[MC][X86] Correctly model additional operand latency caused by transfer delays from the integer to the floating point unit. This patch adds a new ReadAdvance definition named ReadInt2Fpu. ReadInt2Fpu allows x86 scheduling models to accurately describe delays caused by data transfers from the integer unit to the floating point unit. ReadInt2Fpu currently defaults to a delay of zero cycles (i.e. no delay) for all x86 models excluding BtVer2. That means, this patch is only a functional change for the Jaguar cpu model only. Tablegen definitions for instructions (V)PINSR* have been updated to account for the new ReadInt2Fpu. That read is mapped to the the GPR input operand. On Jaguar, int-to-fpu transfers are modeled as a +6cy delay. Before this patch, that extra delay was added to the opcode latency. In practice, the insert opcode only executes for 1cy. Most of the actual latency is actually contributed by the so-called operand-latency. According to the AMD SOG for family 16h, (V)PINSR* latency is defined by expression f+1, where f is defined as a forwarding delay from the integer unit to the fpu. When printing instruction latency from MCA (see InstructionInfoView.cpp) and LLC (only when flag -print-schedule is speified), we now need to account for any extra forwarding delays. We do this by checking if scheduling classes declare any negative ReadAdvance entries. Quoting a code comment in TargetSchedule.td: "A negative advance effectively increases latency, which may be used for cross-domain stalls". When computing the instruction latency for the purpose of our scheduling tests, we now add any extra delay to the formula. This avoids regressing existing codegen and mca schedule tests. It comes with the cost of an extra (but very simple) hook in MCSchedModel. Differential Revision: https://reviews.llvm.org/D57056 llvm-svn: 351965
