Magnus Norddahl	075a666c75	- stop using lambda functions for CreateCall because MSVC lambas use a different calling convention and "converts" them to the right one by generating a thunk function	2019-04-15 14:37:44 +02:00
Magnus Norddahl	51900d5d98	- removed the SetupSimpleFrameMissingArgs logic as the number of args are now guaranteed	2019-04-15 14:37:43 +02:00

Magnus Norddahl	c9a20d56d1	- generate a memset for the allocated stack memory because that's what the VM does ... (this really shouldn't be done by the VM either - the compiler backend should clear its registers if it wants them to be zero!)	2019-04-15 14:37:19 +02:00
Magnus Norddahl	b4db05a7ff	- modify exception checks to jump ahead if the exception is to be thrown as it limits static misprediction	2019-04-15 14:37:11 +02:00
