the complete valgrind glxinfo output
When i execute
valgrind -v --leak-check=full --track-origins=yes glxinfo
i get lots errors: uninitialized values, invalid writes, ...
Originally I got all the errors when testing an opengl coding project,
but when narrowing down the problem, i found that the errors also occur when
running glxgears or glxinfo.
The complete valgrind output is attached.
Mesa was compiled with:
-O3 -pipe -march=corei7-avx -mcx16 -maes -mpclmul -mpopcnt -mavx -msse4.2
-msse4.1 --param l1-cache-size=32 --param l1-cache-line-size=64 --param
l2-cache-size=256
this equals -march=native for my laptop.</pre>
