Hi, If this is not the appropriate forum for reporting bugs concerning the gdb documentation, then I apologise; please let me know and I shall be happy to redirect this report. In the GDB Internals documentation, under section 8.7 Target Conditionals, the following macro description occurs: SIZEOF_CALL_DUMMY_WORDS The size of CALL_DUMMY_WORDS. When CALL_DUMMY_P this must return a positive value. See also CALL_DUMMY_LENGTH. However, the description of the CALL_DUMMY_LENGTH macro is missing. Also, in the same section there are a couple of sentences of the form "Should be deprecated in favor of something like STACK_ALIGN." (under CALL_DUMMY_STACK_ADJUST and CALL_DUMMY_STACK_ADJUST _P) as well as "Should be deprecated in favour of a macro that uses target-byte-ordered data." (under CALL_DUMMY_WORDS). Both examples give the impression of an unresolved issue. Is it intentionally left for the person implementing the port to resolve? The documentation is dated May 25 2000, so it doesn't seems like it should be outdated. Best regards, Orjan Friberg Axis Communications
