| * Replaces vfork() implementation with fork()Dan Albert2014-06-102-72/+0
| | | | | | | | | | | | | | | | vfork() was removed from POSIX 2008, so this replaces its implementation with a call to fork(). Bug: 13935372 Change-Id: I6d99ac9e52a2efc5ee9bda1cab908774b830cedc

* Removes index() from bionic.Dan Albert2014-06-051-1/+0
| | | | | | | | | | This function has been removed from POSIX. Unfortunately, we can't leave #define index(a, b) strchr((a), (b)) in its place because defining a preprocessor macro for index() breaks a whole lot of code. Bug: 13935372 Change-Id: Ifda348acde06da61c12e7ee2f8fe6950a3174dd1

| * Revert "Revert "Lose the hand-written futex assembler.""Elliott Hughes2014-05-283-90/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem with the original patch was that using syscall(3) means that errno can be set, but pthread_create(3) was abusing the TLS errno slot as a pthread_mutex_t for the thread startup handshake. There was also a mistake in the check for syscall failures --- it should have checked against -1 instead of 0 (not just because that's the default idiom, but also here because futex(2) can legitimately return values > 0). This patch stops abusing the TLS errno slot and adds a pthread_mutex_t to pthread_internal_t instead. (Note that for LP64 sizeof(pthread_mutex_t) > sizeof(uintptr_t), so we could potentially clobber other TLS slots too.) I've also rewritten the LP32 compatibility stubs to directly reuse the code from the .h file. This reverts commit 75c55ff84ebfa686c7ae2cc8ee431c6a33bd46b4.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add following functions: bcopy, memcpy, memmove, memset, bzero, memcmp, wmemcmp, strlen, strcpy, strncpy, stpcpy, stpncpy. Create new directories inside arch-x86 to specify architecture: atom, silvermont and generic (non atom or silvermont architectures are treated like generic). Due to introducing optimized versions of stpcpy and stpncpy, c-implementations of these functions are moved from common for architectures makefile to arm and mips specific makefiles.

* Unify our assembler macros.Elliott Hughes2014-02-2014-170/+51
| | | | | | | | | | | | | | Our <machine/asm.h> files were modified from upstream, to the extent that no architecture was actually using the upstream ENTRY or END macros, assuming that architecture even had such a macro upstream. This patch moves everyone to the same macros, with just a few tweaks remaining in the <machine/asm.h> files, which no one should now use directly. I've removed most of the unused cruft from the <machine/asm.h> files, though there's still rather a lot in the mips/mips64 ones. Bug: 12229603 Change-Id: I2fff287dc571ac1087abe9070362fb9420d85d6d
