2011-06-14restore use of .type in asm, but use modern @function (vs %function)Rich Felker-0/+1
this seems to be necessary to make the linker accept the functions in a shared library (perhaps to generate PLT entries?) strictly speaking libc-internal asm should not need it. i might clean that up later.
2011-06-13remove all .size and .type directives for functions from the asmRich Felker-3/+0
these are useless and have caused problems for users trying to build with non-gnu tools like tcc's assembler.
2011-02-19race condition fix: block all signals before decrementing thread countRich Felker-9/+0
the existence of a (kernelspace) thread must never have observable effects after the thread count is decremented. if signals are not blocked, it could end up handling the signal for rsyscall and contributing towards the count of threads which have changed ids, causing a thread to be missed. this could lead to one thread retaining unwanted privilege level. this change may also address other subtle race conditions in application code that uses signals.
