gdb/testsuite: Add is-stmt support to the DWARF compiler
This commit adds the ability to set and toggle the DWARF line table
is-stmt flag.
A DWARF line table can now be created with the attribute
'default_is_stmt' like this:
lines {version 2 default_is_stmt 0} label {
...
}
If 'default_is_stmt' is not specified then the current default is 1,
which matches the existing behaviour.
Inside the DWARF line table program you can now make use of
{DW_LNS_negate_stmt} to toggle the is-stmt flag, for example this
meaningless program:
lines {version 2 default_is_stmt 0} label {
include_dir "some_directory"
file_name "some_filename" 1
program {
{DW_LNS_negate_stmt}
{DW_LNE_end_sequence}
}
}
This new functionality will be used in a later commit.
gdb/testsuite/ChangeLog:
* lib/dwarf.exp (Dwarf::lines) Add support for modifying the
is-stmt flag in the line table.
