* Give backtraces for diagnostics from macros and include files.Tavian Barnes2010-04-189-27/+66
| | | | | Partly this means that dmnsn_diagnostic() can't be called anywhere except during parsing, because the dmnsn_parse_location::parent pointers dangle.
* Plug memory leak in object parsing failure path.Tavian Barnes2010-04-181-42/+45
|
* Have dmnsn_diagnostic() take a dmnsn_parse_location.Tavian Barnes2010-04-1812-156/+103
|
* Support objects in object{} blocks.Tavian Barnes2010-04-181-0/+22
|
* Support all object identifier types.Tavian Barnes2010-04-181-1/+6
|
* Fix segfault on parse error within macro.Tavian Barnes2010-04-181-1/+2
| | | | | The macro token buffer was being freed by both yylex_cleanup() and dmnsn_delete_patricia_trie().
* Rename dmnsn_matrix_*_mul() to dmnsn_transform_*().Tavian Barnes2010-04-1714-68/+68

|
* Don't use dynamic memory for dmnsn_intersection's.Tavian Barnes2010-04-079-242/+231

|
* New dmnsn_malloc() function, and friends.Tavian Barnes2010-04-0741-959/+438
| | | | | | I'm tired of checking for malloc failures everywhere, considering it never happens. So just bail out whenever it does. A lot of stuff is guaranteed to succeed if it returns now.
