cp-tree.h: Use __FUNCTION__ not __PRETTY_FUNCTION__.

[thirdparty/gcc.git] / gcc / cp / ChangeLog

2000-07-20  Zack Weinberg  <zack@wolery.cumb.org>

        * cp-tree.h: Use __FUNCTION__ not __PRETTY_FUNCTION__.
        Define my_friendly_assert and my_friendly_abort as macros
        which may call friendly_abort.  Prototype friendly abort, not
        my_friendly_abort or my_friendly_assert.
        * decl.c (signal_catch): Report the signal caught in the error
        message.  Call fatal directly.
        * typeck2.c (ack, my_friendly_assert): Delete.
        (my_friendly_abort): Rename to friendly_abort.  Expect file,
        line, and function parameters.  Report the abort code, then
        call fancy_abort.  Do not mask an abort if errors have
        already occurred.
