2016-01-05libiberty: fix warnings about left shifting a negative value.Nick Clifton2-1/+7
GCC PR 66827 reports some problems with left shifting a negative value: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66827 Of the problems reported only two remain - in libiberty/regex.c: libiberty/regex.c:6970:11: runtime error: left shift of negative value -1 libiberty/regex.c:7165:4: runtime error: left shift of negative value -1 The patch below fixes these errors by casting the value to be shifted to unsigned before the shift occurs. No regressions were found in the libiberty testsuite or bootstrapping gcc (on an x86_64 target).
2016-01-05gdb: score: drop sim file checkMike Frysinger2-3/+4
There has never been a GNU/sim port for the S+Core architecture. It was added to support private code that has (and most likely never will) see the light of day [1]. Punt this as we don't do this for other people. If you want to maintain a proprietary internal build, then that's not really our problem.

2016-01-05sim: msp430: drop duplicate sim_load_file callMike Frysinger2-26/+14
There's no need, or desire, to call sim_load_file from sim_open. The higher levels (gdb/run) take care of calling sim_load for us already.

The output format is a bit different, but the new form matches all the other trace lines. Otherwise, it should be functionally equivalent.
2016-01-05sim: trace: add support for disassemblingMike Frysinger3-1/+119
Some targets have started to add support for calling the disassembler automatically when executing code. Add support for that directly into the trace core.

2016-01-05Fix PR sim/13418: building with --enable-targets=all failsPedro Alves5-1/+30
Multitarget builds currently fail when: (1) simulator support is enabled (the main --target supports target sim) (2) powerpc is included in the --enable-targets list (3) powerpc is not the main/default target (--target) This is because the powerpc sim provides a non-standard API function sim_spr_register_name which gdb/rs6000-tdep.c utilizes. Since the sim does not yet support multitarget, only the sim (if one exists) for the main target is built. When that target isn't powerpc, this function is not available leading to linking errors: rs6000-tdep.c:(.text+0x1e34d): undefined reference to `sim_spr_register_name' Fix this by only using that API if the sim linked in is the powerpc sim. gdb/ChangeLog: 2016-01-05 Pedro Alves <palves@redhat.com> PR sim/13418 * configure.ac: Define WITH_PPC_SIM when linking in the sim and the target is powerpc*. * configure: Regenerate. * config.in: Regenerate.

2016-01-04MIPS/BFD: Move attribute check after ELF file header flag checkMaciej W. Rozycki17-33/+59
We have a problem in that in making compatibility checks while merging private BFD data on the MIPS target we give priority to the attribute check, which may fail and cause the function to abort early on. The problem with this is the ABI compatibility aspect recorded in the attributes is relatively minor compared to aspects recorded in the ELF file header. However the premature exit causes any more important compatibility aspect violated to be masked and not reported to the user once a problem with attributes has been noticed. So move the attribute check after the ELF file header flag check in `_bfd_mips_elf_merge_private_bfd_data', and do not return prematurely there. Take advantage of the resulting grouping of ELF file header handling together and remove the premature success return point for the first input object being handled, letting the code later on figure out output ABI flags even for this object. Update LD test cases according to messages from ELF file header checks now preceding ones from attribute checks. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Move attribute check after ELF file header flag check. ld/ * testsuite/ld-mips-elf/attr-gnu-4-14.d: Update the order of messages expected according to MIPS BFD private data merge changes. * testsuite/ld-mips-elf/attr-gnu-4-24.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-34.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-41.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-42.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-43.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-45.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-46.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-47.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-48.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-49.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-54.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-64.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-74.d: Likewise.

