Andreas Arnez	87c336f60e	inf-ptrace: Do not stop memory transfers after a single word 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.	10 years ago

Anton Kolesov	0efcde634d	Add test name argument to get_valueof, get_integer_valueof and get_sizeof 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.	10 years ago
Andreas Arnez	a379284af2	linux-nat: Exploit /proc/<pid>/mem for writing 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.	10 years ago

Simon Marchi	7978d7c385	testsuite: Disable backslash_in_multi_line_command_test for old DejaGnus 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.	10 years ago
Simon Marchi	896c0c1ede	testsuite: Introduce dejagnu_version 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.	10 years ago

Keith Seitz	5f4d108508	c++/8218: Destructors w/arguments. 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.

Andrew Burgess	14ea2c1b23	ld: Track changes to default region LMA even for empty sections Given a linker script fragment like this: SECTIONS { . = 0x1000; .text : AT(0x100) { (.text) } .data : AT(0x200) { (.data) } .rodata : AT(0x300) { (.rodata) } } and an input file containing sections, '.text', '.data.1', and '.rodata', then we'd expect the linker to place '.text' and '.rodata' in the obvious way, and the '.data.1' orphan section would be located after the '.data' section (assuming similar section properties). Further, I believe that the expectation would be that the LMA for the orphan '.data.1' section would start from 0x200 (as there is no '.data' content). However, right now, the LMA for '.data.1' would be 0x101, following on from the '.text' section, this is because the change in LMA for the '.data' section is not noticed by the linker, if there's no content in the '.data' section. What can be even more confusing to a user (though the cause is obvious once you understand what's going on) is that adding some content to '.data' will cause the orphan '.data.1' to switch to an LMA based off of 0x200. This commit changes the behaviour so that an empty section that is in the default lma region, and sets its lma, will adjust the lma of the default region, this change will then be reflected in following sections within the default lma memory region. There's a new test to cover this issue that passes on a range of targets, however, some targets generate additional sections, or have stricter memory region size requirements that make it harder to come up with a generic pass pattern, that still tests the required features. For now I've set the test to ignore these targets. ld/ChangeLog: ldlang.c (lang_size_sections_1): Shortcut loop only after tracking changes to the default regions LMA. * testsuite/ld-elf/orphan-9.ld: Extend header comment. * testsuite/ld-elf/orphan-10.d: New file. * testsuite/ld-elf/orphan-10.s: New file. * NEWS: Mention change in behaviour.	10 years ago
Andrew Burgess	77f5e65ecf	ld: better handling of lma region for orphan sections When picking an lma_region for an orphan section we currently create a new lang_output_section_statement_type and then populate this with the orphan section. The problem is that the lang_output_section_statement_type has a prev pointer that links back to the previous output section. For non-orphan output sections, that are created in linker script order, the prev pointer will point to the output section that appears previous in linker script order, as you'd probably expect. The problem is that orphan sections are placed after processing the linker script, and so, in the case of an output section created for an orphan input section, the prev pointer actually points to the last output section created. This causes some unexpected behaviour when the orphan section is not placed after the last non-orphan section that was created. For example, consider this linker script: MEMORY { TEXT : ORIGIN = 0x200, LENGTH = 0x10 RODATA : ORIGIN = 0x400, LENGTH = 0x10 } SECTIONS { .text : {(.text) } AT>TEXT .data : AT(0x300) { (.data) } .rodata : { (.rodata) } AT>RODATA } If we are processing an orphan section '.data.1' and decide to place this after '.data', then the output section created will have a prev pointer that references the '.rodata' output section. The result of this is that '.data.1' will actually be assigned to the RODATA lma region, which is probably not the expected behaviour. The reason why '.data.1' is placed into the lma region of the '.rodata' section is that lma region propagation is done at the time we create the output section, based on the previous output section pointer, which is really just a last-output-section-created pointer at that point in time, though the prev point is fixed up later to reflect the true order of the output sections. The solution I propose in this commit is to move the propagation of lma regions into a separate pass of the linker, rather than performing this as part of the enter/exit of output sections during linker script parsing. During this later phase we have all of the output sections to hand, and the prev/next points have been fixed up by this point to reflect the actual placement ordering. There's a new test to cover this issue that passes on a range of targets, however, some targets generate additional sections, or have stricter memory region size requirements that make it harder to come up with a generic pass pattern, that still tests the required features. For now I've set the test to ignore these targets. ld/ChangeLog: ldlang.c (lang_leave_output_section_statement): Move lma_region logic to... (lang_propagate_lma_regions): ...this new function.
