2016-04-05ld/arc: Fix linker for big-endian arc targetsAndrew Burgess28-93/+65
This aims to bring the linker for big-endian arc targets into line with the linker for (the default) little endian arc targets. The bulk of the changes are to extend the target pattern in the test files from 'arc-*...' to 'arc*-*...' and so match both big and little endian arc targets. In the ld/emulparams/ directory the existing scripts checked for a variable ARC_ENDIAN to switch between big and little endian targets, however, this variable is never set up. So, a new script snippet is introduced which sets up ARC_ENDIAN based on the value of target, this snippet is then included from all of the existing arc scripts. The existing big-endian variants of all the scripts, which existed, but were never used, are deleted in this commit. ld/ChangeLog: * emulparams/arc-endianness.sh: New file. * emulparams/arcebelf.sh: Deleted. * emulparams/arcebelf_prof.sh: Deleted. * emulparams/arceblinux.sh: Deleted. * emulparams/arceblinux_prof.sh: Deleted. * emulparams/arcelf.sh: Include arc-endinness.sh. * emulparams/arcelf_prof.sh: Include arc-endinness.sh. * emulparams/arclinux.sh: Include arc-endinness.sh. * emulparams/arclinux_prof.sh: Include arc-endinness.sh. * emulparams/arcv2elf.sh: Include arc-endinness.sh. * emulparams/arcv2elfx.sh: Include arc-endinness.sh. * testsuite/ld-elf/compressed1d.d: Update pattern for big and little endian arc targets. * testsuite/ld-elf/eh-frame-hdr.d: Likewise. * testsuite/ld-elf/group1.d: Likewise. * testsuite/ld-elf/group3b.d: Likewise. * testsuite/ld-elf/group8a.d: Likewise. * testsuite/ld-elf/group8b.d: Likewise. * testsuite/ld-elf/group9a.d: Likewise. * testsuite/ld-elf/group9b.d: Likewise. * testsuite/ld-elf/linkonce2.d: Likewise. * testsuite/ld-elf/pr12851.d: Likewise. * testsuite/ld-elf/pr12975.d: Likewise. * testsuite/ld-elf/pr13177.d: Likewise. * testsuite/ld-elf/pr13195.d: Likewise. * testsuite/ld-elf/pr17615.d: Likewise. * testsuite/ld-elf/pr19162.d: Likewise. * testsuite/ld-elf/sec64k.exp: Likewise. * testsuite/lib/ld-lib.exp: Likewise.

2016-04-05Make ftrace tests work with remote targetsSimon Marchi7-31/+51
When we build a shared library for testing, it is built differently whether it is meant for the local system or a remote one. When it is for the local system, the library is built with no SONAME. So when the executable is built, roughly in this way: $ gcc testfile.c /path/to/library.so the executable will contain an absolute reference to the library. For example: $ readelf -a testsuite/gdb.python/py-shared | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [/home/emaisin/build/binutils-gdb/gdb/testsuite/gdb.python/py-shared-sl.sl] When testing is done remotely, the absolute path obviously doesn't work. Therefore, we build the library with an SONAME: $ readelf -a testsuite/gdb.python/py-shared-sl.sl | grep SONAME 0x000000000000000e (SONAME) Library soname: [py-shared-sl.sl] which ends up in the executable's NEEDED field: $ readelf -a testsuite/gdb.python/py-shared | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [py-shared-sl.sl] The executable and the library are then uploaded side-by-side on the remote system. To allow the dynamic linker to find the shared library, we have to add the special RPATH value $ORIGIN, which tells it to search in the executable's directory: $ readelf -a testsuite/gdb.python/py-shared | grep ORIGIN 0x000000000000000f (RPATH) Library rpath: [$ORIGIN] The problem with the IPA library is that it doesn't have an SONAME, making it very difficult to do testing on a remote board. When a test executable is linked with it, it contains an absolute reference to the library path. Therefore, unless the paths on the target are the same as on the build system, it won't work. To make it possible for tests using the IPA library to run test on remote boards, I suggest adding an SONAME to libinproctrace.so. I don't think it should be a big problem for users. All the libraries installed on my system have an SONAME, so it should be fine if libinproctrace.so does too. As a consequence, native testing does not work anymore, since executables do not contain the absolute path to the library anymore. To keep them working, we can have gdb_load_shlibs copy the library to the test directory when testing natively. That's done by modifying gdb_load_shlibs. We also have to add RPATH=$ORIGIN to executables, even when testing natively. I think it's a good change in general, as it reduces the differences between testing a native and a remote target. To further reduce those differences, we can also always build test shared libraries with an SONAME. ftrace.exp and ftrace-lock.exp need to be modified slightly. The code checks that the IPA library is loaded using the absolute path on the build machine. That obviously doesn't work if the test is done remotely, as the path will be different. I changed the tests to only search for the library basename (e.g. libinproctrace.so). gdb/gdbserver/ChangeLog: * Makefile.in ($(IPA_LIB)): Set SONAME of the IPA lib. gdb/testsuite/ChangeLog: * gdb.trace/ftrace-lock.exp: Check for IPA basename instead of absolute. * gdb.trace/ftrace.exp: Likewise. * lib/gdb.exp (gdb_compile): Set rpath $ORIGIN for non-remote targets as well.

