Subject: gdb-rhbz2232086-refactor-selftest-support.patch
|
||
|
|
|
||
|
|
;; Back-port upstream commit 1f0fab7ff86 as part of a fix for
|
||
|
|
;; non-deterministic gdb-index generation (RH BZ 2232086).

gdb/testsuite: small refactor in selftest-support.exp
|
||
|
|
|
||
|
|
Split out the code that makes a copy of the GDB executable ready for
|
||
|
|
self testing into a new proc. A later commit in this series wants to
|
||
|
|
load the GDB executable into GDB (for creating an on-disk debug
|
||
|
|
index), but doesn't need to make use of the full do_self_tests proc.
|
||
|
|
|
||
|
|
There should be no changes in what is tested after this commit.
