* Fix errno handling in posix_openpt.Andreas Schwab2009-10-291-2/+5
| | | | | | The implementation of posix_openpt on Linux can fail in a few extra ways if the appropriate pseudo filesystems are not mounted etc. In some of these cases we have to explicitly set errno.
* Fix getttyname on Linux when called for different devices.Ulrich Drepper2009-10-291-1/+6
| | | | | | If a second call to ttyname is not for the same type of device (e.g., serial vs ptty) the prefix of the buffer was wrong. Don't rely on the previous content, always reinitialize it.
* Add macros for DSCP markings.Philip Prindeville2009-10-291-1/+37

* Fix F_GETOWN on some Linux archs.Ulrich Drepper2009-10-293-5/+71
| | | | | | The syscall conventions on some Linux archs prevented F_GETOWN from working correctly in some situations. This can be rectified when using the new F_GETOWN_EX command.

* Add ____longjmp_chk for sparcDavid S. Miller2009-10-142-0/+184
| | | | | | | | | | | tst-longjmp_chk passes, tst-longjmp_chk2 fails but that is because of some limitations of kernel signal delivery on sparc that I need to fix, it has nothing to do with the longjmp_chk implementation. (The problem with tst-longjmp_chk2 is that it tries to do a stack fault SIGSEGV within a stack fault SIGSEGV , and the Linux kernel will refuse to setup the signal stack and deliver the signal if the register windows can't be written out to the stack first)

| | | | | It turns that SSSE3 isn't slow on Atom. The problem is bsf. This patch removes ENABLE_SSSE3_ON_ATOM.

* Handle AVX saving on x86-64 in interrupted smbol lookups.Ulrich Drepper2009-08-251-1/+0
| | | | | | | | | If a signal arrived during a symbol lookup and the signal handler also required a symbol lookup, the end of the lookup in the signal handler reset the flag whether restoring AVX/SSE registers is needed. Resetting means in this case that the tail part of the outer lookup code will try to restore the registers and this can fail miserably. We now restore to the previous value which makes nesting calls possible.
* Add ceil implementation for 64-bit machines.Ulrich Drepper2009-08-242-0/+84
| | | | | | | On 64-bit machines we should not split doubles into two 32 bit integer and handle the words separately. We have wide registers. This patch implements a 64-bit ceil version. Ideally all other functions will be converted over time.

* Support mixed SSE/AVX audit and check AVX only once.H.J. Lu2009-08-082-237/+276
| | | | | | | | | | This patch fixes mixed SSE/AVX audit and checks AVX only once in _dl_runtime_profile. When an AVX or SSE register value in pltenter is modified, we have to make sure that the SSE part value is the same in both lr_xmm and lr_vector fields so that pltexit will get the correct value from either lr_xmm or lr_vector fields. AVX-enabled pltenter should update both lr_xmm and lr_vector fields to support stacked AVX/SSE pltenter functions.
