+ *
+ * The master copy of khrplatform.h is maintained in the Khronos EGL
+ * Registry repository at https://github.com/KhronosGroup/EGL-Registry
+ * The last semantic modification to khrplatform.h was at commit ID:
+ *      67a3e0864c2d75ea5287b9f3d2eb74a745936692
+ *
+ * Adopters may modify this file to suit their platform. Adopters are
+ * encouraged to submit platform specific modifications to the Khronos
+ * group so that they can be included in future versions of this file.
+ * Please submit changes by filing pull requests or issues on
+ * the EGL Registry repository linked above.
+ *
+ *
+ * See the Implementer's Guidelines for information about where this file
+ * should be located on your system and for more details of its use:
+ *    http://www.khronos.org/registry/implementers_guide.pdf
+ *
+ * This file should be included as
+ *        #include <KHR/khrplatform.h>
+ * by Khronos client API header files that use its types and defines.
+ *
+ * The types in khrplatform.h should only be used to define API-specific types.
+ *
+ * Types defined in khrplatform.h:
+ *    khronos_int8_t              signed   8  bit
+ *    khronos_uint8_t             unsigned 8  bit
+ *    khronos_int16_t             signed   16 bit
+ *    khronos_uint16_t            unsigned 16 bit
+ *    khronos_int32_t             signed   32 bit
+ *    khronos_uint32_t            unsigned 32 bit
+ *    khronos_int64_t             signed   64 bit
+ *    khronos_uint64_t            unsigned 64 bit
+ *    khronos_intptr_t            signed   same number of bits as a pointer
+ *    khronos_uintptr_t           unsigned same number of bits as a pointer
+ *    khronos_ssize_t             signed   size
+ *    khronos_usize_t             unsigned size
+ *    khronos_float_t             signed   32 bit floating point
+ *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
+ *    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+ *                                         nanoseconds
+ *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ *    khronos_boolean_enum_t      enumerated boolean type. This should
+ *      only be used as a base type when a client API's boolean type is
+ *      an enum. Client APIs which use an integer or other type for
+ *      booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
+ *    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.

+//      truncated to fit the mantissa of the floating point. The direction of
+//      rounding is implementation defined, but by default it's always IEEE
+//      floats, which round to nearest and thus result in a value of larger
+//      magnitude than the integral value.
+//      Example: float f = UINT_MAX; // f is 4294967296f but UINT_MAX
+//                                   // is 4294967295u.
+//   2. If the floating point value is equal to the promoted integral maximum
+//      value, a range check will erroneously pass.
+//      Example: (4294967296f <= 4294967295u) // This is true due to a precision
+//                                            // loss in rounding up to float.
+//   3. When the floating point value is then converted to an integral, the
+//      resulting value is out of range for the target integral type and
+//      thus is implementation defined.
+//      Example: unsigned u = (float)INT_MAX; // u will typically overflow to 0.
+// To fix this bug we manually truncate the maximum value when the destination
+// type is an integral of larger precision than the source floating-point type,
+// such that the resulting maximum is represented exactly as a floating point.

+ * This implementation was written by Shane Day, and is also public domain.

+
+/*-----------------------------------------------------------------------------
+
+If you want to understand the MurmurHash algorithm you would be much better
+off reading the original source. Just point your browser at:
+http://code.google.com/p/smhasher/source/browse/trunk/MurmurHash3.cpp
+
+
+What this version provides?
+
+1. Progressive data feeding. Useful when the entire payload to be hashed
+does not fit in memory or when the data is streamed through the application.
+Also useful when hashing a number of strings with a common prefix. A partial
+hash of a prefix string can be generated and reused for each suffix string.
+
+2. Portability. Plain old C so that it should compile on any old compiler.
+Both CPU endian and access-alignment neutral, but avoiding inefficient code
+when possible depending on CPU capabilities.
+
+3. Drop in. I personally like nice self contained public domain code, making it
+easy to pilfer without loads of refactoring to work properly in the existing
+application code & makefile structure and mucking around with licence files.
+Just copy PMurHash.h and PMurHash.c and you're ready to go.
+
+
+How does it work?
+
+We can only process entire 32 bit chunks of input, except for the very end
+that may be shorter. So along with the partial hash we need to give back to
+the caller a carry containing up to 3 bytes that we were unable to process.
+This carry also needs to record the number of bytes the carry holds. I use
+the low 2 bits as a count (0..3) and the carry bytes are shifted into the
+high byte in stream order.
+
+To handle endianess I simply use a macro that reads a uint32_t and define
+that macro to be a direct read on little endian machines, a read and swap
+on big endian machines, or a byte-by-byte read if the endianess is unknown.

