2019-12-08Fix overflows in -fprofile-reorder-functionsJan Hubicka7-59/+85
This patch fixes three sissues with -fprofile-reorder-functions: 1) First is that tp_first_run is stored as 32bit integer while it can easily overflow (and does so during Firefox profiling). 2) Second problem is that flag_profile_functions can not be tested w/o function context. The changes to expand_all_functions makes it to work on mixed units by first outputting all functions w/o -fprofile-reorder-function (or with no profile info) and then outputting in first_run order 3) LTO partitioner was mixing up order by tp_first_run and by order. for no_reorder we definitly want to order via first, while for everything else we want to roder by second. I have also merged duplicated comparators since they are bit fragile into tp_first_run_node_cmp. I originaly started to look into this because of undefined symbols with Firefox PGO builds. These symbols went away with fixing these bug but I am not quite sure how. it is possible that there is another problem in lto_blanced_map but even after reading the noreorder code few times carefuly I did not find it. Other explanation would be that our new qsort with broken comparator due to overflow can actualy remove some entries in the array, but that sounds bit crazy.

2019-12-07PR c++/91678 - wrong error with decltype and location wrapper.Marek Polacek4-0/+15
Compiling this testcase results in a bogus "invalid cast" error; this occurs since the introduction of location wrappers in finish_id_expression. Here we are parsing the decltype expression via cp_parser_decltype_expr which can lead to calling various fold_* and c-family routines. They use non_lvalue_loc, but that won't create a NON_LVALUE_EXPR wrapper around a location wrapper. So before the location wrappers addition cp_parser_decltype_expr would return NON_LVALUE_EXPR <c>. Now it returns VIEW_CONVERT_EXPR<float *>(c), but the STRIP_ANY_LOCATION_WRAPPER immediately following it strips the location wrapper, and suddenly we don't know whether we have an lvalue anymore. And that's sad because then decltype produces the wrong type, causing nonsense errors. * fold-const.c (maybe_lvalue_p): Handle VIEW_CONVERT_EXPR. * g++.dg/cpp0x/decltype73.C: New test.

2019-12-07Fix @multitable handling in texi2pod.plRichard Sandiford2-2/+12
While trying out Dennis's Armv8.6-A patch, I noticed that texi2pod.pl didn't handle the new @multitable correctly. There were two problems: (1) @multitables nested in other @tables inherited the @item type from the enclosing @table. Since the new @multitable is in a @table @samp, we applied @samp markup to the @multitable @items. This in turn meant that it captured the @tab separator in the @item markup. Fixed by pushing an empty item code onto the stack. (2) We didn't handle @headitem. Fixed by enclosing it in italics, like we do for section headings. This causes it to be underlined in the man output. 2019-12-07 Richard Sandiford <richard.sandiford@arm.com> contrib/ * texi2pod.pl: Handle @headitems in @multitables, printing them in italics.

2019-12-06Avoid quadratic behaviour in prune_runtime_alias_test_listRichard Sandiford2-4/+19
prune_runtime_alias_test_list used ordered_remove to remove a merged alias pair, which made the function quadratic when many aliases could be removed. I had a testcase in which these memmoves accounted for an impressive 85% of compile time. The fact that we had so many probably shows a deeper problem, but still, it's easy to remove as we go. 2019-12-06 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-data-ref.c (prune_runtime_alias_test_list): Exit early for empty vectors. Avoid using ordered_remove and instead shuffle the vector as we go. From-SVN: r279038
