[Patch, committed] PR fortran/101123 - [11/12 Regression] Invalid code for MAX0 with -fdefault-integer-8

As confirmed in the PR by Jakub, there was a bad conversion of the result of min0/max0 to the result type. We should just unconditionally convert in all cases. As a benefit, this also fixes pr100283. Committed after regtesting. Thanks, Harald Fortran - fix conversion to result type for the min

[PATCH 5/5] Fortran: Re-enable 128-bit integers for AMD GCN

This patch reverts the part of Tobias's patch for PR target/96306 that disables 128-bit integer support for AMD GCN. OK for mainline (assuming the previous patches are in first)? Thanks, Julian 2021-06-18 Julian Brown libgfortran/ PR target/96306 * configure.ac: Remove stanz

[PATCH 0/5] amdgcn: Improve TImode support

This patch series extends TImode support for AMD GCN (see e.g. PR96306 and PR95730). This fixes several test failures that appear at present, and enables use of a 128-bit integer "omp_depend_kind" for OpenMP 5.0. Tested with offloading to AMD GCN. Further commentary on invididual patches. Thanks,
