2015-06-25Use strtab with GC and suffix merging for .strtabH.J. Lu11-174/+324

2015-06-25Correctly notice empty sysroots in solib_find_1Gary Benson2-9/+14
Some parts of solib_find_1 should only operate if the sysroot is nonempty after processing, but the logic that checked this happened before trailing slashes were stripped so empty but non-NULL sysroots were possible.

When converting "mov foo@GOTPCREL(%rip), %reg" to "lea foo(%rip), %reg" with R_X86_64_PC32 relocation, it may overflow if the target section is more than 2GB away.

The default gdb sysroot now sets itself to "target:". This works for most remote targets, but when using the simulator, this causes problems as the sim will attempt to search for that path. Update the remote-sim logic to skip this leading prefix when it is found so that the sysroot isn't passed in as an invalid value.

2015-06-23Fix GDBHISTSIZE test failure on i686Patrick Palka2-1/+14
The test test_histsize_history_setting "99999999999999999999999999999999999" "unlimited" was failing on i686 because the condition in init_history() for determining whether to map a large GDBHISTSIZE value to infinity was long var = strtol (tmpenv); if (var > INT_MAX) history_size = unlimited; but this condition is never true on i686 because INT_MAX == LONG_MAX. So in order to properly map large out-of-range values of GDBHISTSIZE to infinity on targets where LONG_MAX > INT_MAX as well as on i686, we have to instead change the above condition to if (var > INT_MAX || (var == INT_MAX && errno == ERANGE)) history_size = unlimited; gdb/ChangeLog: * top.c (init_history): Look at errno after calling strtol to properly map large GDBHISTSIZE values to infinity.

2015-06-23Convert have_ptrace_getregset to a tri-state booleanYao Qi7-29/+53
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have some conditions like "if (have_ptrace_getregset)", which is not correct. I'll explain why it is not correct in the following example. This fix to this problem to replace the test (have_ptrace_getregset) to test (have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc. However Doug thinks it hinders readability https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide to add a new enum tribool and change have_ptrace_getregset to it, in order to make these tests more readable. have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in $ARCH_linux_read_description according to the capability of the kernel. However, it is possible that have_ptrace_getregset is used before it is set to 0 or 1, which means it is still -1. This is shown below.

2015-06-22PPC sync instruction accepts invalid and incompatible operandsPeter Bergner5-17/+57
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 commit is to add comments on using this board file and the requirements on localhost. gdb/testsuite: 2015-06-22 Yao Qi <yao.qi@linaro.org> * boards/remote-gdbserver-on-localhost.exp: Add comments.
2015-06-22Don't skip hw breakpoint/watchpoint tests for aarch64 targetYao Qi2-1/+9
This patch is to let skip_hw_breakpoint_tests and skip_hw_watchpoint_tests return 0 for aarch64 target, since aarch64 has HW watchpoint and breakpoint registers. With this patch applied, about 1560 watchpoint/breakpoint related tests become enabled on aarch64-linux native testing. gdb/testsuite: 2015-06-22 Yao Qi <yao.qi@linaro.org> * lib/gdb.exp (skip_hw_breakpoint_tests): Return 0 for target aarch64*-*-*. (skip_hw_watchpoint_tests): Likewise.

2015-06-21sim: common: add basic model assertMike Frysinger2-0/+5
If the configured in default doesn't match a known value, throw an assertion failure rather than segfaulting deeper down.
2015-06-21sim: common: use standard intXX_t types for signedXXMike Frysinger2-82/+27
Let's assume that the system supports the POSIX int8/16/32/64_t types as this collapses the logic significantly.
2015-06-21sim: common: standardize multiple include definesMike Frysinger6-13/+26
We use SIM_xxx_H in most headers, so convert _SIM_xxx_H_ over to it.
2015-06-21Don't use $< in MakefilesAlan Modra3-44/+49
$< is a GNU make feature. * Makefile.am: Expand $<. * Makefile.in: Regenerate.

2015-06-19Allow for optional operands with non-zero default values.Peter Bergner11-32/+75
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. (ppc_optional_operand_value): New inline function. opcodes/ * ppc-dis.h (skip_optional_operands): Use ppc_optional_operand_value. * ppc-opc.c (FXM4): Add non-zero optional value. (TBR): Likewise. (SXL): Likewise. (insert_fxm): Handle new default operand value. (extract_fxm): Likewise. (insert_tbr): Likewise. (extract_tbr): Likewise. gas/ * config/tc-ppc.c (md_assemble): Use ppc_optional_operand_value. Allow for optional operands without insert functions. gas/testsuite/ * gas/ppc/power8.d: Fixup rfebb test results. * gas/ppc/a2.s: Fix invalid mfcr test. * gas/ppc/a2.d: Likewise.
