Currently "symtabs" in gdb are stored as a single linked list of struct symtab that contains both symbol symtabs (the blockvectors) and file symtabs (the linetables). This has led to confusion, bugs, and performance issues. This patch is conceptually very simple: split struct symtab into two pieces: one part containing things common across the entire compilation unit, and one part containing things specific to each source file. Example. For the case of a program built out of these files: foo.c foo1.h foo2.h bar.c foo1.h bar.h Today we have a single list of struct symtabs: objfile -> foo.c -> foo1.h -> foo2.h -> bar.c -> foo1.h -> bar.h -> NULL where "->" means the "next" pointer in struct symtab. With this patch, that turns into: objfile -> foo.c(cu) -> bar.c(cu) -> NULL | | v v foo.c bar.c | | v v foo1.h foo1.h | | v v foo2.h bar.h | | v v NULL NULL where "foo.c(cu)" and "bar.c(cu)" are struct compunit_symtab objects, and the files foo.c, etc. are struct symtab objects. So now, for example, when we want to iterate over all blockvectors we can now just iterate over the compunit_symtab list. Plus a lot of the data that was either unused or replicated for each symtab in a compilation unit now lives in struct compunit_symtab. E.g., the objfile pointer, the producer string, etc. I thought of moving "language" out of struct symtab but there is logic to try to compute the language based on previously seen files, and I think that's best left as is for now. With my standard monster benchmark with -readnow (which I can't actually do, but based on my calculations), whereas today the list requires 77MB to store all the struct symtabs, it now only requires 37MB. A modest space savings given the gigabytes needed for all the debug info, etc. Still, it's nice. Plus, whereas today we create a copy of dirname for each source file symtab in a compilation unit, we now only create one for the compunit. So this patch is basically just a data structure reorg, I don't expect significant performance improvements from it. Notes: 1) A followup patch can do a similar split for struct partial_symtab. I have left that until after I get the changes I want in to better utilize .gdb_index (it may affect how we do partial syms). 2) Another followup patch *could* rename struct symtab. The term "symtab" is ambiguous and has been a source of confusion. In this patch I'm leaving it alone, calling it the "historical" name of "filetabs", which is what they are now: just the file-name + line-table. gdb/ChangeLog: Split struct symtab into two: struct symtab and compunit_symtab. * amd64-tdep.c (amd64_skip_xmm_prologue): Fetch producer from compunit. * block.c (blockvector_for_pc_sect): Change "struct symtab *" argument to "struct compunit_symtab *".
