Add uniform debug dump function names.
Add some overloaded functions that provide uniform debug dump
function names. These names are:
debug: the general debug dumper
debug_verbose: for more details
debug_raw: for the gory details
debug_head: for the heads of declarations, e.g. function heads
debug_body: for the bodies of declarations, e.g. function bodies
Not all types have the last four versions.
The debug functions come in two flavors, those that take pointers
to the type, and those that take references to the type. The first
handles printing of '<nil>' for null pointers. The second assumes
a valid reference, and prints the content.
Example uses are as follows:
cp_token t, *p;
debug (t);
debug (p);
From the debugger, use
call debug (t)
The functions sets implemented are:
debug (only)
basic_block_def, const bitmap_head_def, cp_binding_level,
cp_parser, cp_token, data_reference, die_struct, edge_def,
gimple_statement_d, ira_allocno, ira_allocno_copy, live_range,
lra_live_range, omega_pb_d, pt_solution, const rtx_def, sreal,
tree_live_info_d, _var_map,
vec<cp_token, va_gc>, vec<data_reference_p>, vec<ddr_p>,
vec<rtx>, vec<tree, va_gc>,
debug and debug_raw
simple_bitmap_def
debug and debug_verbose
expr_def, struct loop, vinsn_def
debug, debug_raw, debug_verbose, debug_head, debug_body
const tree_node
This patch is somewhat different from the original plan at
gcc.gnu.org/wiki/cxx-conversion/debugging-dumps. The reason
is that gdb has an incomplete implementation of C++ call syntax;
requiring explicit specification of template arguments and explicit
specification of function arguments even when they have default
values. So, the original plan would have required typing
call dump <cp_token> (t, 0, 0, stderr)
which is undesireable. Instead instead of templates, we overload
plain functions. This adds a small burden of manually adding
the pointer version of dump for each type. Instead of default
function arguments, we simply assume the default values. Most of
the underlying dump functions did not use the options and indent
parameters anyway. Several provide FILE* parameters, but we expect
debugging to use stderr anyway. So, the explicit specification of
arguments was not as valuable as we thought initially. Finally,
a change of name from dump to debug reflect the implicit output
to stderr.

This patch rewrites the old VEC macro-based interface into a new one based on the template class 'vec'.
This patch rewrites the old VEC macro-based interface into a new one
based on the template class 'vec'. The user-visible changes are
described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec.
I have tested the patch pretty extensively:
- Regular bootstraps on x86_64, ppc, ia64, sparc and hppa.
- Bootstraps with --enable-checking=release
- Bootstraps with --enable-checking=gc,gcac
- Basic builds on all targets (using contrib/config-list.mk).
We no longer access the vectors via VEC_* macros. The pattern is
"VEC_operation (T, A, V, args)" becomes "V.operation (args)".
The only thing I could not do is create proper ctors and dtors for the
vec class. Since these vectors are stored in unions, we
have to keep them as PODs (C++03 does not allow non-PODs in unions).
This means that creation and destruction must be explicit. There is a
new method vec<type, allocation, layout>::create() and another vec<type,
allocation, layout>::destroy() to allocate the internal vector.
For vectors that must be pointers, there is a family of free functions
that implement the operations that need to tolerate NULL vectors.
These functions all start with the prefix 'vec_safe_'. See the wiki
page for details.
The gengtype change removes the special handling for VEC() that used
to exist in gengtype. Additionally, it allows gengtype to recognize
templates of more than one argument and introduces the concept of an
undefined type (useful for template arguments that may or may not be
types).
When a TYPE_UNDEFINED is reached, gengtype will ignore it if it
happens inside a type marked with GTY((user)). Otherwise, it will
emit an error.
Finally, gengtype rejects root types marked GTY((user)) that are not
first class pointers.

This patch rewrites the old VEC macro-based interface into a new one based on the template class 'vec'.
This patch rewrites the old VEC macro-based interface into a new one
based on the template class 'vec'. The user-visible changes are
described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec.
I have tested the patch pretty extensively:
- Regular bootstraps on x86_64, ppc, ia64, sparc and hppa.
- Bootstraps with --enable-checking=release
- Bootstraps with --enable-checking=gc,gcac
- Basic builds on all targets (using contrib/config-list.mk).
We no longer access the vectors via VEC_* macros. The pattern is
"VEC_operation (T, A, V, args)" becomes "V.operation (args)".
The only thing I could not do is create proper ctors and dtors for the
vec class. Since these vectors are stored in unions, we
have to keep them as PODs (C++03 does not allow non-PODs in unions).
This means that creation and destruction must be explicit. There is a
new method vec<type, allocation, layout>::create() and another vec<type,
allocation, layout>::destroy() to allocate the internal vector.
For vectors that must be pointers, there is a family of free functions
that implement the operations that need to tolerate NULL vectors.
These functions all start with the prefix 'vec_safe_'. See the wiki
page for details.
The gengtype change removes the special handling for VEC() that used
to exist in gengtype. Additionally, it allows gengtype to recognize
templates of more than one argument and introduces the concept of an
undefined type (useful for template arguments that may or may not be
types).
When a TYPE_UNDEFINED is reached, gengtype will ignore it if it
happens inside a type marked with GTY((user)). Otherwise, it will
emit an error.
Finally, gengtype rejects root types marked GTY((user)) that are not
first class pointers.

This patch rewrites the old VEC macro-based interface into a new one based on the template class 'vec'.
This patch rewrites the old VEC macro-based interface into a new one
based on the template class 'vec'. The user-visible changes are
described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec.
I have tested the patch pretty extensively:
- Regular bootstraps on x86_64, ppc, ia64, sparc and hppa.
- Bootstraps with --enable-checking=release
- Bootstraps with --enable-checking=gc,gcac
- Basic builds on all targets (using contrib/config-list.mk).
We no longer access the vectors via VEC_* macros. The pattern is
"VEC_operation (T, A, V, args)" becomes "V.operation (args)".
The only thing I could not do is create proper ctors and dtors for the
vec class. Since these vectors are stored in unions, we
have to keep them as PODs (C++03 does not allow non-PODs in unions).
This means that creation and destruction must be explicit. There is a
new method vec<type, allocation, layout>::create() and another vec<type,
allocation, layout>::destroy() to allocate the internal vector.
For vectors that must be pointers, there is a family of free functions
that implement the operations that need to tolerate NULL vectors.
These functions all start with the prefix 'vec_safe_'. See the wiki
page for details.
The gengtype change removes the special handling for VEC() that used
to exist in gengtype. Additionally, it allows gengtype to recognize
templates of more than one argument and introduces the concept of an
undefined type (useful for template arguments that may or may not be
types).
When a TYPE_UNDEFINED is reached, gengtype will ignore it if it
happens inside a type marked with GTY((user)). Otherwise, it will
emit an error.
Finally, gengtype rejects root types marked GTY((user)) that are not
first class pointers.

If UPDATE_DOMINANCE is true then this function updates dominators locally
|
|
|
|
(LOOPS structure that contains the information about dominators is passed
|
|
|
|
to enable this), otherwise it does not update the dominator information
|
|
|
|
and it assumed that the caller will do this, perhaps by destroying and
|
|
|
|
recreating it instead of trying to do an incremental update like this
|
|
|
|
function does when update_dominance is true.
