2015-03-31sim: cr16/d10v: restore generated headers depMike Frysinger4-0/+12
While cleaning up stale make rules, one too many were deleted. The build system autogenerates static rules, but not generated files.
2015-03-31common: cgen-mem/cgen-ops: fix extern inline handlingMike Frysinger3-2/+9
With newer versions of gcc (5.x), the extern inline we're using with the cgen-{mem,ops} modules no longer work. Since this code really wants the gnu inline semantics, use that attribute explicitly.

2015-03-30sim: arm: convert to nrunMike Frysinger4-153/+160
A lot of cpu state is stored in global variables, as is memory handling. The sim_size support needs unwinding at some point. But at least this is an improvement on the status quo.
2015-03-30sim: arm: delete NEED_UI_LOOP_HOOK handlingMike Frysinger3-20/+8
2015-03-30sim: arm: clean up misc warningsMike Frysinger7-97/+54
Also delete a few unused funcs.
2015-03-30sim: arm: use common configure optionsMike Frysinger4-2/+555
In preparation for converting to nrun, call the common functions that are needed. This doesn't produce any new warnings, and the generated code should be the same.
2015-03-30Remove three redundant wrapper functions in remote.cGary Benson2-27/+15
gdb/ChangeLog: * remote.c (remote_mourn_1): Remove function. Update all callers to use remote_mourn. (extended_remote_mourn_1): Remove function. Update all callers to use extended_remote_mourn. (extended_remote_attach_1): Remove function. Update all callers to use extended_remote_attach.
2015-03-30Properly set sh_info for .rela.plt/rel.plt sectionH.J. Lu7-10/+69
Since .rela.plt/rel.plt section may contain relocations against .got.plt section, we set sh_info for .rela.plt/rel.plt section to .got.plt section index if target has .got.plt section. bfd/ PR ld/18169 * elf-bfd.h (elf_backend_data): Add get_reloc_section. (_bfd_elf_get_reloc_section): New. * elf.c (_bfd_elf_get_reloc_section): Likewise. (assign_section_numbers): Call get_reloc_section to look up the section the relocs apply. * elfxx-target.h (elf_backend_get_reloc_section): Likewise.

2015-03-30sim: arm: move COPRO settings to the makefileMike Frysinger4-29/+12
These values are the same all the time, so just list them directly in the Makefile.

2015-03-30sim: d10v: convert to nrunMike Frysinger7-130/+121
A lot of cpu state is stored in global variables, as is memory handling. The sim_size support needs unwinding at some point. But at least this is an improvement on the status quo.
2015-03-30sim: d10v: delete NEED_UI_LOOP_HOOK handlingMike Frysinger3-21/+8
This hook is used only when linked into gdb, and d10v doesn't have a gdb port anymore. Punt it.

2015-03-30sim: d10v: link in missing testsuiteMike Frysinger3-3/+16
Looks like historical restructuring in this dir lost the d10v-elf subdir and no one noticed in the meantime. Re-add it to the testsuite. There are some failures, but better some tests get run than none at all.
2015-03-30sim: cr16: convert to nrunMike Frysinger6-147/+188

2015-03-30sim: cr16: delete dead codeMike Frysinger2-238/+10
This code is getting in the way of porting to nrun, so just drop it. If anyone actually cares about this cpu, they can revive it.

2015-03-29sim: cr16: add _start symbol to tests [BZ #12385]Mike Frysinger2-0/+7
The current cr16 testsuite sets up _START, but the linker looks for the _start symbol. Add the latter as an alias to the former.

2015-03-29sim: microblaze: convert to nrunMike Frysinger5-193/+176
This port already was storing its cpu state in the sim_cpu structure, so converting it over was pretty easy. It is allocating memory itself still, but we'll fix that up in the future at some point.
2015-03-29sim: mcore/microblaze: delete dead codeMike Frysinger4-115/+15
The mcore port had a few structs/defines that were never used. Similarly, the microblaze port, because it was copied from mcore, has that same dead code, and more. The watchpoint logic was never actually used. Punt it all.
2015-03-29sim: microblaze: start a testsuiteMike Frysinger6-1/+60
Since the sim doesn't have any debug support in it, we can only exit cleanly. But this is still better than nothing. Change the default microblaze sim to not dump the debug load output when running. No other does this, and it breaks the testsuite.
