New glibc with profiling fixed.

pa'ers,

glibc 2.3.2.ds1-10

- Added profiling patches (Thanks Randolph!)
- Rebuilt glibc.
- Did not modify changelog or bump version.

Testers wanted please, in particular to test if building with -pg works on your system and you get the expected results.

If testing goes well, these patches are going into debian-glibc's tree.

Cheers,
Carlos.

Oh yeah...

I finally installed these (libc6 and libc6-dev) and live is still good. thanks carlos!

Excellent. You haven't tried profiling any programs have you? :) Compile with CFLAGS=-pg, run-em, then run gprof on the gmon.out output?

Profiing? what's that? :^P

ok...I'll try tonight.

Here's "apps/openssl speed rsa" gprof output from my c3000. (2.6.0-pa7, Debian testing)

TBH, it looks wrong.
I didn't expect "get_dsa1024" to show up.
I suspect I didn't get all the various CFLAGS.
I edited */Makefile and added -pg by hand to "CFLAG" variables and then "make clean" + "make".

-----------------------------------------------

This table describes the call tree of the program, and was sorted by the total amount of time spent in each function and its children.

Each entry in this table consists of several lines. The line with the index number at the left hand margin lists the current function. The lines above it list the functions that called this function, and the lines below it list the functions this one called. This line lists:
index A unique number given to each element of the table.
Index numbers are sorted numerically.
The index number is printed next to every function name so it is easier to look up where the function in the table.

% time This is the percentage of the `total' time that was spent
in this function and its children. Note that due to different viewpoints, functions excluded by options, etc, these numbers will NOT add up to 100%.

self This is the total amount of time spent in this function.

children This is the total amount of time propagated into this
function by its children.

called This is the number of times the function was called.
If the function called itself recursively, the number only includes non-recursive calls, and is followed by a `+' and the number of recursive calls.

name The name of the current function. The index number is
printed after it. If the function is a member of a cycle, the cycle number is printed between the function's name and the index number.

For the function's parents, the fields have the following meanings:

self This is the amount of time that was propagated directly
from the function into this parent.

children This is the amount of time that was propagated from
the function's children into this parent.

called This is the number of times this parent called the
function /' the total number of times the function was called. Recursive calls to the function are not included in the number after the /'.

name This is the name of the parent. The parent's index
number is printed after it. If the parent is a member of a cycle, the cycle number is printed between the name and the index number.

If the parents of the function cannot be determined, the word <spontaneous>' is printed in the name' field, and all the other fields are blank.

For the function's children, the fields have the following meanings:

self This is the amount of time that was propagated directly
from the child into the function.

children This is the amount of time that was propagated from the
child's children to the function.

called This is the number of times the function called
this child /' the total number of times the child was called. Recursive calls by the child are not listed in the number after the /'.

name This is the name of the child. The child's index
number is printed after it. If the child is a member of a cycle, the cycle number is printed between the name and the index number.

If there are any cycles (circles) in the call graph, there is an entry for the cycle-as-a-whole. This entry shows who called the cycle (as parents) and the members of the cycle (as children.) The `+' recursive calls entry shows the number of function calls that were internal to the cycle, and the calls entry for each member shows, for that member, how many times it was called from other members of the cycle.

-----------------------------------------------

This table describes the call tree of the program, and was sorted by the total amount of time spent in each function and its children.

Each entry in this table consists of several lines. The line with the index number at the left hand margin lists the current function. The lines above it list the functions that called this function, and the lines below it list the functions this one called. This line lists:
index A unique number given to each element of the table.
Index numbers are sorted numerically.
The index number is printed next to every function name so it is easier to look up where the function in the table.

% time This is the percentage of the `total' time that was spent
in this function and its children. Note that due to different viewpoints, functions excluded by options, etc, these numbers will NOT add up to 100%.

self This is the total amount of time spent in this function.

children This is the total amount of time propagated into this
function by its children.

called This is the number of times the function was called.
If the function called itself recursively, the number only includes non-recursive calls, and is followed by a `+' and the number of recursive calls.

name The name of the current function. The index number is
printed after it. If the function is a member of a cycle, the cycle number is printed between the function's name and the index number.

For the function's parents, the fields have the following meanings:

self This is the amount of time that was propagated directly
from the function into this parent.

children This is the amount of time that was propagated from
the function's children into this parent.

called This is the number of times this parent called the
function /' the total number of times the function was called. Recursive calls to the function are not included in the number after the /'.

name This is the name of the parent. The parent's index
number is printed after it. If the parent is a member of a cycle, the cycle number is printed between the name and the index number.

If the parents of the function cannot be determined, the word <spontaneous>' is printed in the name' field, and all the other fields are blank.

For the function's children, the fields have the following meanings:

self This is the amount of time that was propagated directly
from the child into the function.

children This is the amount of time that was propagated from the
child's children to the function.

called This is the number of times the function called
this child /' the total number of times the child was called. Recursive calls by the child are not listed in the number after the /'.

name This is the name of the child. The child's index
number is printed after it. If the child is a member of a cycle, the cycle number is printed between the name and the index number.

If there are any cycles (circles) in the call graph, there is an entry for the cycle-as-a-whole. This entry shows who called the cycle (as parents) and the members of the cycle (as children.) The `+' recursive calls entry shows the number of function calls that were internal to the cycle, and the calls entry for each member shows, for that member, how many times it was called from other members of the cycle.

Hi Carlos,

btw may I ask your patch so that I can test it in my tc process (and why not trying profiling on kernel build ;) )

Thanks in advance,
Joel

Excellent. You haven't tried profiling any programs have you? :) Compile with CFLAGS=-pg, run-em, then run gprof on the gmon.out output?

How much testing has this had?
I'm willing to try it on various boxes if I have an idea of the risk involved.

thanks,
grant

Passes all the testsuites without regressions. Doesn't kill *my* system. It's a *minor* change to the existing glibc provided by debian, purely to fix the FTBS that lamont saw for "roy."

The GCC profiling tests still segfault. It looks like crtn.o hasn't been updated. Did I miss something?
