2015-01-29softfloat: Clarify license statusPeter Maydell
The code in the softfloat source files is under a mixture of licenses: the original code and many changes from QEMU contributors are under the base SoftFloat-2a license; changes from Stefan Weil and RedHat employees are GPLv2-or-later; changes from Fabrice Bellard are under the BSD license. Clarify this in the comments at the top of each affected source file, including a statement about the assumed licensing for future contributions, so we don't need to remember to ask patch submitters explicitly to pick a license.

2015-01-29softfloat: Revert and reimplement remaining parts of b645bb4885 and 5a6932d51dPeter Maydell
Revert the parts of commits b645bb4885 and 5a6932d51d which are still in the codebase and under a SoftFloat-2b license. Reimplement support for architectures where the most significant bit in the mantissa is 1 for a signaling NaN rather than a quiet NaN, by adding handling for SNAN_BIT_IS_ONE being set to the functions which test values for NaN-ness. This includes restoring the bugfixes lost in the reversion where some of the float*_is_quiet_nan() functions were returning true for both signaling and quiet NaNs.

2015-01-27linux-user: Fix broken m68k signal handling on 64 bit hostsPeter Maydell
The m68k signal frame setup code which writes the signal return trampoline code to the stack was assuming that a 'long' was 32 bits; on 64 bit systems this meant we would end up writing the 32 bit (2 insn) trampoline sequence to retaddr+4,retaddr+6 instead of the intended retaddr+0,retaddr+2, resulting in a guest crash when it tried to execute the invalid zero-bytes at retaddr+0. Fix by using uint32_t instead; also use uint16_t rather than short for consistency. This fixes bug LP:1404690.

2015-01-27linux-user: Fix ioctl cmd type mismatch on 64-bit targetsEd Swierk
linux-user passes the cmd argument of the ioctl syscall as a signed long, but compares it to an unsigned int when iterating through the ioctl_entries list. When the cmd is a large value like 0x80047476 (TARGET_TIOCSWINSZ on mips64) it gets sign-extended to 0xffffffff80047476, causing the comparison to fail and resulting in lots of spurious "Unsupported ioctl" errors. Changing the target_cmd field in the ioctl_entries list to a signed int causes those values to be sign-extended as well during the comparison.

2015-01-27linux-user/signal.c: Remove unnecessary wrapper copy_siginfo_to_userPeter Maydell
The function copy_siginfo_to_user() just calls tswap_siginfo(), so call the latter function directly and delete the wrapper function. The wrapper is actually misleading since it implies that the semantics are like the kernel function with the same name which copies the data to a guest user-space address. In fact tswap_siginfo() just does data-structure conversion between two structures whose addresses are host addresses (the copy to userspace is handled in QEMU by the lock_user/unlock_user calls). This also fixes clang complaints about the wrapper being unused in some configs. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2015-01-27linux-user/alpha: Add define for NR_shmat to enable shmat syscallPeter Maydell
For historical reasons, the define for the shmat() syscall on Alpha is NR_osf_shmat; however it has the same semantics as this syscall does on all other architectures, so define TARGET_NR_shmat as well so that QEMU's code for the syscall is enabled. This patch brings our behaviour on the LTP shmat tests into line with that for ARM (still not a perfect pass rate but not "this syscall is completely broken" as we had before). (Problem detected via a clang warning that the do_shmat() function was unused on Alpha.)

2015-01-27linux-user/signal.c: Remove current_exec_domain_sig()Peter Maydell
Remove the function current_exec_domain_sig(), which always returns its argument. This was intended as a stub for supporting the kernel's exec_domain handling, but: * we don't have any of the other code for execution domains * in the kernel this handling is architecture-specific, not generic * we only call this function in the x86, ppc and sh4 signal code paths, and the PPC one is wrong anyway because the PPC kernel doesn't have this signal-remapping code So it's best to simply delete the function; any future attempt to implement exec domains will be better served by adding the correct code from scratch based on the kernel sources at that time. This change also fixes some clang warnings about the function being defined but not used for some target architectures.

2015-01-26target-tricore: split up suov32 into suov32_pos and suov32_negBastian Koppelmann
suov checks unsigned for an overflow and an underflow, after some arithmetic operations and saturates the result to either max_uint32 or 0. So far we handled this by expanding to the next bigger data type and compare whether the result is > max_uint32 or < 0. However this approach can fail for an 32 bit multiplication, if both operands of the multiplication are 0x80000000. This sets the sign bit of the 64 bit integer and would result in a false saturation to 0. Since unsigned operations, e.g add, sub, mul always result in either a positive or negative overflow, we split the functions for suov32 up into two functions (suov32_pos, suov32_neg) for each case.
