- 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
