2015-03-16sim: mcore/microblaze: clean up a bitMike Frysinger8-272/+319

2015-03-16sim: rename tconfig.in to tconfig.hMike Frysinger109-404/+410
Rather than manually include tconfig.h when we think we'll need it (which is error prone as it can define symbols we expect from config.h), have it be included directly by config.h. Since we know we have to include that header everywhere already, this will make sure tconfig.h isn't missed. It should also be fine as tconfig.h is supposed to be simple and only set up a few core defines for the target. This allows us to stop symlinking it in place all the time and just use it straight out of the respective source directory.

2015-03-15sim: dv-sockser: push module init prototype downMike Frysinger24-91/+68
Pull out the duplicated dv_sockser_install prototype from the tconfig.in files and put it in the one place it gets used -- sim-module.c. This is still arguably incorrect, but it's better than the status quo where the tconfig.in has to include header files and duplicate the dv-sockser func. The tconfig header is meant to be simple and contain a target defines.

Fix the type of the local var to match the function it is passed to.
2015-03-14sim: delete unused sim-inline.c ruleMike Frysinger2-9/+5
This dates back to the start of the repo, but has never really been used. The sim-inline.c file has been checked in to the source, and attempts to build it in the build tree leads to a circular dep warning from make. It also doesn't produce a file that is usable -- it can't be compiled. Punt!

This triggers a bunch of new warnings, so fix some of them.
2015-03-14sim: make nrun the default run programMike Frysinger47-37/+157
We want people to stop using the run.c frontend, but it's hard to notice when it's still set as the default. Lets flip things so nrun.c is the default, and users of run.c will get an error by default. We turn that error into a warning for existing sims so we don't break them -- this is mostly meant for people starting new ports.
2015-03-14S/390: Disable relocation sort against code sections.Andreas Krebbel4-0/+21
When downgrading from GD to IE model we rewrite the call to __tls_get_offset to a 64 bit load instruction. This relies on the fact that the additional relocation for the call target has already been executed when doing the rewrite. f1018: e3 20 d0 00 00 04 lg %r2,0(%r13) f101e: c0 e5 00 00 00 00 brasl %r14,f101e <__res_init+0x1e> f101e: R_390_TLS_GDCALL __libc_resp f1020: R_390_PLT32DBL __tls_get_offset+0x2 0000000f1020 39f6c00000014 R_390_PLT32DBL 0000000000000000 __tls_get_offset + 2 0000000f101e 3afb700000026 R_390_TLS_GDCALL 0000000000000008 __libc_resp + 0 Due to the reloc sorting the order changed an the PLT32DBL reloc is executed after the rewrite and overwrites part of the load instruction with garbage. bfd/ 2015-03-14 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * elf-s390-common.c (elf_s390_elf_sort_relocs_p): Don't sort relocs against code sections. * elf32-s390.c: Define elf_backend_sort_relocs_p. * elf64-s390.c: Likewise.

The SIM_AC_COMMON macro already checks for a bunch of headers, so specific sim ports need not do it themselves.

2015-03-14sim: move sim-io.h to sim-assert.hMike Frysinger3-1/+8
Since sim-endian.c doesn't actually use sim_io funcs, it's weird to include the sim-io.h header here. It's doing so only for the assert header. So lets relocate the include to the right place.

2015-03-13Remove HPUXJan Kratochvil25-7390/+88
IIUC it is a pre-requisite for IPv6 support, some UNICes do not support getaddrinfo required for IPv6. But coincidentally such UNICes are no longer really supported by GDB. Therefore it was concluded we can remove all such UNICes and then we can implement IPv6 easily with getaddrinfo. In mail Re: getaddrinfo available on all GDB hosts?

Use kinfo_getvmmap from libutil on FreeBSD to enumerate memory regions in a running process instead of /proc/<pid>/map. FreeBSD systems do not mount procfs by default, but kinfo_getvmmap uses a sysctl that is always available.

2015-03-11Create gdb/break-catch-syscall.cSergio Durigan Junior4-600/+696
This commits cleans up the gdb/breakpoint.c file and moves everything that is related to the 'catch syscall' command to the new file gdb/break-catch-syscall.c. This is just code movement, and the only new part is the adjustment needed on 'catching_syscall_number' to use the new 'breakpoint_find_if' function insted of relying on the ALL_BREAKPOINTS macro. Tested by running the 'gdb.base/catch-syscall.exp' testcase. gdb/ChangeLog: 2015-03-11 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (SFILES): New source break-catch-syscall.c.

2015-03-11Implement breakpoint_find_ifSergio Durigan Junior3-0/+36
This commit implements the 'breakpoint_find_if' function, which allows code external to gdb/breakpoint.c to iterate through the list of 'struct breakpoint *'. This is needed in order to create the 'gdb/break-catch-syscall.c' file, because one of its functions (catching_syscall_number) needs to do this iteration. My first thought was to share the ALL_BREAKPOINTS* macros on gdb/breakpoint.h, but they use a global variable local to gdb/breakpoint.c, and I did not want to share that variable. So, in order to keep the minimal separation, I decided to implement this way of iterating through the existing 'struct breakpoint *'. This function was based on BFD's bfd_sections_find_if. If the user-provided function returns 0, the iteration proceeds. Otherwise, the iteration stops and the function returns the 'struct breakpoint *' that is being processed. This means that the return value of this function can be either NULL or a pointer to a 'struct breakpoint'. gdb/ChangeLog: 2015-03-11 Sergio Durigan Junior <sergiodj@redhat.com> * breakpoint.c (breakpoint_find_if): New function. * breakpoint.h (breakpoint_find_if): New prototype.

2015-03-11Implement remote_bfd_iovec_statGary Benson8-12/+211
This commit adds a new packet "vFile:fstat:" to the remote protocol that can be used by to retrieve information about files that have been previously opened using vFile:open. vFile:fstat: support is added to GDB, and remote_bfd_iovec_stat is implemented using it. If vFile:fstat: is not supported by the remote GDB creates a dummy result by zeroing the supplied stat structure and setting its st_size field to INT_MAX. This mimics GDB's previous behaviour, with the exception that GDB did not previously zero the structure so all other fields would have been returned unchanged, which is to say very likely populated with random values from the stack. gdb/ChangeLog: * remote-fileio.h (remote_fileio_to_host_stat): New declaration. * remote-fileio.c (remote_fileio_to_host_uint): New function.
