[LLVMdev] Live Intervals Question
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
