-// ================================ Description ================================
-// This function shall produce output according to a strict subset of the C
-// standard library's printf() family. This function must support printing the
-// following formats:
-//   1. integers: "%([0-9]*)?(z|ll)?{d,u,x,X}"
-//   2. pointers: "%p"
-//   3. strings:  "%[-]([0-9]*)?(\\.\\*)?s"
-//   4. chars:    "%c"
-// This function must be implemented in a signal-safe manner.
-// =================================== Notes ===================================
-// This function has a slightly different signature than the C standard
-// library's printf(). Notably, it returns 'void' rather than 'int'.

-// ================================ Requirements ===============================
-// This function is optional for the supporting allocator, but one of the two
-// provided implementations may be used (RTGwpAsanBacktraceLibc or
-// RTGwpAsanBacktraceSanitizerCommon). If not provided, a default implementation
-// is used which prints the raw pointers only.
-// ================================ Description ================================
-// This function shall take the backtrace provided in `TraceBuffer`, and print
-// it in a human-readable format using `Print`. Generally, this function shall
-// resolve raw pointers to section offsets and print them with the following
-// sanitizer-common format:
-//      "  #{frame_number} {pointer} in {function name} ({binary name}+{offset}"
-// e.g. "  #5 0x420459 in _start (/tmp/uaf+0x420459)"
-// This format allows the backtrace to be symbolized offline successfully using
-// llvm-symbolizer.
-// =================================== Notes ===================================
-// This function may directly or indirectly call malloc(), as the
-// GuardedPoolAllocator contains a reentrancy barrier to prevent infinite
-// recursion. Any allocation made inside this function will be served by the
-// supporting allocator, and will not have GWP-ASan protections.
