2015-03-26ldso: mark _dl_exit as noreturnBernhard Reutner-Fischer
Otherwise gcc might not understand that oom() ended control-flow and might emit an (untaken) reference to abort() in _dl_update_slotinfo() on e.g. SH4 which breaks linking ld-uClibc.so. Arguably -ffreestanding should prevent GCC from emitting this '.global abort' but alas, it does not, which is another bug.. Also mark the function cold to further lower the incoming frequency and branch probability. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2015-03-25utmp: favour POSIX utmpx over SVID utmpBernhard Reutner-Fischer
Note: _PATH_UTMPX == _PATH_UTMP and the utmp struct is identical to the utmpx struct so this only changes the external API entrypoints and NOT the underlying data source. This saves about 500b (~1300b from previously ~1950) while at it. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

nostdlib disables linking in startup files too which is not what we want here since it needs to resolve __dso_handle which comes from crtbeginS.o, otherwise librt has this undefined reference to a weak undefined __dso_handle that shows up as error (with gold linker) when shared libraries are being built which are linking in librt Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

For some rarely cases(almost App bugs), calling malloc with a very largre size, checked_request2size check will fail,set ENOMEM, and return 0 to caller. But this will let __malloc_lock futex locked and owned by the caller. In multithread circumstance, other thread calling malloc/calloc will NOT succeed and get locked.

2015-03-16resolv: fix unaligned tmp buffer corner-caseAlexey Brodkin
On execution of "inet/gethost_r-align" test I noticed failure due to unaligned access (instaed of 4-byte aligned 1-byte aligned address was attempted to be accessed). Further investigation confirmed this nice and helpful test failure. Following commit removed usage of ALIGN_BUFFER_OFFSET on entry to __read_etc_hosts_r(): http://git.uclibc.org/uClibc/commit/?id=f65e66078b9f4d2d7f0fc336dee36e78fc467c0f So indeed if target architecture doesn't allow unaligned access and provided tmp buffer is not word aligned (and we will deal with pointers which means word-sized data units), then CPU will fail during execution. In case of ARC we'll see "Unaligned access" exception like this: --->8--- # potentially unexpected fatal signal 7.
