From e82e4eb5e9b3db07789a999a88a1b7909fd2dd45 Mon Sep 17 00:00:00 2001 From: dnovillo Date: Tue, 11 Sep 2012 00:04:13 +0000 Subject: Remove unnecessary VEC function overloads. 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 * 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 &'. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@191165 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-switch-conversion.c | 19 ++++++++----------- 1 file changed, 8 insertions(+), 11 deletions(-) (limited to 'gcc/tree-switch-conversion.c') diff --git a/gcc/tree-switch-conversion.c b/gcc/tree-switch-conversion.c index bb89d30fc32..bbbd3caca02 100644 --- a/gcc/tree-switch-conversion.c +++ b/gcc/tree-switch-conversion.c @@ -868,13 +868,11 @@ build_constructors (gimple swtch, struct switch_conv_info *info) int k; for (k = 0; k < info->phi_count; k++) { - constructor_elt *elt; + constructor_elt elt; - elt = VEC_quick_push (constructor_elt, - info->constructors[k], NULL); - elt->index = int_const_binop (MINUS_EXPR, pos, - info->range_min); - elt->value = info->default_values[k]; + elt.index = int_const_binop (MINUS_EXPR, pos, info->range_min); + elt.value = info->default_values[k]; + VEC_quick_push (constructor_elt, info->constructors[k], elt); } pos = int_const_binop (PLUS_EXPR, pos, integer_one_node); @@ -896,12 +894,11 @@ build_constructors (gimple swtch, struct switch_conv_info *info) do { - constructor_elt *elt; + constructor_elt elt; - elt = VEC_quick_push (constructor_elt, - info->constructors[j], NULL); - elt->index = int_const_binop (MINUS_EXPR, pos, info->range_min); - elt->value = val; + elt.index = int_const_binop (MINUS_EXPR, pos, info->range_min); + elt.value = val; + VEC_quick_push (constructor_elt, info->constructors[j], elt); pos = int_const_binop (PLUS_EXPR, pos, integer_one_node); } while (!tree_int_cst_lt (high, pos) -- cgit v1.2.1
