/*-
|
|
* This is a cc optimiser bug for ultrix 4.3, mips CPU.
|
|
* What happens is that the compiler, due to the (a)&7,
|
|
* does
|
|
* i=a&7;
|
|
* i--;
|
|
* i*=4;
|
|
* Then uses i as the offset into a jump table.
|
|
* The problem is that a value of 0 generates an offset of
|
|
* 0xfffffffc.
