From 921b2bc73e6bc258e4ec8021e0cc4458a3b81e08 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Sun, 6 Jun 2021 09:53:42 -0400 Subject: [PATCH] gdb/testsuite: set sysroot in gdb.server/stop-reply-no-thread-multi.exp I get some random timeouts in this test due to big debug info taking a lot of time to read through gdbserver. When host and target are on the same machine, clear the sysroot parameter so that GDB reads the files from the local file system, as we already do in many tests. I agree with what Pedro says here: https://sourceware.org/pipermail/gdb-patches/2019-March/156568.html that if this is bad for us, it's also bad for users, so we should be fixing the slowness instead. But so far nobody seems to be working on it, and the testsuite timeouts are getting in the way, so I think this "set sysroot" is a net positive for now. Without this patch, the test takes over 2 minutes to run (most of it "downloading" libc debug info), with it it takes 10 seconds. gdb/testsuite/ChangeLog: * gdb.server/stop-reply-no-thread-multi.exp: Clear sysroot when host and target are local.
