/* An exception is an event that can be signaled from within a
|
|
|
|
|
|
function. This event can then be "caught" or "trapped" by the
|
|
|
|
|
|
callers of this function. This potentially allows program flow to
|
1997-12-06 17:31:01 -07:00
|
|
|
|
be transferred to any arbitrary code associated with a function call
|
1996-09-14 20:47:01 -04:00
|
|
|
|
several levels up the stack.
|
|
|
|
|
|
|
|
|
|
|
|
The intended use for this mechanism is for signaling "exceptional
|
|
|
|
|
|
events" in an out-of-band fashion, hence its name. The C++ language
|
|
|
|
|
|
(and many other OO-styled or functional languages) practically
|
|
|
|
|
|
requires such a mechanism, as otherwise it becomes very difficult
|
|
|
|
|
|
or even impossible to signal failure conditions in complex
|
|
|
|
|
|
situations. The traditional C++ example is when an error occurs in
|
|
|
|
|
|
the process of constructing an object; without such a mechanism, it
|
|
|
|
|
|
is impossible to signal that the error occurs without adding global
|
|
|
|
|
|
state variables and error checks around every object construction.
|
|
|
|
|
|
|
|
|
|
|
|
The act of causing this event to occur is referred to as "throwing
|
|
|
|
|
|
an exception". (Alternate terms include "raising an exception" or
|
|
|
|
|
|
"signaling an exception".) The term "throw" is used because control
|
|
|
|
|
|
is returned to the callers of the function that is signaling the
|
|
|
|
|
|
exception, and thus there is the concept of "throwing" the
|
|
|
|
|
|
exception up the call stack.

1999-08-25 22:10 -0700 Zack Weinberg <zack@bitmover.com>
* system.h: Don't redefine abort or trim_filename.
* rtl.h: Define abort to fancy_abort (__FILE__, __LINE__, 0)
or fancy_abort (__FILE__, __LINE__, __FUNCTION__) depending on
whether or not __FUNCTION__ is available.
* tree.h: Duplicate rtl.h's definition of abort, for files
that don't include rtl.h. Delete all code to perform type
checking with a compiler other than GCC.
* varray.h: Delete all code to perform type checking with a
compiler other than GCC. Make VARRAY_CHECK() always evaluate
its arguments exactly once, using a statement expression.
Adjust the VARRAY_<type> accessor macros to match.
* toplev.h (fatal_insn, fatal_insn_not_found): Kill.
(_fatal_insn, _fatal_insn_not_found): New fns, take info on
caller's location. Define fatal_insn and fatal_insn_not_found
as macros that use _fatal_insn and _fatal_insn_not_found.
(fancy_abort, trim_filename): Kill prototypes.
* rtl.c (trim_filename): Move here from toplev.c.
(fancy_abort): New function.
(DIR_SEPARATOR): Provide default definition.
* tree.c (tree_check_failed, tree_class_check_failed): Go
through fancy_abort.
(tree_check, tree_class_check, cst_or_constructor_check,
expr_check): Delete.
* varray.c (varray_check_failed): New function.
* toplev.c (fatal_insn, fatal_insn_not_found): Replace with
_fatal_insn and _fatal_insn_not_found. Go through
fancy_abort.
(trim_filename, fancy_abort): Delete.
* builtins.c (expand_builtin_args_info): Report ICE with abort.
* except.c (start_catch_handler): Report ICE with error/abort
combo.
* final.c (output_operand_lossage): Likewise.
* flow.c (verify_flow_info): Likewise.
* gcc.c: Prototype fatal.
* gengenrtl.c: Undef abort after including rtl.h not system.h.
* genattr.c, genattrtab.c, genemit.c, genextract.c,
genflags.c, genopinit.c, genoutput.c, genpeep.c, genrecog.c:
Don't define fancy_abort.
