2012-11-17This patch rewrites the old VEC macro-based interface into a new one based ↵Diego Novillo1-23/+21
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 Novillo1-1/+1
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 *'.

2012-04-30Fix -Wuninitialized for -ftrack-macro-expansionDodji Seketeli1-4/+11
Besides the warning emitted by warn_uninit, this function wants to hint the user at where the uninitialized variable was declared, for cases where the declaration location is outside the current function. Now that expand_location expands to the location that is in the main source file (even for -ftrack-macro-expansion) the hinting part was not working well for cases where the variable is declared in a macro (outside the function), which is then expanded in the function. So I had to adjust warn_uninit a little bit to make it consider the spelling location of the variable declaration. I have fixed the test gcc.dg/cpp/pragma-diagnostic-2.c on which I believe gcc shouldn't emit any error. Here is the new output on that test: =~= gcc.dg/cpp/pragma-diagnostic-2.c: In function 'g': gcc.dg/cpp/pragma-diagnostic-2.c:10:5: warning: 'a' is used uninitialized in this function [-Wuninitialized] gcc.dg/cpp/pragma-diagnostic-2.c:9:7: note: 'a' was declared here gcc.dg/cpp/pragma-diagnostic-2.c:9:7: note: in expansion of macro 'CODE_WITH_WARNING' gcc.dg/cpp/pragma-diagnostic-2.c:17:3: note: expanded from here gcc.dg/cpp/pragma-diagnostic-2.c: In function 'h': gcc.dg/cpp/pragma-diagnostic-2.c:10:5: warning: 'a' is used uninitialized in this function [-Wuninitialized] gcc.dg/cpp/pragma-diagnostic-2.c:9:7: note: 'a' was declared here gcc.dg/cpp/pragma-diagnostic-2.c:9:7: note: in expansion of macro 'CODE_WITH_WARNING' gcc.dg/cpp/pragma-diagnostic-2.c:27:3: note: expanded from here =~= Tested and bootstrapped on x86_64-unknown-linux-gnu against trunk.
