2012-11-17This patch rewrites the old VEC macro-based interface into a new one based ↵Diego Novillo1-52/+56
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.

2012-10-31This patch implements generic type query and conversion functions,Lawrence Crowl1-1/+1
and applies them to the use of cgraph_node, varpool_node, and symtab_node. The functions are: bool is_a <TYPE> (pointer) Tests whether the pointer actually points to a more derived TYPE. TYPE *as_a <TYPE> (pointer) Converts pointer to a TYPE*. TYPE *dyn_cast <TYPE> (pointer) Converts pointer to TYPE* if and only if "is_a <TYPE> pointer". Otherwise, returns NULL. This function is essentially a checked down cast. These functions reduce compile time and increase type safety when treating a generic item as a more specific item. In essence, the code change is from if (symtab_function_p (node)) { struct cgraph_node *cnode = cgraph (node); .... } to if (cgraph_node *cnode = dyn_cast <cgraph_node> (node)) { .... } The necessary conditional test defines a variable that holds a known good pointer to the specific item and avoids subsequent conversion calls and the assertion checks that may come with them. When, the property test is embedded within a larger condition, the variable declaration gets pulled out of the condition. (This leaves some room for using the variable inappropriately.) if (symtab_variable_p (node) && varpool (node)->finalized) varpool_analyze_node (varpool (node)); becomes varpool_node *vnode = dyn_cast <varpool_node> (node); if (vnode && vnode->finalized) varpool_analyze_node (vnode); Note that we have converted two sets of assertions in the calls to varpool into safe and efficient use of a variable. There are remaining calls to symtab_function_p and symtab_variable_p that do not involve a pointer to a more specific type. These have been converted to calls to a functions is_a <cgraph_node> and is_a <varpool_node>. The original predicate functions have been removed. The cgraph.h header defined both a struct and a function with the name varpool_node. This name overloading can cause some unintuitive error messages when, as is common in C++, one omits the struct keyword when using the type. I have renamed the function to varpool_node_for_decl.

2012-09-10Remove unnecessary VEC function overloads.Diego Novillo1-7/+4
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 *'.

2012-08-14backport: As described in http://gcc.gnu.org/ml/gcc/2012-08/msg00015.html...Diego Novillo1-3/+3
Merge from cxx-conversion branch (http://gcc.gnu.org/wiki/cxx-conversion). As described in http://gcc.gnu.org/ml/gcc/2012-08/msg00015.html, this patch changes the default bootstrap process so that stage 1 always builds with a C++ compiler. Other than the bootstrap change, the patch makes no functional changes to the compiler. Everything should build as it does now in trunk. The main changes in this patch are: 1- Configuration changes. 2- Re-write of VEC. 3- Re-write of gengtype to support C++ templates and user-provided marking functions. 4- New hash table class. 5- Re-write double_int. 6- Implement tree macros as inline functions so they can be called from gdb. As discussed before, several of these changes do not fully change the call sites to use the new APIs. The bootstrap changes have already been tested on a wide range of targets (http://gcc.gnu.org/wiki/CppBuildStatus). Additionally, I have tested the merged trunk on: x86_64-unknown-linux-gnu, mips64el-unknown-linux-gnu, powerpc64-unknown-linux-gnu, i686-pc-linux-gnu, and ia64-unknown-linux-gnu.
