Current status

• Targeted release: Fedora 31
• Last updated: 2019-05-03
• Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Create subpackage in gdb source package called gdb-minimal that will contain 2 files:

• /usr/bin/gdb.minimal — GDB executable built without optional unneeded features
• /usr/bin/gdb-add-index — Executable script shared with gdb-headless package (modified to fallback to gdb.minimal if exists)

debuginfo code in RPM needs just gdb-add-index and that one doesn't need any syntax highlight or python plugins to work.

As of Apr 26, following packages would disappear from buildroot:

boost-regex-1.69.0-6.fc30.x86_64
ctags-5.8-25.fc30.x86_64
gdbm-libs-1:1.18-4.fc30.x86_64

• RPM download size for buildroot preparation will go down from 77M to 54M
• installed buildroot size will go down from 339M to 249M
