2013-03-29Add uniform debug dump function names.Lawrence Crowl1-0/+52
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.

2012-11-20Introduce vNULL to use as a nil initializer for vec<>.Diego Novillo1-3/+2

2012-11-17This patch rewrites the old VEC macro-based interface into a new one based ↵Diego Novillo1-194/+185
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. 2012-11-16 Diego Novillo <dnovillo@google.com> VEC API overhaul (http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec) * vec.c (register_overhead): Convert it into member function of vec_prefix.

2012-09-10Remove unnecessary VEC function overloads.Diego Novillo1-10/+10
Several VEC member functions that accept an element 'T' used to have two overloads: one taking 'T', the second taking 'T *'. This used to be needed because of the interface dichotomy between vectors of objects and vectors of pointers. In the past, vectors of pointers would use pass-by-value semantics, but vectors of objects would use pass-by-reference semantics. This is no longer necessary, but the distinction had remained. The main side-effect of this change is some code reduction in code that manipulates vectors of objects. For instance, - struct iterator_use *iuse; - - iuse = VEC_safe_push (iterator_use, heap, iterator_uses, NULL); - iuse->iterator = iterator; - iuse->ptr = ptr; + struct iterator_use iuse = {iterator, ptr}; + VEC_safe_push (iterator_use, heap, iterator_uses, iuse); Compile time performance was not affected. Tested on x86_64 and ppc64. Also built all-gcc on all targets using VEC routines: arm, bfin, c6x, epiphany, ia64, mips, sh, spu, and vms. 2012-09-10 Diego Novillo <dnovillo@google.com> * vec.h (vec_t::quick_push): Remove overload that accepts 'T *'. Update all users. (vec_t::safe_push): Likewise. (vec_t::quick_insert): Likewise. (vec_t::lower_bound): Likewise. (vec_t::safe_insert): Likewise. (vec_t::replace): Change second argument to 'T &'.
