1. Excerpted from: https://github.com/ARM-software/LLVM-embedded-toolchain-for-Arm/blob/main/samples/src/cpp-baremetal-semihosting-prof/proflib.c 2. Since llvm profile supports more than just gcov, and some features have not yet been explored, two clang gcov implementations are supported after this patch 3. Using this lib only supports the gcov compilation options of "-fprofile-instr-generate -fcoverage-mapping" 4. This file is heavily dependent on the compiler clang version, and is currently aligned with ci, supporting 17.0.1 and below. 18 and above are not supported by this library due to different internal implementations of the compiler Signed-off-by: wangmingrong1 <wangmingrong1@xiaomi.com>
