[LLVMdev] [LLVMDev] Reserved Registers

[Jeff Kunkel]

So, there exists registers which are reserved denoted by the Machine
Register Info :: getReserved field. I am wondering if these registers are
reserved or preserved?

I have come across a case where a reserved register was used. Namely it's in
"llvm\test\CodeGen\X86\2009-04-27-CoalescerAssert.ll" where the reserved
register ESP (54) in block "bb98.fragment" on line 854. Is this use of a
reserved register a mistake or not?

Thanks,
Jeff Kunkel
