2015-03-27ARC/signal: shield sa_restorer from compiler toggle side-effectsVineet Gupta
when building uClibc with -O0 (DODEBUG build) the default sigrestorer had some extra glue code generated for stack manipulation which was messing up resume from signal path. So annotate the function with -Os so that gcc would only generate the bare min 2 instruction TRAP sequence Reported-and-Debugged-by: Alexey Brodkin <abrodkin@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> 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.

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.

This is not true for ARCv2 ISA and possibly other arch of future with 64-bit even register requirement, which uses the standard syscall handler in kernel.
