Justine Tunney	f7780de24b	Make realloc() go 100x faster on Linux/NetBSD ... Cosmopolitan now supports mremap(), which is only supported on Linux and NetBSD. First, it allows memory mappings to be relocated without copying them; this can dramatically speed up data structures like std::vector if the array size grows larger than 256kb. The mremap() system call is also 10x faster than munmap() when shrinking large memory mappings. There's now two functions, getpagesize() and getgransize() which help to write portable code that uses mmap(MAP_FIXED). Alternative sysconf() may be called with our new _SC_GRANSIZE. The madvise() system call now has a better wrapper with improved documentation.	2024-07-07 12:40:30 -07:00
Justine Tunney	c4c812c154	Introduce ctl::set and ctl::map ... We now have a C++ red-black tree implementation that implements standard template library compatible APIs while compiling 10x faster than libcxx. It's not as beautiful as the red-black tree implementation in Plinko but this will get the job done and the test proves it upholds all invariants This change also restores CheckForMemoryLeaks() support and fixes a real actual bug I discovered with Doug Lea's dlmalloc_inspect_all() function.	2024-06-23 22:27:11 -07:00
