Load the debug information during runtime startup if OCAMLRUNPARAM=b=2.
This guards against the specific case of running out of fds, since the
debug information can't then be loaded.
dereference a pointer before checking it is not a naked pointer.
Algo fix a debug macro changed in PR9742 which could potentially
modify its parameter. It turns out this is not a bug, but the macro
was still particularly dangerous.
This commit adds a new thread-related module Semaphore, implementing
counting semaphores and binary semaphores.
The two kinds of semaphores are presented as two different
abstract types in two sub-modules, Counting and Binary.
* remove the unused is_native_tail_call_heuristic forward reference
This forward-reference from Lambda to Asmcomp was used to generate
machine-specific tailcall information in -annot output; this only use
was removed in 57d329e07b, so we can now
remove it to simplify the codebase.
The logic was non-trivial and might be useful again in the future.
* [minor] testsuite: convert warnings/w51.ml to an expect-test
* [minor] translattribute: refactor attribute payload deconstruction
* [@tailcall false]: warn if the call *is* a tailcall
(+ constructor renaming suggested by Nicolás during review)
* Changes
* testsuite: add an example with the 'invalid payload' exception
(suggested by Nicolás during review)
The Spacetime memory profiler is not going to be supported in Multicore OCaml, and is already broken by some of the related changes in OCaml 4.12. The core development team decided to remove Spacetime support from OCaml 4.12.
- Mutex.lock raises Sys_error if the mutex is already locked by the
calling thread.
- Mutex.unlock raises Sys_error if the mutex is unlocked or locked
by another thread.
Add the corresponding tests.

This is selected at configure-time, option --enable-naked-pointers-checker.
The major GC warns when it detects out-of-heap pointers that could cause the no-naked-pointers runtime system to crash.
This is supported on x86-64 only, but on all ports (Unix and Windows).
Added tests involving naked pointers in tests/runtime-naked-pointers
