From 5c864eed944ec825aeee64ab912316cd0e1b3ed9 Mon Sep 17 00:00:00 2001 From: Michael Klemm Date: Thu, 13 Jun 2024 12:42:58 +0200 Subject: [PATCH] Fixes #89403 Moves definitions of the kind arrays into a Fortran MODULE to not only emit the MOD file, but also compile that MODULE file into an object file. This file is then linked into libFortranRuntime.so. Eventually this workaround PR shoud be redone and a proper runtime build should be setup that will then also compile Fortran MODULE files. --- flang/CMakeLists.txt | 1 + flang/module/__fortran_builtin_kinds.f90 | 110 +++++++++++++++++++++ flang/module/iso_fortran_env.f90 | 118 ++++++----------------- flang/runtime/CMakeLists.txt | 1 + flang/tools/f18/CMakeLists.txt | 42 +++++++- flang/tools/flang-driver/CMakeLists.txt | 2 - 6 files changed, 182 insertions(+), 92 deletions(-) create mode 100644 flang/module/__fortran_builtin_kinds.f90 diff --git a/flang/CMakeLists.txt b/flang/CMakeLists.txt index cbe8f1186236a4..070c39eb6e9ab4 100644 --- a/flang/CMakeLists.txt +++ b/flang/CMakeLists.txt @@ -538,3 +538,4 @@ get_clang_resource_dir(HEADER_INSTALL_DIR SUBDIR include) install( FILES include/flang/ISO_Fortran_binding.h DESTINATION ${HEADER_INSTALL_DIR} ) + diff --git a/flang/module/__fortran_builtin_kinds.f90 b/flang/module/__fortran_builtin_kinds.f90 new file mode 100644 index 00000000000000..189055dc26c0cb --- /dev/null +++ b/flang/module/__fortran_builtin_kinds.f90 @@ -0,0 +1,110 @@ +!===-- module/__fortran_bultin_kinds.f90 --=--------------------------------===! +! +!
