2017-11-08[sanitizer] Add Scudo to the sanitizer lint checks.Kostya Kortchinsky
Summary: Scudo abides by the coding style enforced by the sanitizer_common linter, but as of right now, it's not linter-enforced. Add Scudo to the list of directories checked by check_lint.sh. Also: fixes some linter errors found after getting this running.

2016-04-22[ASAN] Use struct instead of array in sancov.pySagar Thakur
Summary: When using 32-bit python with 64-bit asan the pc array in sancov.py cannot fit in 64-bit pc's because the type-code 'L' for arrays in python corresponds to the C type long which is only of 4 bytes. Because of this some of the coverage tool tests fail on mips. To fix these test possible solutions are to use 64-bit python or use struct.unpack with the 'Q' type-code. We have used struct.unpack with 'Q' type code since it is not appropriate to have a 64-bit python on all hosts.

2014-05-27[asancov] Write coverage directly to a memory-mapped file.Evgeniy Stepanov
This way does not require a __sanitizer_cov_dump() call. That's important on Android, where apps can be killed at arbitrary time. We write raw PCs to disk instead of module offsets; we also write memory layout to a separate file. This increases dump size by the factor of 2 on 64-bit systems. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@209653 91177308-0d34-0410-b5e6-96231b3b80d8

Summary: Sandboxed code may now pass additional arguments to __sanitizer_sandbox_on_notify() to force all coverage data to be dumped to a single file (the default is one file per module). The user may supply a file or socket to write to. The latter option can be used to broker out the file writing functionality. If -1 is passed, we pre-open a file. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@209121 91177308-0d34-0410-b5e6-96231b3b80d8
