Subject: [PATCH 00/26] Allow multiple "partial" symtab readers per objfile
Date: Sun, 28 Feb 2021 13:37:37 -0700 [thread overview]
Message-ID: <20210228203803.1693413-1-tom@tromey.com> (raw)
Right now, gdb attaches partial symtabs to each objfile, whether the
objfile needs them or not. Furthermore, multiple symbol readers can
create partial symbols, and they must all share the same storage.
This latter restriction affects the DWARF reader -- it can't share
psymtabs if some other reader has created them.
This series lifts these restrictions. At the end, an objfile can have
any number of "partial symbol" (really the so-called "quick"
functions) readers, even zero. Each reader is separate, and so the
restrictions on sharing of DWARF partial symbols are lifted.
I used my script to regression test each patch here on x86-64 Fedora 32.
Tom
