LIBC_INTRIN \
Make malloc() go 200x faster If pthread_create() is linked into the binary, then the cosmo runtime will create an independent dlmalloc arena for each core. Whenever the malloc() function is used it will index `g_heaps[sched_getcpu() / 2]` to find the arena with the greatest hyperthread / numa locality. This may be configured via an environment variable. For example if you say `export COSMOPOLITAN_HEAP_COUNT=1` then you can restore the old ways. Your process may be configured to have anywhere between 1 - 128 heaps We need this revision because it makes multithreaded C++ applications faster. For example, an HTTP server I'm working on that makes extreme use of the STL went from 16k to 2000k requests per second, after this change was made. To understand why, try out the malloc_test benchmark which calls malloc() + realloc() in a loop across many threads, which sees a a 250x improvement in process clock time and 200x on wall time The tradeoff is this adds ~25ns of latency to individual malloc calls compared to MODE=tiny, once the cosmo runtime has transitioned into a fully multi-threaded state. If you don't need malloc() to be scalable then cosmo provides many options for you. For starters the heap count variable above can be set to put the process back in single heap mode plus you can go even faster still, if you include tinymalloc.inc like many of the programs in tool/build/.. are already doing since that'll shave tens of kb off your binary footprint too. Theres also MODE=tiny which is configured to use just 1 plain old dlmalloc arena by default Another tradeoff is we need more memory now (except in MODE=tiny), to track the provenance of memory allocation. This is so allocations can be freely shared across threads, and because OSes can reschedule code to different CPUs at any time.

LIBC_STR \
Add LLVM libcxxabi (#1063) * third_party: Add libcxxabi Added libcxxabi from LLVM 17.0.6 The library implements the Itanium C++ exception handling ABI. * third_party/libcxxabi: Enable __cxa_thread_atexit Enable `__cxa_thread_atexit` from libcxxabi. `__cxa_thread_atexit_impl` is still implemented by the cosmo libc. The original `__cxa_thread_atexit` has been removed. * third_party/libcxx: Build with exceptions Build libcxx with exceptions enabled. - Removed `_LIBCPP_NO_EXCEPTIONS` from `__config`. - Switched the exception implementation to `libcxxabi`. These two files are taken from the same `libcxx` version as mentioned in `README.cosmo`. - Removed `new_handler_fallback` in favor of `libcxxabi` implementation. - Enable `-fexceptions` and `-frtti` for `libcxx`. - Removed `THIRD_PARTY_LIBCXX` dependency from `libcxxabi` and `libunwind`. These libraries do not use any runtime `libcxx` functions, just headers. * libc: Remove remaining redundant cxa functions - `__cxa_pure_virtual` in `libcxxabi` is also a stub similar to the existing one. - `__cxa_guard_*` from `libcxxabi` is used instead of the ones from Android. Now there should be no more duplicate implementations. `__cxa_thread_atexit_impl`, `__cxa_atexit`, and related supporting functions, are still left to other libraries as in `libcxxabi`. `libcxxabi` is also now added to `cosmopolitan.a` to make up for the removed functions. Affected in-tree libraries (`third_party/double-conversion`) have been updated.

LIBC_TINYMATH \
Release Cosmopolitan v3.8.0 This change switches c++ exception handling from sjlj to standard dwarf. It's needed because clang for aarch64 doesn't support sjlj. It turns out that libunwind had a bare-metal configuration that made this easy to do. This change gets the new experimental cosmocc -mclang flag in a state of working so well that it can now be used to build all of llamafile and it goes 3x faster in terms of build latency, without trading away any perf. The int_fast16_t and int_fast32_t types are now always defined as 32-bit in the interest of having more abi consistency between cosmocc -mgcc and -mclang mode.

Get --ftrace working on aarch64 This change implements a new approach to function call logging, that's based on the GCC flag: -fpatchable-function-entry. Read the commentary in build/config.mk to learn how it works.
