2017-03-14inf-ptrace: Do not stop memory transfers after a single wordAndreas Arnez2-73/+77
When inf_ptrace_xfer_partial performs a memory transfer via ptrace with PT_READ_I, PT_WRITE_I (aka PTRACE_PEEKTEXT, PTRACE_POKETEXT), etc., then it currently transfers at most one word. This behavior yields degraded performance, particularly if the caller has significant preparation work for each invocation. And indeed it has for writing, in memory_xfer_partial in target.c, where all of the remaining data to be transferred is copied to a temporary buffer each time, for breakpoint shadow handling. Thus large writes have quadratic runtime and can take hours. Note: On GNU/Linux targets GDB usually does not use inf_ptrace_xfer_partial for large memory transfers, but attempts a single read/write from/to /proc/<pid>/mem instead. However, the kernel may reject writes to /proc/<pid>/mem (such as kernels prior to 2.6.39), or /proc may not be mounted. In both cases GDB falls back to the ptrace mechanism. This patch fixes the performance issue by attempting to fulfill the whole transfer request in inf_ptrace_xfer_partial, using a loop around the ptrace call. gdb/ChangeLog: PR gdb/21220 * inf-ptrace.c (inf_ptrace_xfer_partial): In "case TARGET_OBJECT_MEMORY", extract the logic for ptrace peek/poke... (inf_ptrace_peek_poke): ...here. New function. Now also loop over ptrace peek/poke until end of buffer or error.

2017-03-14Add test name argument to get_valueof, get_integer_valueof and get_sizeofAnton Kolesov2-7/+32
An optional parameter TEST has been added to get_hexadecimal_valueof in commit: https://sourceware.org/ml/gdb-patches/2016-06/msg00469.html This patch adds a similar optional parameter to other related methods that retrieve expression values: get_valueof, get_integer_valueof and get_sizeof. Thus tests that evaluate same expression multiple times can provide custom test names, ensuring that test names will be unique. gdb/testsuite/ChangeLog: 2017-03-14 Anton Kolesov <anton.kolesov@synopsys.com> * lib/gdb.exp (get_valueof, get_integer_valueof, get_sizeof): Add optional 'test' parameter.
2017-03-14linux-nat: Exploit /proc/<pid>/mem for writingAndreas Arnez2-16/+21
So far linux_proc_xfer_partial refused to handle write requests. This is still based on the assumption that the Linux kernel does not support writes to /proc/<pid>/mem. That used to be true, but has changed with Linux 2.6.39 released in May 2011. This patch lifts this restriction and now exploits /proc/<pid>/mem for writing to inferior memory as well, if possible. gdb/ChangeLog: * linux-nat.c (linux_proc_xfer_partial): Handle write operations as well.

2017-03-13Add asserts in target_fetch/store_registersSimon Marchi2-0/+9
We are currently assuming that regcache->ptid is equal to inferior_ptid when we call target_fetch/store_registers. These asserts just validate that assumption. Also, since the following patches will change target code to use regcache->ptid instead of inferior_ptid, asserting that they are the same should ensure that our changes don't have any unintended consequences. gdb/ChangeLog: * target.c (target_fetch_registers, target_store_registers): Add assert.

2017-03-13testsuite: Disable backslash_in_multi_line_command_test for old DejaGnusSimon Marchi2-0/+16
I noticed that backslash_in_multi_line_command_test in gdb.base/commands.exp failed on our RHEL6 servers. I traced it to the old version of DejaGnu (1.4.4). I have found that instead of receiving the expected: "print \\\nargc\n" gdb received: "print argc\n" thus breaking the test and its purpose. Versionof DejaGnu < 1.5 mess up sending "\\\n", it somehow gets replaced with a space. I found that the following commit in DejaGnu fixed the issue: http://git.savannah.gnu.org/cgit/dejagnu.git/commit/lib/remote.exp?id=3f39294f5cd6802858838d3bcc0ccce847ae17f2 Even though the commit is almost 10 years old, the following release of DejaGnu was only in 2013, which is why we still have systems with the old code. If the DejaGnu version is < 1.5, we just skip the test. gdb/testsuite/ChangeLog: * gdb.base/commands.exp (backslash_in_multi_line_command_test): Skip for versions of DejaGnu < 1.5.
2017-03-13testsuite: Introduce dejagnu_versionSimon Marchi3-7/+33
The next patch will require checking the DejaGnu version. There is already a test that does this, gdb.threads/attach-many-short-lived-threads.exp. This patch introduces a new procedure, dejagnu_version, and makes that test use it. The version number is "right-padded" with zeroes, to make sure that we always return a triplet (major, minor, patch). The procedure does not consider the DejaGnu versions from git. For example, if you used DejaGnu from its current master branch, the version would be "1.6.1-git", meaning that 1.6.1 will be the next release. I figured we'll cross that bridge when (and if) we get there. gdb/testsuite/ChangeLog: * lib/gdb.exp (dejagnu_version): New proc. * gdb.threads/attach-many-short-lived-threads.exp (bad_dejagnu): Use dejagnu_version.
2017-03-13Merge libiberty: Initialize d_printing in all cplus_demangle_fill_* functions.mark4-0/+17
While integrating the d_printing recursion guard change into gdb I noticed we forgot to initialize the demangle_component d_printing field in cplus_demangle_fill_{name,extended_operator,ctor,dtor}. As is done in cplus_demangle_fill_{component,builtin_type,operator}. It happened to work because in gcc all demangle_components were allocated through d_make_empty. But gdb has its own allocation mechanism (as might other users). libiberty/ChangeLog: * cp-demangle.c (cplus_demangle_fill_name): Initialize demangle_component d_printing. (cplus_demangle_fill_extended_operator): Likewise. (cplus_demangle_fill_ctor): Likewise. (cplus_demangle_fill_dtor): Likewise. gdb/ChangeLog: * cp-name-parser.y (make_empty): Initialize d_printing to zero.

First, need to match against just the CPU name, not the whole triplet. Otherwise, the test picks up "*le-*" pattern from x86_64-apple-darwin triplet. Second, it should be testing for $target, not $host. Host may be little endian by default, and the sysroot directory layout shouldn't depend on whether it is built on LE or BE machine. * emulparams/elf32ppccommon.sh (LIBPATH_SUFFIX): Set from target cpu, not host.

2017-03-10c++/8218: Destructors w/arguments.Keith Seitz4-11/+38
For a long time now, c++/8218 has noted that GDB is printing argument types for destructors: (gdb) ptype A type = class A { public: ~A(int); } This happens because cp_type_print_method_args doesn't ignore artificial arguments. [It ignores the first `this' pointer because it simply skips the first argument for any non-static function.] This patch fixes this: (gdb) ptype A type = class A { public: ~A(); } I've adjusted gdb.cp/templates.exp to account for this and added a new passing regexp. gdb/ChangeLog PR c++/8218 * c-typeprint.c (cp_type_print_method_args): Skip artificial arguments. gdb/testsuite/ChangeLog PR c++/8128 * gdb.cp/templates.exp (test_ptype_of_templates): Remove argument type from destructor regexps. Add a branch which actually passes the test. Adjust "ptype t5i" test names.
