Subject: Interpreting -fmem-report
Date: Tue, 4 Jan 2022 15:08:53 -0500	[thread overview]
Message-ID: <CAG_eJLd6qbwY+583poJVW4AbPd+tWa+qEfRBWOBYjsfj7LoRDg@mail.gmail.com> (raw)

Hi all,

I am interested in -fmem-report to help diagnose an issue
with memory thrashing during a parallel build.  Ech separate
compilation if and of itself is not enough to cause the thrash,
but when they're added up over a parallel compile, things go
south.

So I want to collect total memory usage of GCC during a
compilation and then sum them over the last 16 or so GCC
invocations we have.  But I am having a hard time figuring
out the total usage.  I see nothing obvious.  Any hints?

Thanks,

Tom
