Hi all,
While trying to use tsan on Aarch64, I am getting mmap failure.
__sanitizer::internal_mmap (addr=0x7d0000000000, length=1099511627776, prot=0,
flags=16434, fd=-1, offset=0)
p syscall(222, 0x7d00000000, 1099511627776, 0, 16434, -1,0,0)
$34 = -1
// SizeClassAllocator64 -- allocator for 64-bit address space.
//
// Space: a portion of address space of kSpaceSize bytes starting at
// a fixed address (kSpaceBeg). Both constants are powers of two and
// kSpaceBeg is kSpaceSize-aligned.
// At the beginning the entire space is mprotect-ed, then small parts of it
// are mapped on demand.
//
The kSpaceBeg seem to be 0x7d00000000 by default and kSpaceSize seem
to be 1099511627776.
I am trying to understand where these default values are set?
regards,
Venkat.
