division to generate an infinity is the easiest way that works for both softfloat and softfloat-native.

2011-04-25target-i386: fix helper_fscale() wrt softfloatAurelien Jarno
Use the scalbn softfloat function to implement helper_fscale(). This fixes corner cases (e.g. NaN) and makes a few more GNU libc math tests to pass. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-04-25softfloat: fix float*_scalnb() corner casesAurelien Jarno
float*_scalnb() were not taking into account all cases. This patch fixes some corner cases: - NaN values in input were not properly propagated and the invalid flag not correctly raised. Use propagateFloat*NaN() for that. - NaN or infinite values in input of floatx80_scalnb() were not correctly detected due to a typo. - The sum of exponent and n could overflow, leading to strange results. Additionally having int16 defined to int make that happening for a very small range of values. Fix that by saturating n to the maximum exponent range, and using an explicit wider type if needed.

2011-04-25softfloat: fix floatx80 handling of NaNAurelien Jarno
The floatx80 format uses an explicit bit that should be taken into account when converting to and from commonNaN format. When converting to commonNaN, the explicit bit should be removed if it is a 1, and a default NaN should be used if it is 0. When converting from commonNan, the explicit bit should be added.
