From 67f3791f7d133214b112bd831ff2876822c665d0 Mon Sep 17 00:00:00 2001 From: Jan Hubicka Date: Fri, 23 Oct 2020 21:44:23 +0200 Subject: Move thunks out of cgraph_node this patch moves thunk_info out of cgraph_node into a symbol summary. I also moved it to separate hearder file since cgraph.h became really too fat. I plan to contiue with similar breakup in order to cleanup interfaces and reduce WPA memory footprint (symbol table now consumes more memory than trees) gcc/ChangeLog: 2020-10-23 Jan Hubicka * Makefile.in: Add symtab-thunks.o (GTFILES): Add symtab-thunks.h and symtab-thunks.cc; remove cgraphunit.c * cgraph.c: Include symtab-thunks.h.
