I opted to leave casts to types that were definitely the same size alone. reinterpret_cast<uintptr_t>(pointer) and reinterpret_cast<intptr_t>(pointer) should always be safe, for example. Casts to other integral types have been replaced with FromPointerCast<>(), which does zero-extension or sign-extension based on the target type. To make it possible to use FromPointerCast<>() with some use sites that were already using checked_cast<>(), FromPointerCast<>() now uses check_cast<>() when converting to a narrower type. Test: crashpad_util_test FromPointerCast*, others Change-Id: I4a71b4aa2d87f545c75524290a702f5f3138d675 Reviewed-on: https://chromium-review.googlesource.com/489701 Reviewed-by: Scott Graham <scottmg@chromium.org>
