2019-10-02gdb: Change a VEC to std::vector in btrace.{c,h}Andrew Burgess1-4/+1
Replace a VEC with a std::vector in btrace.h, and update btrace.c to match. It is worth noting that this code appears to be currently untested by the GDB testsuite. I've tried to do a like for like replacement when moving to std::vector, with minimal refactoring to try and avoid introducing any bugs. As the new vector is inside a union I've currently used a pointer to vector, which makes the code slightly uglier than it might otherwise be, but again, due to lack of testing I'm reluctant to start refactoring the code in a big way. gdb/ChangeLog: * btrace.c (btrace_maint_clear): Update to handle change from VEC to std::vector. (btrace_maint_decode_pt): Likewise, and move allocation of the vector outside of the loop. (btrace_maint_update_packets): Update to handle change from VEC to std::vector. (btrace_maint_print_packets): Likewise. (maint_info_btrace_cmd): Likewise. * btrace.h: Remove use of DEF_VEC_O. (typedef btrace_pt_packet_s): Delete. (struct btrace_maint_info) <packets>: Change fromm VEC to std::vector. * gdbsupport/btrace-common.h: Remove 'vec.h' include.
2019-07-09Rename common to gdbsupportTom Tromey1-2/+2
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

2018-04-13btrace: set/show record btrace cpuMarkus Metzger1-2/+4
Add new set/show commands to set the processor that is used for enabling errata workarounds when decoding branch trace. The general format is "<vendor>:<identifier>" but we also allow two special values "auto" and "none". The default is "auto", which is the current behaviour of having GDB determine the processor on which the trace was recorded. If that cpu is not known to the trace decoder, e.g. when using an old decoder on a new system, decode may fail with "unknown cpu". In most cases it should suffice to 'downgrade' decode to assume an older cpu. Unfortunately, we can't do this automatically. The other special value, "none", disables errata workarounds. gdb/ * NEWS (New options): announce set/show record btrace cpu. * btrace.c: Include record-btrace.h.

2017-05-30btrace: Remove struct btrace_function::flow.Tim Wiederhake1-3/+0
This used to hold a pair of pointers to the previous and next function segment in execution flow order. It is no longer necessary as the previous and next function segments now are simply the previous and next elements in the vector of function segments.

These are no longer needed and might hold invalid addresses once we change the vector of function segment pointers into a vector of function segment objects where a reallocation of the vector changes the address of its elements.

2017-02-14btrace: Use binary search to find instruction.Tim Wiederhake1-0/+7
Currently, btrace_find_insn_by_number will iterate over all function call segments to find the one that contains the needed instruction. This linear search is too slow for the upcoming Python bindings that will use this function to access instructions. This patch introduces a vector in struct btrace_thread_info that holds pointers to all recorded function segments and allows to use binary search. The proper solution is to turn the underlying tree into a vector of objects and use indices for access. This requires more work. A patch set is currently being worked on and will be published later.

2015-11-17Type-safe wrapper for enum flagsPedro Alves1-3/+7
This patch fixes C++ build errors like this: /home/pedro/gdb/mygit/cxx-convertion/src/gdb/linux-tdep.c:1126:35: error: invalid conversion from ‘int’ to ‘filterflags’ [-fpermissive] | COREFILTER_HUGETLB_PRIVATE); ^ This is a case of enums used as bit flags. Unlike "regular" enums, these values are supposed to be or'ed together. However, in C++, the type of "(ENUM1 | ENUM2)" is int, and you then can't assign an int to an enum variable without a cast. That means that this: enum foo_flags flags = 0; if (...) flags |= FOO_FLAG1; if (...) flags |= FOO_FLAG2; ... would have to be written as: enum foo_flags flags = (enum foo_flags) 0; if (...) flags = (enum foo_flags) (flags | FOO_FLAG1); if (...) flags = (enum foo_flags) (flags | FOO_FLAG2); which is ... ugly. Alternatively, we'd have to use an int for the variable's type, which isn't ideal either. This patch instead adds an "enum flags" class. "enum flags" are exactly the enums where the values are bits that are meant to be ORed together. This allows writing code like the below, while with raw enums this would fail to compile without casts to enum type at the assignments to 'f': enum some_flag { flag_val1 = 1 << 1, flag_val2 = 1 << 2, flag_val3 = 1 << 3, flag_val4 = 1 << 4, }; DEF_ENUM_FLAGS_TYPE(enum some_flag, some_flags) some_flags f = flag_val1 | flag_val2; f |= flag_val3; It's also possible to assign literal zero to an enum flags variable (meaning, no flags), dispensing either adding an awkward explicit "no value" value to the enumeration or the cast to assignments from 0. For example: some_flags f = 0; f |= flag_val3 | flag_val4; Note that literal integers other than zero do fail to compile: some_flags f = 1; // error C is still supported -- DEF_ENUM_FLAGS_TYPE is just a typedef in that case. gdb/ChangeLog: 2015-11-17 Pedro Alves <palves@redhat.com> * btrace.h: Include common/enum-flags.h.

2015-03-04record-full/record-btrace: software/hardware breakpoint trapPedro Alves1-0/+4
This adjusts the record targets to tell the core whether a trap was caused by a breakpoint. Targets that can do this should report breakpoint traps with the PC already adjusted, so this removes the re-incrementing record-full was doing. These targets need to be adjusted before process_stratum targets beneath are, otherwise target_supports_stopped_by_sw_breakpoint, etc. would fall through to the target beneath while recording/replaying, and the core would get confused. Tested on x86-64 Fedora 20, native and gdbserver. gdb/ChangeLog: 2015-03-04 Pedro Alves <palves@redhat.com> * btrace.h: Include target/waitstatus.h.

2015-03-03btrace: compute line range when printingMarkus Metzger1-3/+0
The "record function-call-history" command prints the range of source lines for a function segment when given the /l modifier. This information is computed for the entire execution history when processing the recorded branch trace. To speed up the initial trace processing, we compute the information when we print a function segment and only if requested. The computation is fast enough (due to the limited scope) that it is not worth storing the data in struct btrace_function, anymore. gdb/ * btrace.h (btrace_function) <lbegin, lend>: Remove. * btrace.c (ftrace_debug): Do not print the line range.

2015-02-09record-btrace: indicate gapsMarkus Metzger1-6/+34
Indicate gaps in the trace due to decode errors. Internally, a gap is represented as a btrace function segment without instructions and with a non-zero format-specific error code. Show the gap when traversing the instruction or function call history. Also indicate gaps in "info record". It looks like this: (gdb) info record Active record target: record-btrace Recording format: Branch Trace Store. Buffer size: 64KB.

2014-01-16btrace: change branch trace data structureMarkus Metzger1-34/+203
The branch trace is represented as 3 vectors: - a block vector - a instruction vector - a function vector Each vector (except for the first) is computed from the one above. Change this into a graph where a node represents a sequence of instructions belonging to the same function and where we have three types of edges to connect the function segments: - control flow - same function (instance) - call stack This allows us to navigate in the branch trace. We will need this for "record goto" and reverse execution. This patch introduces the data structure and computes the control flow edges. It also introduces iterator structs to simplify iterating over the branch trace in control-flow order. It also fixes PR gdb/15240 since now recursive calls are handled correctly. Fix the test that got the number of expected fib instances and also the function numbers wrong. The current instruction had been part of the branch trace. This will look odd once we start support for reverse execution. Remove it. We still keep it in the trace itself to allow extending the branch trace more easily in the future. 2014-01-16 Markus Metzger <markus.t.metzger@intel.com> * btrace.h (struct btrace_func_link): New.
