--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by John David Anglin <dang...@gcc.gnu.org>: https://gcc.gnu.org/g:932b8d077c23986da5279bf8b5d84875de1fb826 commit r14-7015-g932b8d077c23986da5279bf8b5d84875de1fb826 Author: John David Anglin <dang...@gcc.gnu.org> Date: Mon Jan 8 20:27:20 2024 +0000 hppa: Fix bind_c_coms.f90 and bind_c_vars.f90 tests on hppa Commit 6271dd98 changed the default from -fcommon to -fno-common. This silently changed the alignment of uninitialized BSS data on hppa where the alignment of common data must be greater or equal to the alignment of the largest type that will fit in the block. For example, the alignment of `double d[2];' changed from 16 to 8 on hppa64. The hppa architecture requires strict alignment and the linker warns about inconsistent alignment of variables. This change broke the gfortran.dg/bind_c_coms.f90 and gfortran.dg/bind_c_vars.f90 tests. These tests check whether bind_c works between fortran and C. Adding the -fcommon option fixes the tests. Probably, gcc and HP C are now by default inconsistent but that's water under the bridge. 2024-01-08 John David Anglin <dang...@gcc.gnu.org> gcc/testsuite/ChangeLog: PR testsuite/94253 * gfortran.dg/bind_c_coms.f90: Add -fcommon option on hppa*-*-*. * gfortran.dg/bind_c_vars.f90: Likewise.