2016-04-05Improve gdb_remote_download, remove gdb_downloadSimon Marchi6-38/+51
This patch removes gdb_download in favor of gdb_remote_download, since they are very close in functionality. Also, in preparation for the following patch about shared library handling during tests, it improves gdb_remote_download so that it uses standard_output_file for any destination board that is local, not only host. If the destination board is remote, gdb_remote_download will use the standard remote_download from DejaGnu, resulting in the file being transferred on the remote system. If the destination is local, gdb_remote_download will copy the file to the standard test directory (found using standard_output_file). Tcl's file copy seems to handle gracefully cases where the source file is the same as the destination, so I don't think it's necessary to check for that case ourselves, as a previous version of the patch did. I'd prefer to keep the name gdb_download instead of gdb_remote_download, since I don't like the fact that gdb_remote_download implies that the destination is remote, when it's not always the case. However, gdb_remote_download is used at many more places than gdb_download, so it's easier to reuse that. Also, since it's a wrapper around DejaGnu's remote_download, it might be better to keep that name. I don't know. I ran the testsuite native, with native-gdbserver and with a remote gdbserver, and didn't see any related failure. gdb/testsuite/ChangeLog: * gdb.base/jit-so.exp: Use gdb_remote_download instead of gdb_download. Use it even if the target is not remote. * gdb.base/jit.exp (compile_jit_test): Likewise. * lib/gdb.exp (gdb_remote_download): Copy files to the standard output directory if the destination board is local, otherwise use the standard remote_download from DejaGnu.

2016-04-05ELF/LD: Avoid producing hidden and internal dynamic symbolsMaciej W. Rozycki19-11/+173
Always turn hidden and internal symbols which have a dynamic index into local ones. This is required by the the ELF gABI[1]: "A hidden symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." "An internal symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." The ELF linker usually respects this requirement, however in the case where a dynamic symbol has been preallocated due to a reference of the default export class aka visibility from the object being linked, and then merged with a hidden or internal symbol definition from within the same object, then the original export class is carried over to the output dynamic symbol table, because while merging the generic ELF linker only converts affected dynamic symbols to local when they are defined or referenced by the object being linked and a dynamic object involved in the link both at a time. The dynamic symbol produced confuses then the dynamic loader at the run time -- the hidden or internal export class is ignored and the symbol follows preemption rules as with the default export class. In the MIPS target it happens when `mips_elf_record_global_got_symbol' creates a dynamic symbol when a call relocation is encountered. Additionally if the undefined symbol referred by such a relocation does specify the intended export class, then a local dynamic symbol is created instead, which is harmless and allowed, but useless. Normally no local dynamic symbols are created, except for a single dummy one at the beginning. Correct the problem by removing the extra check for a dynamic symbol being defined or referenced by the object being linked and a dynamic object involved in the link both at a time. The test cases included cover the internal and hidden symbol cases, as well as a protected symbol for a reference, the handling of which is unchanged by this fix. Both cases described above are covered, that is where an internal or hidden dynamic symbol is produced and where a local one is. NB this change affects CRIS results where some symbols in the static table produced in a final link are now converted from STV_HIDDEN to STB_LOCAL. This happens whenever the `elf_backend_hide_symbol' handler is called, so the affected symbols must have been chosen for entering into the dynamic symbol table, except in these test cases no such symbol table is produced. In fully linked binaries the static symbol table is only used for debugging though, so such a change is fine.

2016-04-01gdb: allow enumeration constants as second operand of BINOP_REPEATArtemiy Volkov4-1/+18
This patch adds support for TYPE_CODE_ENUM values to be supplied as right-hand side operand of the BINOP_REPEAT (@) operator.

This isn't perfect in checking whether libraries will be loaded since elf_link_add_object_symbols doesn't recurse down DT_NEEDED links. (That happens later in ld/emultempl/elf32.em after_open.)

2016-03-31Fix PR gdb/19858: GDB doesn't register the JIT libraries on attachYichao Yu2-2/+20
Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html GDB currently fails to fetch the list of already-registered JIT modules on attach. Nothing is calling jit_inferior_init, which is what is responsible for walking the JIT object list at init time. Despite the misleading naming, jit_inferior_created_hook -> jit_inferior_init is only called when the inferior execs. This regressed with the fix for PR gdb/13431 (03bef283c2d3): https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which removed the inferior_created (jit_inferior_created_observer) observer. Adding an inferior_created observer back fixes the issue. In turn, this exposes a bug in jit_breakpoint_re_set_internal as well, which is returning the wrong result when we already have the breakpoint at the right address. gdb/ChangeLog: 2016-03-31 Yichao Yu <yyc1992@gmail.com> PR gdb/19858 * jit.c (jit_breakpoint_re_set_internal): Return 0 if we already got the breakpoint at the right address.
