* linux-user: Merge pread/pwrite into pread64/pwrite64Peter Maydell2012-12-081-2/+2
| | | | | | | | | | | | | | | | The Linux syscalls underlying pread() and pwrite() take a 64 bit offset on all architectures, even if some of them name the syscall "pread/pwrite" rather than "pread64/pwrite64" for historical reasons. So move the four QEMU target architectures (arm, i386, sparc, unicore32) which were defining TARGET_NR_pread/pwrite to define TARGET_NR_pread64/pwrite64 instead, and drop the TARGET_NR_pread/pwrite implementation code completely. (Based on examination of the kernel sources for the four architectures this patch affects.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

* linux-user/arm/syscall_nr.h: Add syscall number for ppollPeter Maydell2012-04-061-1/+1
| | | | | | | | | | | The list of ARM syscall numbers was missing the entry for ppoll, which meant we were accidentally not providing it. (This wasn't causing any practical issues beyond warnings about unimplemented syscalls, because glibc will fall back to another code path if the syscall isn't present.)

* linux-user/arm/nwfpe: rename REG_PC to ARM_REG_PCPeter Maydell2011-04-253-6/+6
| | | | | | | | | | 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>
* softfloat: rename float*_eq() into float*_eq_quiet()Aurelien Jarno2011-04-171-1/+1
| | | | | | | | | | | | | | 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.

* linux-user: Fix incorrect NaN detection in ARM nwfpe emulationPeter Maydell2011-01-071-7/+7
| | | | | | | | | | | | | | | | | The code in the linux-user ARM nwfpe emulation was incorrectly checking only for quiet NaNs when it should have been checking for any kind of NaN. This is probably because the code in question was taken from the Linux kernel, whose copy of the softfloat library had been modified so that float*_is_nan() returned true for all NaNs, not just quiet ones. The qemu equivalent function is float*_is_any_nan(), so use that. NB that this code is really obsolete since nobody uses FPE for actual arithmetic now; this is just cleanup following the recent renaming of the NaN related functions.

* softfloat: Rename float*_is_nan() functions to float*_is_quiet_nan()Peter Maydell2011-01-021-7/+7
| | | | | | | | | | | | | | | | 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.)
