[scudo] Initial standalone skeleton check-in Summary: This is the initial check-in for the Standalone version of Scudo. The project is initially going to live in scudo/standalone then will replace scudo. See http://lists.llvm.org/pipermail/llvm-dev/2019-January/129113.html for details. This initial CL is meant to lay out the project structure, of both code & tests, providing a minimal amount of functionalities, namely various definitions, some atomic helpers and an intrusive list. (empty.cc is just here to have a compilation unit, but will go away in the upcoming CLs). Initial support is restricted to Linux i386 & x86_64 in make files and will be extended once things land & work. We will grow organically from here, adding functionalities in limited amounts.

[scudo][standalone] Do not error out on spurious C(XX) flags Summary: The standalone Scudo version is being built with `-Werror` which can be tripped by extraneous command line arguments. We have little control over those as they can be passed down to us by `CMAKE_C(XX)_FLAGS`, the reported scenario involving `-stdlib=libc++` (see https://reviews.llvm.org/D57412#1384504). To work around this, disable `-Wunused-command-line-argument`.

[scudo][standalone] Introduce platform specific code & mutexes Summary: This CL adds the platform specific code for Fuchsia, Linux & Android, as well as some tests related to those (more tests to come later). While some of it is pretty much a straight port of the existing scudo & sanitizer_common code, the memory mapping functions have been reworked a bit to fit the limited usage scenario that Scudo has for them. For Fuchsia, I can now track the Vmar/Vmo pair for memory mappings if there is an intent to grow or decommit some mapping (that will be useful for the Primary).

[scudo][standalone] Implement checksumming functions Summary: This CL implements the checksumming functions. This departs from the current Scudo code in one aspect: the software version is no longer CRC32 but a BSD checksum. This is because the software CRC32 was too impactful in terms of performances, the BSD checksum has no array lookup which is better (and saves 1KB of data). As with the current version, we only flip the CRC compiler flag for a single compilation unit by default, to allow for a library compiled with HW CRC32 to work on a system without HW CRC32. There is some platform & hardware specific code in those files, but since departs from a mere platform split, it felt right to me to have it that way.

(empty.cc is just here to have a compilation unit, but will go away in the upcoming CLs). Initial support is restricted to Linux i386 & x86_64 in make files and will be extended once things land & work. We will grow organically from here, adding functionalities in limited amounts.

[scudo][standalone] Introduce platform specific code & mutexes Summary: This CL adds the platform specific code for Fuchsia, Linux & Android, as well as some tests related to those (more tests to come later). While some of it is pretty much a straight port of the existing scudo & sanitizer_common code, the memory mapping functions have been reworked a bit to fit the limited usage scenario that Scudo has for them. For Fuchsia, I can now track the Vmar/Vmo pair for memory mappings if there is an intent to grow or decommit some mapping (that will be useful for the Primary).

[scudo] Initial standalone skeleton check-in Summary: This is the initial check-in for the Standalone version of Scudo. The project is initially going to live in scudo/standalone then will replace scudo. See http://lists.llvm.org/pipermail/llvm-dev/2019-January/129113.html for details. This initial CL is meant to lay out the project structure, of both code & tests, providing a minimal amount of functionalities, namely various definitions, some atomic helpers and an intrusive list.

Initial support is restricted to Linux i386 & x86_64 in make files and will be extended once things land & work. We will grow organically from here, adding functionalities in limited amounts.
