* User manual documentation for tunablesSiddhesh Poyarekar2016-12-311-1/+1
| | | | | | | | | Create a new node for tunables documentation and add notes for the malloc tunables. * manual/tunables.texi: New chapter. * manual/Makefile (chapters): Add it. * manual/probes.texi (@node): Point to the Tunables chapter.
* Manual typos: Internal probesRical Jasan2016-10-061-2/+2
| | | | | | 2016-05-06 Rical Jasan <ricaljasan@pacific.net> * manual/probes.texi: Fix typos in the manual.
* Fix two spaces after sentence.Ondřej Bílka2014-02-261-5/+5
| | | | | Minor formatting fix that was carried by issuing sed -e"s/\. \([A-Z]\)/. \1/" followed by editing result.

| | | | | | | | | | | | Use the term "triggered" instead of "hit" when talking about probe points. ChangeLog: 2014-02-11 Will Newton <will.newton@linaro.org> * manual/probes.texi (Mathematical Function Probes): Use "triggered" instead of "hit".
* manual/probes.texi: Add documentation of setjmp/longjmp probesWill Newton2014-02-111-0/+40
| | | | | | | | | | | | Add some documentation of the setjmp, longjmp and longjmp_target Systemtap probe points. ChangeLog: 2014-02-11 Will Newton <will.newton@linaro.org> * manual/probes.texi (Internal Probes): Add documentation of setjmp, longjmp and longjmp_target probes.

* Update documentation after dropping PER_THREAD conditional.Ondřej Bílka2013-12-181-34/+6
| | | | | In probes documentation we described what happens when PER_THREAD is disabled which is now not relevant.
* Consolidate valloc/pvalloc code.Ondřej Bílka2013-11-201-3/+2
| | | | | To make malloc code more maintainable we make malloc and pvalloc share logic with memalign.
* Add systemtap probe markers for sin, cos, asin and acosSiddhesh Poyarekar2013-11-201-0/+42

* Add systemtap markers to math function slow pathsSiddhesh Poyarekar2013-10-111-0/+98
| | | | | | | Add systemtap probes to various slow paths in libm so that application developers may use systemtap to find out if their applications are hitting these slow paths. We have added probes for pow, exp, log, tan, atan and atan2.
