Subject: [gdb/testsuite] Generate .debug_aranges entry for dummy CU
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6a6429e19b0aa87f95cd20cb9df2715e6d3df6f1;p=binutils-gdb.git

[gdb/testsuite] Generate .debug_aranges entry for dummy CU

A best practise for DWARF [1] is to generate .debug_aranges entries for CUs
even if they have no address range.

Generate .debug_arange entries for the dummy CUs added by the DWARF assembler.

Tested on x86_64-linux.
