MIPS16/GAS: Fix delay slot filling across frags

addiu $4, $4, 4

with the generation of a listing file enabled, e.g.:

$ as -mips16 -O2 -aln=test.lst

The cause of the problem is the lack of support for moving instructions
across frags in MIPS16 jump swapping, which triggers more easily with
listing enabled as in that case every instruction gets placed in its own
frag.  It would trigger even with listing disabled though if the
instruction to swap a MIPS16 jump with was unfortunately enough placed
as last in a frag that became full.

This scenario is already handled correctly with branch swapping in
regular MIPS and microMIPS code, so reuse it for MIPS16 code as well,
and now that all MIPS16 handling has become the same as the regular MIPS
and microMIPS cases remove MIPS16 special casing altogether.

This effectively complements:

When testing with gdbserver, gdb_exit is overridden with a special

The problem is that the commit mentioned above made
gdb_exit/mi_gdb_exit clear inferior_spawn_id too, and clearing a
non-existing variable is a tcl error.

8 years agogold: Support x86-64 TLS code sequences without PLT

gold: Support x86-64 TLS code sequences without PLT

There are extensions to x86-64 psABI:

https://groups.google.com/forum/#!topic/x86-64-abi/de5_KnLHxtI

to call tls_get_addr via GOT:

call *__tls_get_addr@GOTPCREL(%rip)

Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.

For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call.  For local dynamic model, we
simply use 5-byte indirect call.

TLS linker optimization is updated to recognize new instruction
patterns.  For local dynamic model to local exec model transition, we
generate 4 0x66 prefixes, instead of 3, before mov instruction in 64-bit
and generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit.

8 years ago[AArch64] Make register indices be full 64-bit values
Richard Sandiford [Tue, 28 Jun 2016 08:21:04 +0000 (09:21 +0100)]
[AArch64] Make register indices be full 64-bit values

aarch64_opnd_info used bitfields to hold vector element indices,
but values were stored into those bitfields before their ranges had
been checked.  This meant large invalid indices could be silently
truncated to smaller valid indices.

The two obvious fixes were to do the range checking earlier or use
a full 64-bit field for the index.  I went for the latter for two
reasons:

      - Doing the range checking in operand_general_constraint_met_p
        seems structurally cleaner than doing it while parsing.

      - The bitfields didn't really buy us anything.  The imm field
        of the union is already 128 bits, so we can use a full int64_t
        index without growing the structure.

The patch also adds missing range checks for the elements in a register
list index.

8 years agoAdd support for catching system calls to native FreeBSD targets.
John Baldwin [Mon, 13 Jun 2016 04:24:42 +0000 (21:24 -0700)]
Add support for catching system calls to native FreeBSD targets.

All platforms on FreeBSD use a shared system call table, so use a
single XML file to describe the system calls available on each FreeBSD
platform.

Recent versions of FreeBSD include the identifier of the current
system call when reporting a system call entry or exit event in the
ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait.  As
such, FreeBSD native targets do not use the gdbarch method to fetch
the system call code.  In addition, FreeBSD register sets fetched via
ptrace do not include an equivalent of 'orig_rax' (on amd64 for
example), so the system call code cannot be extracted from the
available registers during a system call exit.  However, GDB assumes
that system call catch points are not supported if the gdbarch method
is not present.  As a workaround, FreeBSD ABIs install a dummy gdbarch
method that throws an internal_error if it is ever invoked.

Different platforms have different meanings for auxiliary vector

fprint_target_auxv into a new default_print_auxv_entry function.
default_print_auxv_entry chooses an appropriate format and description

This is because BFD_SUPPORTS_PLUGINS is always defined. It is its value
that determines whether plugin support is enabled or not.

bfd/ChangeLog:

        * elflink.c: Check the value of BFD_SUPPORTS_PLUGINS rather
        than its existance.

Alan Modra [Thu, 23 Jun 2016 12:41:57 +0000 (22:11 +0930)]
MIPS objcopy --rename-section fix

Some MIPS targets use a named section symbol rather than a symbol with
no name as is used with most ELF targets.  When renaming sections, the
named section symbol needs to be renamed too.

Rather than fix this bug, I'd originally intended to just correct the
xfail added recently for update-1.o vs update4.o in update-section.exp,
using the same set of targets for the localize-hidden-1 mips xfail.
I'd extracted that target test into a new function, is_bad_symtab.  It
turns out to be useful in readelf.exp too.

bfd/
* config.bfd: Delete mips vxworks patterns matched earlier.
Combine mips*-*-none with mips*-*-elf*.
binutils/
* objcopy.c (find_section_rename): Forward declare.  Remove
ibfd and sec_ptr param.  Add old_name param.  Allow for NULL
returned_flags.  Move read of section name and flags to..
(setup_section): ..here.  Update find_section_rename call.
(filter_symbols): Rename section symbols for renamed sections.
(copy_object): Call filter_symbols when renamed sections.
* testsuite/lib/binutils-common.exp (is_bad_symtab): New.
* testsuite/binutils-all/update-section.exp: Revert 96037eb0
mips xfail.
* testsuite/binutils-all/objcopy.exp (copy_executable): Use
is_bad_symtab.
(localize-hidden-1): xfail if is_bad_symtab.
* testsuite/binutils-all/readelf.exp: Use is_bad_symtab to select
between mips/tmips.

This target doesn't build, due to a missing gas/config/te-obsd.h file.
