The release of OCaml 4.13.0 is expected for next week.
Since we had a native code generation bug fix and two minor configuration tweaks
since the first release candidate, we are publishing a second release candidate.
If you find any bugs, please report them here:
Florian Angeletti for the OCaml team.
The base compiler can be installed as an opam switch with the following commands
opam update opam switch create 4.13.0~rc2 --repositories=default,beta=git+https://github.com/ocaml/ocaml-beta-repository.git
If you want to tweak the configuration of the compiler, you can switch to the option variant with:
opam update opam switch create <switch_name> --packages=ocaml-variants.4.13.0~rc2+options,<option_list> --repositories=default,beta=git+https://github.com/ocaml/ocaml-beta-repository.git
where <option_list> is a comma separated list of ocaml-option-* packages. For instance, for a flambda and no-flat-float-array switch:
opam switch create 4.13.0~rc2+flambda+nffa --packages=ocaml-variants.4.13.0~rc2+options,ocaml-option-flambda,ocaml-option-no-flat-float-array --repositories=default,beta=git+https://github.com/ocaml/ocaml-beta-repository.git
All available options can be listed with “opam search ocaml-option”.
The source code for the release candidate is also available at these addresses:
#10626, #10628: Wrong reloading of the x86-64 instruction for
integer multiplication by a constant, causing the assembler to
reject the ocamlopt-generated code.
(Xavier Leroy, report by Dave Aitken, review by Vincent Laviron)
#10451, #10635(new in rc2): Replace the use of iconv with a C utility to convert $(LIBDIR)
to a C string constant on Windows when building the runtime. Hardens the
generation of the constant on Unix for paths with backslashes, double-quotes
(David Allsopp, review by Florian Angeletti and Sébastien Hinderer)
