[libc][NFC] Correct test header inclusion, license (#114604) 2024-11-05T18:25:25+00:00 Michael Jones michaelrj@google.com 2024-11-05T18:25:25+00:00 04aaa35d40d8c5ff030014866691f9a56e59c142 Some tests were including LibcTest.h directly. Instead you should include Test.h which does proper indirection for other test frameworks we support (zxtest, gtest). Also added some license headers to tests that were missing them.

Some aarch64 compilers seem to consider that `uint128_t` is not
`is_trivially_constructible` which prevents `bit_cast`-ing.
 [libc] Refactor `BigInt` (#86137) 2024-04-04T08:27:08+00:00 Guillaume Chatelet gchatelet@google.com 2024-04-04T08:27:08+00:00 a2306b65d223212dcfafe12c7299262d8d4fdcb4 This patch moves most of the multiprecision logic to the `multiword` namespace and simplifies some logic in `BigInt`. It also fully implements the mask and count functions and increases test coverage. `math_extras.h` is also reworked to make it more concise.

 [libc] Add user defined literals to initialize `BigInt` and `__uint128_t` constants (#81267) 2024-02-14T13:08:09+00:00 Guillaume Chatelet gchatelet@google.com 2024-02-14T13:08:09+00:00 03232350536655234a30eca17ea56c8cb636831c Adds user defined literal to construct unsigned integer constants. This is useful when constructing constants for non native C++ types like `__uint128_t` or our custom `BigInt` type.