2016-01-04MIPS/BFD: Factor out ELF file header flag checksMaciej W. Rozycki2-182/+200
Factor out the parts of `_bfd_mips_elf_merge_private_bfd_data' responsible for ELF file header flag compatibility checks to `mips_elf_merge_obj_e_flags'. As a side effect remove a premature return point from `_bfd_mips_elf_merge_private_bfd_data'. No functional change otherwise. bfd/ * elfxx-mips.c (mips_elf_merge_obj_e_flags): New function, factored out from... (_bfd_mips_elf_merge_private_bfd_data): ... here.
2016-01-04MIPS/BFD: Fold the handling of input MIPS ABI flags togetherMaciej W. Rozycki2-16/+19
Fold the handling of input MIPS ABI flags in private BFD data merging together, moving the attribute check afterwards, and consequently making input vs output compatibility checks only start once all input ABI flag data has been gathered, checked for inconsistencies and put in order. Consequently also address the issue of input ABI flag inconsistencies being masked by a failing attribute check, which currently makes `_bfd_mips_elf_merge_private_bfd_data' exit prematurely and therefore prevent input ABI flag inconsistencies from being reported. Such inconsistencies need to be reported as they may be the very cause of an attribute check failure. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Fold the handling of input MIPS ABI flags together.
2016-01-04MIPS/BFD: Suppress attribute checks for null inputMaciej W. Rozycki2-15/+20
We currently special-case the handling of attribute checks on input objects and make them even before we check a given input object actually contains any sections. This does not add value as empty objects do not cause a compatibility concern and we already make this observation for other properties such as ELF file header flags. Moreover the attributes themselves are stored in a `.gnu.attributes' section so the absence of any section (except from a few special cases) implies there have been no attributes provided either. Therefore it is safe to move the attribute checks later on, after the null-section check has been made. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Suppress attribute checks for null input.
2016-01-04MIPS/BFD: Use local pointers to target data in private data mergeMaciej W. Rozycki2-32/+34
Use local pointers to target data to reduce the amount of indirection and improve the readability of `_bfd_mips_elf_merge_private_bfd_data'. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Use local pointers to target data.
2016-01-04MIPS/BFD: Correct an FP ABI warningMaciej W. Rozycki2-1/+6
Correct a warning produced on any FP ABI mismatch observed. Unlike the other settings, which in the presence of `.MIPS.abiflags' are duplicated in the `e_flags' member of the ELF file header, information on the FP ABI in use is duplicated in `.gnu.attributes' rather than in the former place. Update the warning message accordingly. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Correct an FP ABI warning.
2016-01-04sim: parse_args: polish getopt error messageMike Frysinger5-3/+12
The cris sim hit a few failures after the recent getopt logic, and the expected output showed a few ways we can improve things to better match other utils.
2016-01-04sim: punt x86-specific bswap logicMike Frysinger68-699/+187
The compiler/C library should produce reasonable code for htonl/ntohl, and at least glibc tries pretty hard to always produce good code for them. This logic only had support for 32-bit x86 systems anymore, and it's unlikely people were even opting into this, so drop it all.
2016-01-04sim: d10v: gut endian logicMike Frysinger2-77/+5
The compiler should produce reasonable code here in general, so punt the various arch checks and bswap defines. This code will eventually go away entirely when we convert it to the common memory code.
2016-01-04btrace: do not return out of TRY/CATCHMarkus Metzger6-4/+139
In btrace_pt_readmem_callback, we read memory inside TRY/CATCH and return in case of an error return value. This corrupts the cleanup chain, which eventually results in a SEGV when doing or discarding cleanups later on. gdb/ * btrace.c (btrace_pt_readmem_callback): Do not return in TRY/CATCH. testsuite/ * gdb.btrace/dlopen.exp: New. * gdb.btrace/dlopen.c: New. * gdb.btrace/dlopen-dso.c: New.
2016-01-03sim: parse_args: display getopt error ourselvesMike Frysinger44-64/+138
Fix a long standing todo where we let getopt write directly to stderr when an invalid option is passed. Use the sim io funcs instead as they go through the filtered callbacks that gdb wants.

2016-01-03sim: drop host endian configure optionMike Frysinger96-5871/+6648
The --enable-sim-hostendian flag was purely so people had an escape route for when cross-compiling. This is because historically, AC_C_BIGENDIAN did not work in those cases. That was fixed a while ago though, so we can require that macro everywhere now and simplify a good bit of code.
2016-01-03sim: convert to bfd_endianMike Frysinger90-699/+712
Rather than re-invent endian defines, as well as maintain our own list of OS & arch-specific includes, punt all that logic in favor of the bfd ones already set up and maintained elsewhere. We already rely on the bfd library, so leveraging the endian aspect should be fine.

The iq2000/m32r/sh64 option parsing logic appears to have always been dead. At least iq2000/sh64 are simply copy & paste rot from m32r. The lm32 option parsing hack here hasn't been needed for a while -- this was fixed back in commit 11409fac6b95d71a92848a4499b02d60a4f4c5bb in the common code.
2016-01-02sim: delete dead current_state globalsMike Frysinger19-86/+42
The global current_state handle to the current simulator state is a design idea that was half implemented, but never really cleaned up. The point was to have a global variable pointing to the state so that funcs could more quickly & easily access the state anywhere. We've instead moved in the direction of passing state around everywhere and don't have any intention of moving back. I also can't find any references to gdb using this variable, or to cgen related "dump_regs" functions, both of which were used in the comments related to this code.

2016-01-02sim: ppc: do not exit when parsing args w/gdbMike Frysinger5-22/+50
When connecting to the simulator in gdb, we don't want it to exit on us when we pass down unknown/invalid/help/etc... options. Plumb down the kind argument so we can handle both gdb & psim interfaces.
