--- Comment #11 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:88709c4a1e6f8b69a33897a1ab46b8d66c4569c4 commit r13-4824-g88709c4a1e6f8b69a33897a1ab46b8d66c4569c4 Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Dec 21 09:10:35 2022 +0100 modula2: Fix lto profiledbootstrap on powerpc64le-linux and s390x-linux [PR108153] Lto profiledbootstrap was failing for me on {powerpc64le,s390x}-linux with modula 2 enabled, with: cc1gm2: internal compiler error: the location value is corrupt 0x11a3d2d m2assert_AssertLocation(unsigned int) ../../gcc/m2/gm2-gcc/m2assert.cc:40 0x11a3d2d m2statement_BuildAssignmentTree ../../gcc/m2/gm2-gcc/m2statement.cc:177 ICE. The problem was that caller (m2assert_AssertLocation used location_t M2Options_OverrideLocation (location_t); prototype with the libcpp/line-map.h typedef unsigned int location_t; typedef, but the callee defined in Modula 2 was using: TYPE location_t = INTEGER ; and PROCEDURE OverrideLocation (location: location_t) : location_t ; Now, on powerpc64le-linux unsigned int is returned and passed zero extended into 64-bits, while signed int is returned and passed sign-extended into 64-bits and Modula 2 INTEGER is signed 32-bit type, so when the caller then compared M2Options_OverrideLocation (location) != location and powerpc64le-linux performed the comparison as 64-bit compare, there was a mismatch for location_t of 0x8000007 or others with the MSB set. Fixed by making Modula 2 location_t a CARDINAL, which is 32-bit unsigned type. 2022-12-21 Jakub Jelinek <ja...@redhat.com> PR modula2/108153 * gm2-gcc/m2linemap.def (location_t): Use CARDINAL instead of INTEGER.
