New probe type: DTrace USDT probes. This patch adds a new type of probe to GDB: the DTrace USDT probes. The new type is added by providing functions implementing all the entries of the `probe_ops' structure defined in `probe.h'. The implementation is self-contained and does not depend on DTrace source code in any way. gdb/ChangeLog: 2015-02-7 Jose E.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

- probe->dofpr_nenoffs is-enabled probes whose program counters
are stored in 32bit words starting at probe->dofpr_addr +
eofftab[probe->dofpr_enoffidx].
However is-enabled probes are not probes per-se, but an
optimization hack that is implemented in the kernel in a very
similar way than normal probes. This is how we support
is-enabled probes on GDB:
- Our probes are always DTrace regular probes.
- Our probes can be associated with zero or more "enablers". The
list of enablers is built from the is-enabled probes defined in
the Probe section.
- Probes having a non-empty list of enablers can be enabled or
disabled using the `enable probe' and `disable probe' commands
respectively. The `Enabled' column in the output of `info
probes' will read `yes' if the enablers are activated, `no'
otherwise.
- Probes having an empty list of enablers are always enabled.
The `Enabled' column in the output of `info probes' will
read `always'.
It follows that if there are DTrace is-enabled probes defined for
some provider/name but no DTrace regular probes defined then the
GDB user wont be able to enable/disable these conditionals. */

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

/* Number of arguments in the probe. */
Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

'struct expression *' -> gdb::unique_xmalloc_ptr<expression> This patch makes parse_expression and friends return a unique_ptr instead of raw pointer [1]: typedef gdb::unique_malloc_ptr<expression> expression_up; and then adjusts the codebase throughout to stop using cleanups to manage lifetime of expression pointers. Whenever I found a structure owning an expression pointer, I made it store a unique_ptr instead of a raw pointer, which then requires using new/delete of the holding structure, instead of XNEW/xfree. [1] - I'd like to set the rule that types named with an "_up" suffix are unique_ptr typedefs. Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply because we still use xmalloc instead of new to allocate expression objects. Once that's changed, all we need to do is change the expression_up typedef and the smart pointer will then call delete instead of xfree. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_read_renaming_var_value): Use expression_up.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

ignore invalid DOF provider sections On x86-solaris 10, we noticed that starting a program would sometimes cause the debugger to crash. For instance: % gdb a (gdb) break adainit Breakpoint 1 at 0x8051f03 (gdb) run Starting program: /[...]/a [Thread debugging using libthread_db enabled] zsh: 24398 segmentation fault (core dumped) /[...]/gdb a The exception occurs in dtrace_process_dof_probe, while trying to process each probe referenced by a DTRACE_DOF_SECT_TYPE_PROVIDER DOF section from /lib/libc.so.1. For reference, the ELF section in that shared library providing the DOF data has the following characteristics: Idx Name Size VMA LMA File off Algn 14 .SUNW_dof 0000109d 000b4398 000b4398 000b4398 2**3 CONTENTS, ALLOC, LOAD, READONLY, DATA The function dtrace_process_dof gets passed the contents of that ELF section, which allows it to determine the location of the table where all DOF sections are described. I dumped the contents of each DOF section as seen by GDB, and it seemed to be plausible, because the offset of each DOF section was pretty much equal to the sum of the offset and size of the previous DOF section. Also, the offset + sum of the last section corresponds to the size of the .SUNW_dof section. Things start to break down when processing one of the DOF sections that has a type of DTRACE_DOF_SECT_TYPE_PROVIDER. It gets the contents of this DOF section via: struct dtrace_dof_provider *provider = (struct dtrace_dof_provider *) DTRACE_DOF_PTR (dof, DOF_UINT (dof, section->dofs_offset)); Said more simply, the struct dtrace_dof_provider data is at section->dofs_offset of the entire DOF contents. Given that the contents of SECTION seemed to make sense, so far so good. However, what SECTION tells us is that our DOF provider section is 40 bytes long: (gdb) print *section $36 = {dofs_type = 15, dofs_align = 4, dofs_flags = 1, dofs_entsize = 0, dofs_offset = 3264, dofs_size = 40} ^^^^^^^^^^^^^^ But on the other hand: (gdb) p sizeof (struct dtrace_dof_provider) $54 = 44 In other words GDB expected a bigger DOF section and when we try to fetch the value of the last field of that DOF section (dofpv_prenoffs)... eoffsets_s = DTRACE_DOF_SECT (dof, DOF_UINT (dof, provider->dofpv_prenoffs)); ... we end up reading data that actually belongs to another DOF section, and therefore irrelevant. This in turn means that the value of eofftab gets incorrectly set, since it depends on eoffsets_s: eofftab = DTRACE_DOF_PTR (dof, DOF_UINT (dof, eoffsets_s->dofs_offset)); This invalid address quickly catches up to us when we pass it to dtrace_process_dof_probe shortly after, where we crash because we try to subscript it: Program received signal SIGSEGV, Segmentation fault. 0x08155bba in dtrace_process_dof_probe ([...]) at [...]/dtrace-probe.c:378 378 = ((uint32_t *) eofftab)[...]; This patch fixes the issue by detecting provider DOF sections that are smaller than expected, and discarding the DOF data. gdb/ChangeLog: * dtrace-probe.c (dtrace_process_dof): Ignore the objfile's DOF data if a DTRACE_DOF_SECT_TYPE_PROVIDER section is found to be smaller than expected.

