# -file-exec-and-symbols now takes two new (optional) options:
|
|
|
|
Synopsis
|
|
|
|
-file-exec-and-symbols <file> [-p <platform>] [-r <remote-file>]
|
|
|
|
Specify the executable file to be debugged. This file is the one from which the symbol table is also read.
|
|
When debugging remote targets specify a remote-file for execution and a file from which symbols are read.
|
|
The optional platform is the name of the platform, e.g., "remote-ios" or "ios-simulator". The remote-file
|
|
is the on-device path to the exe.

# -data-info-line
|
|
|
|
Synopsis
|
|
|
|
-data-info-line *<address>
|
|
-data-info-line <file>:<line>
|
|
|
|
Provides information about a source line. The input can be <address> like 0x12345678 or <file>:<line>
|
|
where file is a name of source file and line is the line number. As a result the command returns the following
|
|
fields:
|
|
start - address of the first instruction which refers to that source line
|
|
end - address of the last instruction which refers to that source line
|
|
file - the file name
|
|
line - the line number
|
|
The last two fields are useful in case you have specified a source line using its address.
|
|
|
|
Example:
|
|
-data-info-line *0x100000f80
|
|
^done,start="0x0000000100000f80",end="0x0000000100000f94",file="/Users/IliaK/p/hello.cpp",line="15"
|
|
|
|
-data-info-line hello.cpp:15
|
|
^done,start="0x0000000100000f80",end="0x0000000100000f94",file="/Users/IliaK/p/hello.cpp",line="15"

# -data-read-memory-bytes
|
|
|
|
Synopsis
|
|
|
|
-data-read-memory-bytes [--thread <thread-id>] [--frame <frame-index>] [-o <byte-offset>] <address> <count>
|
|
|
|
Where:
|
|
|
|
`address`
|
|
An expression specifying the start of the memory range to read.
|
|
`count`
|
|
Number of bytes to read.
|
|
`byte-offset`
|
|
Relative offset in bytes from `address` where reading should start.
|
|
`thread-id`
|
|
Integer identifier of the thread within which the expression should be evaluated,
|
|
if this option is omitted the currently selected thread will be used.
|
|
This option is not in the MI specification but is implemented by GDB.
|
|
`frame-index`
|
|
Index of the frame within which the expression should be evaluated,
|
|
if this option is omitted the currently selected frame will be used.
|
|
This option is not in the MI specification but is implemented by GDB.
|
|
|
|
Reads a block of memory from the specified range.
|
|
|
|
Note that currently this command works in an all-or-nothing fashion where it either reads the entire
|
|
block of memory successfully and returns it as a single block, or it returns an error. This doesn't
|
|
quite match up with the MI specification that says that subsets of the specified range may be
|
|
returned as individual blocks if only some of the memory within the specified range is accessible.
|
|
|
|
The result record for this command may contain one or more tuples representing the blocks of memory
|
|
that were read, where each tuple has the following fields:
|
|
|
|
`begin`
|
|
The start of the address range for this block (in hex notation).
|
|
`end`
|
|
The end of the address range for this block (in hex notation).
|
|
`offset`
|
|
Offset of this block from `address` (that was passed in as an argument).
|
|
`contents`
|
|
The actual data in this block (in hex notation).
|
|
|
|
Example:
|
|
|
|
(gdb)
|
|
-data-read-memory-bytes &array 4
|
|
^done,memory=[{begin="0x00007fffffffeccc",offset="0x0000000000000000",end="0x00007fffffffecd0",contents="01020304"}]

# =library-loaded notification
|
|
|
|
The =library-loaded notification has 3 extra fields:
|
|
symbols-loaded - indicates that there are symbols for the loaded library
|
|
symbols-path - if symbols are exist then it contains a path for symbols of the loaded library
|
|
loaded_addr - contains an address of the loaded library or "-" if address isn't resolved yet
|
|
|
|
For example:
|
|
=library-loaded,id="/Users/IliaK/p/hello",target-name="/Users/IliaK/p/hello",host-name="/Users/IliaK/p/hello",symbols-loaded="1",symbols-path="/Users/IliaK/p/hello.dSYM/Contents/Resources/DWARF/hello",loaded_addr="-"
|
|
=library-loaded,id="/usr/lib/dyld",target-name="/usr/lib/dyld",host-name="/usr/lib/dyld",symbols-loaded="0",loaded_addr="0x00007fff5fc00000"
