* 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.
Implement (in utils/binutils.ml) a simple parser for ELF, Mach-O and PE shared object files. Use it to get rid of libbfd in ocamlobjinfo and to improve the checking of external primitives during linking in ocamlc.
It's not just on Windows that the length of the command passed to Sys.command
can exceed system limits:
- On Linux there is a per-argument limit of 2^17 bytes
(the whole command is a single argument to /bin/sh)
- On macOS with default parameters, the limit is between 70000 and 80000
- On BSDs with default parameters, the limit is around 2^18.
In parallel, response files (@file) are supported by all the C compilers
we've encountered: GCC, Clang, Intel's ICC, and even CompCert. They all
seem to follow quoting rules similar to that of the native shell
for the contents of the response file.
This commit forces the use of a response file when the total size of
the arguments to the linker is greater than 2^16.
Arguments passed via a response file are quoted using Filename.quote
as if they were passed on the command line.

Config.ocamlopt_cflags and Config.ocamlopt_cppflags were solely used by
the driver when compiling .c files passed on the command line. The
behaviour of this should be the same as for `ocamlc -c` and the
inclusion of `-fPIC` in `ocamlc_cflags` only on some systems causes
problems for `ocamlmklib` which behaves as though the two drivers
compile C files identically.
This PR eliminates the separate settings in configure.ac and deprecates
the old variables in Config.
