The + values to be restored were being gotten in the inferior frame, and + the restoring was done in the superior frame. This means that i + registers must be restored into o registers. + + * sparc-dep.c (do_restore_insn): Modified to take a pc as an + argument, instead of a raw_buffer.

It's getting + the information associated with a given frame (ie. saved + registers) that's a bitch, because that stuff is saved relative to + the stack pointer rather than the frame pointer. + + * m-sparc.h (GET_PREV_FRAME_FROM_CACHE_ITEM): Modified to return + the frame pointer of the previous frame instead of the stack + pointer of same. + + * blockframe.c (flush_cached_frames): Modified call to + obstack_free to free back to frame_cache instead of back to zero. + This leaves the obstack control structure in finite state (and + still frees the entry allocated at frame_cache). + +Sat Oct 15 16:30:47 1988 & Smith (randy at tartarus.uchicago.edu) + + * valops.c (call_function): Suicide material here.

Oops. + + * dbxread.c (process_symbol_for_psymtab): Put every debugger + symbol which survives the top case except for constants on the + symchain. This means that all of these *won't* show up in misc + functions (this will be fixed once I make sure it's broken the way + it's supposed to be). + + * dbxread.c: Modified placement of debugger globals onto the hash + list; now we exclude the stuff after the colon and don't skip the + first character (debugger symbols don't have underscores). + + * dbxread.c: Killed debuginfo stuff with ifdef's. + +Wed Sep 28 14:31:51 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu) + + * symtab.h, dbxread.c: Modified to deal with BINCL, EINCL, and + EXCL symbols produced by the sun loader by adding a list of + pre-requisite partial_symtabs that each partial symtab needs. + + * symtab.h, dbxread.c, symtab.c, symmisc.c: Modified to avoid + doing a qsort on the local (static) psymbols for each file to + speed startup.
