 2013-05-21 08:12:08 +00:00
Kostya Serebryany b1333fe831 [sanitizer] fix asan on the platforms where the page size is not a compile-time constant (or at least where EXEC_PAGESIZE may not be trustworthy), e.g. powerpc64. 
llvm-svn: 182351
 2013-05-21 06:15:50 +00:00
Peter Collingbourne b69b8a4a8f [nolibc] Move GetPageSize to the individual platforms. 
GetPageSize wraps sysconf(_SC_PAGESIZE) on POSIX platforms, but
sysconf resides in libc.  To make this libc-independent on Linux,
move the wrapper to sanitizer_mac.cc and return the Linux-specific
constant EXEC_PAGESIZE in the sanitizer_linux.cc implementation.

Peter Collingbourne d5169edc36 [nolibc] Make GetArgsAndEnv libc-independent. 
__libc_stack_end is made into a weak symbol if possible.  If libc is
not linked, read args and environment from /proc.
