- 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
