2013-09-05long double cleanup, initial commitSzabolcs Nagy8-96/+89
new ldshape union, ld128 support is kept, code that used the old ldshape union was rewritten (IEEEl2bits union of freebsd libm is not touched yet) ld80 __fpclassifyl no longer tries to handle invalid representation
2013-09-04fix typo in comment in __randnameRich Felker1-1/+1
2013-09-02fix mips-specific bug in synccall (too little space for signal mask)Rich Felker1-5/+3
switch to the new __block_all_sigs/__restore_sigs internal API to clean up the code too.
2013-09-02in synccall, ignore the signal before any threads' signal handlers returnRich Felker1-4/+4
this protects against deadlock from spurious signals (e.g. sent by another process) arriving after the controlling thread releases the other threads from the sync operation.
2013-09-02fix invalid pointer in synccall (multithread setuid, etc.)Rich Felker1-0/+1
the head pointer was not being reset between calls to synccall, so any use of this interface more than once would build the linked list incorrectly, keeping the (now invalid) list nodes from the previous call.
2013-09-01fix special-case breakage in popen due to reversed argument orderRich Felker1-1/+1
