3 | * c-typeck.c (store_init_value): Don't require constant initializer | |
4 | elements with -pedantic -std=c99. | |
5 | (digest_init): Change error about non-constant initializer elements | |
6 | into pedwarn. | |
7 | (constructor_range_end): Remove. | |
8 | (constructor_incremental, designator_depth, | |
9 | designator_errorneous): New variables. | |
10 | (struct constructor_stack): Remove range_end, add incremental. | |
11 | (struct constructor_range_stack, constructor_range_stack): New. | |
12 | (struct initializer_stack): Add constructor_range_stack. | |
13 | (finish_init): Set it. | |
14 | (start_init): Likewise. require_constant_elements for non-static | |
15 | trees only if not flag_isoc99. | |
16 | (really_start_incremental_init): Remove constructor_range_end, add | |
17 | constructor_incremental. | |
18 | (pop_init_level): Likewise. | |
19 | (push_init_level): Likewise. If implicit and the subobject had some | |
20 | value set already, preinitialize the level with it. | |
21 | Warn about missing braces only if not pushing due to designators. | |
22 | (set_designator, push_range_stack): New functions. | |
23 | (set_init_label): Use them. | |
24 | (set_init_index): Likewise. Remove constructor_range_end. | |
25 | Error if designator index is outside of array bounds. | |

27 | trees themselves. Allow overwriting of already initialized element. | |
28 | Issue a warning if it had side-effects. | |

30 | functions. | |
31 | (pending_init_member): Rename to... | |
32 | (find_init_member): ...this function. Call set_nonincremental_init | |
33 | if necessary. Compare values of purpose index trees, not the trees | |
34 | themselves. Return the actual value, not just non-zero if something | |
35 | is found. | |
36 | (output_init_element): Remove checks for duplicates. | |
37 | If field has zero size, only check the initializer for correctness. | |
38 | Call set_nonincremental_init if necessary. Push RECORD/ARRAY into AVL | |
39 | if constructor_incremental is zero. Change error about initializers | |
40 | not computable at load time into pedwarn. | |
41 | (output_pending_init_elements): Compare bit positions, not | |
42 | FIELD_DECLs to take into account zero-sized fields. | |
43 | (process_init_element): Use constructor_range_stack to fill all | |
44 | ranges in the designator lists from current level up. | |
45 | * extend.texi: Update documentation for labeled elements. | |
