- - add support for prof file format so that prof files can be displayed
- at the line-level (this is useful for the uprofile tool under DEC's
- OSF/1)
- - take a hard look at --file-ordering (broken) and --function-ordering
- + documentation
- + optimize bfd_find_nearest_line_num() (or replace by different interface)
- + cleanup _bfd_ecoff_find_nearest_line_num() fixes & description
- + ensure "cc -pg" produces good files under OSF/1 v3.0
- + make sure gprof works together with OSF/1 v3.0's profiling libraries
- + implement symtab_parse(); modify sym_lookup() to consider addr_high
- + change gprof.c to collect lists, then invoke symtab_parse() for
- each list
- + Questions:
- o is -c (--static-call-graph) useful at all? i can't see
- how; if it were deleted, gprof would be completely machine
- independent => yup, it is
- o are (long) option names appropriate?
- o -k (--exclude-arc) cannot be implemented with getopt();
- is new syntax (-k from/to) acceptable? If not, how to
- fix it?
- o in the FSF output, the call-graph index now prints
- the filename of static functions in parentheses; e.g.,
- static function foo() that is defined in file bar.c
- would be printed as:
- [4] foo (bar.c)
- is this acceptable? should it be done only optionally?
- o symbols with addresses that map back to a different
- name are suppressed (happens with labels, for example);
- is this acceptable? should it be done only optionally?
- + generalize to allow arbitrary histograms (not just time histograms)
- + basic-block information currently replaces all symbols created from
- the core because of an ugly ordering conflict---for now, the current
- solution works, but something cleaner is desirable ==> cleaned up,
- but it's slower now
- + convert to very new file format (back to trivial format, that is :)
- + replace "dummy.h" for Alpha (if there is any use to it)
- + add support for execution time profiling at a basic-block level
- + fix filename-off-by-one bug for Alpha (see ~/tmp/d.[ch])---no longer
- relevant
- + "-pg -a" doesn't work as expected because mcleanup() will overwrite
- the file generated by __bb_exit_func() (or vice versa)
- + first basic-block of fac() seems to get credited to last basic-block
- of previous function => bug in basic_blocks.c
- + flat profile should provide automatic scaling for per-call times because
- otherwise they'll always be zero on a fast machine with tons of small
- functions
- + make "-a" imply to retain line number info (without actually generating
- the debugging information (unless -g is specified)---no, this is a
- bad idea, because it is not clear what level of debugging info should
- be requested (e.g., -g vs. -g3); leaving it up to the user seems best
- + add long options support (or at least use getopt instead of ad-hoc
- implementation)
- + split into files according to abstract objects that are manipulated
- + replace sccsid by rcsid & add "end of ..." to every .c file
- + use DBG() everywhere
- + fix spacing (" ," -> "," etc.)
- + use DEFUNs everywhere
- + make compile cleanly with -Wall
- + "gcc -pg -O2" doesn't work on tecc.c unless -fno-omit-frame-pointer is
- specified; find out why
- + make things portable (prototypes, const, etc.)
- + if NEW_GMON_OUT is not defined, have a flag that will allow to
- read new gmon.out style files. The idea being that everyone
- will use the new format for basic-block style profiling but
- the old format for regular gpprofiling
