This should hopefully be fixed in the master branch of the Git repository by the commit https://sourceware.org/git/gitweb.cgi?p=libabigail.git;a=commit;h=aa15698aaf8cc354c09dee0b1a0d6a631ee4a403. The fix should be available in the 1.7 version of libabigail. |
Created attachment 12216 [details] dpdk library compiled with clang that exhibits the issue Comparing the attached file (with abidiff) against its ABI representation (generated with abidw) should yield the empty set. Yet, it does yield this bogus result: $ abidiff librte_bus_dpaa.so.20.0 librte_bus_dpaa.so.20.0.abi Functions changes summary: 0 Removed, 1 Changed (25 filtered out), 0 Added functions Variables changes summary: 0 Removed, 0 Changed, 0 Added variable 1 function with some indirect sub-type change: [C]'function qman_portal* fsl_qman_fq_portal_create(int*)' at qman_driver.c:129:1 has some indirect sub-type changes: return type changed: in pointed to type 'struct qman_portal' at qman.c:63:1: type size hasn't changed 1 data member changes (2 filtered): type of 'qm_portal qman_portal::p' changed: type size hasn't changed 1 data member change: type of 'qm_mc qm_portal::mc' changed: type size hasn't changed 1 data member change: type of 'qm_mc_result* qm_mc::rr' changed: in pointed to type 'struct qm_mc_result' at fsl_qman.h:1014:1: type size hasn't changed 1 data member change: $
