From: Andrew Pinski <[email protected]>
Dwarf3/4/5 are really just extensions (well not fully) on
top of dwarf2 and the option --with-dwarf2 just changes the
default to emit dwarf 2, 3, 4, or 5 by default.
On the trunk, dwarf 5 is enabled by this configure option.
gcc/ChangeLog:
PR bootstrap/59447
* configure: Regenerate.
* configure.ac: Add (or later) to the --with-dwarf2
option documentation
* doc/install.texi: Likewise.
