* Remove support for the useless 'custom' option in SYSCALLS.TXT.Elliott Hughes2013-10-152-11/+2
| | | | | | | | | This cruft dates from a time when bionic would only output syscall contants for the syscalls mentioned in SYSCALLS.TXT. I fixed that a long time ago, but never followed through with the removal of what was then confusingly called "stub" and was recently renamed "custom".

| * Make pthread_create report sched_setscheduler failures on LP64.Elliott Hughes2013-10-151-2/+4
| | | | | | | | | | | | | | | | | | We couldn't fix this for 32-bit because there's too much broken code out there. (Pretty much everyone asks for real-time scheduling for all their threads, and the kernel says "don't be stupid".) Change-Id: I43c5271e6b6bb91278b9a19eec08cbf05391e3c4

| * Modify prefetch for krait memcpy.Christopher Ferris2013-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | I originally modified the krait mainloop prefetch from cacheline * 8 to * 2. This causes a perf degradation for copies bigger than will fit in the cache. Fixing this back to the original * 8. I tried other multiples, but * 8 is th sweet spot on krait. Bug: 11221806 Change-Id: I1f75fad6440f7417e664795a6e7b5616f6a29c45

|/ | | | | | | | | | | Let's have both use rt_sigprocmask, like in glibc. The 64-bit ABIs can share the same code as the 32-bit ABIs. Also, let's test the return side of these calls, not just the setting. Bug: 11069919 Change-Id: I11da99f85b5b481870943c520d05ec929b15eddb
* Wrap sprintf()/snprintf() macros to prevent expansion errors.Stephen Hines2013-10-111-2/+4
| | | | | | | | | | Previously, FORTIFY_SOURCE used single macros to define these standard functions for use with clang. This can cause conflicts with other macros used to call these functions, particularly when those macros expand the number of arguments to the function. This change wraps our macro definitions, so that expansion properly takes place for programmer arguments first. Change-Id: I55929b1fd2a643b9d14a17631c4bcab3b0b712cf

| * Fix x86_64 build, clean up intermediate libraries.Elliott Hughes2013-10-0986-200/+229
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The x86_64 build was failing because clone.S had a call to __thread_entry which was being added to a different intermediate .a on the way to making libc.so, and the linker couldn't guarantee statically that such a relocation would be possible. ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC This patch addresses that by ensuring that the caller and callee end up in the same intermediate .a. While I'm here, I've tried to clean up some of the mess that led to this situation too. In particular, this removes libc/private/ from the default include path (except for the DNS code), and splits out the DNS code into its own library (since it's a weird special case of upstream NetBSD code that's diverged so heavily it's unlikely ever to get back in sync). There's more cleanup of the DNS situation possible, but this is definitely a step in the right direction, and it's more than enough to get x86_64 building cleanly.

* | Fix __errno for LP64 and clean up __get_tls.Elliott Hughes2013-10-0913-102/+55
|/ | | | | | | | | | | If __get_tls has the right type, a lot of confusing casting can disappear. It was probably a mistake that __get_tls was exposed as a function for mips and x86 (but not arm), so let's (a) ensure that the __get_tls function always matches the macro, (b) that we have the function for arm too, and (c) that we don't have the function for any 64-bit architecture.
