This doesn't seem to handle the powerpc* IBM double double long double. __LDBL_IS_IEC_60559__ isn't defined for this type, because it is far from an IEEE754 type, but it has signaling NaNs - as can be seen in glibc libc/sysdeps/ieee754/ldbl-128ibm/s_issignalingl.c the type is a pair of doubles and whether it is a sNaN or qNaN is determined by whether the first double is a sNaN or qNaN. 2022-01-25 Jakub Jelinek <jakub@redhat.com> * ieee/issignaling_fallback.h (__issignalingl): Define for IBM extended long double are returning __issignaling on the first double.

2022-01-24Fortran: provide a fallback implementation of issignalingFrancois-Xavier Coudert2-4/+241
For targets with IEEE support but without the issignaling macro in libc (currently, everywhere except glibc), this allows us to provide a fallback implementation. In order to keep the code in ieee_helper.c relatively readable, I've put that new implementation in a separate file, issignaling_fallback.h. libgfortran/ChangeLog: * ieee/issignaling_fallback.h: New file. * ieee/ieee_helper.c: Include issignaling_fallback.h when target does not define issignaling macro. gcc/testsuite/ChangeLog: * gfortran.dg/ieee/signaling_1.f90: Do not require issignaling. * gfortran.dg/ieee/signaling_2.f90: Add comment. * gfortran.dg/ieee/signaling_3.f90: New test.

The ABI for x87 and x86-32 is not suitable for passing around signaling NaNs in the way IEEE expects.

2022-01-14libgfortran: Partly revert my r12-6498 change to fix Solaris build [PR104006]Jakub Jelinek2-4/+4
In r12-6498 I've added $(version_dep) to BUILT_SOURCES, previously version_dep on Linux used to be a file in $(srcdir), but with my changes it is a generated file in the object directory (preprocessed version of the $(srcdir) file) and I thought generated files belong to BUILT_SOURCES so that they are cleaned up etc. For Linux that is fine, but it broke parallel builds on Solaris. BUILT_SOURCES is a special variable for automake where automake ensures that for make all, make check and make install all those $(BUILT_SOURCES) are generated before actually starting building in parallel the various object files. That way we can avoid hacks like: $(patsubst %.F90,%.lo,$(notdir $(filter %.F90,$(prereq_SRC)))): kinds.inc c99_protos.inc $(patsubst %.c,%.lo,$(notdir $(filter %.c,$(prereq_SRC)))): kinds.h $(patsubst %.f90,%.lo,selected_real_kind.f90): selected_real_kind.inc $(patsubst %.f90,%.lo,selected_int_kind.f90): selected_int_kind.inc $(patsubst %.F90,%.lo,ieee_exceptions.F90): fpu-target.inc $(patsubst %.F90,%.lo,ieee_arithmetic.F90): fpu-target.inc ieee_exceptions.lo $(patsubst %.c,%.lo,fpu.c): fpu-target.h which makes those dependencies explicit but hides it from automake, so that it doesn't throw away its rules for those object files. On Solaris, $(version_dep) contains gfortran.ver and gfortran.ver-sun. gfortran.ver is like on Linux, it can be in $(BUILT_SOURCES), but unfortunately gfortran.ver-sun depends on all the object files being compiled already, so if gfortran.ver-sun appears in $(BUILT_SOURCES), the BUILT_SOURCES function of ensuring the generated files are generated before building object files is gone, almost everything is built before all-am is entered and there are no explicit dependencies that e.g. *.F90 files depend on kinds.inc etc. So, this change reverts that mistake and instead adds $(version_dep) to what is removed during make clean (clean-local in particular). 2022-01-14 Jakub Jelinek <jakub@redhat.com> PR libfortran/104006 * Makefile.am (BUILT_SOURCES): Don't include $(version_dep).

2022-01-11power-ieee128: Fix up byte-swapping for IBM extended real(kind=16)Jakub Jelinek1-2/+36
Here is a patch to fix up the ppc64be vs. ppc64le byteswapping of IBM extended real(kind=16) and complex(kind=16). Similarly to the BT_COMPLEX case it halves size and doubles nelems for the bswap_array calls. Of course for r16_ibm and r16_ieee conversions one needs to make sure it is only done when the on file data is in that format and not in IEEE quad. 2022-01-11 Jakub Jelinek <jakub@redhat.com> * io/transfer.c (unformatted_read, unformatted_write): When byteswapping IBM extended real(kind=16), handle it as byteswapping two real(kind=8) values.

We use the issignaling macro, present in some libc's (notably glibc), when it is available. Compile all IEEE-related files in the library (both C and Fortran sources) with -fsignaling-nans to ensure maximum compatibility. libgfortran/ChangeLog: PR fortran/82207 * Makefile.am: Pass -fsignaling-nans for IEEE files. * Makefile.in: Regenerate. * ieee/ieee_helper.c: Use issignaling macro to recognized signaling NaNs. gcc/testsuite/ChangeLog: PR fortran/82207 * gfortran.dg/ieee/signaling_1.f90: New test. * gfortran.dg/ieee/signaling_1_c.c: New file.

2021-12-31libgfortran: Fix bootstrap on targets without static_assert macro.Iain Sandoe1-2/+2
Although we build the library with GCC which is known to support _Static_assert this might be done on a system without the macro mapping static_assert to the compiler keyword. The use of static_assert introduced with r12-6126-g3430132f3e82 causes bootstrap to fail on such targets, fixed by using the keyword directly. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> libgfortran/ChangeLog: * runtime/string.c (gfc_itoa): Use _Static_assert directly instead of via the static_assert macro.

2021-12-29Fortran: keep values of IEEE_CLASS_TYPE in syncFrancois-Xavier Coudert1-5/+16
Fortran 2018 added some synonyms to the existing values, namely IEEE_NEGATIVE_SUBNORMAL (which is the same as IEEE_NEGATIVE_DENORMAL) and IEEE_POSITIVE_SUBNORMAL (same as IEEE_POSITIVE_DENORMAL). When they were added to the C side, they were not kept in sync with the Fortran part of the library. Thew new values are not used (yet), so it is currently harmless, but better fix it. libgfortran/ChangeLog: * ieee/ieee_helper.c: Fix enum values.
