2011-02-10softfloat: Fix compilation failures with USE_SOFTFLOAT_STRUCT_TYPESPeter Maydell
Make softfloat compile with USE_SOFTFLOAT_STRUCT_TYPES defined, by adding and using new macros const_float16(), const_float32() and const_float64() so you can use array initializers in an array of float16/float32/float64 whether the types are bare or wrapped in the structs. [aurelien@aurel32.net: do the same for float16] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-02-10target-arm: Use standard FPSCR for Neon half-precision operationsPeter Maydell
The Neon half-precision conversion operations (VCVT.F16.F32 and VCVT.F32.F16) use ARM standard floating-point arithmetic, unlike the VFP versions (VCVTB and VCVTT). Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-02-10softfloat: Correctly handle NaNs in float16_to_float32()Peter Maydell
Correctly handle NaNs in float16_to_float32(), by defining and using a float16ToCommonNaN() function, as we do with the other formats. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-02-10softfloat: Fix single-to-half precision float conversionsPeter Maydell
Fix various bugs in the single-to-half-precision conversion code: * input NaNs not correctly converted in IEEE mode (fixed by defining and using a commonNaNToFloat16()) * wrong values returned when converting NaN/Inf into non-IEEE half precision value * wrong values returned for conversion of values which are on the boundary between denormal and zero for the half precision format * zeroes not correctly identified * excessively large results in non-IEEE mode should generate InvalidOp, not Overflow Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-02-10softfloat: Honour default_nan_mode for float-to-float conversionsChristophe Lyon
Honour the default_nan_mode flag when doing conversions between different floating point formats, as well as when returning a NaN from a two-operand floating point function. This corrects the behaviour of float<->double conversions on both ARM and SH4.

2011-02-10softfloat: Add float16 type and float16 NaN handling functionsPeter Maydell
Add a float16 type to softfloat, rather than using bits16 directly. Also add the missing functions float16_is_quiet_nan(), float16_is_signaling_nan() and float16_maybe_silence_nan(), which are needed for the float16 conversion routines.

2011-02-09linux-user: fix for loopmount ioctlMartin Mohring
In case a chrooted build uses XEN or KVM, a looped mount needs to be done to setup the chroot. The ioctl for loop mount works correctly for arm, mips, ppc32 and sh4, so its now activated. Signed-off-by: Riku Voipio <riku.voipio@nokia.com>
2011-02-09linux-user: fix build errors for mmap2-only portsMike Frysinger
The current print_mmap func is only enabled when the target supports the mmap syscall, but both mmap and mmap2 syscalls use it. This leads to a build failure when the target supports mmap2 but not mmap. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Riku Voipio <riku.voipio@nokia.com>
2011-02-09user: speed up init_paths a bitMike Frysinger
The current init_paths code will attempt to opendir() every single file it finds. This can obviously generated a huge number of syscalls with even a moderately small sysroot that will fail. Since the readdir() call provides the file type in the struct itself, use it. On my system, this prevents over 1000 syscalls from being made at every invocation of a target binary, and I only have a C library installed.

2011-02-09linux-user/FLAT: allow targets to override FLAT processingMike Frysinger
This brings flatload.c more in line with the current Linux FLAT loader which allows targets to handle various FLAT aspects in their own way.

2011-02-09linux-user/FLAT: fix auto-stack sizingMike Frysinger
The current auto-stack sizing works like it does on a NOMMU system; the problem is that this only works if the envp/argv arrays are fairly slim. On a desktop system, this is rarely the case, and can easily blow past the stack and into data/text regions as the default stack for FLAT progs is a mere 4KiB. So rather than rely on the NOMMU calculation (which is only there because NOMMU can't easily allocate gobs of contiguous mem), calc the full space actually needed and let the MMU host make space.

2011-02-07ahci: make number of ports runtime determinedAlexander Graf
