This set of patches is for PR libfortran/101305, about bugs in
ISO_Fortran_binding.h's type kind/size encodings, and also incorrect
kind/size mappings in CFI_establish. For instance,
ISO_Fortran_binding.h had hard-wired encodings that ptrdiff_t and long
are 8 bytes that are clearly incorrect on a 32-bit target, and other
encodings like CFI_type_int_fast8_t and CFI_type_long_double were
incorrect on some 64-bit targets too. So part of this patch involves
using sizeof in the CFI_type_* macro definitions, instead of literal
constants.
Another difficulty is that the 2018 Fortran standard requires that the
CFI_type_* macros for C types not supported by the Fortran processor
have negative values. Tobias contributed some scripting to check for
that; now ISO_Fortran_binding.h is generated at build time from
fragments in the libgfortran source directory.
The remaining parts of the patch fix up related bugs in CFI_establish
for types whose size isn't directly encoded in the corresponding
CFI_type_* macro, and adjust include paths for ISO_Fortran_binding.h
in the test suite.
Jose has posted a patch that fixes some additional bugs in type/size encodings
in descriptors passed to and from C:
https://gcc.gnu.org/pipermail/fortran/2021-June/056154.html
and there remains a messy bug (PR fortran/100917) relating to
ambiguity in handling long double on some targets -- specifically, on
x86_64 targets that have both 80-bit long doubles with a storage size
of 16 and a true 128-bit floating-point format, the GFC descriptor
representation can't tell them apart.
I tested these patches on i686-pc-linux-gnu with both -m32 and -m64
multilibs.

Additionally, not all targets support all the defined type encodings, and the Fortran standard requires those macros to have a negative value. This patch changes ISO_Fortran_binding.h to use sizeof instead of hard-coded sizes, and assembles it from fragments that reflect the set of types supported by the target. 2021-07-13 Sandra Loosemore <sandra@codesourcery.com> Tobias Burnus <tobias@codesourcery.com> libgfortran/ PR libfortran/101305 * ISO_Fortran_binding.h: Fix hard-coded sizes and split into... * ISO_Fortran_binding-1-tmpl.h: New file. * ISO_Fortran_binding-2-tmpl.h: New file. * ISO_Fortran_binding-3-tmpl.h: New file. * Makefile.am: Add rule for generating ISO_Fortran_binding.h.

I personally do not like current (preexisting) the wording in the comment – and CFI_FAILURE is also not listed, which is also not part of Fortran standard.

Well, given that the original patch in this thread was for tests outside the ts29113 testsuite, any fix has to go someplace where those tests would pick it up too. I'm not seeing the include path failures Tobias is seeing, so I can't confirm his change fixes them, either. When I do "make check-fortran" in my build tree, it seems to be finding the include files because of there being a pile of -B options added to the gfortran command line. I don't know where those are coming from, or why this isn't working for Tobias. :-S -Sandra ^ permalink raw reply [flat|nested] 19+ messages in thread

