    • Workaround for ASAN stack safety analysis problem with FixedArray container annotations. · af0babf0 
      The problem is that the underlying storage adds redzone after the actual data so from compiler's perspective it looks like a valid memory. In the outlined version the memory is returned in call.i.i with unknown size so the access check can't be removed. The workaround is to always outline the call to InitializeData for ASAN builds.

Outlined version:
  %call.i.i = call noundef i32* @absl::FixedArray<int, 4ul, std::__u::allocator<int> >::Storage::InitializeData()(...), !dbg !28
  store i32* %call.i.i, i32** %data_.i.i, align 8, !dbg !27
  %arrayidx = getelementptr inbounds i32, i32* %call.i.i, i64 5, !dbg !29
  %24 = bitcast i32* %arrayidx to i8*, !dbg !29
  call void @llvm.asan.check.memaccess(i8* %24, i32 36), !dbg !29
  store i32 0, i32* %arrayidx, align 4, !dbg !29

Inlined version:
 %arrayidx = getelementptr inbounds %"class.absl::FixedArray", %"class.absl::FixedArray"* %7, i64 0, i32 0, i32 0, i32 1, i64 20, !dbg !40
  %27 = bitcast i8* %arrayidx to i32*, !dbg !40
  >>>>>>>>>>>>>>> call to @llvm.asan.check.memaccess removed <<<<<<<<<<<<<<
  store i32 0, i32* %27, align 4, !dbg !40

Workaround for ASAN stack safety analysis problem with FixedArray container annotations.

    • CMake: Add an option to build the libraries that are used for writing · 277ce1dd 
      tests without requiring Abseil's tests be built (default=OFF)

This disables building libraries that are only used for writing tests
by default.

The logging library releases some libraries used for writing tests
that themselves depend on GoogleTest. This allows Abseil to build by
default without requiring GoogleTest.

Fixes #1262

    • Support compilers that are unknown to CMake · c5615151 
      Abseil failed to configure with `ABSL_PROPAGATE_CXX_STD` if the compiler was not known to CMake:

    target_compile_features no known features for CXX compiler

Turns the error into a warning by checking `CMAKE_CXX_COMPILE_FEATURES`
before calling `target_compile_features`.
