- Align DLLEXPORT in definitions and declations. There is still a few
cases left, where the declation in the compiler's complex.h disagrees
with the implementation here. For now we can't do anything about that,
but maybe should be revisited in the future.
- Fix the syntax on an .ascii directive that gcc accepted mistakingly, but
clang does not.
I often build the code with -Wmissing-prototypes to ensure that we don't
accidentically pollute the symbol namespace. If we want to provide a
symbol such as isopenlibm(), make sure we also declare it in
<openlibm_math.h>.
This is a bit more consistent with the naming of the other header files
(openlibm_complex.h and openlibm_fenv.h). Re-add an openlibm.h header
that includes all of the public headers as a shorthand.
Fix up all of the source files to include <openlibm_math.h> instead of
<openlibm.h>. While there, fix ordering of the includes.
While there, also modify the install target. We should make sure to
install all openlibm*.h headers. There is still some work to be done:
openlibm_fenv_*.h still depends on some additional bits. I'd propose
that we eventually create an include/openlibm_cdefs.h that contains all
of the macros we need.
OpenLibm has an implementation of fenv.h internally. This may be
problematic in case you want it to build against the host system's
implementation, as it would require you to somehow take the fenv.h file
out of the compiler search path.
Simply use a different naming scheme, similar to openlibm.h and
openlibm_complex.h. If we want to build against the host's fenv.h, we
can simply add an '#include <fenv.h>' from within this header.
Instead of using all sorts of operating system specific constructs, we
can just query the compiler which byte order is being used. This has the
advantage that the code builds on new platforms without any tweaks.
<sys/cdefs.h> is not a standard header. Instead, we'd better pull in a
common header like <stdio.h>. It is very likely that such a header
already provides the necessary bits.
skip END and add .drectve export in assembly versions
uncomment __strong_reference definition from cdefs-compat.h
use weak references in place of strong references on Mac
add DLLEXPORT to all strong references
