I guess that's a bug in itself. I'll file a bug for this. Full log: https://treeherder.mozilla.org/logviewer.html#?job_id=188481017&repo=autoland&lineNumber=7416 Maybe this is somehow related to bug 1375984, bug 1413395 and/or bug 1464907 that bugzilla is showing me as possible duplicates, but LTO makes the problem appear permanently rather than intermittently?

Filed bug 1478287.

Not very familiar with the details of what is going on in the tests. It would seem like the contents is just not getting rendered to the canvas based on the log output, hence why the results are just all white. It would be better if we could get the original author of the test to examine it. kaku, can you please take a look?

Kaku hasn't responded in 4 weeks, and is not in the phonebook anymore, so I guess he's not at Mozilla anymore. Anyone else could look into this?

Maybe Jeff, who reviewed the code and test in bug 1141979?

This goes away if I make files in gfx/ycbcr build without LTO.

The cause is the assembly in gfx/ycbcr/yuv_row_posix.cpp, missing constraints.

ycbcr is dead upstream, and has been for almost as long as the code in the gecko tree hasn't been updated. Let's not pretend that we can actually run the update script and that having the patches separated matters, because there's no upstream to apply those patches to anymore. Update README accordingly.

Depends on D4198

While the current code compiles fine with the file as it is, with LTO enabled, some functions end up inlined into their callers and their callers, recursively, and the compiler doesn't know some of the registers have been modified by the assembly, leading to bad decisions, and bad behavior at runtime. The same problem would likely happen if we were using UNIFIED_SOURCES in the directory. Depends on D4199
