This patch adds support the command 'source info' as follows:
(lldb) help source info
Display source line information (as specified) based on the current executable's
debug info.
Syntax: source info <cmd-options>
Command Options Usage:
source info [-c <count>] [-s <shlib-name>] [-f <filename>] [-l <linenum>] [-e <linenum>]
source info [-c <count>] [-s <shlib-name>] [-n <symbol>]
source info [-c <count>] [-a <address-expression>]
-a <address-expression> ( --address <address-expression> )
Lookup the address and display the source information for the corresponding
file and line.
-c <count> ( --count <count> )
The number of line entries to display.
-e <linenum> ( --end-line <linenum> )
The line number at which to stop displaying lines.
-f <filename> ( --file <filename> )
The file from which to display source.
-l <linenum> ( --line <linenum> )
The line number at which to start the displaying lines.
-n <symbol> ( --name <symbol> )
The name of a function whose source to display.
-s <shlib-name> ( --shlib <shlib-name> )
Look up the source in the given module or shared library (can be specified
more than once).
For example:
(lldb) source info --file x.h
Lines for file x.h in compilation unit x.cpp in `x
[0x0000000100000d00-0x0000000100000d10): /Users/dawn/tmp/./x.h:10
[0x0000000100000d10-0x0000000100000d1b): /Users/dawn/tmp/./x.h:10
The new options are used to fix the MI command:
-symbol-list-lines <file>
which didn't work for header files because it called:
target modules dump line-table <file>
which only dumps line tables for a compilation unit.
The patch also fixes a bug in the error reporting when no files were supplied to the command. Previously you'd get:
(lldb) target modules dump line-table
error:
Syntax:
error: no source filenames matched any command arguments
Now you get:
error: file option must be specified.
