-/*
- * file format:
- * [header] [buffer]*
- *
- * The file is composed by a header followed by 0 or more buffers.
- * Each buffer contains events that happened on a thread: for a given thread
- * buffers that appear later in the file are guaranteed to contain events
- * that happened later in time. Buffers from separate threads could be interleaved,
- * though.
- * Buffers are not required to be aligned.
- *
- * header format:
- * [id: 4 bytes] constant value: LOG_HEADER_ID
- * [major: 1 byte] [minor: 1 byte] major and minor version of the log profiler
- * [format: 1 byte] version of the data format for the rest of the file
- * [ptrsize: 1 byte] size in bytes of a pointer in the profiled program
- * [startup time: 8 bytes] time in milliseconds since the unix epoch when the program started
- * [timer overhead: 4 bytes] approximate overhead in nanoseconds of the timer
- * [flags: 4 bytes] file format flags, should be 0 for now
- * [pid: 4 bytes] pid of the profiled process
- * [port: 2 bytes] tcp port for server if != 0
- * [args size: 4 bytes] size of args
- * [args: string] arguments passed to the profiler
- * [arch size: 4 bytes] size of arch
- * [arch: string] architecture the profiler is running on
- * [os size: 4 bytes] size of os
- * [os: string] operating system the profiler is running on
- *
- * The multiple byte integers are in little-endian format.
- *
- * buffer format:
- * [buffer header] [event]*
- * Buffers have a fixed-size header followed by 0 or more bytes of event data.
- * Timing information and other values in the event data are usually stored
- * as uleb128 or sleb128 integers. To save space, as noted for each item below,
- * some data is represented as a difference between the actual value and
- * either the last value of the same type (like for timing information) or
- * as the difference from a value stored in a buffer header.
- *
- * For timing information the data is stored as uleb128, since timing
- * increases in a monotonic way in each thread: the value is the number of
- * nanoseconds to add to the last seen timing data in a buffer. The first value
- * in a buffer will be calculated from the time_base field in the buffer head.
- *
- * Object or heap sizes are stored as uleb128.
- * Pointer differences are stored as sleb128, instead.
- *
- * If an unexpected value is found, the rest of the buffer should be ignored,
- * as generally the later values need the former to be interpreted correctly.
- *
- * buffer header format:
- * [bufid: 4 bytes] constant value: BUF_ID
- * [len: 4 bytes] size of the data following the buffer header
- * [time_base: 8 bytes] time base in nanoseconds since an unspecified epoch
- * [ptr_base: 8 bytes] base value for pointers
- * [obj_base: 8 bytes] base value for object addresses
- * [thread id: 8 bytes] system-specific thread ID (pthread_t for example)
- * [method_base: 8 bytes] base value for MonoMethod pointers
- *
- * event format:
- * [extended info: upper 4 bits] [type: lower 4 bits]
- * [time diff: uleb128] nanoseconds since last timing
- * [data]*
- * The data that follows depends on type and the extended info.
- * Type is one of the enum values in mono-profiler-log.h: TYPE_ALLOC, TYPE_GC,
- * TYPE_METADATA, TYPE_METHOD, TYPE_EXCEPTION, TYPE_MONITOR, TYPE_HEAP.
- * The extended info bits are interpreted based on type, see
- * each individual event description below.
- * strings are represented as a 0-terminated utf8 sequence.
- *
- * backtrace format:
- * [num: uleb128] number of frames following
- * [frame: sleb128]* mum MonoMethod* as a pointer difference from the last such
- * pointer or the buffer method_base

- * If the TYPE_ALLOC_BT flag is set, a backtrace follows.

+ *
+ * `buffer_lock_state` holds the reader count in its lower 16 bits, and
+ * the small ID of the thread currently holding the exclusive (writer)
+ * lock in its upper 16 bits. Both can be zero. It's important that the
+ * whole lock state is a single word that can be read/written atomically
+ * to avoid race conditions where there could end up being readers while
+ * the writer lock is held.
+ *
+ * The lock is writer-biased. When a thread wants to take the exclusive
+ * lock, it increments `buffer_lock_exclusive_intent` which will make new
+ * readers spin until it's back to zero, then takes the exclusive lock
+ * once the reader count has reached zero. After releasing the exclusive
+ * lock, it decrements `buffer_lock_exclusive_intent`, which, when it
+ * reaches zero again, allows readers to increment the reader count.
+ *
+ * The writer bias is necessary because we take the exclusive lock in
+ * `gc_event ()` during STW. If the writer bias was not there, and a
+ * program had a large number of threads, STW-induced pauses could be
+ * significantly longer than they have to be. Also, we emit periodic
+ * sync points from the helper thread, which requires taking the
+ * exclusive lock, and we need those to arrive with a reasonably
