Implement functions calls from within DDB on ia64. On ia64 a function pointer doesn't point to the first instruction of that function, but rather to a descriptor. The descriptor has the address of the first instruction, as well as the value of the global pointer. The symbol table doesn't know anything about descriptors, so if you lookup the name of a function you get the address of the first instruction. The cast from the address, which is the result of the symbol lookup, to a function pointer as is done in db_fncall is therefore invalid. Abstract this detail behind the DB_CALL macro. By default DB_CALL is defined as db_fncall_generic, which yields the old behaviour. On ia64 the macro is defined as db_fncall_ia64, in which a descriptor is constructed to yield a valid function pointer. While here, introduce DB_MAXARGS. DB_MAXARGS replaces the existing (local) MAXARGS. The DB_MAXARGS macro can be defined by platforms to create a convenient maximum. By default this will be the legacy 10. On ia64 we define this macro to be 8, for 8 is the maximum number of arguments that can be passed in registers. This avoids having to implement spilling of arguments on the memory stack.

Add a one-shot callout facility to db_printf() that executes the registered callout when a specified number of lines have been output. This can be used to implement pagers for ddb commands that output a lot of text. A simple paging function is included that automatically rearms itself when fired. Reviewed by: bde, julian

- Change the ddb paging "support" to use a variable (db_lines_per_page) to control the number of lines per page rather than a constant. The variable can be examined and changed in ddb as '$lines'. Setting the variable to 0 will effectively turn off paging. - Change db_putchar() to force out pending whitespace before outputting newlines and carriage returns so that one can rub out content on the current line via '\r \r' type strings. - Change the simple pager to rub out the --More-- prompt explicitly when the routine exits. - Add some aliases to the simple pager to make it more compatible with more(1): 'e' and 'j' do a single line. 'd' does half a page, and 'f' does a full page. MFC after: 1 month Inspired by: kris
