While investigating the Solaris 11/x86 testsuite results, I noticed that some 64-bit libgomp test cases were failing. The failure boils down to the attached tie.c program.
If compiled/linked with GNU as/Sun ld, the resulting binary SEGVs: $ gcc -m64 -fopenmp -o tie.sun tie.c $ ./tie.sun Segmentation Fault If instead GNU as and ld are used, everything works fine: $ gcc -m64 -fopenmp -o tie.gnu tie.c $ ./tie.gnu $ As described in an initial patch submission, it turns out that the amd64 TLS IE code sequence emitted by gcc doesn't follow the published Solaris 2 ABI, nor the current `ELF Handling for Thread-Local Storage' spec at http://people.redhat.com/drepper/tls.pdf While GNU ld copes with that just fine, Sun ld cannot handle this and breaks the code emitted by gcc. -- Summary: amd64 TLS IE code sequence on Solaris 2/x86 violates spec Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ro at gcc dot gnu dot org GCC build triplet: i386-pc-solaris2.11 GCC host triplet: i386-pc-solaris2.11 GCC target triplet: i386-pc-solaris2.11 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43309
