2018-05-08Fix annotation in _M_destroy for cow-strings.Mikhail Kashkarov1-1/+1
Perfrom annotation before deallocation, when *this is correct. Change-Id: I438cbf7dec143247185f6abda7033a7733b35ffb
2018-05-08Align internal representation in cow-string by 8.Mikhail Kashkarov1-1/+6
COW-strings are used as an exception strings still (yet), and since char buffer starts at "this + 1" ("this" in COW basic_string<>), where "this" is properly aligned, sizeof(*this) may be not aligned by 8 (12 bytes under i686 arch with current compiler), so asan annotations will fail. Still testing with all configurations. Change-Id: Ic7bb665a58d22f7e8ab979fc548fc96973473f32

2018-04-17Disable std::string sso by forcing dynamic allocations.Mikhail Kashkarov2-10/+31
String internal buffer for small-string optimization a). may be not aligned by 8 bytes (as class member) and b). not poisoned by asan properly with redzones. Need to perform this changes carefully as there are other libstdc++ headers that relies on std::string default structure and size by checking that with static assertations. So we cannot simply change sso-buffer size without changing them. For now simply immitate that sso-buffer is already full at given point of usage. Change-Id: I525716813c2a31c7d9e0d2a180d8112b54009fa6
2018-04-16Add project build options to disable string-SSO.Mikhail Kashkarov4-0/+4
std::string local buffer used in small-string optimization may be not aligned by 8 as asan requires on armv7l/i586 archs (small buffer in struct from libstdc++ lib passed on stack, which can be aligned by 4), so enable fully dynamic strings to fully annotate container. Note: Enabling fully dynamic string changes the library ABI. Add "libstdcxx_fully_dynamic_string=1" macros to project config for enabling. Change-Id: I4e7a7dc373ac0f2624d1fc854ae82956ff4402b3