I have no idea why it did not work – nor why it now works. I did now (again?): * Reset all patches + re-apply your three patches * Bootstrap into an empty directory with $ ..../configure --prefix=... --enable-multiarch --enable-languages=c,c++,fortran,lto,objc $ make -j12 && make install $ cd gcc $ make check-fortran RUNTESTFLAGS="dg.exp=ISO_Fortran_binding_1.f90 --target_board=unix\{,-m32\}" and now I got: === gfortran Summary for unix === # of expected passes 12 === gfortran Summary for unix/-m32 === # of expected passes 12 Thus, it (mostly) works. (I also did a more complete 'make check-fortran' run.) * * * I did say that it mostly works because of: $ find x86_64-pc-linux-gnu/ -name ISO_Fortran_binding.h x86_64-pc-linux-gnu/libgfortran/ISO_Fortran_binding.h x86_64-pc-linux-gnu/32/libgfortran/ISO_Fortran_binding.h And when looking at the -B lines, I see for the '' alias '-m64' run: -B.../build/gcc/testsuite/gfortran/../../ -B.../build/x86_64-pc-linux-gnu/./libgfortran/ -B.../build/x86_64-pc-linux-gnu/./libgfortran/.libs -B.../build/x86_64-pc-linux-gnu/./libquadmath/.libs which is fine (second line ensures the ISO*.h file is found.) But for -m32, I see: -B.../build/gcc/testsuite/gfortran/../../ -B.../build/x86_64-pc-linux-gnu/./libgfortran/ -B.../build/x86_64-pc-linux-gnu/32/libgfortran/.libs -B.../build/x86_64-pc-linux-gnu/32/libquadmath/.libs That also works, but it uses again the same directory for ISO*.h, such that the -m64 header file is used instead of the -m32 one. * * * I am not sure whether it really matters – the differences between the header files is (on x86-64-gnu-linux): -#define CFI_type_int128_t (CFI_type_Integer + (16 << CFI_type_kind_shift)) -#define CFI_type_int_least128_t (CFI_type_Integer + (16 << CFI_type_kind_shift)) -#define CFI_type_int_fast128_t (CFI_type_Integer + (16 << CFI_type_kind_shift)) +#define CFI_type_int128_t -2 +#define CFI_type_int_least128_t -2 +#define CFI_type_int_fast128_t -2 There might be larger differences on other multi-arch systems, but at least for x86-64, it seems to be harmless. (-2 = not available). For instance, there might be an issue on Windows. (I keep forgetting what sizeof(long) is with -m64 – is is the same as sizeof(int) as with -m32? Or is it 64bit with -m64?) * * * Thus, I am puzzled why it failed before and not longer. But given that it works now: LGTM, thanks for the patch and sorry for the confusion!

Unfortunately, I could not get this to work. For installed-tree testing, this resulted in diagnostics about a nonexistent directory on the include path. In my i686-pc-linux-gnu build I was having other problems when I tried build-tree testing using make check-gfortran RUNTESTFLAGS="--target-board=localhost/m64" or similar variants of --target-board (it seemed to be ignoring all the xfails?) so I did not think that could be the way people who normally test in the build tree can be doing it. And when I tried a recipe like make check-gfortran RUNTESTFLAGS="ts29113.exp --tool_opts='-m64'" it found the ISO_Fortran_binding.h via the correct /64-specific path via a -B option, same as for installed-tree testing. Since the patch was already approved without additional hacks to include file paths, I went ahead and pushed it as-is. If somebody can provide me with an exact recipe for reproducing failures to find the include file, I'll take another stab at it, but TBH this is far from my area of expertise. :-( BTW, I can't find any documentation for what get_multilibs is supposed to do.

I guess so – and that's what I did. However, I had to ensure that it gets reset otherwise it picks up the wrong header in multilib runs; this also affects the -B$specpath/libgfortran bit, but I think that makes sense. > Though, I guess we need that mostly for the C FE, so perhaps it needs to go > at the start of additional_flags=, whether TEST_ALWAYS_FLAGS is empty or > not. For the main testsuite (gcc/testsuite/*fortran*/), I believe the patch above is sufficient as everything runs through GFORTRAN_UNDER_TEST. I am also inclined not to add flags to TEST_ALWAYS_FLAGS which then might get applied to other/pure C/C++ tests. Regarding libgomp: that one uses xgcc for the compilation. I don't really see a need to use the Fortran array descriptor from a C program in libgomp's testsuite. Thus, I am inclined to ignore libgomp. Otherwise, as libgomp does not gfortran_init and handles libraries separately, I think the code needs to be put into libgomp.*fortran/fortran.exp. Thoughts? Okay?

To recap, it changes three things: * In the testcases, update "..." to "<...>" for the include * -I $specpath/libgfortran - to find the .h file in the build dir (for in-build-tree testing) * Update GFORTRAN_UNDER_TEST The first two are very obvious, the latter applies, when running DejaGNU with, e.g., --target_board=unix\{-m32,-m64\}". Those two multilib configs use different libgfortran build dirs and, hence, the $specpath/libgfortran differs (e.g. x86.../libgfortran + x86.../32/libgfortran). That's fine, except that when gfortran_init sets GFORTRAN_UNDER_TEST. That only happend when it was unset. That's fine, except for multilib test runs, it is not updated when gfortran_init is called for the next multilib run. Thus, in that case the previous settings are used. – For the discussion in this thread, this means the wrong ISO_Fortran_binding.h is read.
