I just tried to compile the Linux kernel 2.6.30.1
with the gcc compiler version 4.5 snapshot 20090709.
The compiler said
drivers/net/ixgbe/ixgbe_main.c:5081:1: error: definition in block 50 does not
dominate use in block 51
for SSA_NAME: .MEM_541 in statement:
.MEM_482 = PHI <.MEM_480(40), .MEM_541(51)>
PHI argument
.MEM_541
for PHI node
.MEM_482 = PHI <.MEM_480(40), .MEM_541(51)>
drivers/net/ixgbe/ixgbe_main.c:5081:1: internal compiler error: verify_ssa
failed
Please submit a full bug report,
with preprocessed source if appropriate.
