Documentation of BlockExportRemoveMode has Potential additional modes to be added in the future: hide: Just hide export from new clients, leave existing connections as is. Remove export after all clients are disconnected. soft: Hide export from new clients, answer with ESHUTDOWN for all further requests from existing clients. I think this is useful only for developers. Elide it from generated documentation by turning it into a TODO section. This effectively reverts my own commit b71fd73cc45 (Revert "qapi: BlockExportRemoveMode: move comments to TODO"). At the time, I was about to elide TODO sections from the generated manual, I wasn't sure about this one, and decided to avoid change. And now I've made up my mind.

If an exception is to be raised, the destination fp register should be unmodified. The current implementation is incorrect, in that double results will be written back before calling gen_helper_check_ieee_exceptions, despite the placement of gen_store_fpr_D, since gen_dest_fpr_D returns cpu_fpr[]. We can simplify the entire implementation by having each FPOp helper call check_ieee_exceptions.

2024-02-03tcg/loongarch64: Set vector registers call clobberedRichard Henderson1-1/+1
Because there are more call clobbered registers than call saved registers, we begin with all registers as call clobbered and then reset those that are saved. This was missed when we introduced the LSX support.
