[ASan] Switch ASan to generic ThreadRegistry from sanitizer_common. Delete ASan-specific AsanThreadRegistry.

llvm-svn: 177634

llvm-svn: 177508

[ASan] Move GetCurrentThread/SetCurrentThread from AsanThreadRegistry class into plain functions: they don't actually use registry

[asan] while generating the description of a global variable, emit the module name in a separate field, thus not duplicating this information if every description. This decreases the binary size (observed up to 3%). https://code.google.com/p/address-sanitizer/issues/detail?id=168 . This changes the asan API version. compiler-rt part, llvm-part will follow

llvm-svn: 177253

[Sanitizer] Don't intercept frexpf and frexpl on Windows. Add frexp declaration to asan_intercepted_functions.h

llvm-svn: 177155

[asan] remove one redundant malloc stress test, unify the usage of ASAN_LOW_MEMORY macro in tests, slightly reduce test memory usage (all to make 32-bit runs consume less RAM)

[ASan] turn off checking initialization order in ASan runtime by default. Instead, it should be turned on by default in the compiler

[asan] use 4Tb of address space for the asan allocator instead of 1Tb. This increases the memory available for a single size class from 16Gb to 64Gb. The total VM footprint becomes 20Tb

llvm-svn: 176857

New allocator has 1.5x memory overhead of the old one.

[ASan] Add the memcmp_strict flag (1 by default) that controls the behavior of accessibility checks in memcmp.
1: memcmp(p1, p2, n) always checks n bytes
0: memcmp checks up to n bytes depending on whether the memory contents differ.

llvm-svn: 176256

llvm-svn: 176255

[asan] bump kMidMemEnd to 0x4fffffffffULL since in rare cases prelink uses addresses higher than 0x3fffffffff

llvm-svn: 176250

[asan] if calloc returns a freshly-mmaped memory, don't clear it with memset. Speeds up calloc-intensive code

llvm-svn: 176185

llvm-svn: 176085

[asan] fix the output for range accesses (memset, etc); improve the tests; more strict checking in memcmp

[ASan] temporarily disable alloc_dealloc_mismatch on Mac, since the previous commit caused error reports in gTest.

llvm-svn: 175766

Because the interceptors will reside in a dylib, not the main executable, we can't just declare them,
but must use the interposition machinery.
Fix the test expectations in large_func_test.cc affected by the change.
This CL should make our Mac buildbots green.

that had been used on OS X only.
The INTERCEPTOR() macro on OS X is now responsible for declaring the wrapped function, the wrapper and the
pair of pointers to them in __DATA,__interposition section. Thus adding an interceptor requires editing a single file now.

[ASan] Delete asan/dynamic dir and temporarily move the interposers declarations to asan_intercepted_functions.h
Now that we have only one dependency on asan_intercepted_functions.h, we can unite that code with the interceptors declarations in asan_interceptors.cc and get rid of asan_intercepted_functions.h
