Add Sys.mkdir
 (commit: 9a7a17c)

Use Sys.mkdir in ocamltest instead of shell call
 (commit: 99f56de)

Remove incorrect stub in ocamltest_stdlib_stubs.c

Miscopied from win32unix.
 (commit: 496cc8b)

Add Sys.rmdir
 (commit: f341db8)

Add Ocamltest_stdlib.Unix.has_symlink

Replaces the duplicated C stub. Functions from Unix must be explictly
imported.
 (commit: 9bc33d9)

Remove use of rm -rf from ocamltest
 (commit: fc0abfa)

Remove use of ln -sf from ocamltest

tools/ci/inria/extra-checks: print each command before its execution
 (commit: 5cb2218)

tools/ci/inria/extra-checks: stop mentionninig world.opt explicitly

this is now what's happening by default when the bytecode compiler
has not been disabled, and it has not, here.
 (commit: 2d927d8)

tools/ci/inria/extra-checks: fix another typo
 (commit: f3e7475)

tools/ci/inria/extra-checks: stop mentionning the world target

This change is similar to the one in commit 2d927d8be6efcea7e3f.

fix floatarray.ml on 32-bit

Trivial correction to stdlib/HACKING.adoc
 (commit: 8905edd)

Fix type mismatches between definition and declaration (#9830)

The C global variable caml_fl_merge and the C function
caml_spacetime_my_profinfo (bytecode version) were declared and
defined with different types.  This is undefined behavior and
can cause link-time errors with link-time optimization (LTO).

Closes: #9825
 (commit: 1964506)

Add a failing test for #show with -short-paths.
 (commit: aa06fa8)

Revert to printing types as 'nonrec' to avoid a bug

Add Bigarray 'init' functions (#9779)

Add Bigarray init functions.
 (commit: 395a47e)

Get rid of the YACCFLAGS build variable

It was not used, except in lex/Makefile where this commit replaces its
unique occurrence by its definition in the same file.
 (commit: df9d60f)

Restrict 'test_locations' to not run with afl active

The AFL code generator alters the generated output and the
expect tests fail.  This test is already restricted to 64-bit
only architectures for similar reasons (the output locations
change).

Also updates the expected outputs to account for the extra line
in the test case now.

Fixes #9822
 (commit: 829b00b)

Build system: honour the CFLAGS and CPPFLAGS build variables

With this commit, it becomes possible to provide C compiler and preprocessor
flags to use in addition to those defined by the build system.

As required by the GNU coding standards, the flags can be provided
either at configure or at make invocation.

The provided CFLAGS and CPPFLAGS will also be taken into account
when C code is compiled by ocamlc/ocamlopt.

This commit removes the explicit reference to CFLAGS in the
configuration for the xlc compiler, since it is not necessary any longer.
 (commit: f3ff133)

Simplify the tools/ci/inria/extra-checks script

Use the ability to pass flags to the C compiler at configure time
to simplify this CI script.

Looking at the diff, it may seem that some flags like -fwrapv,
-fno-strict-aliasing, -Wall and -Werror got lost by this commit.
It is actually not the case. In its previous version, this script was
overriding the flags as defined by the compiler's build system, so it
had to provide a rather exhaustive list of flags. Now one only needs to
add the flags specific to the build one wishes to do. The flags mentionned above*
are provided by the compiler's build system so they do not need to be mentionned
here any longer.

Build system: use OC_CFLAGS and CFLAGS even during the link stage
 (commit: 478127f)

Introduce the check-typo Jenkins pipeline
 (commit: bc62fae)

Inria CI: define the dune-build job as a Jenkins pipeline
 (commit: a59b147)

tools/ci/inria/README.md: typographical improvements
 (commit: 13a500f)

Always report failures of Inria CI's dune-build job

For the time being, let's report all the failures of this job
and not only its regressions.
 (commit: 756f639)

Release info: ocaml-src and ocaml-manual
 (commit: eacd3c3)

dune-build: send e-mails only for regressions
 (commit: 697242f)

Split Inria CI's extra-checks job, take #1

This job did actually do two different things:

1. Check that the compiler can be built without the world.opt target

2. Run sanitizers

This commit thus splits the extra-checks job into two separate
ones that are defined as Jenkins pipeline jobs named sanitizers and
step-by-step-build.
 (commit: c89c464)

Split the extra-checks job, take #2
 (commit: 541ade5)

tools/ci/inria/step-by-step-build/script: fixes
 (commit: 5acc76e)

Make the sanitizers and step-by-step-build CI jobs less verbose

Now that these jobs work, make them report only regressions
