This one I haven't seen happening on Android-IA, we use O3 for compilation but I don't think it makes difference with this case (?) Mauro, what kind of machine is your build target? ACH_X86_HAVE_SSE4_1 is defined both for x86 and x86_64 even for quite old cores? Hi Tapani, The target machine not featuring ARCH_X86_HAVE_SSE4_1 in 32bit builds are the x86.mk generic and atom.mk I'm going to check Kenneth's patch [1] and report back to close the issue. M. [1] https://lists.freedesktop.org/archives/mesa-dev/2017-August/166105.html Should be fixed by: commit 22e1d8832c90702b4cd972e48f0db809f7c7639f Author: Kenneth Graunke <kenneth@whitecape.org> Date: Thu Aug 10 21:10:31 2017 -0700 i965: Guard GetBufferSubData's streaming memcpy load with USE_SSE41 |

Hi, could you please check commit b4f639d02a "i965: Prefer using streaming reads from WC mmaps" ? It causes the following building error with android 32 bit builds: external/mesa/src/mesa/drivers/dri/i965/intel_buffer_objects.c:345: error: undefined reference to '_mesa_streaming_load_memcpy' 32bit builds on android do not use sse41 and if I understood correctly the issue some guards should be used as current build uses -msse2 and main/streaming-load-memcpy.{c,h} rely on sse41 intrinsics. Infact in Android build there is a library module called libmesa_sse41 which is used conditionally, when ARCH_X86_HAVE_SSE4_1 is true [not true for 32bit builds] Please advise on how to fix android 32bit builds. Thanks Mauro Rossi android-x86 team
