similar to: Building with debug symbols and different optimisation levels

I am often asked what optimisations "our" compiler performs at each level. But "our" compiler is actually CLang/LLVM which we have retargeted to our proprietary target. Most of the work we do is in maintaining our target specific backend. Certainly there are optimisations that we do to take best advantage of our instruction set during lowering and instruction selection, and

Right but then you'll have to call each opt level. Have u looked in the pass manager?

Hi, I'm trying to build Samba from source on a RHEL version 8 server. I installed all the necessary packages and untarred the source for Samba version 4.6.10. In the past I have been able to successfully build and install Samba version 4.13.17 on a RHEL version 7 server with Python2. Here I believe I am using Python3, but I cannot seem to get past the configure command: [root at v2ecsqapp09

I don't think you are going to have much luck getting 4.17 working on CentOS 7. We recently moved from CentOS 7 (4.13) to Rocky Linux 8 (4.16) and the install process was much easier.

Ok now, but did 4.10.16? I was just trying to rebuild their source RPM. Trying 4.17 on the command line (with python3) gives me: > [root at srvlxfs2 samba-4.17.4]# ./configure > Setting top to : > /root/rpmbuild/BUILD/samba-4.17.4 > Setting out to : > /root/rpmbuild/BUILD/samba-4.17.4/bin > Checking for 'gcc' (C

​No, sorry, it's actually failing on "configure" which this script calls. I should have been more clear. ./configured is failing at step: ​*Checking uname sysname type* It's obviously missing some app/header/library, but reading through all the breakpoints listed in the error (re-pasted below) I can't make out from the code what it's looking for, and the config.log

I am trying to build Samba 4.6.4 on an ARM 7 Cortex based router (Netgear R8000), running *DD-WRT v3.0-r31980M kongac (05/11/17)* I'm working with some folks via the DDWRT, but we're running into an issue trying to build from source. I have python 2.7 already installed on the router, and I'm executing the install_with_python.sh script. ./install_with_python.sh /opt/test/samba-4.6.4

I agree, it's much clearer, it just takes runs at multiple opt levels and therefore I don't find it to be a "one stop shop".

Hi Sanjoy, Yes these are C tests (from 'gcc.c-torture/execute'), and as I indicated in my original message, the tests are not valid because the behaviour is undefined. However, it was while investigating these new failures in these tests that I realised that this optimisation existed. The optimisation itself is perfectly valid, but it does mean that integer underflow will no longer be

21 jun 2014 the version numbers changed (samba-4.1.8), but the problem remains exactly the same: waf configure continues to break at krb5. frank smith 31 may 2014 greetings, in the (relatively distant) past, i several times downloaded, built, and ran the then-current version of samba with little to no problem. i recently experienced similar successful results with samba-3.6.23. i

Dear Samba experts, I tried to install the latest Samba release the way I did it always, i.e. starting with: ./configure --prefix=/usr/local/samba \ --with-piddir=/usr/local/samba/var/run \ --with-syslog \ --with-quotas \ --with-acl-support \ --enable-debug \ --enable-cups \ --enable-selftest \

Hello all: I am trying to build smbtorture using static linked libraries. The samba source code I have is samba-4.1.13 for configure, I did: waf configure --builtin-libraries=ALL for build, I did: waf build --targets=smbtorture (so that it only build target smbtorture) But, the waf build fails immediately. Then, I tried to only link with lib talloc and tevent statically, so I did: waf

Dear All, I would like to minimise a nonlinear function subject to linear inequality constraints as part of an R program. I have been using the constrOptim function. I have tried all of the methods that come with Optim, but nothing finds the correct solution. If I use the correct solution as the vector of starting values, though, my program does output the correct solution and optimum - the

I am unable to compile Samba 4.4.7, 4.5.1 or 4.5.3 on Solaris 11. I had been able in the past so maybe an update to GCC broke something. GCC 4.8 is the default. I then installed GCC 4.9. /usr/bin/gcc is a symlink to /usr/gcc/4.9/bin/gcc. I compiled the latest openldap (client only) to the samba target directory. Set environmental variables so the krb5.h and openldap would be found.

When I'm trying to understand how or why the back end does something I've found the -view-* options to llc to be useful. It's not ideal, because "clang" doesn't take those options, so I have to invoke first "clang" and then "llc", and sometimes that combination gives different final code from invoking just "clang", but usually I can construct

With LLVM v5.0, I found failures in some of the 'gcc.c-torture/execute' tests due to a change in the optimisation where undefined behaviour is involved. The tests that fail are the '20040409-[123].c' tests. The underlying failure is due to the optimisation of the following: int test2(int x) { return x + INT_MIN; } from using an ADD instruction to using an OR instruction.

Hi there, I have a piece of Matlab code I use to optimise a trding strategy. If there are any Matlab/R specialists out there, I would appreciate your help in doing the exact same optimisation in R. I suspect I would use nlm() in R but am not sure where to define my constraints. I have attached my Matlab code below for reference. Many thanks. Constraints function [c,ceq]=TriskellConstraints(X)
