Allow for optional operands with non-zero default values. ISA 2.07 (ie, POWER8) added the rfebb instruction which takes one operand with the value of either a 0 or 1. It also defines an extended mnemonic with no operands (ie, "rfebb") that is supposed to be equivalent to "rfebb 1". I implemented rfebb's lone operand with PPC_OPERAND_OPTIONAL, but the problem is, optional operands that are ommitted always default to the value 0, which is wrong in this case. I have added support for allowing non-zero default values by adding an additional flag PPC_OPERAND_OPTIONAL_VALUE that specifies that the default operand value to be used is stored in the SHIFT field of the operand field immediately following this one. This fixes the rfebb issue. I also fixed the mftb and mfcr instructions so they use the same mechanism. This allows us to flag invalid uses of mfcr where we explicitly pass in a zero FXM value, like the use in a2.[sd]. include/opcode/ * ppc.h (PPC_OPERAND_OPTIONAL_VALUE): New.

gas: section name substitution sequence This patch adds the ability to automatically construct a section name based on the prior section. When gas is invoked with --sectname-subst, the occurrence of %S in a section name will be substituted by the name of the current section. For example: .macro exception_code .pushsection %S.exception [exception code here] .popsection .endm .text [code] exception_code [...] .section .init [init code] exception_code [...] The first and second exception_code invocations create the .text.exception and the .init.exception sections respectively. This is useful e.g. to discriminate between anciliary sections that are tied to .init code and can be discarded at run time when initialization is over vs anciliary sections tied to .text sections that need to stay resident. * as.c (show_usage): Document --sectname-subst.

gas: Don't use frag_align but use plain padding to align .debug_aranges. out_debug_aranges uses frag_align to make sure the addresses start out aligned. Using frag_align will call frag_var[_init], which will end up calling TC_FRAG_INIT. On arm and aarch64 TC_FRAG_INIT will generate a $d mapping symbol for the .debug_aranges to show that at that point a sequence of data items starts. Such a symbol pointing into a non-allocated debug section will confuse eu-strip -g. And it seems inefficient and wrong in general to have additional mapping symbols for debug sections, which won't contain actual code in the first place. Just keep track of the aranges header size and use plain padding to align the addresses which avoids generating any mapping symbols on aarch64 and arm. Includes a testcase for aarch64 that PASS with this patch and shows the extra $d mapping symbol in .debug_aranges before. gas/ChangeLog * dwarf2dbg.c (out_header): Document EXPR->X_add_number value, out_debug_aranges depends on it.

Support AMD64/Intel ISAs in assembler/disassembler AMD64 spec and Intel64 spec differ in direct unconditional branches in 64-bit mode. AMD64 supports direct unconditional branches with 16-bit offset via the data size prefix, which truncates RIP to 16 bits, while the data size prefix is ignored by Intel64. This patch adds -mamd64/-mintel64 option to x86-64 assembler and -Mamd64/-Mintel64 option to x86-64 disassembler. The most permissive ISA, which is AMD64, is the default. GDB can add an option, similar to (gdb) help set disassembly-flavor Set the disassembly flavor.

Add -mshared option to x86 ELF assembler This patch adds -mshared option to x86 ELF assembler. By default, assembler will optimize out non-PLT relocations against defined non-weak global branch targets with default visibility. The -mshared option tells the assembler to generate code which may go into a shared library where all non-weak global branch targets with default visibility can be preempted. The resulting code is slightly bigger. This option only affects the handling of branch instructions.

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.

Fix msp430 build with gcc-5 gcc-5 correctly complains "loop exit may only be reached after undefined behavior".

gas: allow labeling of CFI instructions 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.

gas/avr: Prevent incorrect overflow errors for diff fixups. 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.
