  "message": "[gl] Fix compute blit encoding for RG11B10Ufloat T2B copies\n\nFix kEncodeRG11B10UfloatInU32 in BlitTextureToBuffer.cpp:\n- Replace log2/exp2 floating point math with IEEE 754 bitcast manipulation.\n- Correctly handle NaN, Infinity, negative values (clamped to 0.0), and overflow\n  clamping to maximum finite values (65024.0 for 11-bit, 64512.0 for 10-bit).\n- Handle subnormals and mantissa carry into exponent correctly without\n  overflowing into reserved exponent 31 (Infinity/NaN).\n\nAdd an end2end regression test cloned from CTS image_copy:mip_levels\nverifying RG11B10Ufloat texture-to-buffer copies with and without the\nuse_blit_for_rg11b10ufloat_texture_copy toggle in OpenGLESBackend config.\n\nTurn on UseBlitForRG11B10UfloatTextureCopy for OpenGL ES by default,\nas GL_RGB / GL_UNSIGNED_INT_10F_11F_11F_REV not guaranteed accepted by\nglReadPixels.\n\nBug: 556959073\nTAG\u003dagy\nCONV\u003d1a094951-4459-45eb-beb7-5195e47d5b48\n\nChange-Id: Ida4e35bebb806a94f135f7f6bf9770b46b516d7d\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/340975\nReviewed-by: Geoff Lang \u003cgeofflang@chromium.org\u003e\nCommit-Queue: Shrek Shao \u003cshrekshao@google.com\u003e\n",
