Re: [9] RFR[XS] 8166096: variable tracking size limit exceeded in jvmciCompilerToVM.cpp

[Vladimir Kozlov]

Thank you, David, for review.

I don't think we can do anything more here. It is number of intrinsics which overflow some internal buffer related to 
var-tracking-assignments in gcc during compilation:


Advertising







  VM_INTRINSICS_DO(VM_INTRINSIC_INFO, VM_SYMBOL_IGNORE, VM_SYMBOL_IGNORE, 
VM_SYMBOL_IGNORE, VM_ALIAS_IGNORE)

Thanks,
Vladimir

Remove annoying Hotspot compilation warning:

Seems reasonable as a short term silencer, but ... does it imply the code needs 
to be changed somehow?

Thanks,
