And yes my stdlib.h has
/usr/include/stdlib.h:extern void *aligned_alloc (size_t __alignment,
size_t __size)
I am guessing you are running on this on an old system. My glibc version is
2.17

[LLVMdev] ASan unit test/libcxx build break
A recent change added defined(__linux__) condition to the code below.
Now it says that on linux with --std=c++0x (or --std=c++11) the system
stdlib.h header must define aligned_alloc(). Really?
include/__config:
#if ( defined(__FreeBSD__) || defined(__linux__) ) && (__ISO_C_VISIBLE
>= 2011 || __cplusplus >= 201103L)
#define _LIBCPP_HAS_QUICK_EXIT
#define _LIBCPP_HAS_C11_FEATURES

Yes. Ubuntu 12.04 LTS with glibc 2.15 does not have aligned_alloc.

implicit declaration of function `posix_memalign''
...4.0.0/tools''
make: *** [install-tools] Error 2
The posix_memalign function is declared in /usr/include/stdlib.h (which is included in xenpaging.c):
#ifdef __USE_XOPEN2K
/* Allocate memory of SIZE bytes with an alignment of ALIGNMENT. */
extern int posix_memalign (void **__memptr, size_t __alignment, size_t __size)
__THROW __nonnull ((1));
#endif
So, I edit the Makefile in tools/xenpaging and add the line:
CFLAGS += -D__USE_XOPEN2K
However, when I recompile, I get the same error. There also seems to be another condition in stdlib.h that must be satisfied before the __USE_XOPEN2K one wi...

[LLVMdev] problem trying to write an LLVM register-allocation pass
I have a new problem: Register RBP is used in a function foo. (I am not
allocating RBP to any virtual register, the instances of RBP in function
foo are in the machine code when my register allocator starts.)
Function foo calls function bar. Register RBP is not saved across the
call, though it is live after the call. Function bar includes a virtual
register. The code that I'm using to
