[Bug tree-optimization/32544] New: gcc 4.2.1 miscompiles Mesa's r300 DRI driver with -ftree-vrp

Fri, 29 Jun 2007 01:15:08 -0700 

Mesa's r300 DRI driver produces incorrect output (garbles the display) if
r300_state.c is compiled with -ftree-vrp (-O2 -fno-tree-vrp works fine; all
files except r300_state.c can be compiled with normal -O2).
