2024-01-12	Update copyright year range in header of all files managed by GDB	Andrew Burgess	1	-1/+1
	This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-11-21	gdb: Replace gdb::optional with std::optional	Lancelot Six	1	-1/+1
	Since GDB now requires C++17, we don't need the internally maintained gdb::optional implementation. This patch does the following replacing: - gdb::optional -> std::optional - gdb::in_place -> std::in_place - #include "gdbsupport/gdb_optional.h" -> #include <optional> This change has mostly been done automatically. One exception is gdbsupport/thread-pool.* which did not use the gdb:: prefix as it already lives in the gdb namespace.

2023-01-01	Update copyright year range in header of all files managed by GDB	Joel Brobecker	1	-1/+1
	This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-05-26	Finalize each cooked index separately	Tom Tromey	1	-0/+121
	After DWARF has been scanned, the cooked index code does a "finalization" step in a worker thread. This step combines all the index entries into a single master list, canonicalizes C++ names, and splits Ada names to synthesize package names. While this step is run in the background, gdb will wait for the results in some situations, and it turns out that this step can be slow. This is PR symtab/29105. This can be sped up by parallelizing, at a small memory cost. Now each index is finalized on its own, in a worker thread. The cost comes from name canonicalization: if a given non-canonical name is referred to by multiple indices, there will be N canonical copies (one per index) rather than just one. This requires changing the users of the index to iterate over multiple results. However, this is easily done by introducing a new "chained range" class. When run on gdb itself, the memory cost seems rather low -- on my current machine, "maint space 1" reports no change due to the patch. For performance testing, using "maint time 1" and "file" will not show correct results. That approach measures "time to next prompt", but because the patch only affects background work, this shouldn't (and doesn't) change. Instead, a simple way to make gdb wait for the results is to set a breakpoint.