Remove symfile_complaints The complaint system seems to allow for multiple different complaint topics. However, in practice only symfile_complaints has ever been defined. Seeing that complaints.c dates to 1992, and that no new complaints have been added in the intervening years, I think it is reasonable to admit that complaints are specifically related to debuginfo reading.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units.

/* Implementation of the get_probe_address method. */
Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

/* Implementation of the compile_to_ax method. */
Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

/* Implementation of the disable_probe method. */
Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

Remove symfile_complaints The complaint system seems to allow for multiple different complaint topics. However, in practice only symfile_complaints has ever been defined. Seeing that complaints.c dates to 1992, and that no new complaints have been added in the intervening years, I think it is reasonable to admit that complaints are specifically related to debuginfo reading. This patch removes symfile_complaints and updates all the callers. Some of these spots should perhaps be calls to warning instead, but I did not make that change. gdb/ChangeLog 2018-05-23 Tom Tromey <tom@tromey.com> * complaints.c (symfile_complaints): Remove.

Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.

New probe type: DTrace USDT probes. This patch adds a new type of probe to GDB: the DTrace USDT probes. The new type is added by providing functions implementing all the entries of the `probe_ops' structure defined in `probe.h'. The implementation is self-contained and does not depend on DTrace source code in any way. gdb/ChangeLog: 2015-02-7 Jose E.

gdb: add back declarations for _initialize functions I'd like to enable the -Wmissing-declarations warning. However, it warns for every _initialize function, for example: CXX dcache.o /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’: /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations] _initialize_dcache (void) ^~~~~~~~~~~~~~~~~~ The only practical way forward I found is to add back the declarations, which were removed by this commit: commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 Author: John Baldwin <jhb@FreeBSD.org> Date: Sat Sep 9 11:02:37 2017 -0700 Remove unnecessary function prototypes. I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c

void _initialize_dtrace_probe ();
New probe type: DTrace USDT probes. This patch adds a new type of probe to GDB: the DTrace USDT probes. The new type is added by providing functions implementing all the entries of the `probe_ops' structure defined in `probe.h'. The implementation is self-contained and does not depend on DTrace source code in any way. gdb/ChangeLog: 2015-02-7 Jose E.

void
gdb: add back declarations for _initialize functions I'd like to enable the -Wmissing-declarations warning. However, it warns for every _initialize function, for example: CXX dcache.o /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’: /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations] _initialize_dcache (void) ^~~~~~~~~~~~~~~~~~ The only practical way forward I found is to add back the declarations, which were removed by this commit: commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 Author: John Baldwin <jhb@FreeBSD.org> Date: Sat Sep 9 11:02:37 2017 -0700 Remove unnecessary function prototypes. I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c

{
Convert DTrace probe interface to C++ (and perform some cleanups) This patch converts the DTrace probe interface (gdb/dtrace-probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct dtrace_probe' to 'class dtrace_probe', and a new 'class dtrace_static_probe_ops' to replace the use of 'dtrace_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the dtrace-probe interface. There are several helper functions used to parse parts of a dtrace probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I wasn't able to test these modifications because the current test framework for DTrace probes is not working.
