2016-06-13gdb: Use UNSUPPORTED not XFAIL for unsupported target featuresAndrew Burgess19-41/+41
If a target does not support making function calls from GDB then in a number of test files, we currently report an XFAIL and skip some, or all of the tests. This commit changes the XFAIL to an UNSUPPORTED as this seems more appropriate in these cases. Some of the tests used bug ID 2416 to be reported in the XFAIL. In the current GDB bugzilla bug 2416 has nothing to do with calling target functions from GDB. gdb/testsuite/ChangeLog: * gdb.base/call-ar-st.exp: Report unsupported rather than xfail for unsupported target features. * gdb.base/call-rt-st.exp: Likewise. * gdb.base/call-sc.exp: Likewise. * gdb.base/call-signal-resume.exp: Likewise. * gdb.base/call-strs.exp: Likewise. * gdb.base/callexit.exp: Likewise. * gdb.base/callfuncs.exp: Likewise. * gdb.base/nodebug.exp: Likewise. * gdb.base/printcmds.exp: Likewise. * gdb.base/ptype.exp: Likewise. * gdb.base/structs.exp: Likewise. * gdb.base/unwindonsignal.exp: Likewise. * gdb.cp/gdb2495.exp: Likewise. * gdb.cp/templates.exp: Likewise. * gdb.cp/virtfunc.exp: Likewise. * gdb.threads/hand-call-in-threads.exp: Likewise. * gdb.threads/interrupted-hand-call.exp: Likewise. * gdb.threads/thread-unwindonsignal.exp: Likewise.

2016-06-10S/390: Dump unknown instructions according to their length.Andreas Krebbel2-17/+48
Unknown instructions are currently just dumped as .long 1234. On S/390 we can do a bit better since the instruction length is encoded in the opcode. That way also unknown instructions can be skipped according to their real length. That way we can continue correctly after that instruction. However, there are also some drawbacks with that behavior when dumping data. So for now that behavior is only enabled for text section but even there it might mess things up when having a literal pool embedded in the code. Therefore I've left the feature disabled by default and have added the -Minsnlength option to enable it explicitely. opcodes/ChangeLog: 2016-06-10 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * s390-dis.c (option_use_insn_len_bits_p): New file scope variable.

2016-06-08i386: Test external function reference without PLTH.J. Lu29-0/+876
To call an external function, the direct branch to the PLT entry can be replaced by an indirect branch via the GOT slot, which is similar to the first instruction in the PLT slot. Instead using the PLT slot as function address, the function address is retrieved from the GOT slot. The R_386_GOT32X relocation can be used to compute the address of the symbol’s GOT entry without base register when PIC is disabled. In non-PIC executable, call/jmp *func@GOT should be used for indirect branch via the GOT slot and movl func@GOT, %eax should be used to load function address. Unlike PIC case, no register is needed to access GOT. If linker determines the function is defined locally, it converts indirect branch via the GOT slot to direct branch with a nop prefix and converts load via the GOT slot to load immediate or lea. * testsuite/ld-i386/libno-plt-1b.dd: New file. * testsuite/ld-i386/libno-plt-1b.rd: Likewise. * testsuite/ld-i386/no-plt-1a.dd: Likewise. * testsuite/ld-i386/no-plt-1a.rd: Likewise. * testsuite/ld-i386/no-plt-1b.dd: Likewise. * testsuite/ld-i386/no-plt-1b.rd: Likewise. * testsuite/ld-i386/no-plt-1c.dd: Likewise. * testsuite/ld-i386/no-plt-1c.rd: Likewise. * testsuite/ld-i386/no-plt-1d.dd: Likewise. * testsuite/ld-i386/no-plt-1d.rd: Likewise. * testsuite/ld-i386/no-plt-1e.dd: Likewise. * testsuite/ld-i386/no-plt-1e.rd: Likewise. * testsuite/ld-i386/no-plt-1f.dd: Likewise. * testsuite/ld-i386/no-plt-1f.rd: Likewise. * testsuite/ld-i386/no-plt-1g.dd: Likewise. * testsuite/ld-i386/no-plt-1g.rd: Likewise. * testsuite/ld-i386/no-plt-1h.dd: Likewise. * testsuite/ld-i386/no-plt-1h.rd: Likewise. * testsuite/ld-i386/no-plt-1i.dd: Likewise. * testsuite/ld-i386/no-plt-1i.rd: Likewise. * testsuite/ld-i386/no-plt-1j.dd: Likewise. * testsuite/ld-i386/no-plt-1j.rd: Likewise. * testsuite/ld-i386/no-plt-check1a.S: Likewise. * testsuite/ld-i386/no-plt-check1b.S: Likewise. * testsuite/ld-i386/no-plt-extern1a.S: Likewise. * testsuite/ld-i386/no-plt-extern1b.S: Likewise. * testsuite/ld-i386/no-plt-func1.c: Likewise. * testsuite/ld-i386/no-plt-main1.c: Likewise. * testsuite/ld-i386/no-plt.exp: Likewise.

2016-06-08Support i386 TLS code sequences without PLTH.J. Lu32-65/+2751
We can generate i386 TLS code sequences for general and local dynamic models without PLT, which uses indirect call via GOT: call *___tls_get_addr@GOT(%reg) where EBX register isn't required as GOT base, instead of direct call: call ___tls_get_addr[@PLT] which requires EBX register as GOT base. Since direct call is 4-byte long and indirect call, is 5-byte long, the extra one byte must be handled properly. For general dynamic model, 7-byte lea instruction before call instruction is replaced by 6-byte one to make room for indirect call. For local dynamic model, we simply use 5-byte indirect call. TLS linker optimization is updated to recognize new instruction patterns. For local dynamic model to local exec model transition, we generate a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte lea instruction. Since linker may convert call ___tls_get_addr[@PLT] to addr32 call ____tls_get_addr when producing static executable, both patterns are recognized. bfd/ * elf64-i386.c (elf_i386_link_hash_entry): Add tls_get_addr.
