2009-11-22remove wait callbacks for non-cancelation funcsBernhard Reutner-Fischer
No need to install a cancellation handler, these are no cancellation point. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-22include string.h for memset()Bernhard Reutner-Fischer
This avoids a warnings about implicit declaration of function 'memset'. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2009-11-09disable _POSIX_SPAWN defineMike Frysinger
We don't provide spawn.h let alone any other spawn funcs/types, so don't set up the _POSIX_SPAWN define that some packages (like vlc) check. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09build with -fmerge-all-constantsMike Frysinger
Glibc is already using this flag and it gives us a slight code shrink in a few functions. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09test/plt: add a script to find PLT usageMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09libc: add hidden calls to pthread cleanup funcsMike Frysinger
A lot of libc code calls the pthread cleanup funcs implicitly (for stdio) which currently goes through the PLT. Since we already have forwarding symbols for these funcs, it's safe to declare the internal libc usage hidden as a loaded libpthread will have the real symbols found. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09regex: call memcpy() ourselvesMike Frysinger
Call the hidden memcpy() ourselves otherwise gcc will emit a call to the public memcpy() which goes through the PLT. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09sysctl: avoid inline initializationMike Frysinger
Assign each field one by one rather than stack initialization as gcc will call memset() to zero out the rest of the structure -- which we don't care about as the field is unused and not seen outside of the libc. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09inet_ntop4: avoid inline initializationMike Frysinger
We only need to set the first byte to 0, but gcc likes to zero out the rest of the string with memset() when using this initialization style. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09sparc: use fputs to write to stderrMike Frysinger
This also has the advantage of fputs() having a hidden alias while puts does not. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09sparc: use HIDDEN_JUMPTARGET for errnoMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09make the sem_open changes actually compileAustin Foxley
__gen_tempname now needs to not be hidden so libpthread can get at it Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09Unbreak sem_open when UCLIBC_SUSV3_LEGACY is not definedMikhail Gusarov
sem_open uses mktemp to create temporary file. Reimplement it using __gen_tmpname, removing ugly while(1) loop. As a side-effect remove the potential source of EAGAIN errors. Signed-off-by: Mikhail Gusarov <dottedmag@dottedmag.net> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09Extend __gen_tempname with mode argumentMikhail Gusarov
sem_open(3) needs to create a temporary file in a way which can't be efficiently implemented in terms of POSIX API. Extend __gen_tempname with mode_t mode argument in order to ease sem_open implementation. Signed-off-by: Mikhail Gusarov <dottedmag@dottedmag.net> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2009-10-15malloc: handle size overflows in realloc()Mike Frysinger
The malloc() code checks the incoming size to make sure the header adjustment doesn't cause overflow in the size storage. Add the same check to realloc() to catch stupid stuff like realloc(..., -1).

2009-10-15sparc qops: unify & shrinkMike Frysinger
We don't really need to know the exact symbol that caused a failure as long as we know where to start looking. So unify the duplicate code between all funcs and between the sparc variants. This gives us a nice code shrink of ~95%. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
