[LLVMdev] Possible bug in getCallPreservedMask for CallingConv::Intel_OCL_BI
Not sure who owns this bit of code, so sending this to the general list.
It looks like there may be an unintentional fall through happening in
the X86RegisterInfo::getCallPreservedMask function.

preserve registers across function call
Hi Marcello,
Thanks for your reply. I will try to pass down the mask!
I have one more question. In my backend I return CSR_RegMask in
getCallPreservedMask and return CSR_SaveList in getCalleeSavedRegs. Is that
a correct setup? I dumped the regmask and found that callee saved regs are
marked 1 and non-callee saved regs are 0.
Thanks,
Xiaochu

preserve registers across function call
Dear there,
I was wondering how to preserve registers (caller saved) across calls. I
implemented getCalleeSavedRegs and getCallPreservedMask. But the
non-callee-saved registers are still not saved by caller. I want to spill
these registers in use on stack right before the call. From my
understanding, the register allocator in llvm will do the spill and
restoring automatically? Is there anything I was supposed to do to make it
happen?
T...
