Hello,
In one of my projects, I need to determine automatically what are the names
and types of data fields manipulated by functions in binary code of a given
program (e.g. Linux kernel).
I found that RTL dumps contains most of information I need in a form very
close to the one of the binary code.
Status
==
GCC 7 is in regression and documentation fixes mode and it is time
to think about backports you want/need to do for GCC 7.3. The plan
is to do a release candidate for GCC 7.3 in the second week of January
following by a release a week after that.
As usual the branch is in good sha

As Vladimir said, the cache makes this kind of analysis much more
tricky. It's not necessarily the case that memory=bad and
register=good. Since there a
Hi David,
Thanks for your teaching!
I am a newbie in compiler area, I only learned Compiler Principle in
2002 https://www.leetcode.cn/2017/12/ilove-compiler-principle.html
But I like to practice and learn :)

Where is this work keeping it's working archive? On gitlab?

Hi Leslie,
I suggest adding these 3 papers to your reading list.

The master is on grelber in my basement. Copies are synced by Joseph, another
GCCer named Jason Merrill, and myself on snark.

Hi Michael,
Thanks for your sharing!
I will read the papers as you suggested, and I asked Quantum Computing
professionals about solving the NP-complete problem
https://github.com/epiqc/ScaffCC/issues/14 but GCC's IRA and LRA proved
that there is a solution in SSA form for classical computer.
Hi Matthias,
Thanks for your hint!
It is just for learning and practicing for me, just like migrate
