Instruction Execution With Hard Limitation at Runtime
I am trying to give a quota of how many instructions can be run to a
program.
So create a simple function as below:
define void @add_gas(i64 %gasCost) {
__virtual_entry:
%0 = load i64, i64* @__WAVM__XX__gGasUsed ### I am sure it exists,
same as the __WAVM__XX__gGasLimit
%addtmp = add i64 %0, %gasCost
%1 = load i64, i64* @__WAVM__XX__gGasLimit
%cmptmp = icmp sgt i64 %addtmp, %1
br i1 %cmptmp, label %then, label %ifcont
then:...
