/*
* This is a modified gmon.c by J.W.Hawtin <oolon@ankh.org>,
* 14/8/96 based on the original gmon.c in GCC and the hacked version
* solaris 2 sparc version (config/sparc/gmon-sol.c) by Mark Eichin. To do
* process profiling on solaris 2.X X86
*
* It must be used in conjunction with sol2-gc1.asm, which is used to start
* and stop process monitoring.
*
* Differences.
*
* On Solaris 2 _mcount is called by library functions not mcount, so support
* has been added for both.
*
* Also the prototype for profil() is different
*
* Solaris 2 does not seem to have char *minbrk whcih allows the setting of
* the minimum SBRK region so this code has been removed and lets pray malloc
* does not mess it up.
*
* Notes
*
* This code could easily be integrated with the original gmon.c and perhaps
* should be.

* SUCH DAMAGE.
*/
/* FIXME: Check comment. */
/* Mangled into a form that works on SPARC Solaris 2 by Mark Eichin
* for Cygnus Support, July 1992.
*
* This is a modified gmon.c by J.W.Hawtin <oolon@ankh.org>,
* 14/8/96 based on the original gmon.c in GCC and the hacked version
* solaris 2 sparc version (config/sparc/gmon-sol.c) by Mark Eichin. To do
* process profiling on solaris 2.X X86
*
* It must be used in conjunction with sol2-gc1.asm, which is used to start
* and stop process monitoring.
*
* Differences.
*
* On Solaris 2 _mcount is called by library functions not mcount, so support
* has been added for both.
*
* Also the prototype for profil() is different
*
* Solaris 2 does not seem to have char *minbrk whcih allows the setting of
* the minimum SBRK region so this code has been removed and lets pray malloc
* does not mess it up.
*
* Notes
*
* This code could easily be integrated with the original gmon.c and perhaps
* should be.
