2015-02-26Adding ld_literal_type.Marcus Shawcroft2-5/+42
Extend the address modifier parsing to distinguish between the modifers used in LDR literal and LDR register offset address modes. The current parser incorrectly accepts the :got: modifier on a register offset instruction resulting in silent corruption of the output binary.
2015-02-26Adding test case for abuse of :got: in offset loadMarcus Shawcroft3-0/+7
The :got: modifier is not meaningful in a register offset load store instruction and should result in a diagnostic.
2015-02-26Adding adr_type and prevent adr :got:Marcus Shawcroft2-3/+53
The current implementation of the :got: assembler modifier does not distinguish the ADR and ADRP instruction. The :got: modifier does not make sense on and ADR instruction and should be error'd rather than the current behavior of applying an inappropriate relocation to the output and scrambling the underlying instruction silently.
2015-02-26Add test case for ADR :got:fooMarcus Shawcroft3-0/+7
The modifier :got: does not make sense on an ADR instruction. Add a test case to ensure we gripe.

2015-02-25avr/gas: Write out data to track .org/.align usage.Andrew Burgess3-0/+375
Adds support to the assembler to write out data for tracking the use of .org and .align directives. This data is collected within the assembler and written out to a section ".avr.prop" (if there's anything to write out). This patch does not add any tests. The next patch in this series will add a better mechanism for visualising the contents of .avr.prop which will make writing tests much easier. This patch also does not make any use of this collected data, that will also come along in a later patch; the intended consumer is the linker, during linker relaxation this information will be used to ensure that the .org and .align directives are honoured. bfd/ChangeLog: * elf32-avr.h (AVR_PROPERTY_RECORD_SECTION_NAME): Define.

2015-02-05Fix msp430 build with gcc-5Alan Modra2-2/+7
gcc-5 correctly complains "loop exit may only be reached after undefined behavior".

2015-01-12gas: allow labeling of CFI instructionsJan Beulich9-2/+130
When runtime patching code (like e.g. done by the Linux kernel) there may be cases where the set of stack frame alterations differs between unpatched and patched code. Consequently the corresponding unwind data needs patching too. Locating the right places within an FDE, however, is rather cumbersome without a way to insert labels in the resulting section. Hence this patch introduces a new directive, .cfi_label. Note that with the way CFI data gets emitted currently (at the end of the assembly process) this can't support local FB- and dollar-labels. gas/ 2015-01-12 Jan Beulich <jbeulich@suse.com> * gas/dw2gencfi.c (cfi_add_label, dot_cfi_label): New.

2015-01-10gas/avr: Prevent incorrect overflow errors for diff fixups.Andrew Burgess5-0/+42
When fixups are converted to a difference type within md_apply_fix, we previously left the contents of VALP (the value that was initially computed within write.c:fixup_segment) unchanged. This is harmless, except that this value is used within write.c:fixup_segment once we return from md_apply_fix to perform an overflow check. In some cases, the value computed in write.c:fixup_segment is so wrong that an overflow error can be triggered. These errors are incorrect. This patch avoids the overflow errors by adjusting the value in write.c:fixup_segment using the VALP pointer in md_apply_fix. A test for this issue is included. gas/ChangeLog: * config/tc-avr.c (md_apply_fix): Update the contents of VALP for diff fixups. gas/testsuite/ChangeLog: * gas/avr/large-debug-line-table.d: New file. * gas/avr/large-debug-line-table.s: New file.

2015-01-07arm: fix extension feature disablingJan Beulich2-15/+33
Using e.g. .arch_extension simd .arch_extension nocrypto so far results in SIMD support getting disabled, which I can't see being the purpose of the "no"-prefixed variants of architecture extension specifications. Of course it is questionable whether the current, counter intuitive behavior needs to be retained, and the new behavior perhaps be made work through e.g. a newly recognized "no-" prefix. gas/ 2015-01-07 Jan Beulich <jbeulich@suse.com> * gas/config/tc-arm.c (struct arm_option_extension_value_table): Split field "value" into fields "merge_value" and "clear_value".

2014-12-24AVR: Assembler now prepares for linker relaxation by default.Andrew Burgess6-11/+40
Have the assembler prepare for linker relaxation by default. This means that users will be able to make use of linker relaxation without having to adjust the assembler flags, this can make life easier when compiling libraries. Having this on by default in the assembler should make no difference to the assembler code produced, however, some of the debug information will be slightly less compressed. A few tests needed to be updated as a result of this change as they relied on linker relaxation support being off by default. I've tightened up the definition of which sections can be relaxed on AVR as part of this commit, the assembler used to think that all non-debugging sections could be relaxed, when in reality only code sections can be relaxed for AVR. The previous definition was not dangerous, just over cautious. The new tighter definition allows an extra test (gas/testsuite/gas/all/forward.d) to continue to pass. gas/ChangeLog: * config/tc-avr.c (struct avr_opt_s): Change link_relax to no_link_relax, extend comment.

2014-12-23AVR: Only set link-relax elf flag when appropriate.Andrew Burgess7-1/+48
The AVR target uses a bit in the elf header flags to indicate if the object was assembled ready for linker relaxation. Previously this flag was always set, even when the object was not assembled ready for linker relaxation. This patch moves setting of the flag into the assembler, and sets it only when the assembler is preparing the file for linker relaxation. bfd/ChangeLog: * elf32-avr.c (bfd_elf_avr_final_write_processing): Don't set EF_AVR_LINKRELAX_PREPARED unconditionally. gas/ChangeLog: * config/tc-avr.c: Add include for elf/avr.h.
