From: Tom Tromey Date: Tue, 22 Oct 2019 22:57:35 +0000 (-0600) Subject: Change allocate_psymtab to be a constructor X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=32caafd02b069c36908f41f53ae0cbca1911aaca;p=deliverable%2Fbinutils-gdb.git Change allocate_psymtab to be a constructor This is the next step in getting the symbol readers to allocate psymtabs themselves: change allocate_psymtab to be an ordinary constructor, and then use "new" at the previous call sites. Note that this doesn't get us all the way -- start_psymtab_common is still allocating a partial symtab. gdb/ChangeLog 2020-01-26 Tom Tromey * xcoffread.c (xcoff_end_psymtab): Use new. * psymtab.c (start_psymtab_common): Use new. (partial_symtab::partial_symtab): Rename from allocate_psymtab. Update. * psympriv.h (struct partial_symtab): Add parameters to constructor. Don't inline. (allocate_psymtab): Don't declare. * mdebugread.c (new_psymtab): Use new. * dwarf2read.c (dwarf2_create_include_psymtab): Use new. * dbxread.c (dbx_end_psymtab): Use new.
