2017-08-31bfd_close_all_done calling _close_and_cleanupAlan Modra2-15/+10
elf64_vms_close_and_cleanup calls bfd_get_size, which calls iovec->bstat. cache_bstat ends up adding the bfd to the cache lru list, negating the bfd_cache_close call in bfd_close_all_done. So there is a dangling pointer into the freed and then reused bfd. Thus, bfd_cache_close must be called after _close_and_cleanup, or better, via iovec->bclose. PR binutils/22032 * opncls.c (bfd_close_all_done): Don't call bfd_cache_close before _close_and_cleanup. Call iovec->bclose after. (bfd_close): Remove code common to, and call, bfd_close_all_done.

2017-08-29Look for FIR in the last FreeBSD/mips floating-point register.John Baldwin3-14/+39
FreeBSD/mips kernels were recently changed to include the floating point implementation revision register in the floating point register set exported in process cores and via ptrace() (r318067). This change will first ship in FreeBSD 12.0 when it is eventually released. The space used to hold FIR was previously reserved in 'struct fpreg' as a zero-filled dummy for padding, so 'struct fpreg' has not changed in size. Since FIR should be non-zero on all MIPS processors supported by FreeBSD, ignore a value of 0 from 'struct fpreg' and only report non-zero values as a valid FIR register. gdb/ChangeLog: * mips-fbsd-nat.c (getfpregs_supplies): Return true for FIR. * mips-fbsd-tdep.c (mips_fbsd_supply_fpregs): Split supply of FSR out of loop and add supply of FIR.

2017-08-29[GOLD] PowerPC tls_get_addr_optimizeAlan Modra8-57/+454
This implements the special __tls_get_addr_opt call stub for powerpc gold that returns __thread variable addresses without actually making a call to __tls_get_addr in most cases. Shared libraries that are loaded at program load time (ie. dlopen is not used) have a known layout for their __thread variables, and thus DTPMOD64/DPTREL64 pairs describing those variables can be set up by ld.so for the __tls_get_addr_opt call stub fast exit. Ref https://sourceware.org/ml/libc-alpha/2015-03/msg00626.html I really, really wish I'd used a differently versioned __tls_get_addr symbol than the base symbol to indicate glibc support for the optimized call, rather than having glibc export __tls_get_addr_opt. A lot of the messing around here, flipping symbols from __tls_get_addr to __tls_get_addr_opt, is caused by that decision. About the only benefit is that a user can see at a glance that their disassembled code is calling __tls_get_addr via the fancy call stub.. Anyway, we need references to __tls_get_addr to seem like they were to __tls_get_addr_opt, and in cases like the tsan interceptor, a definition of __tls_get_addr to seem like one of __tls_get_addr_opt as well. That's the reason for Symbol::clear_in_reg and Symbol_table::clone, and why symbols are substituted in Scan::global and other places dealing with dynamic linking. elfcpp/ * elfcpp.h (DT_PPC_OPT): Define. * powerpc.h (PPC_OPT_TLS): Define. gold/ * options.h (tls_get_addr_optimize): New option. * symtab.h (Symbol::clear_in_reg, clone): New functions.

Commit Command names: make them case sensitive 3d7b173c29900879c9a5958dd6029fd36666e57c made command name lookup case sensitive. However, define_command, used when creating a user-defined command, converts the command name to lowercase, assuming that the command name lookup works in a case insensitive way. This causes user-defined commands with capital letters in their name to only be callable with a lowercase version: (gdb) define Foo Type commands for definition of "Foo". End with a line saying just "end". >print 1 >end (gdb) Foo Undefined command: "Foo". Try "help". (gdb) foo $1 = 1 This patch removes that conversion to lowercase, so that the user can call the command with the same name they provided. gdb/ChangeLog: * cli/cli-script.c (define_command): Don't convert command name to lower case. gdb/testsuite/ChangeLog: * gdb.base/commands.exp (user_defined_command_case_sensitivity): New proc, call it from toplevel.
