...nt. It's marked dead here: 28 %AL<dead> = MOV8rr %reg1024<kill>, %EAX<imp-def> MOV8rr %mreg(2)<d> %reg1024 %mreg(17)<d> But it's really dead at the point right after the call. I think the range [30,31) is correct, as far as I understand the slat numbering scheme. EAX has the same range, which seems correct. I don't know what you mean when you say EAX should be marked dead. It is, as far as live interval analysis is concerned, because it has the correct live range. Do you mean that it should be listed as dead in the printout of the C...

For the x86-64 target, I tried compiling a simple hello world. I don't understand the live interval information. Here's the machine instructions as dumped by LiveIntervalAnalysis: ********** MACHINEINSTRS ********** file hello.c line 3 b: 0 FNSTCW16m <fi#0>, 1, %NOREG, 0 FNSTCW16m <fi#0> 1 %mreg(0) 0 4 MOV8mi <fi#0>, 1, %NOREG, 1, 2 MOV8mi <fi#0> 1 %mreg(0) 1 2 8
