ryo | In order to prevent _mcount() from being recursively called when built with COPTS=-O0,
sprinkle `__always_inline' to make _mcount() be generated as a single function.
|
| 1.37 |
| 08-Jun-2017 |
christos | use compiler builtins to compute addresses instead %ebp assembly arithmetic.
(from joerg)
|
| 1.36 |
| 04-Jun-2017 |
christos | - prevent optimization from omitting the frame pointer (and re-using it);
we use it in our inline assembly.
- convert to c a little assembly to make the code more understandable.
|
| 1.35 |
| 31-May-2017 |
christos | branches: 1.35.2;
prevent coredumps by skipping everything early if we are not counting.
|
| 1.34 |
| 10-Jan-2016 |
ryo | __mcount_lock is moved to MI from MD.
because it is needed for all MULTIPROCESSOR arch, but it is exists only in i386 and amd64.
ok christos@, on tech-kern@
|
| 1.33 |
| 20-Dec-2007 |
ad | branches: 1.33.54; 1.33.74;
- Make __cpu_simple_lock and similar real functions and patch at runtime.
- Remove old x86 atomic ops.
- Drop text alignment back to 16 on i386 (really, this time).
- Minor cleanup.

garbled | branches: 1.32.4; 1.32.8;
Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

| 26-Sep-2007 |
ad | Inline interrupt disable for _mcount, so the real function calls don't
screw with profiling.
|
| 1.30 |
| 26-Sep-2007 |
ad | Make build in userspace again.
|
| 1.29 |
| 26-Sep-2007 |
xtraeme | Fix profiling kernels:
read_psl -> x86_read_psl
write_psl -> x86_write_psl
disable_intr -> x86_disable_intr

christos | branches: 1.28.2; 1.28.10; 1.28.12; 1.28.14;
As noted by uwe, we need to also save %edx because it can be used with
the regparm calling convention.
XXX: The c stub should be replaced with an assembly one.
|
| 1.27 |
| 16-Apr-2007 |
christos | save and restore %eax, %ecx, otherwise profiling does not work properly.
From Anon Ymous. Example program that fails:
int
main(int argc, char *argv[])
{
return argc;
}

Merge newlock2 to head.
|
| 1.25 |
| 16-Feb-2006 |
perry | branches: 1.25.14; 1.25.18;
Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.
As per core@.
|

| 24-Dec-2005 |
perry | branches: 1.24.2; 1.24.4; 1.24.6;
__asm__ -> __asm
__const__ -> const
__inline__ -> inline
__volatile__ -> volatile
|
| 1.23 |
| 24-Dec-2005 |
perry | Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.
|
| 1.22 |
| 02-Oct-2005 |
chs | put mcount.c in the normal object list, so that "make depend" works.
use a gcc attribute to prevent it from being instrumented.
|
| 1.21 |
| 25-Feb-2005 |
chs | branches: 1.21.4;
fix a typoe in previous.
|
| 1.20 |

chs | allow profiling of MP kernels, add a spinlock around the body of mcount().
|
| 1.19 |
| 24-May-2004 |
yamt | branches: 1.19.4; 1.19.6;
instead of blindly set IF in MCOUNT_EXIT,
save eflags in MCOUNT_ENTER and restore it.
|
| 1.18 |
| 27-Oct-2003 |
junyoung | Nuke __P().
|
| 1.17 |
| 07-Aug-2003 |
agc | Move UCB-licensed code from 4-clause to 3-clause licence.
Patches provided by Joel Baker in PR 22364, verified by myself.
|
| 1.16 |
| 30-Nov-2001 |
enami | branches: 1.16.2; 1.16.18;
Declare some asm statement with output as volatile. Without this,
gcc with -march=pentiumpro produce bad code.
|
| 1.15 |
| 23-Aug-2001 |
chs | use cli/sti instead of splhigh/splx for MCOUNT_ENTER/MCOUNT_EXIT.
this makes clearer how much time mcount() is really taking.
|

Delint.

enami | branches: 1.13.2;
Add missing backslash.
|
| 1.12 |
| 27-Sep-1999 |
kleink | For ELF, rename the profiling entry from mcount to __mcount to avoid clashing
with the user's namespace, also within file scope; for binary compatibility,
define a weak alias for the previous name to cover our tracks.
|
| 1.11 |
| 13-Nov-1998 |
christos | cast _mcount args to u_long, to avoid lint warnings.

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
