similar to: [LLVMdev] SimplifyLibCalls Pass -- Help!

Hi All, I finally got around to cleaning up my proposal to merge `SimplifyLibCalls` into `InstCombiner`. There is still an open question or two and I am sure there are parts that could be better specified, but this is good enough to discuss. Feedback is most welcome. Abstract ======== This proposal is an attack plan for PR11895 [1]. Currently within LLVM we have two passes that are used to

Hi, It looks like SimplifyLibCalls has a tendency to emit calls to libm functions without checking with TLI whether these calls are available. For example, PowOpt has this code: struct PowOpt : public UnsafeFPLibCallOptimization { PowOpt(bool UnsafeFPShrink) : UnsafeFPLibCallOptimization(UnsafeFPShrink) {} virtual Value *callOptimizer(Function *Callee, CallInst *CI, IRBuilder<> &B)

I'm trying to use nls() to fit an exponential decay with an unknown offset in the time (independent variable). (Perhaps this is inherently very difficult?). > decay.pl <- nls (amp ~ expn(b0,b1,tau,t0,t), data = decay, + start = c(b0=1, b1=7.5, tau=3.5, t0=0.1), trace=T) Error in nlsModel(formula, mf, start) : singular gradient matrix at initial parameter estimates

Hi, In the third edition of the MASS book, Chapter 8, Page 252 ~ 253. I tried applying the same technique on using a negative exponential model (as suggested in Exercise 1), and trying to get a confidence interval. What I have changed is follows: expn <- function(b0, b1, th, x) { temp <- exp(-x/th) model.func <- b0 + b1 * temp # Differentiate temp derive.negexp <- (x

Dear All, I have two machines, a Centos 3.4 machine and a Centos 4.1 machine. I have used the same sendmail.mc file on each, and 3.4 machine does plain SMTP auth with no problems, compiling the same mc file on the 4.1 machine gives this error: xxxxx [x.x.x.x] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA in the logs, it doesn't even try to authenticate, the cyrus sasl rpm

Hi, I've just installed xulrunner-devel from yum, but there are following header files cannot be found in xulrunner-sdk-1.9/sdk/include: mozilla-config.h mozilla-config32.h prtypes.h The include/xulrunner-sdk-1.9 constains those above header files, I did link to them, but xulrunner-sdk-1.9/system_wrappers/prtypes.h has a problem as well: #pragma GCC system_header #pragma GCC visibility

Hello, I am trying to cross-compile libc++ from my x86_64 linux system to armv7hf. We have our own gcc compiler that we build with crosstools-ng (based on gcc 6.3.0) and I set my environment like this: CC=armv7a-plex-linux-gnueabihf-gcc CXX=armv7a-plex-linux-gnueabihf-g++ CFLAGS=-fPIC -DPIC -mfloat-abi=hard -march=armv7-a -Os -mfpu=vfpv3-d16 --sysroot=<path> CXXFLAGS=-fPIC -DPIC

Hi, I have Sendmail configured to use STARTTLS for authentication. On all internet connections and computers (that I have tested) works connection over encrypted SMTP flawlessly. Today I was setting up mail client on PC of my customer and standardily checked boxes, that I want to use SSL for POP3 and SMTP. Next I wanted to check configuration (by sending email from this mailbox to this mailbox)

Folks I am using sendmail as my mail server. SELINUX is disabled. I observe messages in Centos 7 (and 6) in /var/log/messages, similar to: saslauthd[2765]: do_auth : auth failure: [user=bettie] [service=smtp] [realm=] [mech=pam] [reason=PAM auth error] I guess that this is because somebody tried to access one of the SMTP ports with a logon attempt. This is understandable; there are

I am getting large numbers of these types of messages in my maillog files: somehost.hotmail.com [65.54.246.97] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA on both of our external machines beginning on the same date. These hosts sit on different netblocks and on both machines the sendmail.cf files date from Jan 09, 2007. The last successfull connection from any hotmail acocunt

I configured Dovecot on our mail server under Centos 5.3 (I think) some while ago now (about 2 years) and, to the best of my knowledge,it had been working correctly all that time. However, one of the team wanted to use webmail while away from base and found that, although he could receive emails OK, he was unable to reply or send fresh emails. When he pressed Send he got a message ?Authentication
