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