I have a new problem: Register RBP is used in a function foo. (I am not allocating RBP to any virtual register, the instances of RBP in function foo are in the machine code when my register allocator starts.) Function foo calls function bar. Register RBP is not saved across the call, though it is live after the call. Function bar includes a virtual register. The code that I'm using to

I submitted the problem report to clang's bugzilla but no one seems to care so I have to send it to the mailing list. clang 3.7 svn (trunk 229055 as the time I was to report this problem) generates slower code than 3.5 (Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)) for the following code. It is a "8 queens puzzle" solver written as an educational example. As

Hi Greetings to all Is my first post in this forum sorry for my english Many compliment to all developers for great work in Wine Profili2 is the most famous Windows software for designe airfoil profile for RC airplane models. Some times ago I have installed it in ubuntu 10.10 by Wine(1.3.5) with success This software use an mdb file First I have installed Profili download in this web site

The regressions in the performance of generated code, introduced by the llvm 3.6 release, don't seem to be limited to this 8 queens puzzle" solver test case. See... http://www.phoronix.com/scan.php?page=article&item=llvm-clang-3.5-3.6-rc1&num=1 where a bit hit in the performance of the Sparse Matrix Multiply test of the SciMark v2.0 benchmark was observed as well as others.

Using the SciMark 2.0 code from http://math.nist.gov/scimark2/scimark2_1c.zip compiled with the same... make CFLAGS="-O3 -march=native" I am able to reproduce the 22% performance regression in the run time of the Sparse matmult benchmark. For 10 runs of the scimark2 benechmark, I get 998.439+/-0.4828 with the release llvm clang 3.5.1 compiler and 1217.363+/-1.1004 for the current

I'm trying to build the 1.4.0 development version of R for Windows. I'll be posting problems as they arise, until I give up (or succeed), or someone asks me to stop. 1. I don't have zlib, the compression library. The source file gnuwin32/unzip/WHERE says to get it from ftp://ftp.info-zip.org/pub/infozip/zlib/zlib.html; that web site says it has been closed and redirects me to

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, Xandros 3.0.1 OCE (Debian based). ./configure executed without problem (once I installed bison++). Then 'make depend && make' resulted in the errors below. Apologies for the length of the mail, but I don't want to miss out anything which may be vital :) Any suggestions would be gratefully received. Kind regards,

Hello, LLVM guys. While compliling llvm-as(LLVM ver. 1.9), I got an error looks like this: (I haven't modified any part in llvm-as and I just compiled it but....) ------------------------------------------------------------------- Debug Error!

I have a dataset of the form below, consisting of one unique ID per row, followed by a series of visit dates. At each visit there are values for 3 dichotomous variables. Of the 8 different possible combinations of the three variables, 4 are "abnormal" and the remaining 4 are "normal". Everyone starts out abnormal, and then either continues to be abnormal at subsequent visits,

I'm attempting to modify a parser generator to emit LLVM code instead of C. So far the experience has been trivial, but I am now running into an error regarding labels that I can't seem to solve. Situation 1: A label is used immediately after a void function call (l6 in this case): <snip> %tmp26 = load i32* @yybegin, align 4 %tmp27 = load i32* @yyend, align 4 call void

Hello, The lack of debian packages for 0.9.13 have made me decide to compile from source instead. So I uninstalled all wine files and downloaded the sources. I'm using a system based mostly on Debian Sarge, but with some backports. I ran ./configure and there were some packages I had to get, but soon it worked well. When I tried make depend the problems started. This is the output I get
