|
|---|
| 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
|
|---|
| 4 | OSF/1)
|
|---|
| 5 | - take a hard look at --file-ordering (broken) and --function-ordering
|
|---|
| 6 |
|
|---|
| 7 | + documentation
|
|---|
| 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
|
|---|
| 14 | each list
|
|---|
| 15 | + Questions:
|
|---|
| 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
|
|---|
| 22 | fix it?
|
|---|
| 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
|
|---|
| 26 | would be printed as:
|
|---|
| 27 |
|
|---|
| 28 | [4] foo (bar.c)
|
|---|
| 29 |
|
|---|
| 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,
|
|---|
| 38 | but it's slower now
|
|---|
| 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
|
|---|
| 43 | relevant
|
|---|
| 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
|
|---|
| 50 | functions
|
|---|
| 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
|
|---|
| 56 | implementation)
|
|---|
| 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