+         consistent state with a default action.  There might have been a
+         previous inconsistent state, consistent state with a non-default
+         action, or user semantic action that manipulated yychar.
+       - Of course, the expected token list depends on states to have

+         token list.  However, the list is correct for canonical LR with
+         one exception: it will still contain any token that will not be

+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+     - Of course, the expected token list depends on states to have

+//     that comes from a series of assignments, possibly with swizzled or ternary operators with
+//     known conditionals, where the source is before the loop.
+//     So, a workaround is to add a +0 term to variables the first time they are assigned to in
+//     an inner loop (if they are declared in an outside scope, otherwise there is no need).
+//     This will break the aliasing chain.
+
+// For simplicity here we add a +0 to any assignment that is in at least two nested loops. Because

+// struct as an argument. The struct is split into two arguments.
+//
+// For example:
+//   struct S { sampler2D samp; int i; };
+//   uniform S uni;
+// Is rewritten as:

+//    due to a limitation that only one type for sized formats is allowed.

+// Trace events are for tracking application performance and resource usage.
+// Macros are provided to track:
+//    Begin and end of function calls
+//    Counters
+//
+// Events are issued against categories. Whereas LOG's
+// categories are statically defined, TRACE categories are created
+// implicitly with a string. For example:
+//   TRACE_EVENT_INSTANT0("MY_SUBSYSTEM", "SomeImportantEvent")
+//
+// Events can be INSTANT, or can be pairs of BEGIN and END in the same scope:
+//   TRACE_EVENT_BEGIN0("MY_SUBSYSTEM", "SomethingCostly")
+//   doSomethingCostly()
+//   TRACE_EVENT_END0("MY_SUBSYSTEM", "SomethingCostly")
+// Note: our tools can't always determine the correct BEGIN/END pairs unless
+// these are used in the same scope. Use ASYNC_BEGIN/ASYNC_END macros if you need them
+// to be in separate scopes.
+//
+// A common use case is to trace entire function scopes. This
+// issues a trace BEGIN and END automatically:
+//   void doSomethingCostly() {
+//     TRACE_EVENT0("MY_SUBSYSTEM", "doSomethingCostly");
+//     ...
+//   }
+//
+// Additional parameters can be associated with an event:
+//   void doSomethingCostly2(int howMuch) {
+//     TRACE_EVENT1("MY_SUBSYSTEM", "doSomethingCostly",
+//         "howMuch", howMuch);
+//     ...
+//   }
+//
+// The trace system will automatically add to this information the
+// current process id, thread id, and a timestamp in microseconds.
+//
+// To trace an asynchronous procedure such as an IPC send/receive, use ASYNC_BEGIN and
+// ASYNC_END:
+//   [single threaded sender code]
+//     static int send_count = 0;
+//     ++send_count;
+//     TRACE_EVENT_ASYNC_BEGIN0("ipc", "message", send_count);
+//     Send(new MyMessage(send_count));
+//   [receive code]
+//     void OnMyMessage(send_count) {
+//       TRACE_EVENT_ASYNC_END0("ipc", "message", send_count);
+//     }
+// The third parameter is a unique ID to match ASYNC_BEGIN/ASYNC_END pairs.
+// ASYNC_BEGIN and ASYNC_END can occur on any thread of any traced process. Pointers can
+// be used for the ID parameter, and they will be mangled internally so that
+// the same pointer on two different processes will not match. For example:
+//   class MyTracedClass {
+//    public:
+//     MyTracedClass() {
+//       TRACE_EVENT_ASYNC_BEGIN0("category", "MyTracedClass", this);
+//     }
+//     ~MyTracedClass() {
+//       TRACE_EVENT_ASYNC_END0("category", "MyTracedClass", this);
+//     }
+//   }
+//
+// Trace event also supports counters, which is a way to track a quantity
+// as it varies over time. Counters are created with the following macro:
+//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter", g_myCounterValue);
+//
+// Counters are process-specific. The macro itself can be issued from any
+// thread, however.
+//
+// Sometimes, you want to track two counters at once. You can do this with two
+// counter macros:
+//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter0", g_myCounterValue[0]);
+//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter1", g_myCounterValue[1]);
+// Or you can do it with a combined macro:
+//   TRACE_COUNTER2("MY_SUBSYSTEM", "myCounter",
+//       "bytesPinned", g_myCounterValue[0],
+//       "bytesAllocated", g_myCounterValue[1]);
+// This indicates to the tracing UI that these counters should be displayed
+// in a single graph, as a summed area chart.
+//
+// Since counters are in a global namespace, you may want to disembiguate with a
+// unique ID, by using the TRACE_COUNTER_ID* variations.
+//
+// By default, trace collection is compiled in, but turned off at runtime.
+// Collecting trace data is the responsibility of the embedding
+// application. In Chrome's case, navigating to about:tracing will turn on
+// tracing and display data collected across all active processes.
+//
+//
+// Memory scoping note:
+// Tracing copies the pointers, not the string content, of the strings passed
+// in for category, name, and arg_names. Thus, the following code will
+// cause problems:
+//     char* str = strdup("impprtantName");
+//     TRACE_EVENT_INSTANT0("SUBSYSTEM", str);  // BAD!
+//     free(str);                   // Trace system now has dangling pointer
+//
+// To avoid this issue with the |name| and |arg_name| parameters, use the
+// TRACE_EVENT_COPY_XXX overloads of the macros at additional runtime overhead.
+// Notes: The category must always be in a long-lived char* (i.e. static const).
+//        The |arg_values|, when used, are always deep copied with the _COPY
+//        macros.
+//
+// When are string argument values copied:
+// const char* arg_values are only referenced by default:
+//     TRACE_EVENT1("category", "name",
+//                  "arg1", "literal string is only referenced");
+// Use TRACE_STR_COPY to force copying of a const char*:
+//     TRACE_EVENT1("category", "name",
+//                  "arg1", TRACE_STR_COPY("string will be copied"));
+// std::string arg_values are always copied:
+//     TRACE_EVENT1("category", "name",
+//                  "arg1", std::string("string will be copied"));
+//
+//
+// Thread Safety:
+// A thread safe singleton and mutex are used for thread safety. Category
+// enabled flags are used to limit the performance impact when the system
+// is not enabled.
+//
+// TRACE_EVENT macros first cache a pointer to a category. The categories are
+// statically allocated and safe at all times, even after exit. Fetching a
+// category is protected by the TraceLog::lock_. Multiple threads initializing
+// the static variable is safe, as they will be serialized by the lock and
+// multiple calls will return the same pointer to the category.
+//
+// Then the category_enabled flag is checked. This is a unsigned char, and
+// not intended to be multithread safe. It optimizes access to addTraceEvent
+// which is threadsafe internally via TraceLog::lock_. The enabled flag may
+// cause some threads to incorrectly call or skip calling addTraceEvent near
+// the time of the system being enabled or disabled. This is acceptable as
+// we tolerate some data loss while the system is being enabled/disabled and
+// because addTraceEvent is threadsafe internally and checks the enabled state
+// again under lock.
+//
+// Without the use of these static category pointers and enabled flags all
+// trace points would carry a significant performance cost of aquiring a lock
+// and resolving the category.

