The address was loaded from the TOC into register r0. This generated bad code in the "big TOC" case, as r0 was used as index register. The fix is to use another temporary register instead of r0.
Add "arch_power" builtin to ocamltest.
Add test case.
That's because ocamlopt -a doesn't support .cmxa files as arguments.
It is better to reject those files in ocamlmklib than later.
The manual never said that ocamlmklib accepts .cmxa files.
Closes: #3249
This commit removes support for gprof-based profiling (the -p option to ocamlopt). It follows a discussion on the core developers' list, which indicated that removing gprof support was a reasonable thing to do. The rationale is that there are better easy-to-use profilers out there now, such as perf for Linux and Instruments on macOS; and the gprof support has always been patchy across targets. We save a whole build of the runtime and simplify some other parts of the codebase by removing it.
Following on from GPR#851 and GPR#873, this pull request further enhances debugging information in Cmm terms. This was driven both by manually examining the debugger's behaviour and also by a report received from a user regarding substandard DWARF location information.
The compatibility macros (that were introduced while moving bigarray file mapping functions to the Unix library) are no longer necessary, so let's get rid of them.

Most of the time, the C preprocessor needs to be invoked through the C
compiler, e.g. so that the paths to the header files are resolved properly.
In some cases, though, we really need to be able to call the C
preprocessor directly, just to expand macros in .ml files (this only
happens in the testsuite, at the moment). In those cases, it is
simply impossible to call the C preprocessor through the compiler,
e.g. because this would require the input files to have a '.c'
extension, which the OCaml compiler would misinterprete as meaning this file
should be compiled with the C compiler.
Thus, this commit clarifies the distinction between CPP and DIRECT_CPP
and provides both variables to the build system. The ocamltest build system
is also updated to take advantage of this.
We rely on autoconf's macros to detect how to call the C preprocessor
via the C compiler, except for the MSVC port where its value is hard-coded
to guarantee backward compatibility.
After consultation on the core developers' list I am proposing this patch to remove support for compiler plugins.
The main motivations for removing compiler plugins are:
- They are a potential security risk.
- They increase the complexity of the build system and make maintenance of the Dynlink libraries more difficult (although actually, this complexity could probably be reduced after #2268 is merged).
- Many applications of plugins should be able to be expressed by building custom compiler drivers that link against compilerlibs.
* Remove compiler plugins and hooks
* Add new function Dynlink.unsafe_get_global_symbol but keep it outside the documented API.
* Remove otherlibs/dynlink/nodynlink.ml
* Update Changes
* Creating a new section in the first chapter of the manual
* Add an introduction of custom printer for int
* Add an easy example of %a combinator
* Add an example of using the printf function on complex data structure
This GPR restores -vmthread with an adapted version of the deprecation message as an error message and also keeps the use_vmthreads part of ppx contexts.
* Partially revert #2289
* Convert -vmthread to an error
* Neuter use_vmthreads in ppx context
* Remove Clflags.use_vmthreads
This commit adapts Inria's bootstrap CI job to take into account the
removal of the threads library. More precisely, it updates the patch
that removes the sinh primitive from the runtime to not patch
otherlibs/threads/stdlib.ml any longer since this file has been removed
from the repository.
* Delete the deprecated vmthreads library
It was deprecated in 4.08.
* Remove the byte/native argument of init_path
It is no longer necessary.
* Error out when passing --{enable,disable}-vmthreads to ./configure

In OCaml 4.07, Unix.sleepf and Thread.delay were changed so that they
would restart the sleep when interrupted by a signal (error EINTR).
The unintended consequence is that Thread.delay will not run
signal handlers until the full delay has expired. If the effect
of the handler is to raise an exception, as with Sys.catch_break,
the delay is not terminated early.
(This is specific to threaded programs, where asynchronous invocation
of signal handlers is turned off and handlers are only run at the next
leave-blocking-section. Using Unix.sleepf in a non-threaded program
doesn't show the issue because the handler is invoked asynchronously.)
This commit implements a more intuitive behavior, closer to that of 4.06:
signals received during Thread.delay are handled immediately, and if
the handler returns normally, the delay is restarted with the remaining time.
A test is added in testsuite/tests/lib-threads/delayintr.ml
