2015-07-22gas line buffer handlingAlan Modra2-55/+54
This fixes a segfault when macro definitions end on the last line of a file, and that line isn't properly terminated with a newline. gas used to throw away the last line in cases like this, whereas in other cases gas added the missing newline. So I've also made gas consistently provide a missing newline. PR gas/18687 * input-scrub.c (input_scrub_next_buffer): Rearrange and simplify loop.

2015-07-03Remove ppc860, ppc750cl, ppc7450 insns from common ppc.Alan Modra5-3/+16
Back in the day support for these processors was added, we probably didn't want to waste PPC_OPCODE bits on minor variations. I've had a complaint that disassembly of mfspr/mtspr was wrong for power8. This patch fixes that problem. Note that since -m860/-m850/-m821 are new gas options enabling the mpc8xx specific mfspr/mtspr variants it is possible that this change will break some mpc8xx assembly code. ie. you might need to modify makefiles to pass -m860 to gas. include/opcode/ * ppc.h (PPC_OPCODE_750, PPC_OPCODE_7450, PPC_OPCODE_860): Define. opcodes/ * ppc-opc.c (PPC750, PPC7450, PPC860): Define using PPC_OPCODE_*. * ppc-dis.c (ppc_opts): Add 821, 850 and 860 entries.

2015-06-22PPC sync instruction accepts invalid and incompatible operandsPeter Bergner3-4/+9
ISA 2.07 added a new category called Elemental Memory Barriers that modifies the sync instruction to accept an additional operand ESYNC. Edmar added support for this insruction varient here: https://sourceware.org/ml/binutils/2012-02/msg00221.html Looking at this closer, I see that the insert_ls() function is misnamed (since it's attached to the ESYNC operand, not the LS operand) but more importantly, it is silently modifying the LS operand value behind the users back when the LS operand is either invalid or is incompatible with the new ESYNC operand. The ISA 2.07 doc has an Assembler Note that clearly states that assemblers that support the ESYNC operand should report all invalid uses of LS and ESYNC. This patch changes the assembler to error out on invalid and incompatible operand usage. opcodes/ * ppc-opc.c (insert_ls): Test for invalid LS operands. (insert_esync): New function.

2015-06-19Allow for optional operands with non-zero default values.Peter Bergner6-6/+23
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.

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.

2015-06-15gas: Don't use frag_align but use plain padding to align .debug_aranges.Mark Wielaard5-2/+55
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.
