* rbtree: add rb_search_exact()HEADmasterH. Peter Anvin (Intel)2020-07-082-0/+13
| | | | | | | | Sometimes we want to search for an exact key only, and reject the case when tree->key < key. Add rb_search_exact() for this purpose, rather than forcing the caller to perform the comparison in open code. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
* rbtree: implement rb_first(), rb_last() operationsH. Peter Anvin (Intel)2020-07-082-11/+48
| | | | | | | | | | | | | | | | | | Add operations to get the first and last entry in the tree, respectively. Searching for 0 or ~UINT64_C(0) is not sufficient in the presence of duplicated keys, and is more inefficient anyway. rb_first() followed by rb_next() until NULL, or equivalently rb_last() followed by rb_prev() until NULL, can be used to walk the tree in key order (ascending or descending), including all duplicate key entries. Since this is a *threaded* tree now, this walk can safely free entires as it goes along, as long as the whole tree is destroyed; once any one entry has been freed, the tree is no longer valid for anything other than proceeding with the same tree walk.

| * preproc: handle %+ pasting after empty expansionsH. Peter Anvin (Intel)2020-07-051-20/+16
| | | | | | | | | | | | | | | | | | %+ tokens can end up next to each other, or at the beginning or the end of an expansion if we try to paste the output of empty macros. This is perhaps particularly likely to happen in %[] expressions. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
| * Make debug info and error messages correctly reflect macros and repsH. Peter Anvin (Intel)2020-07-057-164/+260
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Error messages would issue with the line number of %endrep. 2. Debug line information would ignore both macros and reps. This is doubly wrong; macros are semantically equivalent to inline functions, and it is expected that debuggers trace into these functions. These changes finishes the last parts of moving all responsibility for the listing enable/disable into the preprocessor, so remove the way over-complicated macro inhibit facility from the listing module entirely.

| * clang: mark inline functions unused and add warning optionsH. Peter Anvin (Intel)2020-06-306-22/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | clang, unlike gcc, will warn on inline functions which are unused. This can happen if a function is either intended to be used in the future, or it is only used under certain config options. Mark those functions with the "unused" attribute; not only does it quiet the warning, but it also documents it for the user. Shuffle around the warning options in configure and add a few more that are specific to clang. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
| * BR 3392687: clang miscompiles offsetin() for uninitialized pointerH. Peter Anvin (Intel)2020-06-301-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The actual pointer value in offsetin() cancels out, but clang still miscompiles offsetin() for an uninitialized pointer, considering the value to be completely undefined. Initialize pointer being passed to offsetin() to make clang happy; both the gcc and clang optimizers discover later in the code that the initialization is unused and removes it from the code. Although technically undefined behavior, this is in my opinion a severe quality of implementation bug in clang, and I will file a bug report accordingly.

* | rbtree: implement a "threaded LLRB tree"H. Peter Anvin (Intel)2020-06-292-57/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the left-leaning red-black (LLRB) trees into left-leaning threaded red-black trees. Instead of NULL pointers at leaf nodes, use the otherwise unused field as a pointer to the lexical predecessor (left) or successor (right). This allows fast previous/next interator operation without needing to keep track of the root of the tree at all times. The additional metadata that needs to be kept can be done for "free" simply by changing "bool red" into a flag field. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Pretty much all the backends have to do the same gymnastics to handle symbols and sections. In the future, this should be done by the assembly core, but in order to prepare the ground and get the performance benefits as soon as possible, implement a library of functions which can manage symbols and sections and their respective hashes, trees, and tables. This infrastructure is not yet used by any backend, that porting work has to come next. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
