2018-01-05PR 78534 Change character length from int to size_tJanne Blomqvist3-12/+11
In order to handle large character lengths on (L)LP64 targets, switch the GFortran character length from an int to a size_t. This is an ABI change, as procedures with character arguments take hidden arguments with the character length. I also changed the _size member in vtables from int to size_t, as there were some cases where character lengths and sizes were apparently mixed up and caused regressions otherwise. Although I haven't tested, this might enable very large derived types as well. Also, as there are some places in the frontend were negative character lengths are used as special flag values, in the frontend the character length is handled as a signed variable of the same size as a size_t, although in the runtime library it really is size_t. I haven't changed the character length variables for the co-array intrinsics, as this is something that may need to be synchronized with OpenCoarrays. This is v5 of the patch. v4 was applied but caused breakage on big endian targets. These have been fixed and tested, thanks to access to the GCC compile farm. Overview of v4 of the patch: v3 was applied but had to reverted due to breaking bootstrap. The fix is in resolve.c:resolve_charlen, where it's necessary to check that an expression is constant before using mpz_sgn. Overview of v3 of the patch: All the issues pointed out by FX's review of v2 have been fixed. In particular, there are now new functions gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT instead of a long value. Similarly, gfc_get_int_expr now takes a HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by gfc_extract_hwi. Also, the preliminary work to handle gfc_charlen_type_node being unsigned has been removed. Regtested on x86_64-pc-linux-gnu, i686-pc-linux-gnu and powerpc64-unknown-linux-gnu. Also regtested all three targets by modifying gfortran-dg.exp to also test with "-g -flto", no new failures observed. frontend: 2018-01-05 Janne Blomqvist <jb@gcc.gnu.org> PR fortran/78534 PR fortran/66310 * array.c (got_charlen): Use gfc_charlen_int_kind. * class.c (gfc_find_derived_vtab): Use gfc_size_kind instead of hardcoded kind.

2018-01-02PR libgfortran/83649 Chunk large reads and writesJanne Blomqvist1-8/+42
It turns out that Linux never reads or writes more than 2147479552 bytes in a single syscall. For writes this is not a problem as libgfortran already contains a loop around write() to handle short writes. But for reads we cannot do this, since then read will hang if we have a short read when reading from the terminal. Also, there are reports that macOS fails I/O's larger than 2 GB. Thus, to work around these issues do large reads/writes in chunks. The testcase from the PR program largewr integer(kind=1) :: a(2_8**31+1) a = 0 a(size(a, kind=8)) = 1 open(10, file="largewr.dat", access="stream", form="unformatted") write (10) a close(10) a(size(a, kind=8)) = 2 open(10, file="largewr.dat", access="stream", form="unformatted") read (10) a if (a(size(a, kind=8)) == 1) then print *, "All is well" else print *, "Oh no" end if end program largewr fails on trunk but works with the patch.

2017-11-28PR 53796 Improve INQUIRE(RECL=...) handlingJanne Blomqvist5-16/+36
The current F2018 draft (N2137) specifies behavior of the RECL= specifier in the INQUIRE statement, where it previously was left as undefined. Namely: - If the unit is not connected, RECL= should be given the value -1. - If the unit is connected with stream access, RECL= should be given the value -2. Further, as PR 53796 describes, the handling of RECL= is poor in other ways as well. When the recl is set to the maximum possible (GFC_INTEGER_8_HUGE / LLONG_MAX), which it does by default except for preconnected units, and when INQUIRE(RECL=) is used with a 4 byte integer, the value is truncated and the 4 byte value is thus -1. Fixing this to generate an error is a lot of work, as currently the truncation is done by the frontend, the library sees only an 8 byte value with no indication that the frontend is going to copy it to a 4 byte one. Instead, this patch does a bit twiddling trick such that the truncated 4 byte value is GFC_INTEGER_4_HUGE while still being 0.99999999 * GFC_INTEGER_8_HUGE which is large enough for all practical purposes. Finally, the patch removes GFORTRAN_DEFAULT_RECL which was used only for preconnected units, and instead uses the same approach as describe above.
