Subject: gdb/testsuite: add DWARF 5 + split DWARF + type units board
X-Git-Tag: binutils-2_45~941
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=34f5a310b4f59546652947de751329a0ea765101;p=thirdparty%2Fbinutils-gdb.git

gdb/testsuite: add DWARF 5 + split DWARF + type units board

I'm currently fixing bugs and performance issues when GDB encounters
this particular configuration.  Since split DWARF + type units makes GDB
take some code paths not taken by any other board files, I think it
deserves to be its own board file.  One particularity is that the
produced .dwo files have a .debug_info.dwo section that contains some
ype units, in addition to the compile unit.

Add that board to make-check-all.sh.
