If it comes - out, congratulations. If not, then the variable Stack_check_Blown_task - contains a pointer to the TCB of the offending task. This - is usually enough to go on. - -FUTURE: - -1. Determine how/if gcc will generate stack probe calls and support that. - -2. Get accurate stack usage numbers on i960.. it pushes very large - holes on the stack. diff --git a/cpukit/libmisc/stackchk/check.c b/cpukit/libmisc/stackchk/check.c deleted file mode 100644 index 8b923f5c02..0000000000 --- a/cpukit/libmisc/stackchk/check.c +++ /dev/null @@ -1,439 +0,0 @@ -/* - * Stack Overflow Check User Extension Set - * - * NOTE: This extension set automatically determines at - * initialization time whether the stack for this - * CPU grows up or down and installs the correct - * extension routines for that direction. - * - * COPYRIGHT (c) 1989, 1990, 1991, 1992, 1993, 1994. - * On-Line Applications Research Corporation (OAR). - * All rights assigned to U.S. Government, 1994. - * - * This material may be reproduced by or for the U.S. Government pursuant - * to the copyright license under the clause at DFARS 252.227-7013.
