NOTES
+Mon Mar 13 21:44:24 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
+
+ * __bb_exit_func.c: New file, from David Mosberger-Tang.
+
+ Thu Feb 9 16:56:07 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
+
+ * All *.c: More cleanup towards GNU format.
+
+ * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
+ replaced sizeof (bfd_vma) by size (char*) because Ken tells me
+ that bfd_vma is only guaranteed to be at least as big as a pointer.
+
+ (GMON_Record_tag): added explicit enumeration values to ensure
+ compatibility across compilers.
+
+ * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
+ sizeof(char*).
+
Tue Feb 7 17:24:12 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
* All *.c and *.h files: Ran "indent -gnu". Cleaned up a couple
-Sun Feb 5 16:27:32 1995
+Thu Feb 9 16:48:04 1995
- documentation
- optimize bfd_find_nearest_line_num() (or replace by different interface)
+- gmon_io.c cannot deal with target architecture that have a pointer size
+ that is different from the host architectures pointer size---fix this
+ (gmon_out.h, and gmon_io.c)
- add support for prof file format so that prof files can be displayed
at the line-level (this is useful for the uprofile tool under DEC's
OSF/1)
