From: Simon Marchi Date: Mon, 9 Jun 2025 16:09:00 +0000 (-0400) Subject: gdb/amd-dbgapi: pass amd_dbgapi_inferior_info to process_one_event X-Git-Tag: binutils-2_45~298 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=606e490b9fddfb03282c7d04013b9b84109e2641;p=thirdparty%2Fbinutils-gdb.git gdb/amd-dbgapi: pass amd_dbgapi_inferior_info to process_one_event Pass the amd_dbgapi_inferior_info object from process_event_queue to process_one_event. Since process_event_queue pulls events for one specific inferior, we know for which inferior the event is. This removes the need for process_one_event to do two dbgapi calls to get the relevant pid. If also removes one inferior lookup.