+
+    Fix depth pitch calculations for compressed textures.
+    
+    Depth pitch computations were not taking into account the block size
+    and simply multiplying the row pitch with the pixel height.  This caused
+    our load functions to use a very high depth pitch, reading past the end
+    of the user-supplied buffer.

+    Unset the ActiveTextureCache entry if the program does not reference it
+    
+    When changing uniforms of a program, State::onActiveTextureChange is
+    called to update the ActiveTextureCache. If the sampler uniform type
+    changes to TextureType::InvalidEnum, the entry in ActiveTextureCache was
+    not cleared. This causes stale entries in ActiveTextureCache because the
+    cache no longer matches what textures are bound and the cache does not
+    add references to the textures in it.

+
+    Don't use ClearView if we previously used dual source blending on Intel gen6. (#22)
+    
+    Doing a ClearView after a dual source blend seems to cause a TDR on
+    Intel SandyBridge. Presumeably this is because the ClearView is
+    implemented as a regular draw and the driver doesn't properly set up the
+    state.
+    
+    If we detect that this is going to happen we fall back to the manual
+    draw call path. This lets us use ClearView most of the time still.

+    Restrict the slow texture upload workaround to 128bit formats. (#21)
+    
+    The workaround is slow for having a CPU-visible mirror of the texture, but that mirror is not properly recycled with regards to GPU usage, thus causing a CPU stall on update.
+    
+    Original reports were related to WebRender vertex texture updates that are RGBA32F and RGBA32U formats. Limiting the workaround to these formats would allow the affected platforms to upload regular texture data faster without stalls.

+    Fix occasional corruption of vertex textures in HD4600 GPUs. (#19)
+    
+    This appears to be caused by the UpdateSubResource call,

+    
+    The workaround doesn't include a driver version, since the
+    bug is occurring in the most recent driver that is currently
+    available (15.40.42.5063, released 19th Mar 2019).

+    Vulkan: Fix staging buffer alignment for pixel sizes > 4
+    
+    Previously, all non-compressed formats were satisfied with a 4-byte
+    alignment.  The introduction of float formats changes this.
+    
+    This change calculates the necessary alignment using the same code path
+    as compressed formats.
+    
+    Also fixes RGB9E5's pixelByte being calculated as 3 instead of 4.

+To update ANGLE in Gecko, use Windows with git-bash, and setup depot_tools, python2, and
+python3. Because depot_tools expects `python` to be `python2` (shame!), python2 must come
+before python3 in your path.
+
+Upstream: https://chromium.googlesource.com/angle/angle
+
+Our repo: https://github.com/mozilla/angle
+It has branches like 'firefox-60' which is the branch we use for pulling into
+Gecko with this script.
+
+This script leaves a record of the merge-base and cherry-picks that we pull into
+Gecko. (gfx/angle/cherries.log)
+
+ANGLE<->Chrome version mappings are here: https://omahaproxy.appspot.com/
+An easy choice is to grab Chrome's Beta's ANGLE branch.
+
+## Usage
+
+Prepare your env:
+
+~~~
+export PATH="$PATH:/path/to/depot_tools"
+~~~
+
+If this is a new repo, don't forget:
+
+~~~
+# In the angle repo:
+./scripts/bootstrap.py
+gclient sync
+~~~
+
+Update: (in the angle repo)
+
+~~~
+# In the angle repo:
+/path/to/gecko/gfx/angle/update-angle.py origin/chromium/XXXX
+git push moz # Push the firefox-XX branch to github.com/mozilla/angle
