2016-04-20Check R_386_NONE/R_X86_64_NONE in eh6.dH.J. Lu1-0/+6
There is no need for run-time relocation when converting pointers in .eh_frame section to DW_EH_PE_pcrel encoding.

2016-04-07ld/arc: Make little endian default choice for linker scriptsAndrew Burgess1-0/+4
When building with --enable-targets=all the target string is not set to something that matches the pattern arc*-*, and so the script used to decide if we should build big or little endian linker script currently exits with an error. This commit makes little endian linker script be the default, which will be used when building for all targets, this matches the behaviour from before I made the endianness switchable, when we only ever built little endian linker scripts anyway. ld/ChangeLog: * emulparams/arc-endianness.sh: Make little endian default choice.
2016-04-07Fix typo in name of MSP430 attribute section.Nick Clifton1-0/+6
2016-04-05ld/arc: Fix linker for big-endian arc targetsAndrew Burgess1-0/+32
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.
2016-04-05ELF/LD: Avoid producing hidden and internal dynamic symbolsMaciej W. Rozycki1-0/+20
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.

2016-03-30ld/testing: Fix error and warning checks in run_dump_testAndrew Burgess1-0/+7
The options warning_output and error_output to the run_dump_test function were incorrectly checking the return value from the regexp_diff function, and so, as a result failing tests were showing as a pass. Fixed in this commit. ld/ChangeLog: * testsuite/lib/ld-lib.exp (run_dump_test): Fix check of return value from regexp_diff. * testsuite/ld-elf/orphan-5.l: Fix expected output. * testsuite/ld-elf/orphan-6.l: Likewise.

2016-03-09Fix v850 bfd arch info printable namesPedro Alves1-0/+5
Currently, it's not possible to manually set some of the v850 archs in gdb: (gdb) set architecture v850<TAB> v850 (using old gcc ABI) v850-rh850 v850e v850e (using old gcc ABI) v850e1 [...] (gdb) set architecture v850 (using old gcc ABI) Ambiguous item "v850 (using old gcc ABI)". The problem is that "set architecture" is a GDB "enum command", and GDB only considers an enum value to be the string up until the first space. So writing "v850 (using old gcc ABI)" is the same as writing "v850", and then that's not an unambiguous arch printable name prefix. v850 is actually the only arch that has spaces in its printable name. One can conveniently see that with e.g.: (gdb) set max-completions unlimited (gdb) complete set architecture ... Rather than hack GDB into accepting this somehow, make v850 arch printable names more like the printable names of the other archs, and put the abi variant in the "machine" part, after a ':'. We now get: (gdb) set architecture v850<TAB> v850:old-gcc-abi v850:rh850 v850e v850e1 v850e1:old-gcc-abi v850e2 v850e2:old-gcc-abi [...] And now "set architecture v850:old-gcc-abi" works as expected. I ran the binutils/gas/ld testsuites, and found no regressions. I don't have a cross compiler handy, but I ran the gdb tests anyway, which covers at least some snoke testing. I think that the OUTPUT_ARCH in ld/scripttempl/v850.sc may have got broken with the previous 2012 change, since I hacked v850_rh850.sc to output "v850" and ld failed to grok it. I think it only works if the old GCC ABI is the configured v850 default ABI. That's now fixed by changing to use explicit v850:old-gcc-abi. Also, this actually "fixes" an existing GDB test, which isn't likewise expecting spaces in arch names, when GDB is configured for --target=v850: (gdb) FAIL: gdb.xml/tdesc-arch.exp: read valid architectures bfd/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * cpu-v850.c (N): Append ":old-gcc-abi" instead of " (using old gcc ABI)" to printable name. * cpu-v850_rh850.c (bfd_v850_rh850_arch): Use "v850:rh850" instead of "v850-rh850" as printable name. ld/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * scripttempl/v850.sc: Use "v850:old-gcc-abi" as OUTPUT_ARCH. * scripttempl/v850_rh850.sc: Use "v850:rh850" as OUTPUT_ARCH.
