-/*
- * 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.

/* 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.
