Prefix may be passed to configure using a Cygwin-style PATH (e.g.
`./configure --prefix ~/local`). Use cygpath to ensure that the correct
version gets written to Makefile.config, or the resulting compiler has
an invalid default stdlib path.
Disallow function sections on arm32, as the simplest way to address issue #9124 and get the CI working on the newer versions of GNU binutils for Raspbian. After this change, configure --enable-function-sections is an error on arm32. When the issue with GNU ld is resolved, this can be added back with appropriate checks on version of binutils.
Closes: #9124
This commit makes it possible to build the OCaml compiler according to
its configuration by simply runnning make. There is no need to specify
neither world nor world.opt explicitly, although the two targets
remain available.
This commit also introduces (and starts making use of) the
NATIVE_COMPILER build variable whosse value is true when the native
compiler is enabled and false otherwise.
* Enable force-safe-string by default
* Run the autogen script
* Add a line to the changelog
* Remove test using the -unsafe-string argument
* Disable program comparison for tests giving different binaries between ocamlopt.opt and ocamlopt.byte after switching to force-safe-string by default
* Add a comment where the compare_programs tests have been disabled to refer to an explaination of the problem
If the user explicitly requests function sections by calling configure
with --enable-function-sections on a target that does not support it,
it's an error at configure time.
Add --enable-function-sections option to configure. With this option,
the compiler will emit each function in a separate named text section,
on supported targets. This enables function reordering using a linker
script. With this option, the compiler also emits caml_hot__code_begin
and caml_hot__code_end sections. This allows a linker script to
move function sections outside of the segments they belong to,
without breaking caml_code_segments.
--with-pic should be adding -fPIC (or equivalent) to $internal_cflags,
not $common_cflags. Additionally, unused variable aspp was being
updated, instead of ASPP.
This commit replaces a few configure command-line options by configuration
variables:
- "--with-dllibs" is replaced by DLLIBS
- "--with-reserved-header-bits" is replaced by RESERVED_HEADER_BITS
- "--with-default-string" is replaced by DEFAULT_STRING
A #! line should not exceed 128 characters (including the \0
terminator). This adds a test - both to the generation of the camlheader
files and also to the -use-runtime flag which falls back to #!/bin/sh
and uses exec to invoke the the interpreter.
This commit removes the remaining traces of support
for the Power/PowerPC architecture with OS other than Linux.
ocamlopt stopped supporting those configurations in 2014,
see commit 8815d7e and following.
Using the clang/llvm assembler avoids an extra dependency on GNU binutils, and that's what 32-bit arm is using.
But in this case, there was a problem with floating point immediates: LLVM thinks that if they're written in hex, they must be integer values between 0 and 255.
Changed them to float literals.
Call the C preprocessor through the C compiler rather than calling it
directly.
This required the definition of a new ocamltest variable,
ocaml_filetype_flag, which makes it possible to override the filetype
inferred by the compiler from the extnesion of the source file.
The Graphics library is now distributed as a separate package.

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.
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.
* 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

This patch removes support for 32-bit Darwin (macOS, iOS, etc) targets on Intel hardware. This enables various special cases to be removed in the i386 backend.
The current version of macOS (Mojave) is the last one that will support 32-bit x86 binaries. The current version of iOS does not support execution of 32-bit binaries any more.
Cygwin is based on newlib, not glibc, and the fma function is not
implemented. Split off HAS_WORKING_FMA from HAS_C99_FLOAT_OPS. Disable
fma for Cygwin64 so that the fma test passes.

--disable-unix-lib, --disable-vmthreads and --disable-str-lib added to
prevent building these three libraries.
ocamldoc, the debugger and caml-tex are automatically disabled if their
prerequisites are not built. Using --enable-debugger and
--enable-ocamldoc will result in errors if these tools cannot be built.
