2017-08-31Implement the ability to set/unset environment variables to GDBserver when ↵Sergio Durigan Junior15-65/+984
starting the inferior This patch implements the ability to set/unset environment variables on the remote target, mimicking what GDB already offers to the user. There are two features present here: user-set and user-unset environment variables. User-set environment variables are only the variables that are explicitly set by the user, using the 'set environment' command. This means that variables that were already present in the environment when starting GDB/GDBserver are not transmitted/considered by this feature. User-unset environment variables are variables that are explicitly unset by the user, using the 'unset environment' command. The idea behind this patch is to store user-set and user-unset environment variables in two separate sets, both part of gdb_environ. Then, when extended_remote_create_inferior is preparing to start the inferior, it will iterate over the two sets and set/unset variables accordingly. Three new packets are introduced: - QEnvironmentHexEncoded, which is used to set environment variables, and contains an hex-encoded string in the format "VAR=VALUE" (VALUE can be empty if the user set a variable with a null value, by doing 'set environment VAR='). - QEnvironmentUnset, which is used to unset environment variables, and contains an hex-encoded string in the format "VAR". - QEnvironmentReset, which is always the first packet to be transmitted, and is used to reset the environment, i.e., discard any changes made by the user on previous runs. The QEnvironmentHexEncoded packet is inspired on LLDB's extensions to the RSP. Details about it can be seen here: <https://raw.githubusercontent.com/llvm-mirror/lldb/master/docs/lldb-gdb-remote.txt> I decided not to implement the QEnvironment packet because it is considered deprecated by LLDB. This packet, on LLDB, serves the same purpose of QEnvironmentHexEncoded, but sends the information using a plain text, non-hex-encoded string. The other two packets are new. This patch also includes updates to the documentation, testsuite, and unit tests, without introducing regressions. gdb/ChangeLog: 2017-08-31 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS (Changes since GDB 8.0): Add entry mentioning new support for setting/unsetting environment variables on the remote target.

2017-08-31Unbreak gdb build on 32-bit host with ADI supportWeimin Pan2-11/+33
The problem of failing to build with arm-linux-gnueabihf-g++-4.8 was that type CORE_ADDR is of "unsigned long" on a 64-bit machine so it's OK to use %lx but is of type "unsigned long long" on a 32 bit system. Fixed the problem in three places - (1) use a temp variable of type CORE_ADDR as argument 3 when calling target_auxv_search() then assign its value to "blksize" and "nbits" in 2 calls; (2) redo adi_normalize_address() using masks and xor operators to calculate normalized address; (3) call paddress() to print CORE_ADDR in either printf_filtered() or error().

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.

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.

2017-08-29[GOLD] Reduce size of class SymbolAlan Modra4-70/+81
On 64-bit targets there is a 32-bit hole in symbol->u_, and another due to symbol flags exceeding 32 bits. By splitting the union, the total size of the class reduces by one 64-bit word. * symtab.h (Symbol): Split u_ into u1_ and u2_. Adjust accessors to suit. Move plt_offset_ before got_offsets_. * symtab.cc (Symbol::init_fields): Adjust for union change. (Symbol::init_base_output_data): Likewise. (Symbol::init_base_output_segment): Likewise. (Symbol::allocate_base_common): Likewise. (Symbol::output_section): Likewise. (Symbol::set_output_section): Likewise.

Since _bfd_elf_ifunc_get_synthetic_symtab is no longer called by x86 get_synthetic_symtab, it is now unused. This patch removes it. * elf-bfd.h (_bfd_elf_ifunc_get_synthetic_symtab): Removed. * elf-ifunc.c (_bfd_elf_ifunc_get_synthetic_symtab): Likewise.

2017-08-28define_command: Don't convert command name to lower caseSimon Marchi4-6/+40
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.

2017-08-28Fix bad offset calculation for R_AARCH64_TLSDESC_* relocs.Igor Kudrin7-6/+166
If a custom linker script with an unexpected relative layout of .got and .got.plt sections was used, gold might produce a wrong offset when applying R_AARCH64_TLSDESC_* relocations. This patch fixes the issue by calculating "got_tlsdesc_offset" in a more direct way. gold/ * aarch64.cc (Target_aarch64::Relocate::relocate_tls): Make got_tlsdesc_offset signed and fix its calculation. * testsuite/Makefile.am (aarch64_tlsdesc): New test. * testsuite/Makefile.in: Regenerate. * testsuite/aarch64_tlsdesc.s: New test source file. * testsuite/aarch64_tlsdesc.sh: New test script. * testsuite/aarch64_tlsdesc.t: New test linker script.
