per-function subtarget. Currently, code-gen passes the default or generic subtarget to the constructors of MCInstPrinter subclasses (see LLVMTargetMachine::addPassesToEmitFile), which enables some targets (AArch64, ARM, and X86) to change their instprinter's behavior based on the subtarget feature bits. Since the backend can now use different subtargets for each function, instprinter has to be changed to use the per-function subtarget rather than the default subtarget. This patch takes the first step towards enabling instprinter to change its behavior based on the per-function subtarget. It adds a bit "PassSubtarget" to AsmWriter which tells table-gen to pass a reference to MCSubtargetInfo to the various print methods table-gen auto-generates. I will follow up with changes to instprinters of AArch64, ARM, and X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233411 91177308-0d34-0410-b5e6-96231b3b80d8
