Platforms

x86/x86_64 Linux

Just works, this is the primary platforms for the developers.

Stack unwinding: frame pointers. Default shadow mapping:

Shadow = (Mem >> 3) | 0x20000000         # 32 bit
Shadow = (Mem >> 3) | 0x0000100000000000 # 64 bit

Alternative shadow mapping, requires -pie

Shadow = Mem >> 3         # 32 and 64 bit

Function interception: dlsym

x86/x86_64 Darwin (OSX)

Just works, but the machinery used to intercept functions (mach_override) may soon be replaced with another one (function interposition)

Stack unwinding: frame pointers. Shadow mapping:

Shadow = (Mem >> 3) | 0x20000000         # 32 bit
Shadow = (Mem >> 3) | 0x0000100000000000 # 64 bit

ARM Android

Works (TODO(eugenis))

Stack unwinding mechanism: _Unwind_Backtrace.

ARM iOS

Doing baby steps, help is welcome.

x86 Windows

C-only code mostly works,
Simple C++ code also works, complex C++ code using multiple/virtual inheritance doesn't work.
See issue 56 (on Google Code) for the details.
Help is welcome!

Stack unwinding mechanism: CaptureStackBackTrace

PowerPC32/PowerPC64 Linux

We've been notified that small tests work.
TODO: describe the differences (e.g. the shadow mapping, offset, page size, etc)

Stack unwinding mechanism: _Unwind_Backtrace.

SPARC Linux

The run-time library is known to build on SPARC Linux.

Compilers

Clang/LLVM

Just works, this is the primary compiler for the developers.

GCC

The first version is in trunk, will appear in 4.8 release.
The implementation is (almost?) complete, but we don't have enough experience with it yet.

In AddressSanitizer mode GCC defines __SANITIZE_ADDRESS__ macro, but does not support __has_feature(address_sanitizer)
