Remove a stray #include <stdio.h> from the middle of neon_helper.c: it was harmless but pointless since we include stdio.h at the top of the file anyway. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-02-10linux-user/arm: fix compilation failures using softfloat's struct typesPeter Maydell3-19/+19

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.

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>

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>

2011-02-09linux-user: fix build errors for mmap2-only portsMike Frysinger1-1/+1
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 Frysinger1-6/+22
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 Frysinger3-17/+22
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 Frysinger1-2/+9
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 Graf3-16/+26
Different AHCI controllers have a different number of ports, so the core shouldn't care about the amount of ports available.

Sebastian's patch already did a pretty good job at splitting up ICH-9 AHCI code and the AHCI core. We need some more though. Copyright was missing, the lspci dump belongs to ICH-9, we don't need the AHCI core to have its own qdev device duplicate.
