Sun Apr 23 21:30:01 UTC 2023


Import the same patch already in use by wpewebkit to fix the build on
ARM NEON targets, and also a new one proposed upstream to fix the build
with OpenGL ES header from some GPU drivers.

+Subject: [PATCH] FELightningNEON.cpp fails to build, NEON fast path seems
+ unused https://bugs.webkit.org/show_bug.cgi?id=241182
+
+Reviewed by NOBODY (OOPS!).
+
+Move the NEON fast path for the SVG lighting filter effects into
+FELightingSoftwareApplier, and arrange to actually use them by
+forwarding calls to applyPlatformGeneric() into applyPlatformNeon().
+
+Some changes were needed to adapt platformApplyNeon() to the current
+state of filters after r286140. This was not detected because the code
+bitrotted due to it being guarded with CPU(ARM_TRADITIONAL), which does
+not get used much these days: CPU(ARM_THUMB2) is more common. It should
+be possible to use the NEON fast paths also in Thumb mode, but that is
+left for a follow-up fix.

+Reviewed by NOBODY (OOPS!).
+
+EGLNativeWindowType can be aliased to a different type depending on the
+EGL implementation headers, and static_cast (or reinterpret_cast) may
+not always work. This is similar to 194561 at main, but with the conversion
+being done in the opposite direction, therefore we apply the same
+solution using a C style cast expression, which works in all cases.
+
+For the build failures related to the usage of OpenGL ES 3 symbols, add
+the needed HAVE(OPENGL_3_ES) guards and avoid using GL_MAJOR_VERSION
+and instead parse the GL_VERSION string in a way similar as in the
+GLContext::version() function.
+
