This fixes a bug reported by Alex Renda on LLVMDev where mca did not correctly mark a resource group as "reserved". (See http://lists.llvm.org/pipermail/llvm-dev/2020-May/141485.html). The issue was caused by a wrong check in function `initializeUsedResources`. As a consequence of this, a resource group was left unreserved, and its field `NumUnits` incorrectly reported an unrealistic number of consumed resource units. This patch fixes the issue with the handling of reserved resources in the InstrBuilder class, and adds a simple test for it. Ideally, as suggested by Andy Trick, most of these problems will disappear if in the future we will introduce a (optional) DelayCycles vector for SchedWriteRes. |
